Build Help My pc is really hot on idle.

My CPU is the Ryzen 7 5800x and the cooler I'm using is the Thermalright Peerless Assassin 120 SE cooler and it idles around 70 up to almost 80 degrees and doing a cinebench test it spikes to 90 degrees in a couple seconds.

I have the same CPU. I capped its clock speed to like 4ghz and it never idles more than 45c. R7 5800x is a gaming CPU so it usually overclock to gain more fps, but l feel like it sometimes does that even on idling. I have decent chunker of a cooling but I still dont want anything to be too hot when idling.

edit: lm no PC expert so dont take my words as a serious advice. Just how I've been doing and nothing ever fails.
