Extremely Noisy CPU Fan

Lorry` SG

My desktop CPU fan has been very noisy for like er, 1+ year I guess, lol.

Everytime i perform a task or something, the fan will be damn noisy.

When i leave it there without executing any tasks (like just leave it there without even opening any programs or music player), the fan will also make noise.

The noise will take like 10 seconds or more. Then when i leave my com on and go to sleep, the noise is damn loud until i can wake up.

Very scary la. But the noise really will make you very dulan until you feel like smashing your computer lor.

What should i do? I heard that i need to open the CPU cover and clean the fan, but im not good at such things, im afraid i will screw my CPU.

But is it really the cause of the dirty fan?

Anyway my desktop is like, 3yrs+ old, if this helps.

Rednano SG

yup, clean the fan blades with dry cotton buds or use those mopping magic-clean type of cloth

Rednano is right. clean the dust off the fans. or, the fan bearing might be kind of loose. you can get replacement fans which shouldn't be too hard to install. they're about 8 bucks..

Check for loose parts and if wires are at the way of the blades.

If everything ok, then it is the energy saving mechanism of the computer lah, like the fan only activates when over certain temperature to conserve energy. You can change the power setting in Windows to see if it will be quieter.

I removed my heatsink and flush in the shower.

Don't forget to apply heatsink grease when fixing back your heatsink.

Don't worry, ever heard the saying "旧的不去，新的不来" (old one doesn't go, new one won't come), so the worse could happen if you screw up your CPU is, you get a new PC.

back up first and discharge your hands + switch off and unplug the comp.

anyway it's only the fan.....

MyPillowTalks SG

msot probably shoulld be overheating

apply thermalpaste, clean heatsink and resit heatsink

nightzip SG

A lousier choice would be, once you open the cover, dont dismantle anything, but use vaccum cleaner or blower (air temp) to blow or suck out the dust can already. If you afraid later cannot fix back the screws.

Else can always bring it to Sim Lim for cleaning maintenance, they do that. Usually they will do the vacuuming, change thermal greaze on the CPU, see whether you need more casing fans, readjust your wires etc. but it will be about $40-$60 for the service.
