I just swapped the fan in one of my 192's because the original one had started clicking and I was worried about imminent failure. I used a Noctua NF-R8 redux 1800 which is 53.3 m3/h or 31.37 CFM and max RPM 1800 because it was similar to the Silenx one others have used, 31.37 vs 32 CFM. The original Cofan K0825A specs say it was a 44CFM @ 3100RPM fan, I looked it up after I pulled it from the interface. I can feel that the Noctua doesn't push as much air as the Cofan when I put it side by side with my other 192's, yet on another thread somebody posted that Digi had said the stock fan was 34 CFM? Maybe they changed specs?

Is there anybody here who has had a Noctua NF-R8 installed for any length of time that is still running fine?

Do people who have put in the Silenx fan that is rated for 32 CFM notice that it pushes less air than the stock Cofan?
