Niceeeeeee.

Yeah nothing beat a clean looking install, nothing more satisfying  

Lol, i can't imagine the looks on you when electricity goes out   But you seems to have been pretty careful so i highly doubt it's your fault, now to explain it, that's another matter  

Those PSU's look awesome, what are their specs/price/model ?

It's best to reach out to Finksy who is a senior forum member as prices do change.  However he's very good at keeping cost low.  The PSU is made of 2 x 2KW IBM Server PSU and are combined using a breakout board that have 30 PCI connections.  Finksy also sell a custom FAN mount to help tighten the connection between the PSU together as well as mount your fans.  They become a 4000W PSU that are very beastly and can take on any GPU rigs you can throw at it.  They do require baby PSU to power the power risers and Motherboard / SSD.  However he just teased me with this PCI powered riser and a Pico ATX Psu option to allow straight up server PSU power config only as well.

Riser Teaser - Pico teaser to follow soon.


So I was looking to buy over 150 fans to cool my server case rigs as well as my IBM server PSU.  Previously my go to fan has always been the Ultra Kaze 3000.  I end up ordering hundreds of dollars worth of these fans, just to hear from Finksy and Hawkfish007 saying " NHAN, I got these FANs, you must check out!!!"  They both send me a bunch to review.  I must say, I will never go back to Ultra Kaze again.  The Ultra Kaze are great fans but they are not ball bearing and typically cost $15+ each which adds up fast when you need 150-200 of them.


Hawkfish007 Fan

FAN in the middle


These fans are ball bearing so in theory should last longer than the Kaze but time will tell.  I really like them and they're about the same wattage as the Kaze but feels about 10-15% stronger.  Prices are super cheap compare to Kaze and these are good for 90% of the purpose needs for sure.  If you're interested Ping Hawkfish007

Finksy Fan
Finsy / Taylor send me some of these to play with.  They are absolutely beast! OMG!!!!  They are a little more wattage and louder at startup but it's a nice sound unlike the screetching Antminer fan sounds.  These definitely can cool S7 and S9 with ease. They will also be great for the IBM server PSU.  They are louder so best to use in garage or hosting facilty but again it's a nice loud white noise sound not nasty Screetching sound.  It's the sound of "FEEL MY POWER!!!"  I'll let the picture speak for itself.  The white material is the TARP I use for my portable wall.  Notice how it becomes a Sail when hit with 3 of these Fans?  





You simply can't go wrong with either of these fans.  They are so awesome, wish I found them back in the S7 days.

the one the far right is  scythe

 https://www.amazon.com/Scythe-DFS123812H-3000-Ultra-Kaze-120mm/dp/B001JKNMBE/ref=sr_1_1?ie=UTF8&qid=1486688081&sr=8-1&keywords=scythe++fan++120+x+38

[yun9999]

Other than the Scythe fan, the other 2 you have to buy thru a reseller which is either Hawkfish007 or Finksy.  You can PM them for more info.

[Zimmsquad]

Were the resold ones cheaper than the scythe ones or is there a place to buy the scythe ones in bulk for a discount?

[yun9999]

The other ones are still cheaper to buy then bulk discount with scythe.  Even if they are the same price, once you try the fans, I think you'll be more impress with them.  All 3 are great but I dont' think the Scythe deserve the cost premium.  The bulk discount usually requires high volume else the discount isn't too much for Scythe.   For the other 2 fans, they are design for volume so it's easier to negotiate volume discounts.   I had to haggle a lot for my Scythe and in the end they tried to raised the price after we agreed, so I got pissed off and canceled.  I end up paying more from another vendor but I was ok with that as I hate shady business practices of bait and switch.   It goes back to my convention of if I can buy from the same quality vendor, I will always do that.  If I can do that AND it's from a FORUM member and I can help our community, that is GOLD.  Needless to say I'll only be buying my fans from either Finksy or Hawkfish going forward.  

[Zimmsquad]

Sweet, thanks for the info.

Looks like I'll have to hit one of them up for some fans

[Finksy]

Hey Nhan! Sorry it took me so long to jump in here and congratulate you like everyone else.  I'm just so used to sending you desperate S.O.S. messages about my own crap that I never look you up on the forums    Your never-ending drive to improve your mine (No, it is no longer just a home) may border on addiction, but it is absolutely inspiring.  Every time I think I have a good idea, you are always 3 steps ahead of me    One of these days I'll catch you off guard!  Until then, I'll just keep taking in the scenery.

Anyways thank you for the shout-outs, it's much appreciated.  Nhan is by far one of the most hardworking, helpful, patient and generous people I have the pleasure of calling a friend. He might only surpassed in patience by his own family.  He's the reason I'm getting more involved in the GPU scene these days, and like he alluded to I am about 99% done getting components together to offer full GPU rig packages by server PSU's.  I am just finishing up some testing right now and have a few more custom cables on order.  I am currently helping a customer deploy over 700 GPU's in a DC, so it will be a good large-scale test-bed for the DPS-4K to power the rigs without the use of baby ATX PSU's.  

As for the products I have, the DPS-4K PSU's can be found in the link in my signature.  I will be starting a new thread strictly for GPU rig powering and the bits required for it, should have everything together in about a month once my customer has everything off the ground.  Those 120mm fans Nhan is testing can be found in the DPS-4K thread as well, I now include them with the PSU packages I offer.  I could have (and if it were up to Nhan I should have!) gone with a lower powered fan. But I wanted to stick with one type and offer something that could be used for cooling full server chassis, used as a replacement fan for S7/S9's (probably require some underclocking though), cooling the 4K PSU's in ANY environment and under ANY amount of load, etc.  I prefer over-doing it, even at the expense of more power consumption.

Anyways, thanks again Nhan.  Once I have everything in hand I'll be sending another care package your way so you can see for yourself how nice it is to break the dependence on ATX PSU's altogether.

[yun9999]

They are beast.  It takes a lot to impress me but boy 3 of these move some serious air.  For the small extra wattage I think they are definitely worth it as they will definitely work in any environment.   I'm actually using them on my top rigs just to move the air toward the attic exhaust fans better and not recirculate back to the intake side as much.  Please do share more info when you get the Pico working, I'll be first in line.  I have 2 of the 4KW PSU bundle just itching to use it.  Very excited to test with the PCI splitters to allow the 30 connections to become 60 too.  PCI Risers will always be better than that crappy cheap SATA to molex cable that can either melt or come loose and catch on fire.

I'm sure we all have this issue!!  This is why I only buy from Hawkfish007 for risers.  Fast USA 2 days shipping and he stands behind his products.  I've ordered over 200 risers from him hardly have any issues vs the cheaper quality risers where you can literally feel the SATA to molex cable burn your hands.  Those will surely eventually catch on fire.  I've got burned with so many bad risers it's ridiculous so learning from experience, I only stick with reputable vendors and fast speed is critical to us miners as 1 day of idleness = lots of money that can be used on accessories / risers.




On a different topic..............

*******Friends********* - If anyone have good ETH ROM for the MSI 480 RED or Armor 480 that is stable.  What I mean by that is, not a ROM that is just copying mem strap from 1500 downward or  pushing memory beyond 1950 where it's good to use and show off for a 1 GPU setup but is very unstable for a 6-7 GPU rig.  Please PM me.  It's been a while since I been mining Eth on the 480 and my 480 ROM is tailored toward ZEC.  Also Sapphire Nitro RX480 8GB, not sure how I have just 1 of them in my farm.  Maybe a Black Friday special.  Forgot.   Any help there is appreciated as it's been a while and I really barely have sufficient cycles to even finish setting up rigs, so I don't have the tweaking time as I did in the past but I know they can do 27-29MH easily.   Thanks...............

 

[philipma1957]

I have found a good fan controller.

It is a ham radio power supply.  4 to 15 volts. 25 amps constant.

That would help sound levels on all three fans in the thread.

Links to follow.

here is what I have now  $59.95

http://www.ebay.com/itm/JETSTREAM-JTPS14M-12-Volt-4-16V-Variable-12A-14A-Max-Switching-Power-Supply-/192080751641?

just purchased this one for 95  with shipping included

http://www.ebay.com/itm/131536990208?


the jetstream is running 9 stock .8 amp fans in the pandaminer  at 9 volts zero issues.
it could run  2 maybe 3 papndaminers

 the newer stronger psu  an mfj should run up to 5 maybe 6 pandaminers  4 to 15 volts 9 is sweetspot.


these could run lots of finksy's fans

[yun9999]

That actually can be very awesome for a controller to put a few of Finksy Fan in front of my standard 4 ft Rack where I can control the intake fan power base on heat.  Much sexier than Box fans.  =)

[m1n1ngP4d4w4n]

Nice psu & fans recommendation, i will check it out if possible !

I've recently invested into greatly expanding my GPU mining farm.  Yun and Hawkfish007 have helped me a great deal to quickly and efficiently expand to almost 30 rigs.  Hawkfish007 risers and fans are top notch and I wont consider using anything else going forward.  My refresh of my farm should be in order by the weekend and I will update with pictures.  Hope to make Nhan and Hawkfish proud!

[yun9999]

You sure move fast Reelen.  I know you took over 12-14 rigs from a hosting site but building 16-18 rigs in that short of a time is amazing!  Yeah, can't wait to see your Sexy RX480 Nitrox light up.  I believe you also purchased some of those 4KW server bundles as well.  Show off them sexy 4KWs too if you got some pics.  You're definitely Vega 10 ready with those PSU as it wouldn't matter if they are 150W or 350W for each GPU, we're ready!

P.S So many extra rails arrived!!!  Packing 1 box and shipping it to you now for your Sexy Rack.    Back to work I go, on my rails.

[Zimmsquad]

How do you hook up the 4kw psus? Do you use one per few rigs with 7 cards?

[klimpa]

Awsome farm you have there mate. keep up good work.

[yun9999]

How do you hook up the 4kw psus? Do you use one per few rigs with 7 cards?

You connect 1 baby PSU such as a cheap EVGA 650 watt PSU to power the MB and power risers, SSD for each rig.  It's best not to go too cheap on the baby psu as they wont last too long or may not be able to handle the summer heat under max load during the hot summer.  Remember cheap PSU ratings may not be accurate and they tend to post Peak Power vs RMS (continuous use) which is what you want for 24/7 operation.   Finksy is coming up with Pico PSU options as well so it will get more interesting.  I will review it when he send me some.

The GPU gets powered from the 4KW (2KW+2KW) which plug straight into that 4KW breakout board.  The 4KW PSU's breakout board have 30 PCI slots so you can power up to 30 GPU no issues.  I power 5 x 6 GPU rigs 470 and 480 for many months.  Keep it mind that some of the power is being handled by the baby PSU so only about 2/3 is being powered by the server PSU so 30 GPU is no issues for this BEAST of a PSU.  They're server class so they're built like Tanks.  I abuse them non stop for close to 2 years in the Houston heat and humidity for both Bitcoin and GPU mining. I also bought spare 2KW PSU since they are so cheap for backups.   This is why I hardly ever recommend paying $350-450 for a EVGA or Corsair PSU 1500-1600 PSU that at best can handle only power 1 rig but sadly can't even do 7 x R9 390.  I do love my EVGA 1200 Platinum and EVGA 1300 as they are priced reasonably per rig when on sale and they keep their values for many years.  

EVGA is my go to brand as their support is First class, super fast replacement / RMA.  I find their cables more flexible and durable than other brands but that's just my opinion.  I'm not sure if the other EVGAs have the same protection but the EVGA 1300 seem to have a smart trigger where when there's a short somewhere, it will shutdown the GPUs and motherboard.   You can't power it back up unless you reset the MB plug but even then it will turn it off shortly after again.  This gives you the opportunity to fix the issue by disconnecting and reconnecting the GPU 1 by 1 to find which one is causing the issue and replace it.  Once I had this issue and via troubleshooting, swapped to a Corsair PSU  BOOM, one of my RX470 exploded!!!!, The GPU that is causing the short is usually always the one that will end up exploding as I had a few of this incidents.  So when you see this issue, don't blame it on the fact that you're using dual PSU with the IBM server PSU, that's not the reason as you'll also see this in single PSU setup.  All my explosions were from single PSU setup.  The Corsair PSU didn't cause the issue, it just wasn't as smart to know there's a Short.  That was a scary experience.  =)  

I have many MSI RX470 and initally that's a very common issue.  Perhaps that's why they came up with MSI Armor?  To protect you from the explosions?  Haha.  Haven't had 1 explode since so it must have been initial bad batches but my friends have had similar experiences.  It sounds very loud and scary but after you see it once, it's not scary anymore as it's just a small spot that gets burnt, but could also be a capacitor in the inside that we can't see as the sound is like a small bomb exploded.  It won't damage the rest of your rig or cause any fires.  See picture below.



Other than that issue which doesn't seem to happen in later batches, I do like my MSI RED GPUs and hence why I standardized on them.  Not only are the MSI RED the sexiest RX GPUs w the RED LEDs and cool Tiger look, they also have 1 of the best cooling system of all the RX series bar none.   I didn't even have to use box fans for my RX470 rigs even my garage temp was hovering over 100F.  The Twin Frozr system automatic stops the fan when they're below 60C or something like that.  How many GPUs do we see going below those temps?  For the MSI, it is quite often as they run very cool.  So often that I thought my rigs were down.   I'm not as much of a fan with the Armor series.  They took out a lot of stuff to make the price more competitive and it's quite obvious.  No sexy back plate for the RX480, different and cheaper heat sink and fans, etc.  They run much hotter as well.  The Reds are worth the premium.

Wow, thanks for the detailed response!

So, to combine both of your favorites, what about if I used EVGA 650 P2 for the baby ATX and then the 4kw PSUs for 4 rigs with 7 cards each?

Also, I have never used more than 1 PSU before, so is there a special way to turn them on? I am assuming turn on the 4kw before you power on the computer with the baby ATX?

[m1n1ngP4d4w4n]

Are you going to switch to 6x pin powered riser and some other adapters to get rid of the baby PSU ? or do you think you will still one for the motherboard/harddrive ?
