* I'm sorry I'm bad at English... I'm using ASRock Z68 Pro3. this has 6 fan connectors and 2 of those are CPU's. problem 1. basically, AIDA64 can't sense a fan. AIDA can sense that when AXTU (ASRock's monitoring tool) is running. and if AXTU would be closed, AIDA can't sense again. problem 2. two values of CPU fans are sensed by turns. if only fan has connected, value is flickering. (no problem on AXTU.) * I guess that Z68 Extreme4 has same trouble. that has same fan-system.
