Summary: I was happy that it came with thermal grease and that I could flip the tab lock around. No issues on the first computer but my second one had the capacitor right in the way for where you pushed down on the lock.
Pros: Adjustable height on clip or reverse tab to avoid capacitors. Comes with small pouch of thermal grease. Quiet.
Cons: No instructions. Thermal grease not labeled well. I first thought it was a moisture packet.
Summary: I threw some Arctic Silver 5 on the processors instead of the thermal compound it came with.
Pros: I've had this cooler on two different socket 7 chips; a Cyrix 266 and an AMD k6-2 500 with both at stock speeds. It cooled them well and it will undoubtedly cool a AMD k6-III + (the fastest socket 7 processor ever made) when I can get my hands on one.
Cons: I don't plan on doing any overclocking with this but I doubt anyone would get very much out of such old chips anyway.
