Currently I have a MSI R4850 2D512SP OC which has the same small-4-pin fan cable as this one
black/yellow/blue/blue

and since the fan isn't controllable, so I'm looking for a converter with small-4-pin-female to 3-pin-male
similar to this

but I need a 3-pin-male instead of 4-pin-male, I need to plug it on my MB's 3-pin-chassis
so I can control the fan speed by using Asus's software.


either a converter or a fan controller would works perfectly for me
I've look eBay and it's selling only 3pins converter/controller.


Thank you in advance.

yeah, well, sorry to disapoint you, but, no 3 pin fan can be controlled by software. only by direct voltage modulation. thats what the first 2 pins are for. the 3rd is for showing the RPM that the fan is spinning. 4 pin fans can be controlled through software if the motherboard has a 4pin connector and the software to support it.

Thank you.

Actually, it does works even with 3-pin, but only at fixed fan speed.
I got a friend tested it on Asus P5Q Pro.
I'm not sure if it will works on me as well, but worth a try at least, the 100% fan speed is just way too noisy...
