Lenovo LOQ 15IAX9 is designed for high-temperature environments.
It's been nearly a year since I purchased my laptop, and I recently replaced its thermal paste for the first time. I used MX-6 paste. After doing this, I decided to monitor the temperatures to see if anything was off. I started Prime95 in 'blend' mode, and the readings were higher than I anticipated, particularly on cores 1 and 3. I haven't performed a temperature check before changing the paste, so I'm unsure if these levels are normal.
I understand this was a hasty choice. How significant is the temperature gap between the MX6 and PTM7958/7950?
Temperatures remained consistent for a longer period after beginning the stress test, which seems normal.
When both methods are used together, it's unlikely to work effectively. This is especially true after the paste has just been applied. The main reason modern laptops and some GPUs use PTM these days is to counteract the pump-out effect caused by repeated temperature shifts. Phase change materials like PTM are designed to minimize this issue.
That cooling method only handles so much heat. Or perhaps the heatsink wasn’t secured properly, etc. From the video I shared in my first response, the overall temperature stayed similar. Keep in mind you were running Prime95, while the video uses Cinebench—stress tests meant to push your CPU to its limits.
