Added a balls cooler to my G920
(lemmy.nz)
The picture shows 2x 80mm fans, mounted under a Logi G920 with a custom wheel.
I will probably implement a PWM circuit to control them.
No, there is space between the fans and the desk. They are actually in an angle, so that they ~~blow~~ push air a bit out of the desk, instead of straight down.
