So, I've got some extra time on my hands and have been trying to determine why my computer is so loud. It isn't any abnormal noises, it's just a constant humming noise that is so bad, I can't sleep with my computer on. I've been looking at reviews a bit more in depth of each of my components (especially CPU/PSU/GPU [fans]) to see if any of them have been known to be especially loud. I have the cool'n'quiet software on my computer as well.

I bought a generic cheap case and also, I have a Thermaltake 80mm Secondary Case Fan going. Other specs are below. Any ideas of what could be the issue and what can be done? Thanks in advance.

EDIT: Also, I'd like to mention my temperature is usually under 40 degrees C so I don't think the fans are working that hard.

Cheap case fans and the fan grills stamped out of the case cause turbulence which makes noise.Cut those out and buy some low speed high cfm case fan's and or get a rheostat to control fan speeds to lower noise.And you can insulate your case to.Also rubber fan mounting studs etc .Just google quite computing

Also, the stock fan on the 6600gt is probably quite loud.

Use 120mm case fans where possible, instead of 80mm.

I have the same mobo as you do. Mine is one of the earlier additions. The chipset fan is increadibly loud and runs at 6k + rpm. This may have been updated on later models,prob in spring of 2006.Thus cool and quiest wont cure this problem. You cant regulate the rpm of the chipset fan through your mobo, even with programs like speedfan etc..

Here are two ways to fix the problem.
#1 free. Plug the chipset power connector into the cpu connector on mobo, if it reaches, then through cool and quiet or speedfan, turn the rpm's down to under 3k rpm.

#2 I personaly baught a cheap gpu video card heatsing. It is full copper 3' diameter and i think under 14 or 7 mm (i forget what the clearence is) I adapted the chipset a little to make it fit. This fan runs under 3k rpm while it is hooked up to the chipset connector on the mobo. The chipset temp never goes over low 60 degre F.

Antec sells 80mm case fans with speed switches on them. low, med and high. I got a cheap 120 mm fan and it was just barley quieter than a standard 80mm. Antec psu's also have fan controllers on them to regulate the fan speeds. They normaly run 1700 rpm through the psu (almost too slow).

The stock amd fans are also very loud, probably louder than the 80mm case fans (but i guess thats why you use cool and quiet)

To help determine where the noise is comming from, get a short piece of hose.5/8 fuel line or a piece of garden hose will work well. Hold the piece of hose up to your ear and the other end in different places in your case. This will let you know what is makeing the noise.

I know what you mean, my pc userd to be so loud i couldnt sleep in the same room as it was. it even bothered me while gameing.

You can also try pressing in gently on various parts of the case to see if it's a case resonance problem. Sometimes simply deflecting a section of the case by a very small amount can make resonance noise disappear completely.

As for fan 'turbulence' noise, you can also try the diagnostic of holding your hand or piece of cardboard about 0.5 to 1cm in front of a fan grill. This will change the air flow characteristics sufficiently to disrupt resonance at fan ports. If the noise changes or goes away, you've found at least one problem. Cutting your case may not be required. If this is the situation...post back.

Holy, it took me a while to get around to doing this lol. :blush:

So I finally opened up my tower today, and started listening around to find the cause for the noise.

+The CPU fan (stock) runs pretty quiet. (~3600 according to Cool'n'Quiet,staying at 40 C, idle)
+The NB fan runs pretty quiet. (~3200 RPM - a lot lower than micro's so I guess this issue may have been addressed by the time I got my mobo which was actually September 2005.)
+PSU is quiet.
+Hard drive isn't bad (Seagate Barracuda actually, I thought it was a WD)

-The stock GPU fan is fairly loud and contributes a slightly higher pitched noise
-The 80 mm case fan is really loud.

Resonance/vibration doesn't seem to be a problem although I'll take a closer look at this still. Could air flow through the grates create noise since it is being impeded slightly? (The grate itself isn't vibrating)

So without a doubt, an alternative case fan would be a good idea since the current one is basically as loud at the GPU fan but would be easier to switch out. I'll look aroud myself but does anyone have any suggestions for a good fan that would be considerably quieter?Preferably around $20 and adjustable speeds would be nice.I'll take a look at the Antec ones micro suggested.

Also any ideas of how to approach replacing the 6600GT heatsink/fan with something a bit quieter (and relatively cheap). I've never messed around with any hardware like that so keep that in mind ;)

Thanks for all the help and ideas so far. It's much appreciated.

if it is not the fans, another problem can be your subwoofer if the volume (knob on subwoofer or speaker) is set too high....generates a humming noise.

I had a 2:1 Altec Lansing speakers...had to keep the bass volume to low, otherwise; the woofer would hum

I dont know which cooler to replace that gpu one with, but i would bet that if you get some mineral oil (sewing machine oil, preferably not 3 in 1 vegtable oil) And put a drop on the bearings of the fan, i bet it will make a big difference. Sure it will attract dirt, but im sure due to the age of the card it will help.

Same here. The chipset fan "groans" on boot until a about 10 seconds in (I think low RPM). If it did it all the time, I would be RMA'ing it.


Case fans, just buy a fan and replace it. dB ratings aren't always accurate but I would never put a fan in a computer that's over 30 dB.

Grating on cases often doesn't add very much noise. What usually makes fans loud is high amperage (and thus, high RPMs) and small diameters.

I have 3 of these (2 intake, 1 exhaust) and my computer would definitely be described as a quiet beast.

As for the videocard, i'd try either:

http://www.newegg.com/Product/Product.aspx?Item=N82E16835118117

I used to have an Arctic Cooling heatsink on my 2 6800GT's and they were silent and cool.

Good luck!

I took a look at the Zalman GPU cooler and it's looking good. Only problem is, tigerdirect.ca doesn't carry the all copper version but the Al-Cu. Would I be better off finding an alternative all copper heatsink or will the hybrid be enough (preferably on silent mode, although 29 dBa on regular isn't too bad).

As for case fan, http://www.tigerdirect.ca/applications/searchtools/item-detail...No=2503508 is probably what I'm gonna go with. I'll have much more air flow from it at 45 CFM while staying a very quiet 17 dBa.

EDIT: As long as the Zalman Al-Cu works as well as the stock heatsink in terms of cooling, I'll be content.

EDIT 2: Some other Canadian online shops offer more products so I'll dig around a bit

Hey guys, thanks for all the help and suggestions. I ordered the parts Friday from NCIX.com, got them today (we had a long weekend) so delivery was super fast. Really quiet now.
