Video card fan
 

My video card's fan has been making weird noises. It has this really loud hum noise coming out. It would go away sometimes too. I tried cleaning it using those air compressors without any luck.

Suggestions?

Sounds like the fan is starting to come loose a little bit. Those sounds you're hearing could be because the fan isn't spinning properly. So you should check to see if the fan is still firmly attached or not.

If your card is a popular model there may be a third party cooler. If your original fan is starting to fail, that might be the way to go. Unless you fancy a new graphics card, they soon become outdated.
