Plugged in the two fans today to see how the airflow compared to the stock meanwell fan, and it was pathetic. Both fans together provide significantly less airflow than the stock fan. Only benefit is that they are virtually silent. But, since cooling is ultra important here, I will be returning the fans and retaining the stock fan for now.
Stock fan is 33.1 CFM @ 45 dbA, 6800 RPM, 60mm*60mm*25mm.
The two replacement fans were
- Arctic F9, 43 CFM @ 23.5 dbA, 1800 RPM, 92mm*92mm*25mm.
- Noctua NF-A6x25 FLX, 17.18 CFM @ 19.3 dbA, 3000 RPM, 60mm*60mm*25mm
I was expecting the Noctua to have less airflow, but the Arctic wasn't much better. If the Noctua's 17.18 CFM and the stock fan's 33.1 CFM are both accurate, I would rate the Arctic to be somewhere between 20 and 22 CFM.
Next up is to find a fan that has at least 40CFM with a noise rating of under 40 dbA in the 60mm*60mm*25mm size to replace the stock one. That is, if such a thing exists. From some brief researching most 40 CFM 60mm fans are over 45 dbA, and most <40 dbA 60mm fans are 30 CFM or less.
