BEFORE YOU INSTALL YOUR Corsair H80 UNIT
1) Ensure that the fans are properly connected to the radiator unit (one should blow into the case through the H80 radiator) the sticker on the reverse of the fan will be hidden, the second should be attached with the sticker visible from the inside of your PC Case, this means air is blowing through:
>>OUTSIDE CASE>>CASE WALL>>FIRST FAN (Sticker side attached to radiator)>>RADIATOR>>SECOND FAN (NONE Sticker side attached to radiator)>>INSIDE CASE>>>
2) Plug BOTH fans attached to the radiator to the pump unit that is attached to your processor chip, there are two plugs for this next to each other...do not confuse with the CORSAIR LINK plug
3) Plug the small power cable from the pump unit (the bit with the profile button on) into the CPU Fan header on the motherboard, don't worry if it is 3 pin and you have 4, use the grove on the connector to guide you as to which 3 pins you should use...you should use
4) Plug the MOLEX (the bigger connector) into your power supply (not into a fan controller)
5) Boot and check both fans work and air is drawn into the case and the Corsair logo lights up on the pump...all good?
6) Go to your BIOS and disable any profiles you have on the CPU fan, whilst I'm not sure what this will do, it seems likely that the BIOS trying to adjust power to a pump is probably not a good idea...if Corsair can clarify that would be great
