Problems cooling an 1800XP on a KR7A-R with SK6

[Storm27]

Hi,

I've been running my 1800XP at stock speed for a couple of
weeks now (haven't really o/c'd it yet). Problem I'm getting is
the processor temps are in the mid 40's idle and early 50's
on load. A number of times my computer has bombed out of
a computer game and dumped me back at the desktop, with
the temp of the processor at 52c. I wouldn't have thought
that was top hot really ? Case temps are between 20-26c.

Anyway I've had a feel of all my fans to see what the air
is like coming out of my PC. I've got a tornado coolercase
so have a load of fans, the two on top are blowing cold air
out my case, so is the one at the back, inbetween my
graphics card and my processor, but my PSU fan is blowing
warm air out the case ????

Any ideas ?

I've got;

1800XP, KR7A-R (all running stock speed), GF2 GTS, processor
has a SK6 with ys-tech 60mm fan on it.

My wife's pc has a 1gig athlon at 1.46gig so not that much
less than my 1.53XP. Here idle cpu temps are a good 6-7c less than my XP ?

Also I've noticed DVD movies start jumping slightly when it
gets too hot.

I'd have though somewhere in the early 50c would be fine ?

I've got a 300w Macron PSU. Could it be PSU related rather than
heat ?

Those temps are high but not high enough to crash the puter, I wouldn't think. Are you using thermal paste on the die? Try removing and reinstalling the SK6. Your case temps look good.

Yep I used thermal paste (not ASII though). I tried a little
experiment, I disconnected all the fans in my PC expect the
CPU one and the PSU one (which blows air out of the case).

I watched in the bios as, while doing absolutely nothing,
my cpu temperature went up to the mid 60's. With one fan
blowing cool air into the case the temp is at high 50's
and climbing.

I'll try your idea and reinstall the SK6. It should be on straight
cause I got a shim. Ah well I'll try again. Cheers for the advice.

PSU fans always blow hot air. Within seconds of turning one on its immediately hot.

Try running long stress tests (e.g. SiSoft Sandra burn-in) and see if your PC locks or anything. If not you should be ok. A temporary fix to cooling problems is to underclock your CPU.

52C doesn't sound too bad. Remember onboard probes are inaccurate a lot of times (which could mean higher or lower actual temps).
