Loud Fan, safety shutdown(Assumption),

September 22, 2012 at 05:43:26
Specs: Windows 7
I've just taken my HP laptop to a computer shop to get all the dust removed after thinking that was the problem but still the fan is very loud and after a while the computer will just shut down, and I don't understand what the problem is?? I will phone the computer shop on Tuesday due to the weekend but can anyone help me until then??

It seems pretty obvious the fan isn't working properly & the CPU is overheating. Why would you take it to a shop to have the dust removed? All you had to do was blow the dust out of the cooling vents with compressed air. If the fan itself is bad, the entire laptop wil have to be dissambled & the fan replaced. Proper thermal paste application is critical.

"No shop near me selling compressed air"

Cans of compressed air can be purchased at a lot of different places, you do NOT have to go to a computer shop. I don't know if you're in the US or not, but you can buy it at Kmart, Walmart, Target, OfficeMax, BestBuy, drug stores, etc.

Ever hear of an air compressor or tire inflator? They will work too.

Generally, air compressors are not ideal, containing moisture in the air stream and depending on the size of the compressor, it might be enough pressure to damage components. A small quality air brush compressor fitted with a regulator and moisture trap would work at around 25PSI and that should be reasonably safe.
Much easier would be a can of Dust Off or similar from any office supply store.

A noisy laptop can be that the laptop is overheating and fan is overworking to try to keep it cool, or it could be as riider mentioned and the fan's bearings are going. A test would be to install HWMonitor or similar and then shut it down to cool completely. Then start the machine and launch HWMonitor and check the temps and the fan speeds. If the machine is relatively quiet but it begins to heat up and the fan speeds climb with the temperatures, then your fan is probably good but you have an issue with heat, possibly your heat sink needs to be reset properly. If the machine starts with the fan noisy and heats up after a while but the fan does not keep up with the temperatures, the fan probably needs replacing (a bit of light synthetic oil found at hobby shops might help but the effect might not last).

Good idea. I just hope that the 'shop' did not do anything to void your warranty.
