Does anybody know of any pc fans or anything along those lines which will reduce the amount of noise generated by the pc? Occasionally I like to leave the pc switched on overnight downloading some big files but i get grief from my girlfriend over the amount of noise it makes... any suggestions? :)

Papst are the quietest, or change any 80mm's for 120's, or go for water cooling :)

Try Quiet PC - they do a whole range of fans'n'stuff.

Panaflow fans are THE quietest...

purely from what I have heard I was told papst fans were the quietest?

I settled on 34cfm 80mm Papst fans as a good compromise.

LOL Dom ;), the correct Papst are just as good and quiet as the correct panaflo's in normal use :) I have lots both.

If you don't want to spend the earth, look at getting some of the laser blue LED colermaster fans on Ebuyer, they are cheap at around £5 a shot and are quiet anough IMO. Combine that with a decent heatsink and fan combo for you CPU (which in a normal system is prob the biggest source of noise anyway) and you should be happy.

Cheers,

Nick.

panaflo L1A fans are the quietest 80mm per flow of air ;)

i buy from Dorothy...

As said... 120mm fans are quieter than 80mm, if u run them at a lower voltage... but if ur looking for a simple solution, then go for same size fans :)

NMB are great fans too..
i have a NMB 92mm (cooling cpu using a Zalman Flower cooler), a Panaflow 80mm (cooling the graphics card using a Zalman Heatpipe cooler), a NMB 120mm intake fan, a NMB 120mm exhaust fan - all controlled by a Zalman multifan controller :D

The noisiest parts of the system in order were:

cpu fan
case fans
graphics card fan
powersupply fan

LOL @ Nick, i'm running a couple of the blue LED colermaster fans from Ebay!! through a sunbeam rheobus...

Stick a big heatsink on it that can take 80mm fans. Then you can have a big,slow ,quiet fan. You may even be able to get a fan adapter for your existing heatsink so it can take a bigger fan.

What make is your mobo? With ASUS you get the Q Fan bios setting which throttles back the cpu fan if it isn't running under full load.

Another vote for the Coolermaster LED fans here.
About a fiver each for 80mm fan from overclockers. Reasonable throughput of air and quiet at 25dba.

Papst are renowned for this but more expensive.
£14 for a 19dba fan with slightly lower throughput.
