The Corsair ones are super loud swarm of bees is about right lol. I was the proud owner of 11 of them, Cougar fans are a little quieter, proud owner of 5 of them.
Them are a good option also for them rads had 11 of them, they are alot quieter than the corsair ones. Prolly same noise as cougars.
These are the rads they...
