Counteracting Too Cold - Page 4

Well. . . when I arose this morning I found it labeled as -16F(-26C) outside and the machine was nowhere to be found.

The real disappointment is that it is the third best of the entire farm, with dual 6c/12t Xeons. But, alas, it appears to be a fair weather worker.

To end on a good note (while hoping not to jinx anything), the rest of the shed appears to be performing well.

The temps have been fluctuating as low as -20(F) and up into the 40's(F) and so far I've found a workable solution:

- I removed the main case fan. I actually found one of its fins in the bottom of the case, so it will need replacing, anyway.
- I closed the main holes, such as drive bays.
- I left the power supply fan alone, although it may be big enough to supply sufficient air flow for the "three weeks" of summer.
- I tasked 8 threads to factordb "elf" duty on a 24/7 schedule, using only the remaining 16 for main factoring work (ecmpi and CADO-NFS server/client).

It's been a little over a month with this setup and I'm hopeful it will keep plugging along.

Thanks for all the ideas.
