This may seem a crazy question, because the obvious answer would be temperature, but what controls the fan speed?
Firstly, my fan is set to "Smart fan". The unit is a F5-221
On average it is probably on low (nice and quiet) for about a total of 30 minutes each day. the rest of the time it is running at around 1500rpm.
Even in the middle of the night it is around 1500rpm. I'm old, so I get up
Here are some screenshots at 5 min intervals.
30 minutes later.....
I don't really want to force "Low speed", nor should I really need to.
Are speeds below 1500rpm unusual?

Re: What controls fan speed?
Today I will make an acoustic box to put the TNAS in.
The fan genuinely has a mind of its own. It peaked at 2100rpm.
This is with it set to "Low speed".

Re: What controls fan speed?
You could always fit a quieter fan.
Re: What controls fan speed?
Acoustic box is cheaper, cos I have the materials in my workshop, but I will check out the thread on a quieter fan.

Re: What controls fan speed?
Would a box not tend to increase temperatures?
Noctua fans are almost silent.

Re: What controls fan speed?
It should be ok.
The idea is to line the box with acoustic form, which deadens the sound.
Leaving a slit in the back top of the box, and a slit at front bottom, should allow for adequate air flow.
Not gonna go over the top and double skin the box.

Re: What controls fan speed?
Noctua NF-A8 PWM are quite reasonably priced on Newegg.
Approx AUD$51 for 2, which includes delivery. I think I paid AUD$32 each from a local store.
Just a shame that the fan speed control and detection don't work any more.

Re: What controls fan speed?
Actually, a direct question for Terra-Master:
Have you adhered PWM standards with the fans?
Or have you implemented your own method of controlling and detecting fan speeds?
