Can memory affect CPU temp?

[Jan Alter]

Hi,
We (two 10 yr old students) and myself (58), just put together a box at
school on an MSI KT6V-LSR mb with an Athlon XP -2700 cpu. I videotaped them
doing this so we could make a DVD of the process.
We used the AMD stock HSF and a stick of Viking DDR 2100, 256 mb RAM. The
temps on this showed the cpu running quite high, at 52 deg (case open). C
without any OS installed. The fan speed was running at about 2800 rpm. The
next day I decided to change HSF fans for a Thermaltake Volcano that I had
as a spare. I cleaned the the cpu, put a bit of Radio Shack cpu grease on it
and installed the fan. The temps went down to about 46 deg. C and the fan
ran at 4800 rpm.
After installing XP I noticed that the temp had shot up to 58 deg C (case
open). It's been staying there and the box seems stable, but I'm wondering
if perhaps changing the RAM might have a bearing on how the cpu temp is.
I've put together a couple of dozen AMD boxes and the highest the temps go
is maybe 48 deg. C. This is an anomoly to me. Is there anything else I might
try?

Thanks,

What percentage CPU usage is the machine running at? (Check task manager)

P.S. The CPU usage can explain a difference in temperature. But the
temp itself I don't think is anything to worry about. If you get much
past 70C and/or are experiencing stability issues, then perhaps you
should be concerned.

Possibly. Data may or may not pass through the CPU. With DMA (Direct
Memory Access) enabled data can bypasses the CPU. CPU temperature can
fluctuate depending on how much work it is doing.
