GX280 - is it the motherboard?

Hi - I have a Dell GX280 which has the loud fan issue..

I have replaced and upgraded the original heatsink w4254 to the G8113 and replaced the original fan w/ same model.

The fan is still running at a high speed - w/an above normal noise...

Do you have any suggestions on how to fix this... could it the motherboard? if so - do you know what dell replaced the problem boards w? (i.e. model #) I also did a bios flash today A03 to A07... :-0 but the fan is still not very quiet... your suggestions would be greatly appreciated.

thanks!

Hello, I've got a Dell Optiplex GX280 series desktop pc which has refused to boot up. Instead it shows an error saying "Alert! chipset heat sink not detected system halted! Would appreciate your...


Both your CPU and chipset have heatsinks to dissipate the heat they generate.
Over times, the heatsink compound between these components and the heatsinks
may dry up and no longer conducts heat efficiently. Your system on power up,
detects excessive heat from the chipset and if allowed to continue on, will burn
itself up. To protect it, your system shuts itself down.
Open up your case and inspect the chipset. Make sure the fan (if any) is running.
If it is, you may have to remove the heatsink (normally clipped on to the chipset)
and remove the old compound and apply a fresh new layer of heatsink grease.
While you are at it, also replace the heatsink compound of your CPU.

Hd keeps rebooting. I swapped drives, battery, memory and still the same so it must be something with the motherboard. Any suggestion. It's a Dell Optiplex GX280 desktop


It could also be the processor, either its overheating or it has simply packed up first check that the heatsink above it has been correctly installed and is resting directly on top of the processor and that the fan on the heatsink is functioning. If that doesnt work then replace the processor completely.

I have a dell optiplex gx280 which seems to have a racing fan problem. sounds pretty loud, and varies. any ideas?


The fan bearings may be going bad. Variable speeds are normal as the fan adjusts to the cooling requirements.

Over heating


No thermal grease or old dry thermal grease and a dust and debris filled heatsink is your most likely cause of this problem. Dell isn't very overclocker friendly...it is more likely a lack of maintenance in blowing the dust out of the case on a regular basis. Take the case panels off and use dry compressed air to blow the system out and clean it thoroughly. The heatsink needs to be removed and the hold down latch on the processor needs to be removed and the heatsink and processor need to be wiped clean and a new thin layer of thermal grease applied to the processor. Put the system back together and fire it up.

Optiplex gx280 processor upgrade


eykraus,
I have some experience in upgrading your Dell.
If this gx280 was my computer and want to upgrade I'll only go to 3.0 but you need to upgrade you bios to support the new upgrade. You could also upgrade the memory as well. Put the power supply you have in so you can conserve.

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.

In my Dell Optiplex GX280, the processor fan was not start properly its run moderate speed for continuously but within 10 mins the pc shutdown automatically, after turn on the error show thermal heat...


Sounds like improper contact with the cpu and heatsink. If the fan runs...it runs and it'll do it's job but if the contact isn't proper, it'll overheat. These are older machines and the thermal paste that Dell uses turns to power after hundreds of power cycles. Buy some cheap silicon based thermal paste, clean off the cpu and heatsink with some 90% ir greater iso alcohol and apply a small rice grain sized drop of paste on the cpu. When you install the heatsink, give it a couple of twisted to spread the paste out.

Should be good to go.

DELL GX 280 CPU PROBLEMS


100% motherboard issue guys. The dude above that said flash the new bios should realize that when you CANNOT post a machine you CANNOT flash the bios unless the bios chip is removable and you have another machine to flash it with. The only fix for this is a new motherboard.
