Wouldn't hurt. But you said it yourself...'CPU-intensive'. Your CPU is going to work harder, and therefore generate more heat. So the fan is going to work harder so that it can cool the CPU down. Having a clean fan would help it cool down.Sometimes when I'm playing games or encoding media, or other CPU-intensive tasks, my fan blows harder and makes quite a bit of noise. Like a very low humming. Should I clean it out?
When it stops cooling your CPU.Also, how can you tell when a fan needs to be replaced?
Also, inside my case there's a little square box thingy saying "cooling." What exactly would this be, a heatsink? I looked on newegg and the pictures don't look like mine.
Dust will reduce the fans effectiveness as well as weigh it down, increasing the heat generated within the fan. An uneven load of dust will cause bearing wear.Should I clean it out?
Some will get noisy and annoying.Also, how can you tell when a fan needs to be replaced?
It sounds like a duct. Funnels concentrate airflow while tunnels can increase flow as well as direct it.Also, inside my case there's a little square box thingy saying "cooling." What exactly would this be, a heatsink?
Have you tried reseting your monitor?Hey, I was playing a game(empire earth in case you want to know) and came out of the game and now my monitor has like a bluish tinge to it, it's really annoying. I've tried changing all my settings on my monitor and in the windows settings, nothing fixes it. Tried turning it on and off, still nothing. What's wrong?
