I recently got a new heatsink and fan assebmly for my computer, and my computer does not detect the nw fan. It has the same number of wires, and I put it in the only place for a fan on my motherboard. The fan works fine, but the comptuer just does not see it. Any ideas on how not to wear out the "F1" key? let me know. thanks

Hi,

Please list your system specs especially what mobo you have.
be more specific what is telling you that it does not detect the fan is it some sort of software or won't the computer boot because it thinks the fan is not working?

I know you said you connected the fan to the only place on the mobo (motherboard) but is it the same place the old fan was connected to and did it detect the old fan?

It tells me that it cannot detect the fan right before it starts windows, and I have to push the "F1" key to continue. And yes, I connected it to the same place that the old fan was connected to. Well, that's all I can think of to tell you. If you need to know anymore, I would be more than happy to provide info. Thanks for your time!

Ok now I see its a dell and I know what you mean by keeping the mobo and manual for it a secret.
I ain't gunna be much help here but the bios ain't detecting the fan for some odd reason who knows why its a dell. but maybe you could look around in bios for something like cpu fan detect and turn it off, I doubt it but thats all I can think of at the moment.

sorry coun't be more help

Did you get the fan through Dell?

Dell is known for only working with their products and only their products.

Example: Dell printers, you can only use Dell ink catridges with it. This leaves out the great sales of HP or Epson ink cartridges at the local Staples.

I would imagine they would want you to only use their products. I would not be
surprised if they wired their fan connectors backwards to cause confusion if
a non-dell replacement part is introduced to the system.

Actually this is the second replacement fan. The first replacement was not from dell, and I had no problem with it, and this one is not from dell either. Dell is the kind of company to do that sort of thing though. Good thought.
