GX-280 fan problem

Question

I have a customer with a GX-280 mini tower case that is having fan problems.  The computer sits in a cabinet that is pretty small and not much airflow.  The rear fan is really ramping up and it kind of sounds like a jet engine.  I think that the processor is telling the fan to blow harder because it is hot and needs more air.  I think that this is working as planned but I am unsure of this.    Is the fan heat sensitive?   Is there any way to quiet down the pc?   Thanks,   Brad Wilson

bhgewilson, Thank you for using the Dell Community Forum. The system is overheating and cannot get enough air flow. Try sitting the system on the floor or on the desk instead of inside a cabinet.

To quiet down the PC you need to either do less work on the CPU and/or lower the case temp. Besides moving it out of a cabinet, you can try adding a PCI slot fan and see if that helps.

Its always amusing to me that people abuse computers and expect them to operate normally or better than normal.

If you put a human being into a dark hot box without much air you would find that they too tend to slow down and die due to overheating and lack of oxygen.

Unless the cabinet has lower and upper free air vents in a room that is 60 degrees all year round you are not going to be able to put a computer in there and have it run quietly and reliably.

If you want silent out of the way computers you must go to long distance remote liquid cooling. That way with no fans in the room you dont hear anything.

Not all GX 280 fan problems are related to being in an enclosed space. Have over 50 GX 280's in this office. Latest fan incident (loud and vigorous fan) was resolved by a 'restart'. Seems (to me) to be pointing to software that was running at the time, or a memory cache that was not dumped until restarting. The other two incidents were after a power loss, and attempted restarts. One was resolved by swapping out a SK-3106 (card reader) keyboard for an RT7D60 (card reader) keyboard, and the other by motherboard replacement.

Solution is hyper thread in the Bios. WHAT EVER IT IS SET TO THE OPPOSITE. If on the off

Go to performance. Click on Hyper threading and see
whether it is set to on or off. We tested three machines. All had the Hyper threading set in the off
position. The first two hyper threading was changed at the boot process.
The third we waited till the fan was roaring changed the fan and it is
purring like a kitten
