Have you got the latest bios firmware already installed? That's a good place to start with a problem like this. Otherwise there is a special 3rd Party app that might be able to control your fan thru software control. Either way start with the bios update first and post back if it doesn't work.

Best of Luck!

Dell Optiplex GX280 has very high processor fan noise.


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

As soon as I install the lan drivers on my gx280 it goes off and the cpu fan speeds up to full speed, without these drivers it would work fine all day without internet connection of course.


Try running diagnostics on yourcomputer to see if you have a hardware problem. You should have a CD that camewith the computer that has "Diagnostics and Utilities" listed undercontents. Boot form this CD and run the extended diagnostics.
If you don't have the CD you can go to www.support.dell.com and select "Drivers and Downloads". Enterthe "service tag" (serial number) of the computer. You can then download"Diagnostics" .
To boot from a CD disk, power on your computer and tap the key to bringyou to the "One time boot menu". Insert the CD into the top CD/DVD drive andthen select "Boot from CD/DVD" and hit key. Select the "Runthe 32 Bit Dell Diagnostics.

If all tests pass then reload OS ( Operating Software ).

We have around 30 units of DELL Optiplex GX280 having mother board failure. It was more then 3 years old already. Once the turbo fan become noisy then it will gone dead.


May be serious. See if the power light goes amber after power up. I had (have - still siting in my basement) one that did same. Power up, fans sound like 747 taking off. Power light goes and stays amber. This is USUALLY caused by bad capacitors on the mother board. Known GX280 problem going back. If you look on the motherboard, the capacitors should have flat tops and not leaking. If the are rounded or leaking, the MB has probably gone bad.

I obviously can not be 100% sure about this as the unit is not here.

You can google "gx280 solid amber light loud fan" and see the issues. Here is one such link.

The fan of dell gx280 producing a loud sound, how I fix it ?


Sometimes something is stuck in the grill and the blades keep touching it, other times the bearings have worn down and the fan or entire power supply needs replacing.  I used to hit my PCs noisy fan with the palm of my hand and the loud noise stopped!

I need dell gx280 vista drivers

You may have to open the system and see if there are manufacturers names and model numbers for some of the devices you are seeking drivers for. Most of this hardware has not been supported by Dell to use with Vista or Windows 7, however, if you find drivers for windows 7, it uses the same cire as Vista so they may work.

Dell Optiplex GX280 - On power ON , no Fan movement no display


Confirm no leaking or bulging capacitors on your mothboard.
refer to here
http://en.wikipedia.org/wiki/Capacitor_plague

As this was a common problem with the GX280.
If found, you will need to replace the capacitors.

The other check is to make sure the heatsink is fitted correctly, perhaps reaply the thermal paste if you have any. I know that high temps would switch the GX280 off.

Same problem... orange power light, fan starts slow and builds up to very high speed.
I removed my video card and SIMMs --> it beeped on boot and the fan did not speed up.
Put one SIMM back in --> booted fine, pressed F2 to view BIOS. Memory reported fine.
Put all SIMMs back in --> all fine now.
