Update Large review of Finksy/J4bbrwock server psus compared to ATXpsu-photos up

[kilo17]

I am going to buy the silverstone  ap 182 and use it to show  watts saved and sound level.


@ kilo17  you are going to cost me money


found a review on the fast model:

and found a better usa price. no referral link here it is.

 28 bucks and 10 to ship via usps

It was $32 shipped on Amazon and the price went up to $40 about a week ago.  It is an awesome fan and extremely quiet.

kilo17,

Looks really cool. I wish I waited a few days before ordering a whole bunch of 2000W PSUs and fans.

[kilo17]

I tested it last night and now I am going to make a proper plate to mount the fan.  I didn't want to waste time cutting one out if the fan wouldn't keep it cool.  I did leave a channel between the PSU's by stacking them to aid in cooling although I am not sure if the channel reduces the pressure and limits the flow through the PSU's. 

[philipma1957]

those fans max at 20 watts


the servers max at 60 watts  so 3 are 180 watts

180 watts vs 20 watts  is 4 kwatts a day 120 kwatts a month 1500 kwatts a year

Your investment is safe.  Per S7 wise, the 2000W PSU bundle is still the best bang for the buck with no mods required.  Quiet as a whistle with the Ultra KAZE fans.  The fact that you can add voltage changing abilities is just extra bonus on top.  I may get 1 x 2980 to play with it in the future but most of my purchases are still leaning toward the 4K bundle with the 2x 2KW IBM PSU until the 2980 becomes more affordable.

if you do 6 or 12 or more  s7's

the 2980 with kilo17's mod  is most likely the way to go.

And only if the 2980 gets much better efficiency.

my testing shows the dual 2000 = 4000 is better power use then the 2880watt.

this has been with  2 avalon sixes

one reason for this is the dual 2000  uses 2 .6amp fans total of 24-26 watts

the 2880 uses 3 1.68 amps fans  total of 59-61 watts  .

one runs at   9.2 amps = 0.3247 watts a gh---dual 2000
   the other at  9.3 amps = 0.3282  watts a gh---- 2880

While doing 6800gh

  all estimates from memory.

kilo17's mod is huge for every 6 s-7's using   3 2880watt psu's

you save 150-160 watts 24/7/365   about 150usd  a year

I ORDERED 2 FANS FOR MORE TESTING.

I ALSO think his fan mod will work for the dual 2000.  which is why I ordered 2

Kilo,

love the mod on the 2880W PSU's, that is killer.

Maybe we need a DPS-6K triple-2000W PSU using a single 180MM fan?

Yeah, I think I will like the 2x2000 setup better because of its small footprint. Waiting for Finksy's boards to be delivered in 3-4 days.

I think that could work.

I wondered if a 2x board and a 1x board could position the cables correctly?

I think nhando has the dual and the 1x board on hand .

WoW !

I agree

[philipma1957]

I have two of the high speed fans coming in. Along with a lot of other stuff.

2980 watt

a clamp meter.

a special power cable diy that will allow for reading amps to .01

the two fans and two grills.

I am hoping to run these test and setups by fri or thur.

Did you mod one of the 2880 PSU to run the fan or do you just run the fan on a standard ATX PSU?  I wonder if there are PCIe to 3 pin fan cables.

Thanks, I am telling you it is the most quiet fan for the cfm.  I would love a triple 2000

It is a 2 wire out so I simply spliced it into a PCIe and plugged in it.

NOW THIS IS A GOOD IDEA!  Triple or QUAD 2000PSU with 1 FAN.  Muahhahahah.  DO IT!!  I'm building with many 2K PSU.  If I can stack more than 2 in the same space since I have plenty of height space, it would be a huge space saver!  I'm going to order 1 right now for fun and compare it against 4 x 2KW PSU stackout on top of each other with 4x Ultra KAZE Fans blowing from the side.

See my RACK.  I can easily stack 3-4 x 2KW PSU with this FAN Mod.  It would also be much more efficient cable management wise with the new 4K Board then my single boards which have to be spread side ways and waste too much space.  I put 2 x 2KW PSU combo opposite as they spread too wide sideways so the other other pair of PSU using single boards will be running PCIE from the back to maximize space.  With the 4K boards I have coming next week, I won't have this issue and I can stack 4 PSU on top of each other with no issues and cabling will be much easier and neater.

Please quote so the picture will show.  Please don't mind the 3 fans.  I'm doing Heat stress test and exhaust test with 3000CFM, 7000 CFM Axial fan and 600 CFM Centrifugal.

@Kilo17 - How do I cut /connect the cable or connect for the 182 version that is 3PIN with 1 manual controller for FAN speed?  Or can I just connect this to the 3Pin FAN Controller on Finksy / J4bberwock board?

I would think you just simply connect it to the 3Pin FAN Controller on Finksy / J4bberwock board since you have that board.  The b/o board made for the 2880 / 2980 PSU does not have a 3 or 4 pin fan jack.

As for CFM on exhaust fans, you cannot always trust the CFM declarations made by fan manufacturers.  Especially, if the fan is not inside of a tube axial type enclosure.  I've found the longer (deeper) the tube axial is, the better CFM will be with the same size motor.  

I've had a little bit of experience over the years with exhaust fans for wood/furniture shops when staining, painting, etc...  My father always had a wood/furniture shop built on his property where ever they bought a house.  I also worked in a furniture factory in Berlin, New Hampshire when I got out of the Marine Corp in 1988.  My father and the owner of the furniture factory both said the tube axial design is the way to go if one can afford it and has a proper place to mount it.  The tube axial design has more suction power than one that has a rinky dink box or cage built around it.

Here is a link for example of Tube Axial Fans with the cheapest price.  You will not find cheaper prices on the internet for fans of this quality that are new:  http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR0.TRC0.A0.H0.XTUBE+AXIAL+DUCT+FAN.TRS1&_nkw=TUBE+AXIAL+DUCT+FAN&_sacat=0

Also, if you can afford or find an affordable tube axial fan, it is best to get a belt driven tube axial than a direct drive.  If something should ever go wrong with the motor of a direct drive model, you will have to disconnect the blade from the direct drive motor.  THAT can be a pain in the ass!  If you have an issue with a belt driven motor, you can easily take the belt off the wheel of the motor and do maintenance or replacement much easier without having the frustration of removing a fan blade.

You can tell I'm doing FAN and Exhaust testing from that picture with so many fans eh?  Haha.  In my garage, I'm very limited to options as I don't really want to cut out the walls as the exterior is Brick.  I'm blowing out the Garage door thru the Windeevents, hence the small 600 CFM Centrifugal fan.  That works well but it's too little power to handle a 24x20x10ft Garage which is 7200CFM.  Assuming that the manufacture even does half their rating which makes it 300CFM, that's 25mins per full air exchange.  This is way too long of a time and heat would just build up too much during that time.  This is only ok when the outside temperature is 70 or below but definitely not when temps are in the 70+.  The bigger 7000 CFM which as you stated, are no where close to the manufactured stated output.  Let's assume it's 3500 CFM, is powerful enough to quickly push hot air out on hotter days where I would just raise the garage door up 6-12".  It does the trick but I'm working on running Exhaust thru the attic, it's the least efficient way but it would offer the cleanest looking as my wife does not like keeping the garage door and my garage is street facing so I really shouldn't be adding more than 4 Windeevents where HOA will start knocking on my door.   Those Tube Axial fans are very cool but I would probably only consider them once I start moving out to a warehouse, which may be soon if my Shed / Garage solution draws too much unwanted attention.

P.S I ordered both the big Fan that Kilo used as well as more Ultra Kaze fans to test a 4 PSU stacked configuration.  I think with the new 4K board, I can taped the 4 Ultra kaze fan on or use a  FAN mount to the side and it will plenty of CFM while offering a very clean / sexy look.  But it still doesn't hurt to try that 1 big fan method too as its' cheaper at $40 (170CFM) vs $68 for the 4 Ultra Kaze (130CFM x4 = 520).   These will arrive before Finksy board so I will test them next Monday.

What is a BB board?  Is that a control board?  

Bitmain is selling BB boards, 18 pin (120mm) signal cables, fans, etc...
