1) When you say "it's quiet", can you relate it's noise level to other hardware in your system, so that we have some reference to compare it to?
It's the loudest component in my system, but not by much. The sound it makes is gentle white noise. I've got it in a SLK3700AMB case with a S12-330 PSU. It's holding a WD3200JD drive.
The SLK3700AMB's drive bay door makes it even quieter, of course, but I'm feeling a bit guilty about the door blocking the mobile rack's ventilation.
When I tried to measure the temperature of the WD3200JD drive it's holding, hddtemp (Linux) reported "known drive, but it doesn't have a temperature sensor."
2) I assume that the fan only runs when a drive caddy is in place in the tray. Is that correct?
The fan runs when the front power button is pushed in.
On one hand the fan looks like 60-80mm to me, but looking at the pic it seems that the fan does nothing but circulates the air inside the enclosure
It takes the air from inside the enclosure and blows it right back in...
The fan is a 80mm YLTC DFS801012L
with the following specs:
Frame size: 80x80x10
Special functions: Temp. Ctrl., Auto Start, Alarm, LED, PWM
Bearing Type: S
Noise db(A): 26.51
You may be right about the circulation. It has front and rear air vents but I can't feel air moving at either of them.
