Is this (chipset?) temp too high for a laptop under full CPU load?

[Turbonium]

I'm running an older Dell laptop (GM965 chipset) under full CPU load.

HWMonitor gives me the following temps:

Mainboard (THM_)
76 °C (average)
78 °C (maximum)

CPU
~70 °C (average) (core 1 & core 2)
71 °C (maximum) (core 1 & core 2)

Note: CPU is a T9500

I'm assuming "THM_" is the chipset (Northbridge). If so, is this too high? Note that the temps for this sensor are always a few degrees higher than the CPU temps, even with normal system use (by around 6-7 °C as well).

EDIT: If the Tcase of the chipset is higher than my current temp values, then I can assume that my chipset is fine, correct? Also, Tjmax (which is more reflective of the chip's actual thermal max) is always higher than Tcase, correct?

Note the amendment I made to the original post. It helps narrow things down.

IMO i feel its a bit too hot.

but there probably isnt much you can do about it, as its an older laptop without taking it apart.

You could try to use some compressed air, and blow out the heat sinks located at the rear of the laptop.
But at that point without taking the thing apart to reapply new tim, your pretty much stuck with it.

Is this with stress testing, after some minutes, like OCCT, for example, or something like that? If so, the temps are quite good. If a real application, they're OK, but on the warm side. A little cleaning and re-applying of TIM would probably help temps, given the age, but those temps aren't worrisome, either.

If the GM965 is the same chip as the desktop 965 chipsets, it would stand to reason it would run hotter than the CPU. The desktop version was anything but cool running.

It's Folding@home (100% CPU load, but not a full system stress test by any means).

I did replace the motherboard at one point, but I don't quite remember if it came with its own thermal pad, or if I had to apply thermal paste. In any case, I'll probably open it up at some point and re-apply some TIM and see if there's any improvement.

F@H is basically a full stress test as it loads the system @ 100%.

Id say those are probably acceptable temps on a laptop when F@H.

If anything id figure out a way to get more air though the laptop... possibly a laptop cooler of some sort, that works.

But F@H was not really intended to be run on a laptop.
It will eat the life away from it quick.
