Celeron 533@800 temp problems

[Cpt. Duke]

I have been running my FC-PGA Celeron 533 @ 800 for the last 12 months without a hitch. Last week I upgraded to an Athlon setup, so I gave my old setup to my sister. For some reason I can no longer reliably run the setup at 800 due to overheating. I'm using the same case (In-Win A500) and the same exact power supply (PowerMan 235w) because I had to upgrade to an Athlon-approved power supply myself.
The setup in question is an Asus P3V4X, Abit Slotket, Global-Win fan and the Celeron.

My question is this -- because this is a slot 1 motherboard, how reliable is the CPU temperature reading in the bios? Is it really measuring the cpu or just the temp of the slotket or the Slot itself?

When running at 800 I can reliably run windows until the PC speaker gives off the warning sound. According to the Via hardware monitor, the CPU is running at 90 celcius. How is this possible?

Shut that puppy down and remove the slocket.

Then remove the heatsink. Couple of things, first, dust bunnies build up which cause temps to rise over time, blow them out with some high pressure air. Thermal Paste or heatpad??? Thermal paste is way better, just be real careful removing the thermal pad if you haven't already, then reassemble with the paste.

You should be running in the 43*C to 50*C range with that celly, a little less if you switch over to a Delta screamer on the heatsink.

Carefully reassemble with a fresh coat of thermal paste and see if the maintenence helped. When assembling, make sure the heatsink is making good flat contact with the CPU.

You can doublecheck this by assembling, then unassembling once, the thermal paste pattern will tell you the whole story, then back together again for good.

Somewhere is all this, your temps should drop a bit, err, hopefully, quite a bit.

Good luck.

Thanks Baldy, I'll give it a try...
