Today I reached the limit of my patience with a CPU fan that had become whiny over the years. It sounded like a 1-pound mosquito, and the whine varied in pitch with the workload on the CPU, making it even more irritating.
Air blowing and vacuuming a couple of times had reduced the volume, but it always returned to distracting levels after a day or two.
The new CPU fan above the old fan. The new one is huge, stands “sideways” atop the CPU like a mini-skyscraper, and has a different mounting system from the old fan. When I was buying it, the guy asked “are you sure you have a big case?” I can see why he asked :-).
After struggling with instructions for nearly two hours (!), I laid out all the parts that came with the new fan, checked my parts bag from the original motherboard, and put together my own installation solution.
The new fan nearly touches the clear side of the tower.
Ah, the sounds of silence! The computer is now barely audible, knock on wood…
