Hey I have a Radiator from Cooler Master Hyper EVO 212 on my i7 5820K And i have used the fan that came whit the cooler, I was needed to buy 2 pair of coolers to get 2 fans for push pull config And it was working nicely! but now after 4/5 years of use those fans start to slowly dying. So my next move is to get 2 pairs of Noctua NF-F12 120mm PWM So my question is will that be a good choice? because Noctuna seems to aims for the silent variants, And not high RPM's? i7-5820k Stock speeds 3.3Mhz Hyper Evo 212 Evo Push pull config Tempratures idle low 38c / high 40c Ambient temp is 23c Load temp low 51c / high 60c Ambient temp 25c All answers is welcome! Thx!
