Hi
Generally Dells run very quietly, so there are three possible problems here.
The first is that excessive noise can be caused by the fans having to run faster than usual to keep the temperature down. In this case you need to check and make sure that all the airways and interior of the computer are clean and clear of dust, which can build up in such a way as to seriously obstruct airflow. If this doesn't help there are normally at least 2 fans in the computer, one for the CPU chip and the other in the Power Supply. If it definitely one of these the only real way to cure it is to replace whichever is causing the problem.
You can download a very comprehensive manual for the GX280 here:
Product Support Dell US

by clicking on the "Users' Guide" link. This will download a pdf file which can be saved to your drive for future reference. The manual contains detailed instructions for these types of things, easily accessed by an interactive menu system.
Since this is quite an elderly system, you may find, that after pricing any replacements necessary to cure the noise, it makes more economic sense to put the cash towards a more up-to-date system.
Hope this is helpful, if so would you please register that with Fixya
Cheers

SOURCE: Dell Optiplex GX280 boot problem

I just repaired two Gateway systems with similar behavior (turn on power, fan runs at full speed, no boot), and both needed replacement system boards. (These were a different model, but the symptoms are typical of a dead system board.) I got the boards from a company called Blue Raven Technology (www.blueraven.com).

Before deciding the main board is bad, try another power supply to make sure that's not the problem. Also you might try clearing the CMOS memory on the system board (either by moving a jumper usually found near the backup battery, or by removing the battery itself). Sometimes corrupted CMOS data will keep the system from booting.

Dose not boost and fan is high speed


The Thermal Paste in-between the Processor, and finned Heatsink that sits on it; has dried up.

THOROUGHLY clean top of Processor, and bottom of Heatsink.
PROPERLY apply fresh, new Thermal Paste.

FOLLOW Anti-Static Procedures.

Dell optiplex GX280 PC when power on system no noise with fan after one hour making loud noise . I changed the CPU fan , also same noise, and applied heat sink paste to CPU and heat sink same noise....


There probably is another fan, located inside the power-supply, that is making all the noise.

Borrow a stethoscope from a nurse or doctor, and listen to the noise, to pinpoint "where" on the computer that is the origin of the noise.

My pc gx280 is not display fan and pclight on fan is high noise


Could be a possible videocard issue.
Try connecting a working videocard in one of the expansion ports.

A high fan noise could also mean a failing power supply. If you have a spare power supply I would also suggest installing the spare one

Updrading power supply of Dell Optiplex GX280 Small Desktop.


Hi there.
No, 400Watts will not affect your computers performance, it just means that you will be able to add more peripheral devices to your PC, for example, an external or internal hard drive or more USB devices.
Make sure you get the power supply from Dell themselves as you will find it difficult to install a standard PSU (power supply unit).

Good luck and thanks for using Fixya!!!
