I currently have a Pentium 2 266mhz processor and a friend of mine got me a Pentium 2 450mhz processor from his school and I wanted to make the swap. Only problem is the new processor doesn't have the fan on it, so we were trying to get the fan and casing (don't know what else to call it) off the old processor to put on the new one. We got the fan off no problem, but we can't get the black casing off the old processor to put on the new one so that we can mount the fan onto the new processor. Any suggestions?

In case you don't know what I'm talking about "casing", I'll try to explain better. The old processor has a black "casing" as I call it all around the chip or whatever. But the new processor only has the black casing around half of it. The side where we mount the fan doesn't have the casing, only green area where chip or whatever is. Sorry if I'm not making great sense, I really don't know how else to explain it. Hopefully someone will know what I'm talking about and can help me out. Thanks.

I think I know what you mean because I own a Pentium2 350MHz and have it here just before me (upgraded to 733MHz Celeron a couple of months ago) because I kept it for replacement in the case that overclocking the Celeron by 500MHz (now 1232MHz) wasn't that good an idea!

My P2 also only has half a case (if you mean the piece of black plastic with "intel pentium II" on it) on the backside. The other side is fully covered by the haetsink that is as big as the whole slot1 card and that has a 5cm fans screwed on in the middel (just above the cpu). At every corner of the cpu is a metal pin that goes through heatsink, slot1 card and the plastic covering on the backside where they are fixes by two metal clamps who look like an E without the middle - (one clamp for two pins).

Sorry, I don't own a digital camera or I would send a picture but I think your heatsink isn't meant to fit on the faster pentium2.

Still I hope the description helped !!!
Good luck!
