Intel Mac Mini replacement fan

Interesting question. I would check with your part supplier on this. It is possible that the fan you got is not for your mini model. It could be one of two things, either your supplier has provided you the incorrect fan (twice), or they gave you a broken fan (twice). Neither seem very likely, but with your troubleshooting, thats what your left with. Hope this helps.

It seems that there is not enough power to the fan to give it the initial extra boost it needs. Fans take more to get them spinning than to keep them spinning. The chirping noise is indicative of a fan that was never initially lubricated or has lost the lubrication. You would want to be very careful, but you could certainly try a little white silicone grease on the fan shaft where it inserts into the fan case. No lube would also explain why you need to "jump start" the fan. You can usually get the white silicone grease for electronics at an electronic supply store like Radio Shack. No guarantee, but it's worth checking into.
