Thermal throttling few days after repasting.

I have repasted my laptop after it was running hot(97+°C CPU, 85°C GPU) while gaming. Just after applying the paste I ran intel XTU stress test for 3 hours during which the CPU temps never crossed 80°C and the clock speed was also consistent with no thermal throttling whatsoever. One week later the CPU thermal throttles like hell and is back to 98°C. GPU also is back to 85. The weirdest thing is all this has happened thrice. I have repasted 3 times only to get 1 week of cool performance each time. Why does this happen?

 

Themal Paste: Arctic Silver 5

Laptop: HP Omen 15 2019(dh-0138tx)

CPU: i7-9750H

GPU: RTX 2070 Max Q

CPU undervolt: - 0.150V

Ambient temperature: around 25°C

Have you tried a different paste?

No, could that really be a paste problem?

I was also experiencing a weird thing with the Thermal Grizzly Kryonaut, which was supposed to be a high quality thermal paste, but after applying it on my 8086K, the temperature during a stess test was worse than with some generic thermal paste I got with the AiO.

Make sure the fans are not obstructed in any way and are getting good airflow. Also make sure the cooler is on properly and not loose.

I am far from an expert in this so please correct me if I’m wrong.

I see, but why would a paste work well at first then?

I don't know. Maybe it's old and it separated the water from the paste. The water then accumulated in the front of the tube and after a while on the heatsink it evaporated? Try to mix it well before installation. This is the only thing I can think of.

Yeah, similar things happened with the Artic MX-4 on my ThinkPad P53. I'm regularly hitting 100C in Fallout 4 right now. Going to try again with Kryonaut.

Those temps are normal.

 

You saw lower temps in XTU because your GPU wasn’t being stressed in conjunction with the processor. Gaming uses both and is going to generate more heat. XTU also isn’t a great source for torturing a processor, use prime95 next time.

Well XTU hit 100C again. It didn't when I first changed out my thermal paste to MX-4. Well, my Kryonaut arrived today. Let's see how it does.
