It wasn't too many years ago that buying a 'heatsink / fan' for a CPU meant trotting down to the local computer store and picking up a small heatsink (typically painted black) with a tiny 486 / video card fan mounted above it. These unassuming coolers shipped in plain gray and white boxes with the manufacturer name (or names) hidden in an odd corner. They were not sexy, they were not stylish, and they most certainly were not 'performance coolers'; these old workhorses were designed for functionality, not flair.
