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.

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.

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.

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

I'm using 60mm case fans, server grade with 20+ CFM. However, with only 2 of them the PSU's still get quite hot although they seem to run fine (powering 4 antminers).

Anyone successfully running 3 fans against the PSU? I'd like to add a third but the Y-splitters I got don't seem to work with the pinouts on the board. Is it possible to instead just run the fan wires right off the breakout board screw terminals? Or is that too much voltage that'll fry the fans?

what kind of fans are you guys using ?

i put 2 40mm fans on the side, but they are just normal papst ones, not server grade.

and the psu shuts down when im pulling about 2kwatt, i can feel it getting realy warm, so im assuming the heat is shutting it down.

any tips and links to fans that are being used and works with 2k watt draw would be much apreciated

The fans im using displace almost 24 CFM and they are server grade

Just don't try to plug any hardware up with your cables attached like that.

Pretty nifty setup overall.

Word and yeah,I don't have access to 220v so I can't use it anyways Cool

Just glad I was able to borrow a board and had the $$ to purchase a PSU for product dev.
Going to start on the stacking PSU racks,which will be modular so you can add more PSU's on a single "rack"

Order info can be found here...

Thanks all!

edit: I will be making a trip to the local hardware store with a PSU and case bottom in hand so I can source the proper sized bolts/screws for securing the breakout board case bottoms to the PSU..I thought I had some here but there were either too small or too big, hehe

Alright!
One last minor change to the base and lid then these are ready for production! Super stoked!!!
Here's some pics...

I am already scheming ideas for the 2x PSU modular stackable rack, woohoo!

ps- thanks data55 for loaning me the bb Grin

I hate to bring this to you, but that lid aint gonna work if you use proper wiring:

Meh, simple fix mate! Wink

Printing the latest lid revision now. I've added more clearance for the cables. Pics WITH cables installed soon!

I recieved my breakout board yesterday. Just wanted to share the board and psu setup so far

Look very good! What kind of fan's are you using? Are those loud?
Like to set up my PSU alike.

Thanks

i used these fans:
http://www.ebay.nl/itm/390571240790?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

they move a LOT of air on full speed (more than normal 80mm fans), but can be loud. Before i placed the fands i i removed the mesh of the psu cover behind the fans to get an better airflow (hole of 38mm) then i screwed the fans from the inside.

PICS!

Making necc. changes to the model now to incorporate PSU mounting screw locations, should have more updates in a few hours.

Edit:Now printing the recent changes. I will post back here with fresh pics and more info on the case in a couple hours.

The potentio meter is for the speed adjustment of the fans.
ill keep that one in reach if possible

Awesome and thanks for the reply mate.

Just gotta take pics of the latest print...had some unforeseen circumstances crop up this morning and I was able to get the lid print started a mere 3 hours after I went to bed earlier. Cleaning up my photo studio area and taking pics asap. Once UPS delivers my PSU I can start working on the feet and screw mount locations plus the 2x PSU stacking rack, which I should be able to make modular so you can add more 2x PSU rack units without tools and keep them secure.

Thanks for this pic (and the other)! Very helpful/insightful for my enclosure design. Time to modify the lid so that connector can be plugged into the board without removing the lid.

edit: ZOMG! My PSU just arrived and I attached the encased bb...NO FEET REQUIRED! Plus it won't take long to get the screw holes added. I've already adjusted the lid design to allow the cable/connector to feed through the lid (optional).

Taking pics now!
