ok, i have 5 fans in my syste.
2 x 80mm in the PSU(checked reviews, very VERY quite PSU)
1 HD 4850 ICE q4 RUNING at ~500 rpm on idle
and 2 more 92mm fans runin,g 1 for cpu and the other one as an exhasut fan in the bakc of the inspiron 530 case. one of them is driving me crazy, one is runing at ~1000 rpm and the other one is runing at ~1600 rpm and both are on idle!!
is there a way to fix it? a way to check which fan is causing all this loud humming noise?
the warrenty expired so no dell help here.

when im just browsing the net at night and that humming noise is the only thing thats making a noise , it just drive me crazy. i already took the fans out and cleaned them, so dust isnt causing the issue.


can you tell me how can i check and speedfan doesnt controll my fans AT ALL!

Run the system without the exhaust fan to find out which fan is making the noise, then replace that fan with a bigger one (the bigger the fan, the less rpm it needs to displace a certain amount of air, hence less noise.)

Once you figure out which fan is makeing so much noise... u can oil it up, to fix it...
to do that, take it out, on one side there will be a sticker of some sort, "Brand name" or something... Peel it off carefully, and save that sticker. then some motors have a rubber seal, and some dont... if u have some 3in1 oil, or simular motor oil. (i think its 20 weight..) u want it to be some what thin oil... not thick... and just a drop of oil in the motor, and move it around and up and down, to get the oil down in the shaft...

now if it does not want to get in the shaft... u can take the motor apart. there is a white plastic washer, that is cut on one side, this will pop out, with small tools, like tweasers and screw driver, and such... (But be carful, it can crack and break.) if this can be removed, the fan will come out of shaft... and then put oil on the other side, where the oil could not reach too... then put back to gether... put sticker back on... and fire it up... this should fix it...

I'v owned 80mm fans for 18 years, and been oil'ing them up, and never had a fan go bad. (as lone as, every 2 years, its taken care of)...

good luck...

Would be quicker just to replace the case with something like antec 300 / 900

With the power off, stick a pencil into one of the fans to prevent it from turning and then turn on the power. Repeat until you find out which one is causing the noise.

Rather than best buy, look for on the net for some quiet fans. I think Noctua specialise in it don't they?

ok. the fan turned out to be the cpu fan, an 80mm not a 92mm. even after putting the oil in, its still kinda noisy, but i gotta wait to see what happens next. thanks!
