I have a desktop with a BTX case and a Pentium D.
I've had it completely restart a few times now, when I reboot it the bios says there was a "thermal event - (CPU overheating)".
Checked the case, clear of dust and the fan was turning. Just for good measure I switched out the fan, but it's still happening.
Checked it on SpeedFan and the temps seem to be normal, but it always restarts when I've got something else up. If I put the system under load I can hear the fans spin up and it keeps the temps withing good range.
It's almost like the system forgets to spin up the fan before it overheats.
Any thoughts? Thanks

Re: Overheating issues
Did you also replace the thermal interface (thermal pad/heatsink compound), or only the fan?

Re: Overheating issues
I didn't. The fan doesn't sit on the heatsink since it's a BTX case so I didn't feel a need.

Re: Overheating issues
I feel your pain. I had a Pentium D 925 for a while, and that CPU was the hottest one I've ever bought, by far. The two Preslers on one die was a stupid idea in the first place. I had a AnticZone (sp?) HSF, and when playing HL2 or Crysis it constantly overheated.
I know one of the problems I had, was it got so hot the outer metal shell of the CPU actually warped, so only about 30% of the face was in contact with the heat sink. I "wet" sanded the top of it, and the heat sink, and it did vastly improve the cooling, but it still ran about 14-20 degrees hotter than most proccessors I've owned. I just ended up throwing it out and buying a Q6600.
In all honesty, there are some great and cheap 775 chips now, so I suggest you buy a new one. You can grab a E7200 for about $100 or so, and overclock it to 3.6ghz on air easily. Or spend $60 more and grab an E8400, it will overclock to 4ghz on air considering it's a nice cool 45nm process chip. Lots of cache too.

Re: Overheating issues
Hey, thanks.
I'm thinking I'll just save up and get a new one eventually. I switched to 32bit W7 instead of the x64 and don't seem to be having the problems anymore. It's actually a gateway, could you even switch chips and have it still work?

Re: Overheating issues
Depends on the motherboard/BIOS. Some boards support Pentium D but not Core 2 / "Pentium Dual-Core" chips.hearld500 wrote:Hey, thanks.

Re: Overheating issues
Thanks, good to know that might be an option.
Well, it's almost been a week since I installed the 32bit verision and still havn't had a single "thermal event". Any ideas why it wouldn't be doing it now?
