Suggestions on making my system quieter?

Hi,

Lately I have been getting annoyed at the noise my system is giving off when on the desktop and gaming. I am wondering what people think is the best method to quieten down the system.

My system:
E7200 stock (Did overclock it but removed that to reduce heat from that)
HD4850
Antec Sonata 3 case running a single 120mm extracting air at the rear
Antec Earthwatts 500W psu (80mm fan, 80+ efficiency)

Now firstly the main culprit in games is the HD4850. That is loud, it makes me want to cry its that loud. What is my best option to sort this problem out? I have loads of space as I don't really run any other expansion slots.

It is worth fitting a quieter fan to my psu or blocking it off from the rest of my pc? I am aware that the heat produced from the cpu and gfx card will be rising up towards it and that will be trying to extract the heat through the psu, making the fan inside it spin faster than needed.

Just doing usual stuff on the desktop gives me the following temps:

CPU core = 44C
GPU = 83C

Then I have 2 more temps in speedfan which I'm not 100% sure on.

Temp 1 = 42C (system?)
Temp 2 = 28C (hdd?)

Right now it is at a decent noise level, but if I do anymore or if the house is much warmer then it soon shoots up. Annoying when using TVersity to my xbox as thats when I want it quiet.
 
Oh sorry I missed that out. CPU cooler is an artic cooling freezer 7 pro and the case fan is controlled by a fanmate so I know it isn't the case fan producing the noise.

I do hear a high pitched noise from my graphics card so I guess when its the high pitched noise it is that, which is mainly in games to be fair to it. But I have something else producing noise, now I dont think it is the ac7 cooler. Thinking about it it could be a good idea if I get control of the cpu fan so I can see if it is that at all.

Both cpu and system fan running at 1200rpm.
 
Well been doing some more investigating. It seems that it is a combination of the PSU and GPU causing the noise.

Superewza,
The gpu cooler you have linked to there, is that better to go for over the artic cooling accelero s1? Would it be advantagous enough for the extra airflow out of the case, thus causing more negative pressure inside the case?

Also what do people think to swapping the fan in the psu to bring the noise down a bit? Also I have heard somewhere about using ducting to separate the psu to the rest of the pc.

You still need a fan for the Accelero, and the Accelero + Fan is a lot more expensive than the affordable Akasa.

Your Antec PSU is supposed to be okay, but it's still an entry level PSU. Most of the quieter PSUs have larger 120mm or 140mm fans in them and which run at lower speed.

Yes there are plenty of much quieter 80mm fans, if you feel comfortable in opening up your PSU.
 
I already have a spare 120mm fan which I can 5v or 7v it. So there isn't any extra cost for the Accelero.

Aye I know it isn't the latest greated PSU, just wondering what sort of fans are recommended to be used within a PSU.
 
Im using a Accelero on my 8800GT with no fan and it idles around 20C less than the standard fan and is silent
