Loud "jet engine taking off" type sound

I have a Dell GX270 desktop that makes a sound like a jet engine ready to take off. I changed the power supply but that didn't help. Has anyone else had this problem?

    I disconnected the fan plug from motherboard and the noise is gone now. I usually keep my computer turned on all the time. Should I just buy a new fan?

Mine also rattles like a snake, and it can start right in the middle of the night so that ive 2 stop and just shut it down.(its always on) I just blow the compact fan case using compressed air, lots of fine grainy dust come out then its silent. i believe if capacitors are leaking ( thats less severe than if they totally go off and powerlight is amber) coz my board was replaced by guarrantee several years ago coz of that. but by then i was a kid and didnt know about cooling the computer. i stuffed books beside it and it just got coocked after afew years. ok getting a brand new fan for GX270 might be an issue (tis nolonger being actively producd i guess) so focus more on blowing dust off the machine. i guess it has a resistor same as the CPU fan that increases current on high temperature and yr capacitors get abit less accurate at high temp, leading to the rpm variations.mysteriously mine has become completely silent when i googled 'noisy GX270 optiplex power supply fan' ope it never goes back 2 its rattles again!
A great machine nevertheless! I stick with Dell.

Check the capacitors on the motherboard. The GX 270 suffers from bulging/leaking capacitors which can cause all sorts of porblems including the CPU fan racing.

If you changed out the power supply then the only other device that could be making that noise is your CPU cooling fan. To be sure, open the case and disconnect the CPU cooling fan plug from the motherbrd (MAKE SURE POWER IS OFF) and see if the noise stops. Don’t worry about the “Fan Failure Error” when you turn on the computer. Just hit F1 to continue. Don’t leave the computer running without the fan plugged in longer then necessary. After tying this procedure, please contact me for further diagnosis.

Dell GX270 has D amber light


An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard.
Remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Gx270 tower mother board amber LED solid on


If the fan is not spinning this can be the issue ...but it can also be the motherboard itself ..if you have the possibility try to change the fan ..cause if it fails to start the computer will also fail cause the cpu it will shut down the system instantly if it has no cooler working ..(gets to the shut down temperature in one sec or so ) If it seams that it is trying to start ..but , like I said , it shuts down ..just try to change the fan ...but it may be a issue with the power supply or the motherboard as well...

I plug power cord and nothing happen no light is blink means dump , i shutdown 2 days back pls advvise what to do'??


Sounds like a bad power supply or possibly bad mother board. Make sure the fan in the power supply comes on when you plug it in. Also if, you are game, look inside the PC and make sure the power supply is plugged into the mother board and not loose.

Something in my tower sounds like a plane getting ready to take off. What is it?


There's probably something touching the cpu or case fan. I'd take it outside and clean the tower out with two cans of compressed air. Once you've got it clean out visually inspect the fans to make sure they are clear of all obstructions.

Not turning on there's only beep sound coming out


Bad power supply, these are case specific but if you cut a hole in the back you can make a standard power supply fit in its place. Dell used 150-250 power supplies and they go bad regularly.

Dell optiplex gx270 making a loud clicking noise. I think it's my harddrive going bad. Use to shut down when it started doing it, and now will make loud clicking noise and then stops..system runs a little...


Yes, your hard drive is going bad but before concluding that your hdd is already bad do this first download hard disk sentinel and install it on your pc.

after you have downloaded and install the program run a series of test on it. then if you find that the hard drive is already faulty then its about time to replace it

Will a dell gx280 motherboard fit into a gx260 (dell) case?


If it is a slim gx260 case, it might not. If it is the wide case, it will, but the two motherboards have different power supplies. You will need to use a gx280 power supply to power it on. However, you can use a gx270 motherboard in a gx260 case without changing the power supply.


Hope this helps!
