Why is it heating up?

Question

Processors

The computer began to warm up, or rather, I’m not sure, I didn’t follow it for a long time, recently the RAM flew, until I found a problem, they removed the percentage a couple of times, put thermal paste on it again and instead of 16GB I put 8, could it be that something is not so with thermal paste or what could be the problem, jumps from 62 to 75, I saw 80 a couple of times, the ryzen 1600x processor, it seems that before that everything was something around 60g maximum and such a question is whether it can get warm due to the fact that there were two channels of RAM and it became a single channel and only 8, I think not, but still

Answer 1

Most likely, problems with the cooler fan, see how fast it spins at high temperatures on the processor.
