The UD3R's are good, I have a nice mix of Rev 1.0's and 2.0's. Both work nicely. I ran overclocked 920's at 4.0GHz on some 1.0's for over 4 months without touching them, restarting or crashes and those 920's drew a lot of power.
man, just go to wal-mart and hack up a box fan. it won't generate much pressure, but it'll provide enough cooling for you to add more rigs.Quote:

trn, you should probably ditch these guys and cancel your order.
Why not try a car rad fan for your car rads? :p:
Massive CFM and you'll only have to buy 2. Quieter too (not like it really matters, but you may have to poke around in there a lot, might as well not have it be deafening.)

Most car fans respond well to rheostat-based voltage control, too.
wow those fans are 63 bucks apiece?!?! and non-cancellable?? that's just wrong. what about some of these 250mm fans: http://www.newegg.com/Product/Produc...e=&srchInDesc=
the static pressure may not be great but they move air for less money
My first fan attempt was with low-cost car radiator fans just like some shown on that site; I bought mine off flea-bay. I had terrible results, the fans were loud as could be, unbalanced and just low quality. The biggest problem with them was that they would draw ~90W and would not under volt. I temporarily rigged them to a ~600W PSU and ran them all off of one fan controller :rofl: (for a very very short time.) I'm suprised I didn't kill the fan controller; I thought it was going to be a sucide run for my lamptron FC-6 or even the PSU, I had a fire-extinguisher sitting by ready to go for that test :ROTF:Quote:

I'm planning for the long term. I feel like i'm getting fans that will work well for my needs for the next 2+ years until I need to rebuild or whatever. Static pressure is also very important for my build because I need draw fresh air into my garage then force it through the rads and out the window. 6 x 660CFM = 3,960CFM which should be good for my needs too. While I haven't bothered with measuring the cubic footage of my 2 car garage that should be good enough to turn over the air every 60 - 90 seconds and keep the garage from building up heat.
These fans also run at 120v and 26W a piece which is great because I can run them off a single UPS or powerstrip and not have to worry about over-loading any PSU lines etc. Wattage wise my WC loop should run:
6 x 26 = 156W (fans)
5 x 24 = 120W (mcp655's)
60W (Taco 1/35th HP pump)
or 336W total.
I should be able to get a good UPS to keep the loop up and running through brownouts and Power outages of a few minutes. Long term reliability and stability is a goal of mine. Some times I travel for extended periods of time so I need to keep everything up and running and somewhat redundant.
And also as a Public Service Announcement:
DON'T EVER BUY THIS :banana::banana::banana::banana: GEIL RAM!!
http://www.newegg.com/Product/Produc...82E16820144266
Two of my crunchers that I was able to get it running with are instable as can be, they crash and reboot through the day. I can't even make that ram run at stock settings on some rigs!
Time to get FCC to step in:down:Quote:

hh, that look like these SEM photos..:),
you got some 5 pins to the right another one that seems short, and that left bottom one seems all screwed up, yet mobo's usually post with a broken pin or 2, no issue, maybe it depends which exactly one,
i would have tried to contact the dealer, that isn't fair, 150$ for an unusable mobo, he said it was bent not dead..
oh, and these 360W for the entire water loop fans and all is quite all right!
Good point. Anything can happen on eBay..Quote:

Just give it a shot and talk to the seller.:up:
You guys are right; i'm giving it a shot with the EBay seller and hoping for the best :up:
Make your message as power as it can be, it will intimidate the seller a bit.:D
Too late, I whined and cried like a wimp :rofl:
That works too :ROTF:
Any updates? :D
Unfortunately nothing very update worth :rolleyes: In other news:Quote:

I've gotten a lot more computers up and running recently; my dining room has been completely borg'd.
I decided to build one dualie with two L5640's in an Asus z8pe-d12 that I bought open box from newegg for a good deal. It won't overclock but I figure i'll stick two of the more problematic L5640's that I have in it and run it at stock clocks and probably not even in the farm. I think i'll build it out eventually as a linux desktop machine/cruncher with a... case :eek: and everything. I'm expecting it won't work with the 32nm 5600's xeons out of the box and expecting to have to take apart my dual E5520 (same mobo acctually) to update the bios with those chips. Should be good for ~8500-9000 boinc ppd. Not putting this in the farm will also free up more space for more rigs in the farm (which its looking like I'll need to get a steady 100,000ppd, if I build everything I have now I think i'll be falling a little short in the 95,000 ppd range.) Another gulfie... or maybe something different like a SB might be a good final piece later to complete my goal... I'll have to think about this.
If i'm lucky my fans will be arriving next week (they are on a boat from england :ROTF:) then I can get on with the real building.
"On a boat from England" ? "Oh, sorry sir, what voltage did you want then? :ROTF:
I just want them in a "working" and "here quickly" voltage :D Its a bit odd why a Chinese manufacturer would have a stock of 110v fans in stock in England:shrug: I guess thats why they didn't sell out on that side of the pond :ROTF:Quote:

*edit for some boincview p0rn*
My current home setup is 14 hexacores; L5640's, 970s, and 980x's. In addition I also part time crunch with my dual Gainstown rig at my office. 6 Linux rigs and 8 windows 7 and Sever 08 rigs.

:rocker::woot::hump:
After too long I finally get to post a worthy update :rocker:
My Fans:
Their trek started at a Buddhist monistairy atop a 15,000 foot Himalayan peak where Buddhist monks hand crafted each fan per my order, the fans then traveled by Yak through some of the most treacherous roads in the world dating back to the age of the Silk Roads down to India. Once in India crooked custom officials had to be payed off; fans loaded on a WWI to make their Indiana Jones red-dash style journey Europe! But oh no! the ship was hijacked by Somalian pirates! Have no fear the Navy Seals showed up and guns blazing saved the day... The ship made it safely to England where they were lorried to Heathrow to be aired to the US but the package got lost in the freight terminal for a week. Volcanic ash from an icelandic volcano named Eujagonnafukwitualljokull grounded all flights (not sure why this wasn't on the news :shrug:) Newark now realizing they might not meet their promised "orders delivered within 14 days" jumped into action and called in a favor from Sir Richard Branson who strapped the fans to the side of his hot air balloon and fired them up to full power and personally delivered them via Virgin Gallactic Hot Ballon to my door step today!! (this made the local news, should be on at 11pm!) So a big huge sarcastic :up::up::up::up: for Newark's prompt shipping and awesome customer service! I would personally recommend using them to anyone who loves to wait over 6 weeks for an in-stock product to be delivered!!
Comparison shot with a 120mm S-Flex; the Sunon is a 254mm (10") fan:
http://i399.photobucket.com/albums/p...ct/sizing1.jpg
And here's the real money shot, 3.5" of depth for awesome-sucking static power; Girth and Length!
http://i399.photobucket.com/albums/p...ct/sizing2.jpg
Test Run on my counter, the fans run at 120v and use only 26w which is nice and push 660CFM at a moderately noise 50db. This picture looks like a random object search; find the bananas, sun glasses, pliers, passport for bonus points!
http://i399.photobucket.com/albums/p...ct/TestRun.jpg
This shot is for OneX who has called me out on not properly insulating my boards from the rack TWICE! I put 1' sections of PVC piping under the boards and zip-tied them down to the racks. Less than a dollar per board and I still get good airflow to keep the back plate cool.
http://i399.photobucket.com/albums/p...insulation.jpg
My Cheapo Home Despot clear vinyl tubing has turned brown as can be. Coolant is distilled water and PTnuke. The water is fine but it now looks like I have a farm cooled by diarrhea.
http://i399.photobucket.com/albums/p...brownhoses.jpg
Some quick work with the saws and I rigged up 4 of the 6 fans for a temporary mounting solution. Each fan weighs around nine pounds, nothing is holding them in place now but they are well balanced so it should be good enough for a while until I finish everything up later. The fans work awesome, they are sucking and blowing nicely :)
http://i399.photobucket.com/albums/p...ct/action1.jpg
http://i399.photobucket.com/albums/p...ct/action2.jpg
Here's what I currently have been running on the diarrhea cooled system for a few weeks. Two 970's and four L5640's. I have six L5640's on air and one 980x on air that have borgged my house and are waiting to be put out to pasture in the farm. Some of those are not overclocked or have a minimal overclock so I can get more performance from most of those rigs under water.
http://i399.photobucket.com/albums/p...t/IMG_1046.jpg
This should be the coup d'état for my goal of 100,000ppd average. A dualie, which I will put my last two L5640's that have been paperweights on my table for to long. It won't overclock but i'm going to run it stock :eek: and eventually even put it in a case and turn it into a Linux workstation to screw around with and load it up with a raid 5 array for network storage.
http://i399.photobucket.com/albums/p...ect/dualie.jpg
And for a closer, here is the current result. Temps dropped a lot and so far zero heat build up in the garage (look at the old real temp max temps.) Gotta start working on getting everything under diarr.... uh I mean H20 before Supercomputer Week!
