Re: Relationship between WU and CPU?

I was wondering if each WU requires different effort from the CPU, thus causing such temp variations? Are future WUs likely to show such variations? Naturally, I'm pleased that the temps have dropped a few degrees, as it was my intention to move a couple of the Antec fans to the high setting (all are on medium) at the weekend.
Trying to help get it on the right track again...Iain.

I don't know about WU giving differing stresses on the CPU to give differing temperatures. That said, I am currently investigating CPU temperatures and factors affecting same coupled with heat removal.

Forgive me if this is 'old hat' with you: I don't know if you have considered the possibility of varying room temperatures or something else changing the air flow into/out of the computer?

If the room temperature varies, then there will be a different temperature noticed at the CPU cores. Other factors that could introduce a difference are thermal eddies (like mini whirlwinds) inside the case. These eddies could change and cause cold or hot spots inside the case. factors that could affect the eddies is a change in the airflow into the machine or out. IE a book or something near the inlet and/or exhausts will change things...

... Just a thought
