What are normal G73J Intel PCH temperatures?

Majority of the people are mainly concerned about the CPU & GPU temperatures, which might get under control by a good repasting job. Some time ago I realized in HWINFO my G73JH shows the highest temps of all the measured sensors in Intel PCH.
When normally using the notebook without in my work (MS Office, outlook, few chrome tabs open, no gaming and no videos watching) the PCH temps are around 80°C, individual CPU cores 60°C-65°C (with a single digit utilization), GPU sensors 65°C-70°C.

During the weekend I played Payday and my PCH temps raised up to 107°C according to HWINFO.

I'd like to ask for some opinions if that's ok, or I should do something. We have winter in Europe and rooms (either home or office) are usually heated to ambient temperatures between 22°C-25°C.

 

I believe that is because of you cpu/gpu having high idle temps. Also temps are quite high for simple tasks. I would recommend opening up your laptop and cleaning it up using compressed air, and doing a repaste of your gpu/cpu.

 

Similar usage at similar ambient temp for me - all below 50 C Once it is pasted and cleaned be sure to prop up the back about 1 inch (I use a text book). ALSO are you over clocking? I am not - 400/1000 on GPU .95 V

 

Thank you guys. I have higher GPU temps (comparing with those who repasted or reported nice temps at all) since I bought my notebook (April 2010). About year ago I RMAd the notebook after a failed bios flash and included the request for repaste, but I don't know, if ASUS repair man did that or not.
I don't OC neither CPU nor GPU - I'm only using registry tweaks for CPU to support the SSD drive. All the 4 cores frequencies are continually jumping in HWINFO from green ~900MHz through yellow to red ~2980MHz even on idle.
I was planning the repaste job together with the 920xm upgrade in about 4-6 months from now after the warranty is gone (April/May 2012).

So basically you believe the repaste may solve the PCH temps as well? I'm a bit curious, because the PCH is warmer than CPU/GPU by 15-20°C so I don't think the PCH gets warmed by them, rather opposite.

 

When you disassembled the laptop, you probably noticed the thermal pad under the top assembly. That thermal pad is in contact with the PCH and the heat is dissipated through the keyboard. At least that's what i figured on my own, there is no confirmation from Asus for this.

My 920xm is at 50C, PCH at 52C.

 

Tijo is right there is a small square grey thermal pad on the metal plating attached to the underneith of the casing under the keyboard.

Your PCH temeprature should not be hitting 107oC go back in and make sure you have not dislodged that thermal pad as it is easy to miss when dissassembling. After a 24 hour CPU/GPU stress test on my maximum overclocks in a hot room mine only hit 82oC.

 

I haven't disassembled my notebook except opening the bottom door for installing the SSD drive. So it's possible that the ASUS repair man during the RMA forgot to put back the thermal pad for the PCH when assembling the notebook back.

In such case should it mean the best would be to RMA the notebook (I have still ~4 months of warranty) and let ASUS fix the exceeding temperatures (but they don't seem to generate any noticeable problems)? Will they believe me I didn't cause the problem myself by inappropriate assembly? Or would it be simplier first to disassemble my notebook and try to diagnose the issue dyi? How may I obtain the (if?) missing thermal pad?

For me it is very critical to use this notebook for my work and its hard to afford to loose it for 1 month due to RMA.

 

What are your other temps like>? no temp should be over 100oC especially not over a period of time or you are asking for hardware failure, I am suprised it has reached that high unless there is a problem with the thermostat reading the temperature wrong something is not right. Take a screenshot and RMA it but post back about your other temps first.

 

I would also use another temp monitoring software to double check. I used to get something like that on my N50, HWmonitor would indicate THRM at 105C while everything was frosty, it was also making the fan kick into high gear which was getting rather annoying. I disassembles the whole thing, found nothing put it back together and it was working fine again, never found out what was wrong.

I was out of warranty, but Asus acknowledged that there was a problem and that i could send it back for repair so if you are still under warranty and you want to RMA, Asus should be ok with it.

 

I just called to ASUS and they'll accept the RMA due to overheating. They said they'll cleanup the fans and if needed fix the cooling system.

Now I have to prepare for RMA and borrow some notebook for my work .

 

I've got my notebook back from the RMA after a week, which was pretty fast. Asus reported they cleaned up the notebook and replaced the "cooling unit" without specifying which parts exactly were replaced.

The temps improved by approx. 10°C - Intel PCH dropped in idle/low usage to 70°C and during gaming to 94°C.
CPU temps were not that bad even before and GPU temps improved to max 95°C during gaming.

I think I cannot get anything better from ASUS, since the warranty will be over in May 2012 I'll take care myself.
