Rattling noise

I can hear a rattling noise in my pc whenever my fan spins fast. What is this coming from? Is it something I have to worry about? (I have backed up everything recently and I barely make software changes to computer and I am also getting a new PC soon anyway)

If it only happens when your fan is spinning I'd say it's a good bet the bearing in the fan might be on the way out. It it's the CPU fan, you might want to think about replacing it as if it fails your CPU temps will go up very quickly, and your PC would not be happy with that.

If it's case fan, and you're getting a new PC soon anyway, if the temps are hardly affected with the fan disconnected mybe you can live with it. But generally speaking, you need at least one working case fan to assist with cooling.

In addition to what Tanya said, it could be an OK fan that vibrates in its mount as the RPM increases.

You say "my fan". Here's hoping you have more than one. Any PC should have at least 2. Most have 3 or more.


Get your ears inside the case close to the suspect fans. You can stop case and CPU fans for a couple of seconds to see if the noise goes away.

Case fans and cooler fans are generally replaceable. PSU fans are replaceable if you are qualified, but otherwise should be left alone as it can be hazardous to your health.

I meant my CPU fan because it spins up faster when the CPU usage percentage goes up. I do have other fans. I don't think it is worth to replace it since I have a high chance of getting a new PC in a few days. (Unless I am going to use the PC for some other use but not as my primary)

CPU cooler/heastsinks can come loose and rattle, especially if they use metal on metal mounting parts. So you might check the mountings to be sure they are snug and connected correctly too.

the motherboard/mobo tray can also rattle.

as can parts of your case. my corsair air 540 has an annoying humming sound when the fans are at high rpm, it stops if I simply tap the top of the case.

easiest way to check is to open your pc when its on, stick your head in and listen. that should help pinpoint where its comingcoming from

Thanks everyone. All I wanted was to know where it was from, but you guys went further, which was not required but I do appreciate. I will mark as solved since I'm ordering a new PC later today anyway.

Haha. Very funny. (Being sarcastic) I already know because I made long thread about the best pc build possible and I FORGOT to say that it is a fantasy build. It was 5+ pages of discussing just for a fantasy build.

Hard drive won't stop rattling
Ever since installing Win 7. Often for 5 to 10 minutes. Thought it was Avast (from task manager processes), uninstalled Avast, still the thing won't stop except very ocassionally when I'm doing specific tasks. Is this normal (mem paging, etc)? I'm ready to go back to XP.
