Tbs5927 fan control

Tbs5927 fan control

Postby Ericed1965 » Mon Jul 31, 2017 2:49 pm

I received my tbs5927 and installed driver on ubuntu 17, it is working fine.
However, the fan is blowing fast and noisy, is there a way to diminish that noise?
I saw in the windows section a recommendation to disconnect the fan, i find it a bit weird as i read at many places that the tbs5925 was a bit hot. So i would rather go for diminushing the speed (by 2?). For this effect, what resistor shall i insert in the power supply line of the fan?
Thanks.

Hi Ericed1965

You can have a try add one resistor to the power supply line of the fan ,what resistor you can try with a smaller first if you still
think it is fast you can add more bigger then find the right one you want to use ;)

Thanks

Kind Regards

Thanks for your reply. Do you by any chance could find out the resistance of the fan? It would help me to find out what resistance to add.
I suspect it is a 12v fan, but how many amps? (I can see the tacho is not connected, which is normal).
I am thinking to place a small potentiometer like that I would be able to adjust the speed better, however to get the right portentiometer I need some more information about the fan spec. Can you ask your engineers the fan spec please?
Thanks for your answer.

Bourns 3006P-1-201LF does the job, silence is back, with a gentle air flow in the box.
