Maybe.
There are 2 control methods, one is no signal on Blue = full speed which in my book is the safest, the other is no signal = lowest speed. Looking up the fan specs should say which they are.

I've never played with the fans so just cut the blue on one fan and see what it does, you can always splice the wire back together if it slows down. Beyond that setting min fan speed to 100% - should - force them to always run full speed.

Thanks - unfortunately, the specs for these fans are nowhere to be found... So I guess it's testing time.

I've read posts about manually setting the fan speed to 100% but it seems complicated with a lot of uncertainties so I'd rather go the hardware route.

How about the voltage in? Is my assumption correct that since the fans are controlled with PWM, the input voltage should be constant (always the full 12V)?
