I've been having trouble enabling manual fan speed control on my Asus GTX570 card, so much trouble I decided to drop the recommended strategy for enabling manual fan control and do it my way which of course is always the best way (haha). I removed the card, opened the case, unplugged the fan from the header pins, figured out which pin is + and which is - and connected it to a wall wart type AC adaptor that is rated for 5 volts DC but gives an open circuit voltage of 8.5 volts. I cut a notch in the side of the case for the wires to hang out, put it back in the computer, booted and it works. I expected that the card would notice the fan is no longer connected to the card and refuse to work but it does. That's fortunate because it removes the need to rig a dummy fan just to keep the card happy and thinking it's in control. However it says some rather unpleasant things about thermal protection does it not?

Anyway, I am no longer interested in making Coolbits 4 work. I will hack the card and connect the fan to my own controller so that I will have manual control even without Coolbits 4.Done?

Ok, I got the proper torx bit, a T6, and dismantled the card (Asus GTX-570). There was dirt EVERYWHERE inside except in the heatsink fins in spite of the fact I've been blowing it out every few months. I'll be dismantling that card every few months now for a proper cleaning as I now see there are just too many nooks and crannies inside where the dirt can collect and not get pushed out by compressed air. There were probably 10 ICs that were completely buried in dirt and I bet they were overheating. I'm very glad I dismantled it.
