hello all, I have a small :thumbsup: problem with a machine I'm resurecting for my son to use. The problem is the fan has failed, and I have another fan, actually many others, It has a 3 pin connector on the mother board 12v 12v GND. I can hook up the fan and it works, well the fan works however even before I can get to the part of POST where I can enter setup it stops and says " WARNING: Fan Failure. System will be shutdown." So i'm guessing I need to find out where/how it checks for the fan prescence, and fool it. I have also downloaded and looked through the manual's from dell, they are located -> http://support.dell.com/support/edocs/systems/dfuj/ .

And if you are wondering why a computer so old, my son is 3, I just need to get past POST so i can put in 98 and some old kids games.

You are talking about the fan in the back of the case & not on the CPU ?

The fan has to run at a specific RPM to get rid of the error message.
Unfortunatly Dell used fans that ran at a non standard RPM .
There is a way to trick it by connecting 2 of the wires together
It's been so long since I've done one I can't remember the exact 2 wires but I'll see if I can find out with a search.

I've done a lot of searching & can't find the old article on the fan error workaround.

That's about as good as it gets when it comes to neccessary parts to make a older unit work.
