How many rads to cool 2 Nehalem chips 24/7

niko084 · Nov 25, 2009

They will be doing 24/7 floating point calculations, so expect 100% usage.
I want to keep them cool, cooler than the bloody stock heatsinks.

On another note, not having used these chips before, do they use their own crazy bolt through heatsinks, or snap downs like their standard i7 counterparts?

I was figuring at least a triple if not dual triple 120mm rads would be needed.

Try a MORA, i think thats the name.

One MO-RA 2 will cool them both. It's a 9x120mm radiator. They have crappy push pin coolers.

Two 240's will do it very well, and the chipsets/video/REGS

Pump, Chipset/regs/radiator/CPU/Video/Radiator/CPU/Res

I want to redo my loop when my next video card is ready. Add in a split off two 3/8 and cool my chipsets.

One 360 triple core is enough that I don't see much variance in any temp with 1/2 tubing.

If they're stock, yes, if they're overclocked... no

Can't be overclocked... After thinking about it more, I may just hang some big air coolers on them.

It's going into a Silverstone Raven.. I am going to have to let this run WCG for a weekend before pickup!

Thanks for the replies, my head is spinning here trying to keep track of what I'm doing.

Which Xeons are you using? Doesn't take much to cool the 80w/95w models.

And yes, they use heatsink that screws directly into the motherboard tray of a compatible case or plates can use used. Some boards come with them, some heatsinks as well. I don't know if a push-pin heatsink is compatible or not.

The W5590 3.33ghz the 130W versions.

After looking, the board has some screw down plates, but I have seen pictures of people running standard desktop level coolers on them.

Unless someone releases a board with overclocking ability for dual 1336s I think they will get the SD964 Xig, being it's going into a Silverstone Raven it shouldn't have any issues staying cool. But I did want to know on the water because he would prefer to clock them, and in that case I would prefer to just setup a loop for it and be done, when the software is compatible with Cuda we will also be adding in 4 cards and it might be upgraded to the i9's at release time.

One 240cm rad each should be more than enough

a good 480 rad would suffice. more is always better though.
