Hi all, recently my laptop seems to suffer from thermal heating issue. I was casual gaming previously without issue but notice FPS dropped badly for past few weeks.

I installed HWInfo and found the CPU is hovering around 90c even under light load (Normal youtube surfing with only 1 tab open)

I have done the following but the CPU temperature seems to be still high 90c under normal load.

1. Reformat whole laptop
2. Send laptop to shop for servicing (Fan cleaning and apply new thermal paste)

I have attached the HWInfo graph for reference while I'm surfing youtube with 1 tab open


The following is my laptop spec:
Thinkbook 15 Series
Intel i5-1135G7
16GM RAM
Intel Iris Xe Graphics

Also wondering could it be the fan is not working properly leading to heat issue. I did feel the fan is sucking in cold air from the vent but the keyboard side of the CPU location still feel hot.

Welcome any feedback on this

Yea the graph is taken when I'm on my desk so the airflow should be sufficient.
I did take apart the laptop just now and check the fan is clean, did not find any chunk of dust that's blocking the airway.
So not sure if the thermal paste really not working. I might give the honeywell thermal paste a try

I'm trying to source new fan for my laptop. Meanwhile wondering if the copper heat pipe will have any effect on this or not. Though I think the chance of heat pipe causing issue is quite low?

The thing is HWInfo cannot detect any fan speed or RPM/Fan Speed %. Not sure if this is a sign of fan being kaput or there is no such sensor in the laptop.
I even download other tool to detect it but cannot find fan speed information

I just did a laptop reformat but still same result. Will malware still persist even after reformat? I did not keep any file during the reformat so it's clean format.

I just ordered new Honeywell PTM 7950 thermal pad. It will arrive few days later.
If the thermal is still that high, then will order new fan (Unfortunately my laptop is international version so need to source it via AliXpress and will definitely take one-two weeks again).

Any result will let you guys know. Cheers

Hi all, some update here.
The main culprit seems to be the thermal paste.
I disassemble the laptop and found one of the heatpipe screw seems to be stripped. I suspect the repair shop try to take out the heatpipe by bending it but fail to do so. This also cause the original thermal paste don't have enough contact with the heatpipe.

I manage to take out the stripped screw and put on the new Honeywell Thermal Pad. Been running it for a while and the temperature is much more lower.


Thanks all for helping troubleshooting
