Northbridge temps

[arkon]

I'm having a weird problem with my NB temps. When I start my computer up, NB idle temp is idling around 44. If I then put my computer to sleep and wake it up again (ACPI sleep mode level S3) the temp has dropped to about 34 (idle as well). It stays around there, even if I sleep and wake my pc again, until I restart. So basically after waking the pc from sleep mode my NB temp reads around 10c cooler for some weird reason, I am never able to get the NB temp to read under 40c without doing the sleep and wake up thing.

I see no real problem here.
A temperature of 44 Celsius for a NB chip is quite low.
That chip should take 70 Celsius just fine.
I think you are watching to much the monitoring software instead of really using your PC.

What is your CPU temperature ?!

Hi

I'm wondering if it is due to some bios or sensor glitch. Does the NB heatsink feel cooler aswell ?

A week ago, I accidentally hit the the sleep button on my keyboard and noticed that the cpu was idling 5-6C higher than norm, after booting it back up. Too bad I didn't make note of the mobo temp. heh..

I will try to replicate this now lol...

The screenie speaks for itslelf. Very odd !

What are you using to read the temps ?

Does the CPU temperature drop back after a few minutes of being higher than normal ? If so it could be that waking from sleep doesn't give the fan time to cool the processor down as it starts up. When booting from cold it has a bit of mass to help it.

Speedfan's graph shows a 13 minute window and after a few more minutes, it leveled off at 34C.

Nothing else is out of the ordinary as all other temps and voltages read as they normally do. Also, the cpu shows no activity.

Shutting it down/ cold booting it seems to be the only fix. hmm..

I can't think of any other reasonable explanation. Obviously try a different BIOS might work.

I'm not worried b/c I never use sleep or hibernate. The first time this happened was with the F12 bios.

I thought I had Windows set to not sleep and hibernate, I guess not.
