Trying to find a replacement for my much beloved Noctua NF-F12s to match a build I am planning. The Cougar fans come up a lot and match my colors for my planed build perfectly. The temp numbers look great compared to Noctua fans
Both numbers are after about an hour of Prime95 on my i7 950 with a Thermaltake Water 2.0 Extreme. So going by these numbers the Cougars look great and they are until you hear them. The Cougars have a high pitched hum to them compared to the low rumble of the Noctuas and the sound its self is louder. Even at idle they have this high pitched hum. So they end up being louder at a more annoying frequency. Granted they move more air but I have little to no tolerance for computer noise.
I'm thinking of trying the Noiseblocker NB-eLoop B12-PS, they are more expensive then the Cougars but I'm willing to pay for performance. They also add white to the mix in my build witch throws off my color scheme a bit but if I switch from orange pastel to white pastel coolant to tie in the fans it should work. Might even be better this way being the orange pastel is a poor match for Gigabyte Orange anyways. I'll just match up the orange in the mobo to orange sleeved cables.
The final build will be using Alphacool UT60 radiators so we are talking about a low fin count per inch. Besides the NB what other fans should I check out? Keeping in mind I would like to stay with PWM fans to let my mobo do the fan speed adjusting as needed for ease of use.
I know GTs come up a lot but they are not PWM and they will be impossible to fit into my planned builds color scheme. So black and white or all black fans please.
