Noiseblocker BlackSilent Pro Fan PC-P - 80mm

I bought this to replace the ridiculously loud fan in my Silverstone SX600-G PSU that was rattling away. I needed a slim 80mm fan that was 17mm or below in thickness and this fit the bill.Wired to a PWM fan controller the lowest RPM it could achieve was 900RPM and it's deathly silent until around 1700RPM. Obviously at full pelt its a lot more noticeable but it's perfect for most real world applications

I needed these fans to go in the top of my Corsair 650D to replace the default 200mm that comes with the case.I purchased two of these fans and have been very impressed with them. I read good things about them elsewhere on the internet before purchasing them, and have not been disappointed. They are quiet and move a lot of air. I have them attached to a fan controller, so they spend a lot of time not doing anything, but when I turn them on, the temperature in my pc case falls quickly and stays at a lower temperature (good for gaming sessions!).If I ever had a need to purchase more 140mm fans, I'd definitively consider these again.

Very quiet, bought it for a mini atx case since I was getting high case temps, works like a charm.

The black silent pro fan is excellent quality, moves a decent amount of air and above all is reasonably cost. You can get quieter but you have to pay a good bit more.

So silent

very well fan:-)
