Summary: Like the Review by PapaPopup - I couldn't find only a 50mm fan anywhere, I didn't need the heat sink. I just screwed the fan off and screwed it to the old heat sink since the heatsink had a temperature wires attach to it. Plenty of air movement, almost silent, and the price was right.
Summary: This thing is a piece of garbage (literally, I just threw it away)! The entire heatsink is made of aluminum, no copper base to adequately transfer heat up through the fins. The fan itself is not much larger than a half dollar and, though it is quiet, does not have adequate airflow.
Summary: I couldn't find only a 50mm fan anywhere, I didn't need the heat sink. I just screwed the fan off and screwed it to the old heat sink since the sink was sorta welded to the cpu. Plenty of air movement, almost silent, and the price was right. This will keep the old machine running a few more years.
Summary: The clip is made out of metal so thin that it bent badly while I was trying to mount it. It also broke or sliced off one of the fingers on the side of my mount because it was so thin. I ended up having to use the clip from another old heat sink.
Summary: Purchased to replace old noisy fan in 10-year-old computer. Intel Celeron 1.2 Ghz. Was going to use old heat sink, which was welded to cpu plate with dried heat sink paste, but then it popped off. Had to use old clip to fasten new heat sink to cpu. Powered up immediately.
Summary: Cheap and quiet. Harder to take off the old fan than put on this new one. I was just trying to keep my dinosaur of a computer running but it had recently broken a fan blade. In a matter of minutes I went from noisy to ahhhhhh
