SpeedFan older version
Some might say that new is better and that the force of habit is a symptom of laziness.
Unfortunately, after an useless upgrade of SpeedFan (an application that may watch your CPU temperature and adjust the speed of the fans accordingly), I remembered how the life before SpeedFan was. I live and sleep with the PC always on in the same room, and SpeedFan came to ease the noise. In addition, I have a buggy (Intel genuine) CPU fan and lowering the fan speed may actually reduce the CPU temperature. A registration process is required in order to get the settings for a specific motherboard and the settings may also be wrong, since they are uploaded by the users.
As an irony, at the first start of the newest version, the applications pops up something stupid about improved support for my motherboard, when in fact it does not adjust the speeds anymore.
I have found an older version of the software here. That’s an external link and it is subject to changes. But anyway, HTH.
