I had a pc built for me that was suppose to be very quiet, using supposidly quiet fans and PSU but it's rather noisy.

When the CPU gets up to about 45 degrees tha fans come on and are rather noisy.

The PC has 2 fans other than the PSU. I need to check should one be sucking and the other blowing out of the box ? What's the rule of thumb of how to install these 2 fans, as I just want to check they are installed correctly.

The noise might be coming from the graphics cars in build fan i think

cheers

been and had a closer look. both the graphics card and the PSU are the ones making the noise. The fans are set up as follows:

front fan - flowing inwards
Top fan - flowing inwards
back fan - flowing outwards

is this the correct flow ?

Yup, thats correct. Chipset & GPU fans do tend to be loud OEM fans, I have replaced both mine with Zalman silent coolers...

I have Zalman coolers as well, think they where about £25 and they are super quiet. Well worth the little cash they cost!

i have disabled the graphics card fan as that was the one that contributed most to the noise . cpu running at ~47deg C and still too noisy for my liking. The PSU is now the noisiest, and i've tried playing with the power levels on the PSU

Mr.Manchester

Just replaced my stupidly loud CPU cooler with one of these monsters..



it was about £16 from www.aria.co.uk im very pleased so far

If you can make sure you get quiet 120mm fans, run slower and quieter but still shift a lot of air. Akasa Ambers are great. For the gfx get a Zalman replacement as mykp says. On the PSU front the best thing probably is to replace it with a near silent one.

For silence I recommend (having spent 100's of £'s finding out the hard way) is....

Fans - Akasa Amber Series, preferably 120mm
CPU Cooler - ThermalTake Silent Boost or Arctic Cooling Freezer
GPU Cooler - Arctic Cooling Silencer
Northbridge - Zalman Fanless Heatsink
Power Supply - Tagan Whisper Quiet
Hard Disk - Samsung Spinpoint Series

...also add a quality case of decent thickness and some sound deadening material (Akasa Paxmate) and to finish off, I installed an Akasa Fan Control Jnr, so I can set the fan speeds even lower than standard.

Might seem like overkill, but if you are like me and hate noise, then well worth it.

Oh and btw, general rule of thumb is to have the same number of fans for intake and exhaust. Ideally intake at the front bottom where the air is cooler and the exhaust at the top rear, because heat rises.

another vote for the spinpoint HDD....

Especially when used with the rubber mounting bushes that are supplied with some Cases... (beantech)

Super quiet !!
