I researched the Cougars recently.

There have been quiet a few reports of the squealing issue with these fans.

They are also said to be pretty good for cooling CPU heatsinks.

I have a pair of them running on my Antec Kuhler 920 mounted vertically and have experienced no squealing. They cool as well as the stock fans while being quieter in almost all situations. Though they may require a touch more RPM to move as much air as the Antec fans, they reach that RPM with less noise.

been running mine for about 3 months now and no squeal at all. I have 4 and they are mounted horizontal and vertical. They all are just fine.
