cpu workload isn't broke, works fine. Think you are having a different issue pino. Mine is normally near zero until I do something.
As to the fan's not running correctly when you have fangui trying to control them. There is a simple fix.
I've noticed with mine, with I have running in Temp Control mode, that sometimes it runs just as expected, and others when it's time to kick the fans on high, it fights the bios. The only common issue I've suspected so far is the temp of the cpu when the computer boots up.
So the simple fix. I turn off the temp control, and just work for a while, or maybe start a 3d app. starting any 3d app seems to bump the temps 10F almost instantly. What I've found is this. I have the fans kick in high at 116F then go back to low at 102F. If fangui and the system are fighting for control, stop fangui from controlling, and let the temp get to at least 120-124F. Then, when I re-check the Temp control box, the fans immediately kick in high and run normal the rest of the time the system is up. The next time I start up, fangui usually runs fine.
Just let the temp get about 8-10 higher than you want the fans to kick on high and it seems to stop fighting the system. And then you can keep the system even cooler by having the fans kick onto high often.
