You could add a third fan as I did in my VGX redux project. You would likely have to use a y cable and run 2 fans off of a single header, but it is possible.

Hi Oliver,
Sorry this machine is really part of the familey and i cant risk it... i know that a slower or faster fan will need programming in to the bios and I'm not confident enough to do that myself.
The power consumption and flow velocity are probably different and i have no idea where to tune the motherboard outputs..
If anyone else wants to try theyre welcome...
cheers

I thought you could just plug in faster or slower fans without doing anything in the motherboard, just a straight swap. The power and airflow is different on all fans. As long as the airflow is the same or greater I don't see any issues. The tiny bit of extra power it might use is not likely to make any difference. Infact, if you use a graphic card with a fan you'll already have more fans than the machine originally shipped with. You could likely get away with using fans with slightly less airflow without any issue. Just don't use the ultra quiet fans with much lower airflow. If your worried about airflow the everflow fans in the OP's comparison table seen to give slightly more airflow whilst simultaneously being slightly quieter.

Yeah, theres a post moduel in the bios which acounts for heat capacitance variable to load on the cpu. I.E if you load the cpu continuousely or uncontinuously.. makes a difference... the fan can be PWM to acount for this.. but the exact correction needs to be learn by the motherboard. Encouraging the Motherboard to post predict on the fan controler needs to be induced.. this can be done by changing the resistance of the fan... so by replacing the fan... But I would like a hard and fast note of the fans capacity relayed to the mother board or it will just super accelerate the fan every time it boots... there are tuning calibrators in some overlcocking or boost enabled motherboards.. but this is not one of them.

Thanks for the I information, fortunately I never needed to replace my fans before I replace my HTPC. As the vgxxl range continues to age, and original fans behind harder to find, the fan issue could become a real problem I guess? I did nothing to the BIOS in my custom HTPC when installing fans, but I guess the modern motherboards have some kind of intelligent fan program built in, I'm sure I read that somewhere.
