I have a blackbook that makes the mooing fan sound with the fans going on and off at a certain temp usualy around 67C. Well today just playing around with the power saving options on my notebook i seem to have stumpled apon a way to lower the likelyhood of mooing and reduce the cpu temps at the same time. Basicly what i did was set the power saving options to beter energy savings and then afterwords my idle temps droped. Before I was runing around 65-68C right in that point were the thing starts mooing. Now my temps are in the uper 50s. I have to be pushing the system in order to get it too moo now it seems. Anyways for those that havent allready thought to try that to reduce your mooing its worth a go
