Computer Fan is Loud

How could I reduce the speed I have a windows vista and my Pc is quite old from 2009 so does that mean the thermal paste is gone (because I remove the fan) , I try playing with BIOS but no luck, also I try speedfan but nothing happen...my Pc is an Acer M3800 everything is default from factory...

I did face similar situation with my computer sometime back..u need to clean the fans maybe using a blower...Hope this helps..There is nothing wrong apart from this.

Maybe you have to many programs running, and the thing is jut getting to darn hot.

Took the fan off one of mine once, and simply slapped it back on. I'm sure the experts will say to clean up and re-apply paste. The computer survived the abuse, but given that the entire motherboard had a good mm or so of dust covering it I doubt that little tinker made things much worse.

So, how fast did the compressed air get the blades spinning ? Any idea where the dust ended up ?

I'd check (with Task Manager) to see if you have unwanted programs running, then maybe invest in a new fan (they're tricky to clean if really encrusted). I used q-tips (the geeks will kill me ). Said computer still works fine after about 6 years of such barbarity.

And they're really pissed! (that little supernova near the bottom of the pic is in their galaxy, not ours)

Well now you've set me off, the crud on my fan is probably my own.Come to think of it, some small part of said crud may have even blown across the planet (bit like the air Aristotle breathed) and landed on everyones fans ! Seeing as how we're all made of stardust, don't expect compensation from me anytime soon - it's ET's fault.

Anybody got a cure for a squeaky hard drive ? I dissected one once, and much to my surprise it wasn't a sealed unit. Seems logical - take it to a different elevation and the thing would either swell up or get squashed. It had a tiny filter covering an air-hole. I've no idea what size of particle it filters, but I'd guess that cigarette laden breath can get into it. It survived washing under a hot tap, but I didn't think at the time to use some sort of nicotine solvent.

Looks like you upset the dust's sensitive dynamic balancing on your CPU fan and now it's old rusty bearing is complaining. Putting the dust back might fix the problem, but then it might not. (LOL). Is there any noticeable play on the fan axle? If yes, get it replaced, lubrication-cleaning surgery will not always succeed. S.M.

If you, "didn't touched anything from the inside", how could you have, "(remove the fan)"?

Buy a new fan. It will have thermal grease with it.

You think your fan is loud? C.H., you ain't heard LOUD!
