Why is it so noisy?

[meduus]

Hey all,

 

I have "build" my first computer, taking an old computer of mine and changing a few things around. The computer is extremely noisy however. Can anyone help pin point what it is that makes all the noise?

 

 

COOLERMASTER 690

* INTEL i7 920 (SOCKET 1366) 4.8GT/sec

* 1GB DDR5 HD4890 (x16 EXPRESS 2.0)

* GIGABYTE EX58-UD4P, (INTEL X58) (x16 EXPRESS 2.0)

* 12GB DDR3 1333MHZ RAM *TRI-CHANNEL*, KINGSTON

* 750W CORSAIR POWER SUPPLY (80PLUS approved) 60A on 12V, ULTRA Noiseless 

* 1000GB SAMSUNG HARDDrive, 7200RPM, 32MB CACHE (1TERABYTE)

 

Cooling:

- one fan in the back

- one fan in top 

- both fans and the cpu cooler seems to be stock versions. 

 

What i have done: 

- removed one of the graphics cards as it was originally running two hd4890

- Moved one fan intake from the side to the top (the pc is positioned in a desk so there are more room on top than on the side)

- Turned the power supply around so it takes air in from the button (after reading up on it in here and finding that it should be optimal as the setup is no longer a tight sli system fit.

- put in an extra hard drive from my parent old computer 

 

What it should be used for:

- browsing and office work so extremely light load.

Fans, really.

Maybe your fans are set at 100% on BIOS

[meduus]

The fan speed goes up and down according to HWMonitor so I don't think they are stuck at a 100%

 

When you say fans do you mean the two "extra" put in or the fans on the power supply and the fan in the 4890? and is there a way to turn the graphics card way down as it is basicly only there so that I could plug in the monitor  

 

And is there anything I can do about it? I take it that I can't just unplug the fans even though the work load of the computer should be way below what it was designed for?

When you say "stock fans" are you using the actual stock CPU cooler? I suspect it might be that, go into the BIOS and read what fan profile you have active. I have mine set to full power however my computer has sound pads on the inside to absorb the noise so I can get away with it.

[meduus]

I am indeed using the stock cpu cooler. 

 

In the BIOS a setting was set to "performance" which I turned down to "standard", which seemed to help a little. Right now I am kind of thinking that the graphics card is the sinner (if not directly then because it is generating so much heat that the other fans have to work overtime). It is running at 64 degrees celcius with a fan speed of 2800 RPM.

 

 

Is it possible to almost completly shut down the graphics card but still use the vga input? (and then just use the build in graphics on the cpu) 

 

I am a little unpopular at my parents right now as the old computer (although pretty slow) was running completly silent (it did not have a dedicated graphics card and no fans except for the standard stock cooler) 

 

 

UPDATE: I have found an overclocking menu in the catalyst contol center where I can choose fan control on the gpu. by setting it to 20% manually the sound is down to a much more acceptabel level so the grapics card is defenetly the sinner. The problem is though that the temperature is rising rapidly in the grapics card, so it is not a permanent solution. (even though I set gpu clock setting to 500 MHz and memory clock settings 490 MHz, the lowest possible in that menu)
