I have been running a small DC of Titans, and have designed and manufactured a cooler bracket modification that mounts the cooler to the board in 4 points instead of the current 3 points.
This allows for more stable and even pressure, and has allowed for some flaky dies to start working. It also allows for you to put what ever heatsink solution you want on all of the DC/DC's.
Also your original hold down plate is unmodified, and unused.
This is a simple bolt in modification:
You remove the existing 3 point cooler hold down. Remove the cooler and clean it and the chip for re-pasting.
Remove the 2 alignment screws in the smaller aluminum plate.
Remove the remaining 2 screws that are holding the board down.
Remove and clean the top & bottom of the PC board.
Carefully remove the yellow label on the DC/DC modules, and install your heatsinks from another source. You must install 8 heatsinks. call or email me for suggestions.
Move some of your now now unused thermal pads to better support the bottom of the board.
Reinstall the board carefully making sure to align the 4 holes with the 4 board supports.
Take each of my supplied brackets and screw then to the topside of the small aluminum cooler plate using the 2 short screws that held the PC Board to the cube, and 2 of your case screws.
Re-paste the cooler to chip area with quality thermal paste.
Put 2 of the long screws I provided in the kit, and 2 of the 3 long screws that held down the old mount into the 4 outer holes on the cooler mount brackets, and carefully lower the cooler onto the PC Board aligning the 4 long screws with the 4 mounting holes. It is easier to mount the cooler facing the opposite direction from oem installation, but you can do it either way.
When tightening the screws tighten them in a cross pattern and slightly adjust and confirm that the cooler is squarely on the chip.
Do not over tighten the screws. Tighten them just enough to insure that the cooler does not moving and there is no gap between the chip and cooler form any angle.
the screws I provided are allen wench, but the torx works on them other than to snug, but again tighten evenly and only what is needed so you don't as Lightfoot says "Taco the board"
Test the cube at this point, and make any adjustment if needed. if not needed let the cube run for 10 minutes or so, and then shut down.
While warm apply gentle pressure to the DC/DC heatsinks you installed to insure a good adhesion.
Re-install the cube cover using the 2 screws you removed from the alignment plate to replace the two case screws that you used to mount the brackets.

This cooling solution works equal to, or better that the factory application, but is better at insuring even pressure, and has allowed some dies that drop off, or have needed to be set at a slower speed, to run stady and faster again.
If you want to enhance the cooling more add a additional, or better case fan.
You can also add a additional heatsink to the cooler plate between my brackets under the heatpipe heatsink if you want to.
                                
I am selling these brackets for $10.00 per cube, and $8.50 shipping in USA, more for elsewhere, for up to 20 bracket sets. I am also including 2 black hold down screws in the pictures below for each kit.
When you have reassembled the cube you will have 1 long screw left over.

Anyone who knows me can verify that I have been running multiple Titans for over 18 months. I was active on the KNC forums, and Litecointalk forums.

The first picture is what each cube kit consists of. all of the other parts are with your titan cube now.

I prefer running my Titans in my basement cool room...
Those looks nice though - good luck with sale.

Nice :D sell on amazon pleasee :D

Why are you telling him to sell on amazon?

I have 12 coming from him in the mail.

Also note you need the small heat sinks in that the massive KNC heat sink used to use cover them and use foam to transfer. (silly imho) . A better fan also would be prudent imho.

Last but not least for any newbies if you use this mod you will need to 're-paste' the thermal compound on the chip. Not a big deal but just saying.

Now if I can somehow find the time to do this.

ie an afternoon of calm and quiet to dork with this etc

4 kits are on the way, paid in bitcoins yesterday. I will post here when I receive the package.

I want to prepare my 4 cubes to survive to the summer heat, last summer it was shutted down most of the time.

I'm in Minnesota ...basement big limestone blocks...I simply move air...at about 20 bucks a month for a push in and push out fan system...heat rises in basement breeze
takes it out a shutter exhaust (Hood from amazon and fan was Menards online only) you can see my 8 slot sub panel to my 100 amp (whimpy) service too ...man did
I drink the kool aid :)



lostgonzo.imgur.com (http://lostgonzo.imgur.com)

so anyway KISS principle keep it simple stupid seemed to do ok if you have upper Midwest climate

Also note his heatsink arrangements on his X bracket (ask) i got the paste etc to re-paste and the small heatsinks ....i also got the bigger louder fan from the
Swedish guy upgrade  titan video on YouTube

...so now just the time to rip into (to start) my 1 die working cube sacrifice likely to the asic gods) but hell that an't gonna happen for at least 1 week :( If I did not post

from work (the bosses don't care) I'd never get even that done



but a/c vs miners (with help from summer heat) always win....so yeah i may have to shut down on the really hot days me thinks (my units are 17 months old now)

anyway my arrangement works..if it stops working I have 2 more windows I can put 2 more fans up ..1 push and one shutter fan it out

good luck

All paid orders are shipped out. Please leave me some Trust when you get your order.
I have enough brackets kits for 42 more cubes. If those go quick I will have another 250 made, but it could take 2 weeks.
 
Pm me if you have any questions when you are doing your mods.

Thanks  :)

This way of cooling may be useful for you and others.
I have separated a small area with a window inside. The miner fans get fresh air from outside and blow the warm air into the room. No extra fans required. another window is open to let the warm air out.

The advantage is, that no preheated air went into the miner again. Even the room where the warm air went into is much cooler now.

I can vouch for Mark on these brackets. He even talked to me on the phone and was very helpful.  The brackets look good.  Just waiting to get my Titan so that I can install them and see how they do.  Cool stuff Mark!  Thanks!

I've just received my brackets (to France), thanks Mark !

Now, I wait for an order of the tiny heatsinks for the DC/DC converters to begin modifications of my 4 cubes.

I've just moded the first cube with Mark's brackets. It works great and the point with the screws to keep and to reuse is easy to find.

Some pics of my mod : http://imgur.com/a/poykk

Slightly better temp of the ASIC, but the major improvement is the temps of the DC/DC converters. I use the Enzotech BMR-C1 for these.

Feel free to use the pics if you want to do a step by step how-to :)

Bracket kits are still available.

We are seeing about 5 C cooler chip with the bracket application and various heatsinks on the dc/dc bring them down almost 10 C with the stock fan. With a 3000 RPM Noctua fan it lowers everything about a additional 5 C cooler.  Your milage may vary. Please see above posts from other miners that have used the bracket kits.

Thanks.

I'm interested but wow was that a long for sale post...  :D

Im interested too, how hard is it to put the brackets in, gotta titan running offsite that could use some cooling down during the summer months.

I just did my first 4 after stalling (blew a plug..did the dig out the burnt plastic on the plug to the bare pins and slide on the knc y adapter hack trick works well no issues) :)

Anyway got me off my ass to repaste after 22 months

NOTE: they get quite dirty after 22 months don't ya know. (the occasional blast of air into the cube notwithstanding ...) So that scared the living crap out of

me and also helped after cleaning the heat issue. (The rubber mounts they use on the kludge Titan KNC heatsink after time they degrade and  they get oil leak an oil like film that coats everything)

Anyway alcohol and Q tips later ....pain in the butt to clean....ready to repaste

Below is a link to what I think is the best stuff at the best prices to do such a re-paste and upgrade to the X brackets etc on other threads here
also a list of the best parts and prices I could find of the other parts besides Maxumark's X brackets .which at his price is a steal imho.

https://bitcointalk.org/index.php?topic=1283859.msg15286157#msg15286157 (https://bitcointalk.org/index.php?topic=1283859.msg15286157#msg15286157)


Anyway I likely put on too much thermal paste..may as well be up front about this. The thermal paste above is thick above. I've been told
(and 2 of my cubes I got used) that the Arctic Thermal paste is TOO thin ..seemed true enough on 2 cubes I re-did...so I went the other way.
Will become clear below with dithering about it probably did not matter....but that is explained below.

As to the brackets themselves. I had a couple Philip head screws holding the board down on one of my cubes that were NOT long enough to attach the bracket
wings on the existing cooler tube plate on the copper radiator/cooler. So I just swapped them for 2 case cover screws that worked instead and then those Philip head
screws are used now instead to replace and hold the cube cover on. The other 3 cubes the screws all were the same as the titan cover screws etc

So anyway you mount the brackets as per instructions (big whoop ...screw them on with 4 screws).

HOW I did the repaste seemed to work with the thermal paste I list above I used. I put the paste on the cooler end not the chip first....then I lowered it on
to the chip. I then took it off. Sure enough all the edges missed. (note on all knc cubes NONE of the edges had thermal paste on them thus my method and
test above to see first before committing to screw down).

So looking at that I do a bit of 'make sure the edges are covered' and 'touch up"

I then put a bit more on the cooler plate copper tubes part to replace what was taken off in my 'look see' above test (probably I used too much thermal paste
but it seems fine) and made sure all the chip itself was covered along with again my replacement on the cooler plate side also from what was taken off on the
test mount of the above....again getting off as much excess as I could keeping both covered.

I then put the whole thing on the chip. A bit of wiggle and alignment so the screw holes match up and should be set.

I put 2 screws in on on / part of the X plate (cross ways placement of screws) and then the other two on the other \ of the
X plate bracket arrangement. Then carefully went clockwise around not tightening it down too much.

If you look thru at the board below edgewise you can tell if it is 'taco'd' bent a bit much (a bow) so I just release some screw pressure in the above cross X pattern till it all evens out and seems less so and level.

It sounds here harder then what it is..to do the above ...but his is 'just so' kinda fiddling...but when it is all even and the cooler tower does not wiggle at all you are golden!

You should also when you look at the chip edgewise have a nice caulk like bead of thermal paste around your chip
when you look at it from the side. Mine all looked pretty clean in a caulk gun kinda way. I assume the wiggle
to get everything just so works it all around and evens out my repaste (of likely too much thermal paste) with any excess forming this nice bead around the chip :)

Hell whatever floats the boat and works. I've done 4 cubes so far this way they all have the same bead and work great ..just gonna go with it :)

With this mod the clunky KNC with the rubber mount heatsinks are now gone (yea! no more rubber mounts leaking oil)...NOTE: thou I did leave the 2 UNDER the board
rubber mounts alone for support after wiping them down with alcohol and cleaning them ...just so you know)

Anyway with that gone you can NOW see thru the whole titan cube. It is wide open in comparison!

With the chips having heat sinks on them it is quite the little 'wind tunnel' especially with the 3000 rpm fan I used (see above) the fan is a BIT louder but imho maybe only 20% louder) hardly a big deal with my miners in the basement. But man you put that new fan in a cube and do a side by side comparison  of a knc fan in a cube the diff is dramatic
...feels like a hair dryer.....zoom zoom..with the opening up of all that area in there by getting rid of the knc kludge heatsink setup and all them small heatsinks in the wind as it were.

I found 10c temp drop on ALL DIES on the 4 cubes I've done so far. Some up to 15c down so went from 80/70 ranges to the 70/60 ranges and that was the day my
basement was 84F!

Now most of this is this 3000 rpm fan imho (no frigging way was the knc fan as I was told 2000 rpm) but anyway  the clear view and no obstructions
by adding Maxumark's X brackets.....again for a nice wind tunnel effect...all my spiky copper 8 heatsink replacements have no obstructions at all to the fan air flow.

Also of the 4 problem dies that were underclocked on my 4 cubes. And the one cube that could never get above 300 setting on adv page no matter what.

Now after all this the 4 dies that were at 200,225, 250, 275 are all 325. The cube that was only able to do a 300 setting now can do 325 w/o issue BUT was pulling 42 amps to do
so per die ...so backed it off to 300 too be safe (probably will back all my stuff off to 300 as I repaste and clean too keep lightfoot happy.....he is not big on my 325mh Titan abuse)

On the other hand...

The cube that was full out at 325 (and melted the plug and now has the knc y adapter to bare pin hack) is kinda hard to clock down. In that it is at 38/40 current draw
on the dies and in the 84F basement 68/58 for temp on the dies. (lol) So I've left that one alone. :)

I also gained on the tweaks of the above in getting some speed back gained 10mh, thou to be truthful they were plenty oily and dirty let me tell you. I won't let it get
that bad again. Again that is 10mh total for the 4 cubes I've done so far as a total of all 4 not per cube.

All in all with the above items/X bracket/heatsinks/repaste and the gen tarkin 3rd party firmware we just might keep these puppies from going doorstop for another
couple of years (LTC price rise willing) who'd a thunk it :)

Anyway GET THE BRACKETS/HEATSINKS/FAN/THERMAL PASTE and re-do the works and CLEAN the oil/dirt out of your cubes!

They will be oily and dirty even if you have blown out the dust once in awhile. The nature of those rubber mounts after all this time they will have leaked an oil coating
 on everything, dusty thou it may be also.

So I have 10 more cubes to have done. The above cost of all this was 60 bucks a cube (see above links) but man well worth it at these LTC prices etc.

Anyway how the brackets should have been designed (and hell probably were at one time till they went cheap or why the hell are there 4 mount holes in an X pattern
that fits the standard model water cooler pad (see above link)????

So imho KNC went on the cheap and did the rubber foam/plate arrangement to save money on copper
heatsinks per 8 and not bothering  to figuring out a better bracket) (knc: cheap as hell and proud of it) (tm knc)

anyway my experiences with this repaste of cubes and brackets. So I recommend the brackets as a great buy for the price.


Note:  I will add pictures on some of my other re-pastes and this bracket. I just was having so much fun ramping them up did not do so with the first 4 cubes :)

For those interested in another Maxumark mod....I've taken it a step further and put the dual 2560w Server PSU's into a KNC Jupiter Case making it somewhat
luggable/portable kinda sorta.

Anyway here is the link to my imgur pictures on the step by step and the thread started on such.

blurb below

Here is the link I promised on how to make a dual 2560w psu for 300 bucks using a knc titan case (or just zip tie it alone) for 300 bucks or so. About the same price
as one new Corsair 1200i psu. Works slick. Twice the power and same platinum rating.

Just look at the thread below and use the links to follow the pictures. Pretty much plug play and tie down with zip ties no matter how you mount the stuff. Used
electrical crimp blunts for the ends with 15 gauge wire also. My thanks to Maxumark for this idea and the backplate mods. I also have
no other fans on this but what you see. No heat issues at all.

Thread below I started for those looking for a bit of overkill for their A4 Dominators (heck you could probably run 2 of them easy on this setup) :)

https://bitcointalk.org/index.php?topic=1545455.msg15533861#msg15533861 (https://bitcointalk.org/index.php?topic=1545455.msg15533861#msg15533861)

enjoy!


Anyway another Maxumark hack for all :)

more info and temp drop pics to show the improvement of cleaning your cubes and the results of the X bracket mod with all the other bells and whistles and repasting.

pretty dramatic see the pics

blurb below

https://bitcointalk.org/index.php?topic=1283859.msg15544737#msg15544737

shows the temp drops of 15c to 20c on dc/dc's

anyway check out further info there

but man clean your cubes and get the X brackets here  and repaste. Esp get the copper heatsinks and the frigging 3000 rpm fan.

With the mod I also brought back all my toggled down dies that were not shot (off) ...to full out 325 setting on Adv page. I figured at these low a temps
for the dc/dc's Gen Tarkins software would give me a hint by toggling them down IF I'd pushed them too much in my 84F basement with the Titans running.

So far no issues

anyway made a huge diff to me thou with the throttled down dies now back to full out I gained 35mh total. Went from 700mh to 735mh ...thou to be fair
it was mostly due to cleaning my cubes.

Anyway my results. The end result.

Stuck between buying these, and selling my Titans.  Dude, these are really nice.  My Titans are already running pretty cool, but these are very tempting.

Not sure but I'm making $$$ on my Titans with some at 14.6c kwh ....will be like 11c kwh in middle of Oct and I can heat my house with them again (last year 3000 watts plus
this year 6000 watts plus)

anyway why sell....many times tempted ..many times BTC and LTC price have gone up and saved my ass. I mine LTC and put about all but 10% to BTC from my LTC when
the ratio works.

Anyway just wondering..thou I did see this on ebay a cube ..fully working supposedly going for 1000 usd ...go figure maybe I should sell a few of my 1/2 working stable cubes?

http://www.ebay.com/itm/KNC-Titan-Miner-Single-cube-/262560583818?hash=item3d21d4908a%3Ag%3A7gkAAOSw-4BXZvNP&nma=true&si=WGhHZ96MGNTakkWIOf7fnBftk9s%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557 (http://www.ebay.com/itm/KNC-Titan-Miner-Single-cube-/262560583818?hash=item3d21d4908a%3Ag%3A7gkAAOSw-4BXZvNP&nma=true&si=WGhHZ96MGNTakkWIOf7fnBftk9s%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557)


Hmmm..looking at the above I should probably sell my crap too...then again would miss out on free heat this winter (last year at 3000 watts plus heated 85% of the house in winter)

anyway

I'm amazed at how well the Titans are holding their value.  Between my gear for folding and my SHA-256 gear, I've seen exponential depreciation with most hardware.  Not scrypt gear though. 

Anyway, I aint going to complain!

If you have a titan and use this X bracket to open up some air flow.....repaste with the gelin(sp?) extreme thermal paste/ get the Noturua 3000 rpm fan/ get them nice copper
heatsinks for the dc/dc's you SHOULD be able to run these for another 22 months and of course lightfoot here on bitcoin talk can fix them and the gen tarkin 3rd party firmware can regulate them heat wise etc....so hell it is great..main thing on above mods is my unit went from 700mh to 735mh solid on repaste etc above and my die temps went down 10c to 15c so
when I checked in my 84F basement all the dies were running cooler then last winter when my basement was at 60F lol

It is the tricks we have learned and the 3rd party support..but getting rid of that kludge of a knc heatsink and using individual heatsinks for the dc/dc's and the 3000 rpm fan with
the X bracket here...man 10c to 15c drop after all this (about 60 bucks a cube if you count 3 bucks a cube toward paste that is) well worth it

more stable no hassles and of course the thermal paste I had to scrape off after 22 months .(not a good sign) so there is that if you've got them used or run them a bit (that would
be all titans imho that need to be repasted at least asap...so as long as you are at it go full hog above is my advice)

As to why Titans and scrypt has lasted....no one has made anything bigger and at least for LTC more share of network as other stuff drops off the other end

The A4's coming out in 2 months at 280mh and 1000 watts may even HELP the Titans imho and scrypt coin and LTC price..in that it will show that scrypt is not dead and new
equip is being made for it again...considering the above is equiv in efficiency to a 325mh Titan running at 1250 we will have no issues

(unless they sell them like Toasters etc..which is possible)

So yeah the 3rd party support/firmware/being able to fix them is huge......my stuff should be good for another 2 years the new stuff I have will be modded right away to this norm

sometimes it pays to be lucky.....I sure needed it ...mining at 1.30 LTC price all of 2015 or whatever and praying for 4 buck coin and then moved like 8k of LTC

sometimes it pays to be lucky/clueless and stubborn )


But I'm shouting this from the mountain tops...get these X brackets I mean they are 10 bucks for crying out loud. Do the mods etc...if for no other reason for peace of mind in
the 10c to 15c temp decrease......and of course get the 3rd party gen tarkin firmware that as far as I am concerned is 'magic'

The only way to go from now on imho ...and I guess we pray for a BTC (Mario) to LTC (Yoshi) price pump to pull them along a bit easier come Winter when I heat my house again
for free lol :)

I just picked up the brackets from the fab shop today, and already shipped a few orders.
PM me if you are ready to get yours.

Thanks,

Max

More Brackets from the Fab shop next week. Now with the Board Taco preventer included at no extra charge!

Thanks,


Max

Yippie Skippie...you finally got 30 posts....no longer a newbie!  I think you are allowed to post pics now :)

Have you gotten your new brackets in? I'd like to buy 6 of them.

Send him a PM I know he has more in. He even tosses in his 'taco board support' thingy at no cost :)

Yes, plenty in stock. I sent a PM.

Thnms, looking forward to upgrading the Titan a bit. Good old work horse deserves it, especially after it decided to resurrect a dead end of it's own volition a few weeks ago.

**New Difficulty Special***

Free Shipping in the US on all orders of 4 or more bracket kits!

I also have heatsink kits available for $8 per cube with the purchase of Bracket Kit.

Thanks!

Can you explain the taco board support? I ordered brackets awhile ago, before you offered this.

New lower quantity pricing!

DC/DC Heatsinks available also for $1 each or $8 per Cube.

PM if interested.

I'm also interested in all the brackets and heat sinks required for 4 Titan cubes.
I'm in UK.

are you still selling these bracket kits ?

Yes, Still selling these.
Works on Titan and Neptune cubes.
