From the best ones I have tried, 35-38 degrees on YouTube and even when I open Spotify and play games (in alt tab).
In games, it reaches 43-48 degrees with the help of the CPU cooler (Intel Core i3-10105F 3.7GHz) and 2 fans on the case. I believe with the CoolerMaster Masterliquid ML240L V2 RGB CPU Cooler, it will be just what it should be.

So, I bought 2 of these. It costs 3 euros, guys.
If you are crazy overclockers, it's better to go for a slightly more expensive one that can withstand high temperatures!
But for me, it did the job from the moment I couldn't overclock.
Where I had idle 35-38 and after many hours of gaming, it reached 70-72, I applied the paste and had idle 25-28 and after hours of gaming, I didn't see it go above 60, I really played Triple AAA games like Battlefield 1 for over 3 hours, it didn't go to 60, it stayed at 59...
I didn't expect that.
This paste can be used many times.
I have used the first one 4 times and it still has half left.
You shouldn't put too much thermal paste on the processor.
It needs a very small amount, like a small ball in the center.
Also, watch a video on YouTube to understand better!
5/5 from me! I will buy it again if I need it.
