So, i just finished building my first Pc,but ive been extremely hesitant when using it, because it gets hot after 20 minutes or so by me just doing nothing, I don't know completely if its in the dangerzone of "overheating" but I have this old case fan that i want to use, my new pc has the holes on top to mount 2 extra fans however the old case fan i have is to small, so my questions are...

Can I use this old fan into my new build?

Despite the fan being to small is there a way i can mount it in my case?

EXTRA! I can currently control my fans on my desktop, however I don't know if changing the speed constantly can harm my computer in anyway, can it?

My build!

Changing speeds on your fans constantly won't hurt anything unless you turn them too low and starve the case for cool air. How many of what size fans do you have now, and how are the configured?

For the old fan, if you can get the mounting holes lined up, you can just mount it to the fan grill. Just stick the mounting screws through the grill and into the fans mounting holes. I would recommend mounting in the top/rear position as an exhaust.

Download and run HWMonitor or a similar monitoring program to get a good idea of what your temps are like at idle and while under load. If you want, you can post screenshots of each and post them here. We'll let you know if you need to be worried or not...
