Thought my Jetway Ha08 Combo motherboard had PWM on the 4 pin CPU header but it looks like it's just voltage regulated after all. As a result, buying a molex powered Akasa PWM fan spitter cable (with molex for power) just resulted in all the connected fans spinning at full speed.
I'd still like to control all the fans with the motherboard BIOS (don't want controls on the PC exterior for baby boys to play with) So - back to the drawing board. The manual says the headers are rated for no more than 350mA. I reckon that's one - maybe 2 - fans maximum. Case fan headers aren't controllable, hence needing to use the CPU fan header.
So - to allow the CPU fan header / BIOS to control all case fans etc, I've ordered an mCubed Fanamp (rated for up to 25 watts analogue). Planning on connecting up the fans in parallel using splitter cables, with only the CPU fan providing RPM info to the motherboard. As well as allowing the motherboard control there's also a remote temperature sensor that you can select an override temperature for. This sets all fans to 100%, if it goes over a selectable over-ride temperature. I'm thinking of either putting this high in the case (set to high 30s) with or on the GPU cooler card (set to whatever my graphics card gets to under load with case fans on low)
Has anyone used a Fanamp? Anyone got any comments on the proposed setup?
