PC Fans Too Loud (What Can I do)

[blackster]

Hi Everyone, I built a new pc recently (Spec in my sig)

However the fan noise is getting to me now and I to do something.

At the moment it runs very cool :

Geforce 7800 GTX Cards run at around 47-50 c Idle and rise upto 60-70 When fully under load (i'm talking about 5 hours of BF2)

The cpu temp idles at 33-35c and rises to 43c at the most, the chipset (fanless let me add) idles at around 37-39c and rises to 44 max when my room is very hot (ie central heating on)

I've got :

1 x 120mm (lian Li supplied) Case fan as the intake, thats running with a molex connector plugged straight into the psu

1 x 80mm (lian Li supplied) Rear Case fan again connected to the psu with a 4 pin molex connector

1 x 80mm (lian Li supplied) Top Case fan, same as above again

1 x 120mm Papst running on a Thermalright XP-120 again connected to the psu with a 4 pin molex connector as the motherboard wouldnt be able to take this anyway on the headers etc.


I might add that I've got 4 (yes 4) hard drives, one raptor and the rest are samsung spinpoints.

The question I want to ask is can I do anything to make the system more quiet as the fan whirring noise is doing my head in.

I've had a look at some fan controllers but they all only seem to take 3 pin plugs, another option would be to use a old pc mods rheobus and cut all the molex plugs off and have them connected using a blocklike connector.

But how much noise will it get rid off I dont know.

Anyone any ideas before I go deaf

ok chaps, thanks for the response,

firstly, water cooling is out of the question, i havent the time or money to be messing about with that, although it would be better I agree.

I'm going to have a play I think with the cables and try and reduce the voltage on each fan and see what temps and noise I get from doing that, as mentioned the graphic cards are still going to give a little noise and theres nothing really I can do about that unless I start adding more coolers, but I havent really got the time for anything major.

Thanks for the ideas I'm going to put a couple of them to the test.

Cheers

Cheers mate, I'm going to try that and stick a 3 way switch so I can switch to 12 v Full, 7 v Mid and 5 v Low.

I've just disconnected all the fans apart from the heatsink fan and the rear one, and the graphics cards ones are still going also and the difference is massive.

The chipset temp has rose about 7c and the graphics cards have rose about 5c each idle, but it is mainly the top and front fan making all the racket.

So I'm going to try the mod mentioned above, should I mod the headsink fan also or keep that plugged in as normal?

Cheers
