hi guys .. my pc seems a bit too noisy for the stuff i bought .. :S

stuff that could be making a noise :

OCZ 600W PSU - though everyone else says they're nice and quiet

2 x Hiper 120mm fans for the true push - pull http://www.hipergroup.com/products.php?lv=3&cate=15&type=17&pid=48 which are rated by the retailer as 20 db.

the 4 case fans can be found here http://www.thermaltake.com/product/Chassis/fulltower/kandalf/va9000swa.asp and are all rated under 20 db.

so why am i hearing so much noise? =P

and a pic of ze setup http://i285.photobucket.com/albums/ll54/Mitch92uK/IMAGE_008.jpg .. (normally the side of the case is on)

cheers!
 
OCZ PSU isn't StealthXstreme is it? I've got one and those are things are anything but silent, so there is your problem right there AFAIK it has a Yate Loon in it rated at 40db. It's by far the loudest thing in my case.

EDIT: Just looked at your pic, when you have so many fans close to each other you need to make sure they run at low RPM.

The noise is just like a low pitched dull hum .. nothing high pitched.

It is the StealthXStream yeah mate :/

How does the speedfan reading look for rpm's ?
 
A dull hum sounds like vibration more than anything. As a first step try isolating your hard drives from the case, even just taking them out and holding them in your hand whilst powering up to see if it helps.

Fans could also be transmitting vibration to the case, try getting some rubber isolation mounts for them.
 
As neoboy says, the 'quiet' OCZ PSUs are nowhere near as quiet as other brands like Corsair and Enermax.

But I think your biggest problem is that you have six fans in the case, which I presume are running at full speed. That's always gonna be noisy. I'd look into getting rid of some of them, or at least slowing them down - I highly doubt that your PC needs four case fans.

To compare, here is my setup (excuse the messy cables):

Both the case fans run at 1200rpm and the CPU fan at 900rpm, so it's pretty quiet. I run Folding@Home so my CPU (Q6600 @ 3.2) and my GPU (8800GT) are always 100% loaded. The CPU runs at about 60c in CoreTemp and the GPU at 50c.

So I'd say you could dump a few of the fans to cut the noise, especially if you're not hammering your components all the time. Your temps are pretty low.

Are they connected to the 3 pin headers on your motherboard or connected directly to your power supply.

The 2 CPU fans, rear 120 extraction fan and the front intake are all connected to 3 pin mobo headers, with the exception of one cpu fan being connected to the 3 pin section of a 4 pin CPU_FAN header.

hmm .. rather than get rid of the fans i'd prefer just to slow them all right down tbh mate. only problem is when i play with speedfan lowering the percentages nothing happens :confused:
 
yeah you have a lot of fans i would deff tryu and slow them down that can make a big difference. also what gfx card is that is that a gainwood 3850 ? i just got one of them and rheyt are a bit noisy,
 
How are your fans connected? Are they connected to the motherboard using a small 3-pin connector, or are they connected directly to the power supply using a larger 4-pin Molex connector?

Speedfan can only control fans which are plugged directly into your motherboard, and even then only if the motherboard supports it.
