H80i v2 not detected by Corsair LINK also 38-44 degrees idle

SirSavageIII · Jul 21, 2017

Im not sure how big of a problem this is but my new i7 6700k is idle around 40 degrees and in my bios under the water pump option it says N/A and it is not detected in corsair link. I have the radiator front mounted (only place it will go). I ordered two more case fans and going to put one on top as outtake and I dont know about the other one

I suspect you did not connect the H80i unit to your mobo according to instructions. There are four things to be done.

1. The pump unit has a cable ending in a female 3-pin fan connector. This MUST plug into the mobo CPU_FAN header, not any other.
2. The pump unit has a cable ending in a SATA connector that must plug into a SATA power output from the PSU.
3. The two fans MUST plug into a socket on the side of the pump unit, using the Splitter included. Do not plug them into a mobo fan header. THIS connection is how the system can execute the instructions from Corsair Link to control its fans.
4. There also is a cable that plugs into the pump unit and then into a mobo USB2 header. This is how the Corsair Link software can communicate with the system.

The Corsair Link software takes over all control of the H80i system, and does not leave anything to the mobo - that's why it needs the USB connection. By default, if it is connected wrong the h80i system will set its pump and radiator fan to a relatively high (but not full speed) setting to ensure that your CPU gets adequate cooling, although not full and not properly controlled. That is why your system is working, but need improvement.

I did not see any any cable with a SATA connector on it

I'm sorry, you are right. The 3-pin connector from the pump to the mobo CPU_FAN header is how it gets its power. And the two fans do not have sockets on the pump to plug into. Instead they plug into two sockets on the end of a splitter cable from the pump.
