    My PCH temperature can reach 79C quite oftenly when both CPU and GPU are loaded, is it normal?

    I own a G73JW, here is the spec: 840QM/GTX460M/1333DDR3 8GB/Intel X-25M 160GB + stock HDD.

    My PCH temp under furmark never goes past the low 70s. Is the thermal pad for the PCH in place and are all 4 under kb screws tightened?

    What does PCH stand for?

    Platform Controller Hub, it replaces the Intel Memory Controller Hub (aka northbridge) used in core 2 and older Intel CPU architectures. Some northbridge functions like the memory controller are now incorporated to the CPU. The PCH handles function typically managed by the southbridge and takes up the remaining northbridge function not handled by the CPU.

    Yes the thermal pad is there and no melting or anything that's why I found the 79C a bit strange. I also took the keyboard off to check those 4 screws, all quite tight.

    Oh and i just thought i should mention that 70C is the highest temp i got and room temperature was 26C (measured with a thermometer from the lab at work not some cheap thing so it was an accurate reading).

    What is your ambient temperature? I didn't check for the PCH temp when running furmark and prime95 together but after hours of civ 5 which is rather GPU and CPU intensive at the right settings, i never even got close to 70C.

    The room temperature is around 20C and that 79C was with Furmark and Prime95 run together. Now I can't check my PCH temp anymore after switching to a 940XM, maybe I broke something.

    I don't see a PCH temp reading either Hackness, just the wattage. Don’t worry about it.
    You DO get a reading for your core temps though don’t you ??

    Yep all 4 cores are reading the temp, just the PCH is gone :cool:

    IIRC (mine is in RMA), I'd get about 80 across the board.

    interesting, my PCH idles about 68-70 degrees, and under load, it goes way up to 79. strangely neither the cores or the rest go that high. could someone give me some advice how to check those four screws? ambient temperature is 23-24 celsius.

    edit: G73JW here, no overclocking whatsoever.

    Those 4 screws are located right under the Keyboard, those are the 4 you need to unscrew before opening the cover on the Keyboard side.
