Got FPS drops after cleaning PC?

I cleaned my PC fans inside and out. Before that, I had a constant 144 FPS in Fortnite, but just wanted to clean my PC because a lot of dust had already accumulated. Everything cleared back together. Since then I've been dropping to 80-50 FPS every 20 seconds, before that was never the case. Wonder what I did wrong, maybe someone find a solution?

Maybe you damaged something while cleaning. E.g. The connection between cooler and CPU.

The best thing to do is take a look at your temperatures, that works well with hwmonitor.

@ richert069 The temperatures are all normal, or the same as before

Hmm…

What about the max. Utilization? Maybe one component is overwhelmed.
