Phenom II running at weird temps?

Last response: in CPUs

Hey, I just got a Phenom II x4 965 Black Edition, and in Speedfan, the core is at 35C-40C but the "Temp1" is 45C-55C which one should I be watching, and is 55C too hot for the Phenom II?

Temp one is a temperature at some point on the motherboard, I think the Northbridge, not the CPU temp. The only temperature you should look at for the CPU is the core which is at 35-40, quite a nice temp. I believe that this chip can handle at least 70C, but I am not certain.

Okay great! but what do I do about the northbridge? Do I have to get a fan on that? Or is that temp okay?

Before doing any hardware changes, I would check and see if Speedfan is indeed showing the right temps.

I read elsewhere that a good way to test is to stress your system for ~10 minutes, then reboot quickly and find your system temps in BIOS, see if they are anything like what they were in Speedfan. Try this at some point and let me know.

Hey, the bios temps seem to be on track with the speedfan temps... maybe +- 1C, but that's probably just from rebooting.

Ok, so if the Northbridge temp shown in BIOS is the same as temp 1 in Speedfan, then the readings are probably accurate. What were the temperature readings after you ran a stress test?

53C during and after stress test.

53c should be fine as a maximum temp. My temp 1 usually shows 45 at idle and can get as high as 52 when doing video rendering. If your Northbridge doesn't get much higher than this, you should be fine, but if you are concerned, you can try mounting a fan. Most motherboards can facilitate this, and have a dedicated fan header (NBfan), but you should have a look for a guide on your motherboard or chipset to make sure.
