I'm going to install this to my 4870 as soon as I receive my cpu cooler this week and will use the TX-2 bundled with the cpu cooler instead of the white paste from the akasa. That's gotta be better I imagine? There's a 3 pin motherboard plug with the akasa and a 4 pin molex adaptor. Should I use the molex to power supply to power the akasa fan, or should I plug it into the only remaining motherboard header I have which is the pwr fan header?
