High Temps w Dual Xeon 2687w & Mora 3?

post #1 of 4
Thread Starter 
I've been watching my temps more closely than normal the past few days and I've noticed that two of the cores on my second Xeon get up to 118F on normal/light use. The water in my Swiftech pump/reserve combo, only gets up to 31c/88f and is normally at 29-30c/84-86f. I'm worried that somewhere in the loop the heat isn't being properly exchanged, and I don't think it's the waterblock's, because I used, from what I can see, the right about of TIMM (Noctua NT-H1), and tightened them enough, not too much thou. Anyhow, here's a list of the equipment in the loop:

  1. Swiftech Maelstrom 35X2
  2. HEATKILLER CPU Rev 3.0 x2
  3. Watercool MO-RA3 9 x 120mm PRO Extreme Radiator
  4. Corsair SP120 High Performance x6 (soon to be x9)

I cleaned all parts prior to use, and only use distilled water, with a silver kill coil in my res. is it only the six fans on the Mora, will 9 or even more help, is it the water block seating or the TIMM I used or error in the application/spread?

What do the rest of the cores go to? If all cores are very hot, then verify that you have decent water flow. You don't want to fall below 0.5gpm flow rate; most people with CPU and GPU (2 blocks) usually have 0.75gpm to a little over 1gpm when using a D5 or MCP35X depending on restriction.

The CPU die is pretty long, so you may try rotating your block by 90 degrees (to try to match the block bow better) as well as make sure your TIM coverage went all the way to the edges. I assume you used the proper pea/rice grain method and didn't try to spread the paste or anything by hand?

A few degrees cooler than the last two cores. Sometimes a random core will have a higher load, and thus be hotter. And I can't really rotate the waterblocks, due to having to match the inlet/outlet holes. and I applied the paste and then spread, since I didn't have full coverage with the pea method when I only had one Xeon and a Corsair h100i. The heatspreader on the socket 2011 xeon just seems too big for the pea method to work, at least for me.

my flow also looks to be good, as at full speed, my pump sounds like a vacuum, and there is a difference in the level in the tank between the return and pump intake sides at normal speed.

If the pea is too small, then make it a mutated double-sized pea. Spreading the paste is really bad because it causes giant pockets of air to form between the block and CPU, which acts as a heat insulator.
