Proper way of reducing fan speeds

[mrQQ]

Hello,

now that ReadyNAS OS 6 has smart fan speed control built in, what would be best way to reduce fan speeds at the cost of increased system temp? Installing fanspeedcontrol would conflict with builtin control.

Are there any config files for builtin fan speed control which can be edited?

The fan speed should automatically reduce gradually if the temps fall and remain below a threshold.

The Ultra 4 fan needs to run reasonably quick to keep the PSU cool.

Hello,

I am aware of that, and yet I would like to make them run slower, how can that be done?

heat will shorten hard drive life, also affect cpu, motherboard, memory and power supply longevity

suggest not even think about reducing fan speed

[mrQQ]

Well you are just stating the obvious.

System temperature is 30c, cpu is 41 and the fan is too loud.

There is absolutely no issue if it would run at 40c + 50c.

So again, is there a way to reduce fan speeds at idle?

Or, rather, just so that you understand better, how to set ramping up temperature higher. I have custom fan and it's runnin at 1800rpm even though sys temp is 30 degrees.

I want to lower that.
