I would like to build a quiet 10*hdds nas config, using:
-RSV-L4000 case
-2*supermicro CSE-M35T filled with 10*5K4000

For the hdd cooling, i'd like to remove the noisy 92mm San Ace from the M35Ts and use instead the case fanwall of 3*120mm filled with GT for their good static pressure and low noise.

I thought using AP-12 (800RPM) or AP-13 (1150RPM), but i don't know if that's enough to keep 10*5K4000 at a safe temperature (6.4W per drive in load, so 64W max).

Do you think i can get sufficient cooling with only three 800RPM fans ?
Or do i need AP-13, or AP-14, or even AP-15 ?
 
The problem with hard drives overheating isn't the fact that they run hot, it's the fact that they're often jammed close to each other, and have minimal room for airflow. Having just some airflow over them should significantly cool them down. Any 800-1200 RPM fan should do.
 
I know the AP-15 are nice but i don't want the best cooling/noise ratio, i want the minimal possible noise while keeping enough cooling for the hdd to remain safe at full load.
So if i can achieve this with some AP-12 or AP-13 this would be more interesting to me.
Also as i will use 9 of them, lower RPM/fan = lower global noise.

Indeed these cramped hotswap racks doesn't help, that's why i thought of the GT for their static pressure.

800RPM enough to you ?
