[PRICE REDUCED] DPS-2000BB 2000W Server PSU Interface Board

[zulover]

Ive gone for these http://www.overclockers.co.uk/showproduct.php?prodid=FG-038-SV&groupid=701&catid=2331&subcat=819

2 for each psu, should be ok.

Running fans straight off the screw terminals is fine so long as they're standard 12V fans.

Our test setup used a pair of high-CFM 80mm fans and kept the supply comfortable at 2500W output.

[Ninetoe]

ordered myself some of these : http://www.ebay.com/itm/IBM-x3250-Server-Fan-Delta-TFB0412EHN-4K29-/360870345147?pt=UK_Computing_Case_Fans&hash=item54058c79bb

should do the trick i would think

Couldn't tell the CFM from the listing.  As long as you're north of minimum 15CFM, 20+ would be better, two of them should work.  Three would be ideal and cover all the spots you need to cover.

26CFM

26CFM

Those'll work fine.  I think my masscool"s are about 20.

So, an update on my fan setup (without pics, maybe tomorrow).  I was able to get 3 x 60mm fans tied together and then zip tied to the side of the PSU, and have them powered directly by the breakout board terminal screws (I don't care about fan speed, I want them running at full speed, screw the noise).  I have them so the airflow is facing outward, meaning the outside air is sucked through the PSU, instead of trying to push the air through it.  Seems to work very well so far, the PSU is noticeably cooler than previously with either 2 x 80mm or 2 x 60mm fans.

Would'nt it be bether/more efficient to place the fan's ON TOP of the PSU ??
Of course, one would have to cut some holes into the metal cover ....

But I think for cooling it would be more efficient.

You could try.

I also thought about that option but the heatsinks are positioned for airflow from the side.

[Atomar]

Those would fit perfect since the case of the PSU is 105mm: http://www.ebay.de/itm/Arctic-Cooling-Arctic-F9-92mm-PC-Computer-Gehauselufter-1800rpm-43cfm-/360945537772?pt=DE_Computing_Geh%C3%A4usel%C3%BCfter&hash=item540a07d2ec

Does the 3 Pin connector work with the board ?

[y_boonstra]

yes that will work

[kgb2mining]

So, will this work with a DPS-1600BB?  Pinouts look the same, and since I'm running only 4 Ants per PSU I'd be fine within the wattage requirements.

 just got the boards a couple of days ago and had 4 psu's waiting which I got of ebay now 2 of the psu popped yesterday don't know why the boats are ok as use the remaining psu and seems to be running ok I have 2 of the following fans on each psu http://www.overclockers.co.uk/showproduct.php?prodid=FG-038-SV&groupid=701&catid=2331&subcat=819

had 6 ants on each psu , what could be the problem?

Probably not enough CFM. These PSUs can be really heat touchy.

I had three identical setups of 5x AM Tubes across 2x DPS2K. On each I put a lightweight 120mm fan (12V 0.5A 3-wire) and a sturdy 120mm fan (12V 3.3A 4-wire) to keep them cool. Two of the setups are running fine on probably around 60% speed on the sturdy fan. The third setup, one PSU kept cutting out even with two sturdy fans at 100% so I junked it and swapped in a fresh PSU, which has been performing beautifully.

Used equipment has varying tolerances on what it can handle, I guess.

yes used equipment is used equipment but 2 in a matter of days I thought I might be doing something wrong, they do get hot I think it must be the fans they are just not up to the job,  I didnt know the board comes with the pwm fan pins. The fans I used seemed slow to me I will have to change them I reckon even though it said a minimum of 25cfm on their description but for 3quid what should I expect.

[kgb2mining]

I had one PSU keep popping off , and I only run 4 Ants on any of them.  Felt really hot - it was cooled at the time with 2x80mm fans.  Swapped those out for 3x60mm fans, configured to pull air out, instead of trying to force air through.  Been running like a rock ever since.

I've had extremely good luck with the 3x60mm fans configuration, and would recommend you try that.  If you want to render your fans useless later on, you can clip the connector end off of it and put the wires directly onto the breakout board terminals (as long as fans are 12v), instead of worrying about the headers off the board.  I can snap pics tomorrow if you want.

ok , i had the fans blowing in towards the psu. ive been looking at he 60mm there are some high speed ones at 4500rpm, im going to give it a go i think and do your suction technique, i snipped the current fans also as 2 wouldnt fit in the pwm pins.

on what side of the psu did you put the fans to pull out ?

ill soon be recieving my high cfm 40mm fans and would like to try the air pull method

If you are looking at the PSU with breakout board to your chest, the right side.

I'll snap a pic or two today.

here is my setup (top psu still missing 4 antminers on the way)

5 antminer running OC 250 seem to be drawing about 2050watt from the wall.

also the fans im using, on pull instead of push worked miracles, i run them at half speed and the psu is not warm to the touch anymore.
the type i used is a few posts back.

ty for the fan tips kgb2mining

[kgb2mining]

Ninetoe - those look really good!  And you're welcome, I'm happy it's working the same way for someone else... you never know when you make a suggestion if it's gonna work for someone or if it fails and you look like an idiot...

I promised pics of mine with the new fan setup, so see below.  I am also going to make a second post about the breakout board holder, as I got my shipment in and have a few comments.

I'll also confirm power draw.  With my "cube" setup of 4 Ants per PSU, I am able to get 4 cubes per 30A 240v circuit to run reliably and cool.  This allows me to get max density of 32 Ants per standard 19" rack cabinet, with only 2 circuits per cabinet.  And, the S1's are overclocked to 393/400 as well so it's still able to hold just fine.

Here's a finished "cube" with the fans on the right side, set to pull air through:

[Ninetoe]

are you overclocking your antminers ?

maybe im pushing the PSU too hard running it at 2000watt constantly.
