Overheating P4 3.0c CPU

[pensxpress]

I have an Asus P4C800 1008 bios with P4 3.0c. I decided to overclock slightly and pushed the CPU to 3.18ghz. ran fine for about 2 weeks. Yesterday my system was reporting temp of 86C and was beeping. I restarted the system and set my CPU back to 3.0 to be safe. The room temp is about 70F and M/B runs around 78F. I have Artic Silver 3 thermal paste and the Zalman cU 7000 heatsink fan. At 3.0 speed, it runs at 32C idle and 38 load. I'm not sure why it was overheating. Anyone has any ideas??

welcome to Anandtech. perhaps one of the fans was malfunctioning at the time? 86C is extremely hot.

Once my fan on my 1.2 ghz tbred (those run extremely hot anyways) died and i didn't notice for a while...the mobo's auto-shutdown was off and no beeping occured. i smelt burning. i go into bios and it said 110 C...lol!

but yes 86 C is too hot. i think some Artic silver Ceramique and a new Heatsink/fan might be in order
[edit] i actually red the entire post now..nvmind. did the area surrounding the cpu seem extremely hot? Going from 3.0 to 3.2 isn't that big of a step to warrant a 40+C increase imo....perhaps a faulty thermometer?

That is way too hot... Curious how the temperatures at 3.0 are great, but only 180mhz higher, the temperatures are through the roof. That Zalman isn't a bad heatsink, what voltages are you using to get to 3180mhz? I would guess you wouldnt need any more than 1.65-1.675volts tops...

Seems like something else is going on, possibly a fan. Did you compare bios temp reading to asus probe. might try that just for eliminating possibilities. Also, what kind of PSU are you using - couls be something to do with the PSU unit. Good luck

What would be the difeence between asus probe vs bios temp reading?
Don't they come from the same sensor?
