Ah, thanks & Sorry Peter, here are the Fan Specs

No I wasn't. It's a genuine fan, that snaps into the motherboard, and is really hard to pull loose, has to come straight up, although you can pull one end up at a time.

Blame it on Pentium, they made it. ;)

Edit: I hunted up the box and old fan, and it says:
Intel Pentium 4 Processors. This Intel Pentium 4 Processor includes a high quality fan heatsink for successful integration. This processor is intended to be professionally installed.

Hmmm wonder if they deliberately made it where it wouldn't be okay if NOT professionally installed. I assume they mean by a licensed hardware technician?

Anyway, the fan is weird, it has little black legs of a sort, that come down almost to the bottom, but not quite. The motherboard, which is a Pentium D845PESV, comes with a Retention Mechanism, which basically looks like a frame around the Processor. (You fasten it to the motherboard). It has a little low square wall or frame, with four little raised end squares with slots in them on each corner, around the CPU. The bottom part of the "frame" is higher than the CPU slot, and the clips go into the little squares or something like that. (Kinda looks like a tower with points on each corner, only they are square points). The upshot of this arrangement, is it completely smothers the CPU, you can't get to it or to the lever to release it, from underneath because of the frame wall, which is about maybe half inch high, (I'm guessing, cause that is still inside the case), and you have to install the fan straight down, one end at a time, and remove it the same way.

The fan itself has numbers all over the top, but I don't know if they would help in identifying it or bringing up a picture, but wait, I found something else. The processor manual refers to it as the: P4 Socket Processor Fan. And it says they also make screw-on types Clip On Types, and Passive Clip-On types. But none of those use the retention mechanism I described above, so we have the P4 one.

I can see where you would be able to twist a screw-on type fan though, however,this isn't what we had. So I'm sorry if Peter thought I was putting him on, I was not.

Anyway, that's all the information I seem to be able to find on the fan.

Edit: Actually, I managed to find a picture of it on the net as well. :)
Here is the fan itself:

And this link gives you all sorts of views of both the retention mechanism and the fan itself, (scroll down till you see the images).

Edit: corrected the description
Edit: added links and corrected about retention mechanism.
Edit: Forgot to change subject line last night, so I did that today

Post #176,920 by altmann 9/29/04 1:37:14 AM Reply	I Concur. No twisting Allowed You can't twist off a stock Pentium 4 fan/heatsink assembly. The 4 posted bracket permanently attached to the motherboard fits right up against the sides of the rectangular heat sink. It can also be a bear to remove after the fact, as I recently found when switching mine to a quieter Zalman model. I nearly had one of my all too frequent Hulk moments. -- Chris Altmann
