Flash Cerbios. This will allow you to set the fan speed in the ini file on the C drive. Cerbios already supports 128MB. Edit: Oh, that's right: You CAN'T use Cerbios because MakeMHZ didn't allow it. I'll defer to @KaosEngineer. He knows more about what evox has and doesn't have. Quote Link to comment Share on other sites More sharing options...

You can hard-wire 12v from the power supply and dial the speed you want in with a potentiometer, diode or voltage regulator. 1 Quote Link to comment Share on other sites More sharing options...

That's actually a good point. You could put the potentiometer in the back of the console. @Fullcrimson Quote Link to comment Share on other sites More sharing options...
