Hi I recently bought this system and its some random fan making loud noise inside my system. I got the computer working and after 2 hours the fan started making noise. Every 10 seconds or so. Or when i start benchmark or a game.
Also when i shutdowned system for about 10min and started it the problem didnt come back until like system has been on for 5 minutes. Is this just the fans heating up and doing what they should or is there problem? No dust inside, temps under 60-70 while gaming

Can you describe the fan noise?

Fans noise that is "loud spinning sound like is turning faster" is OK. You'd want to check temps with a tool like HWMONITOR (google it). Under heavy load fans will spin up.

Fan noise like "bearing are failing, fan is trying to turn but is having trouble" are not good.

google "youtube computer fan noise" and watch a few videos. See what other fan noises sound like and see what caused them.

fans making noise is not good. Laptop or desktop. Glad you blew the dust out of the PC.

You can usually hear which fan is noise in a desktop. If you can't then put a wooden chopstick on the frame of the fan and the other end NEAR (not in) your ear to hear what is going on. In a laptop there is only one fan, youtube will have videos showing how to replace.

Good luck. You can hurt things if fans stop making noise by stopping. CPU fans are monitored, the PC will stop. Chassis fans and video card fans are a bigger problem.

Hi, thanks for the answer. I didn't blew the dust out cuz its brand new computer.

What do you think caused the fan to start up making noise AFTER the computer has been on for 2 hours?
Also, if I open the case, should it be easy to reseat the fans? Especially the cpu fan? Also, I think it is the case fan I got three of them in there, the side door of the computer is kinda vibrating, so do you think reseating fans is a good solution? Can't test this because it's so random when the noises come.
