I got a pair of Noctua NF-P12 back in August and I finally got the time to install them into the Ncase. The reason I get the two fans was that the Corsair SP120 cooling the 980Ti is a little on the noisy side when gaming so I was thinking how can I reduce the noise. I always hear how good Noctua fans are so this is probably the good time to get them.
I made the mistake buying the P12 instead of the F12 thinking that like Corsair, P stands for Pressure. It’s not, it is just Premium for Noctua and F means Focus which is the one I really need. The P12 also runs at just 1300RPM instead of 1500RPM on the F12. Anyway, they are considered slow compared to Corsair’s running at 2300RPM. Noctua 2000RPM fans are their Industrial line and they cost almost double.
Replacing the two fans inside my Ncase isn’t hard. With the spare SP120, I decided to use one as exhaust on the side panel, and the other one as a second fan on the NF-C14 CPU cooler. The later is a PITA to install without removing the cooler from the CPU. I used the original clip on its original 140mm fans. Since Corsair fans got this thick rubber screw hole, I have to use cable ties to hold the clip.
After putting everything back on, and flashing the 980Ti BIOS with new fan speeds, I went and run Furmark to see how the Noctua fans perform. One word: poor. At max RPM, which is around 1210RPM, the temp shoots right up to 81C without OC. It simply thermal throttle with OC even if I set the temperature limit to the maximun 91C. Things looks better in real world gaming test. I fired up The Division and with my CPU OC to 4.4GHz and 980Ti OC, the fans seems to be keeping the GPU temp around 80C.
Noise wise, at max RPM, they definitely sounds a lot more quiet than the Corsair pairs as they need to spin at around 1800RPM to get identical cooling performance. Since the SP120 is far more quiet than the stock reference 980Ti fan, the NF-P12 is almost like silent even at full speed. I wonder how does the Industrial F-12 at 2000RPM. For now it doesn’t thermal throttle, I’ll stick with the P12.
At the moment, I’m having five 120mm fans inside my little Ncase seems a bit absurd.
