So whenever I do anything CPU intensive, aka play a game, my computer starts making this annoying revving noise similar to a vacuum cleaner. I'm 80% sure this noise is caused by the CPU fan speeding up and slowing down. This noise persists until I shut down my PC and start it up again, even if I'm not running any intensive programs. I cleaned the inside of my PC, specifically around the CPU fan, but nothing happened. I tried using some program called Speedfan, but it's hard to navigate, and I'm pretty sure it won't fix my problem.
Here's the video. It might be hard to hear, but usually the sound it makes is a bit louder than this. If you can't hear it or the video is down for some reason, it basically speeds up quickly for one second, goes silent for about ten seconds, and then repeats. It makes a noise similar to a vacuum cleaner.
Specs:
Windows 7 64 bit
CPU: Intel Core i3
Motherboard: The one that comes with a Dell Inspiron 580
PSU: Corsair Builder Series CX 430 Watt
Graphics Card: MSI AMD Radeon R7 260x
What's causing this, and is there any way I can fix it?
