Tool to Control Fan - fanctl

[tuxd3v]

Ok the Test started the fan.... can i change it that it does not start at 40 but at like 30 oder something? i want to cool the HDD´s...  or is there any other way? can i somehow change it, that the fan starts when the HDD´s get like 40c?

Hello stFfn,

You can change it, but you would not be able to get CPU lower than lets say 37C..
The block driver, I think it doesn't provide sysfs SMART, capabilities..

You need to me querying them constantly, and for that a lot of changes need to be done.
I don't know if exists, any god way for that..

You can change what you want, because the code is opensource   
One simple way would be to adjust the timers, for the triggers, so that the fan would be more time running..
but, for that you need to go into the code and adapt it..

Or follow romtorwator, advice.

the HDD´s getting to 60°C

For a fan on the chassis, install a thermostat eg KSD9700-60-NO, in the fan circuit, when the fan is powered by +12V,
on datasheet KSD9700-60-NO, he close the contact at +60°С, will open at a temperature of +35°С, or KSD9700-55-NO - close +55°С, open +30°С
in reality (burst tolerance), these thermostats is better to choose, KSD9700-40-NO in reality it close 41.8°С, open 36.1°С
they have a hysteresis of about 5 degrees
I personally used a programmable thermostat based on DS1821

also you could change the profile, be default it his on profile 1, which is for smaller fans,
you could change for profile2, or profile3,
But first it would be nice to have the output of that command.

Hello Girbur,
Like I said, its in line 68:

Code:

68         FANSPEC                         = "profile1",

profile 1, for 10mm fan
profile2, for 20 mm fan
profile3, for Bigger Fan
Only the pwm is adjusted, here the triggers, remain the same..
Ofcourse you can also adapt the triggers, starts in line 91:

Code:

97         setTriggers     = function( self, x )

You can adapt those timers,
For example to run for longer time, or to stop for longer periods of time..
