PCH Temperature up to 70°C

[Benoit74]

Hi all,

I've been playing with C6H and a 1700, and so far I could do a stable 3.9Ghz with 32G of ram 8x4 at 3200Mhz using CAS 20-20-20-48-75 2T.
I've ran that for more than a day, and I see that my PCH Temperature stays around 61°C on IDLE, and go up to 70°C on Load.

After running about 15 hours of F@H using both CPU and GPU I get the following temperature reading using HWinfo64 v5.51-3135:
- CPU (Tcl/Tdie) 59°C (max 66°C, avg 52°C)
- CPU 64°C (max 71°C, avg 56°C)
- Motherboard 43°C (max 43°C, avg 40°C)
- CPU (socket) 52°C (max 52°C, avg 48°C)
- VRM 54°C (max ??, avg 50°C) (the max reading had an issue and was reporting 101°C, but it clearly never been that high)
- PCH 65°C (max 68°C, avg 64°C)
- GPU 66°C (max 67°C, avg 63°C)

After gaming for 1 hour on Ghost Recon, the PCH went up to 70°C !!

I wanted to know if that's safe to have such a high temperature for the PCH, and also, I wanted to know what I could do to get a lower PCH?

Talking about this in the oc.net forum I seem to be an alien there, everyone seems to have PCH between 45°C and 55°C.

Could you please let me know if maybe the problem could be with the heatsink of the chipset that could have been badly seated in factory?

I've done a Clear CMOS and I'm now doing a similar test with default to see how high it'll go, but already I see PCH went up to 64°C...

Thanks for your help

Mine hits 63-65C, dont think it a problem. Think the max temp for the PCH is 80-100C so 70C is ok.

[Raja@ASUS]

That temp is normal for a PCH.

[Dazdigo]

Mine is around the same temp. Hopefully the m.2 3d fan holder I just bought would move enough air to drop it a few degrees.

Especially when it sitting under the GPU, It's not the most ideal.

[Raja@ASUS]

Case ventilation and airflow make a difference, too.

[Benoit74]

Thanks for your answers.

Indeed I confirm that case ventilation makes a huge difference: running all fans full speed for 10 minutes (including GPU) will bring the PCH down to 48°C.

But I can see that with a normal ventilation speed on IDLE (CPU 300 RPM, Case 500 RPM, GPU 500 RPM) the system stay pretty quite and the PCH sits around 54°C.

It's only during high load (ie. some demanding games) that both GPU and PCH will raise to the 70°C.

Thanks for confirming it's not problem, now I'll sleep better, one thing less to worry about

That temp is normal for a PCH.

Does PCH have sensor within or one placed on mobo close to it?

Cheers .

Just found this threat by searching the web. I was wondering, if 60-62 C° is normal for the PCH under load.
So I guess it is?
normal workloads raise the temps only to about 42-44 C°
I also use the CH6
