Noisey CPU Fan ? Loud!

StuartUK · 12-17-2005, 03:05 PM

Evening everyone :)

I'm stuck!
Got a brand new PC, turns on, but wow, how loud is that !
Its not far off the sound of a hair dryer !
Whether its relevant, it cost £300 ($500) for the base unit, ASROCK motherboard, with 3.0ghz Intel Prescott processor, but running it, my god, its loud... So i guess, the people who sell this range of computer sell it with cheap components right ???
So the Fan on top of the CPU must be a crap one, and dish's out a lot of noise..........
What do I do now, to get it quieter ? Just go and buy another CPU fan, swap them over, jobs a good un ?
I got an old PC with a Intel P3 chip in it with a quiet fan i guess, could i use that fan on the new processor ?

Oh, and looking in the BIOS, i think it said the fan or cpu was running at 5800rpm ?
Help !! :)
Cheers all

If you've got a poor stock fan installed, a new one might help. There is the possibility that it's not a problem with your fan though... though not likely, it could be that your airflow is just very poor, the thermal compound was not applied correctly or some cheap grease was used...

Answering these will help us give you a more accurate answer:
What temp is your cpu running at?

What size is the fan? it's possible you've got a junky stock 40 or 60 mm fan on there... if that's the case they have to run pretty fast to have any effect. If you're not sure of the size and you've got a digital camera, send us a picture

It's also possible that you may benefit from a new heatsink/fan unit, and a good application of arctic silver (thermal complound for good heat migration).

The first thing i would be doing is asking the Manufacturer/Retailer if this noise is normal. If it is just replace the fan with a good quality one that has a low decibel rating, (they are not expensive)
If it is not normal get them to fix the problem under Warranty
