Overheating problem with new node
April 6, 2012by Wm. Josiah Erikson (wjens)
It looks like Kwaku accidentally discovered a problem with the new node’s config. It crashed in the middle of him running something on it, and I found it totally unresponsive due to (probably) overheating. I think that 2U just isn’t enough room for this heatsink and fan combo to work with, and also I think that the placement of the memory prevents airflow through the heatsink fins. Clearly the fins should be facing the other direction. I think it will be clear from this pic. Unless I can figure out some way around this, that nixes using these. Perhaps a different heatsink, or maybe even just getting two 8GB memory modules and putting them in the slots further away from the processor?

It looks like a 2x8GB kit is around $100 for 1333Mhz memory… so that’s doable.

Done, reinstalled in rack. Hasn’t overheated in awhile, but that was before I replaced the RAM. The new RAM looks like it’ll block the airflow a lot less, too.

Died again today, looks like actually it was the power supply! It won’t turn on at all now with the old power supply, boots fine with a new one. I shall replace it!

Now it looks like the new RAM is bad… humph.
