I have an old Compaq ML350.  The system fan makes a terrible noise and i would like to unplug it.  Unfortunitly if i do unplug it, i get the following error:

Critical Fan Failure Detected - System Shutting down.

Is there anyway to bypass this POST check?

you should be able to do this in the BIOS. However  dont recomend leaving the fan out as the server will overheat. Try dusting it off and if it still makes alot of noise you will need to buy a new one.

Nope, no way to bypass. I doubt you can even get into BIOS before it shuts down.

If you install the PRoliant Support Pack for your particular OS it ought to quiten it down a bit since the older ones had the fan speed control in the stsstem health driver.

Hi,

The motherboard has a sensor that detects how much power the fan is drawing. If you blow on the fan at startup, you might fool the sensor but when you stop blowing, the fan will stop turning and your CPU will overheat.

It’s extremely cheap to put a thermistor on a CPU made in VLSI, and the CPU has a overheating sensor, and that’s why your laptop might shut down a short time later after it has booted up. Your fan is not working and so the CPU shuts down.

So in short replace the fan or else repair it if you can.

Hi speedfox6

Thanks for your reply.  I have on many occasions looked in the BIOS in hope that i will find an option for “turn this stupid fan off” setting but to no avail.  This fan is only a system fan and the processor is an old P3 processor.  I don’t think heat will be a big issue

As other have said, it is not possible to turn it off.

Is the fan noisy with "air noise" or does it sound like the bearings have gone ?

If it is just air noise, then taking the fan out of it cage an cleaning it can work wonders, if it is the bearings,then you will need a new fan. depending on the model, it might have speed as well as current sensing, but you should be able to get something on ebay...
