I'm not sure if the board does have the connectors soldered to it. If not, you'd need something to read those sensors. Lian Li does make very simple ones, nicer ones come from Aqua Computer (aquaero 4.0) or mcubed (T-Balancer). Most watercooling stores should have sensors like these.

Btw., I did some Prime runs. The new bios seems to limit my overclock a little. Still testing, but I got errors much earlier than usual. Let's see if I can find some old benchmark values. Maybe they improved performance somewhere, tightened some timings, otherwise I coulnd't explain how this would have happened.
