I'm trying to learn how to use Speedfan.
I have used UGuru to change fan speeds but UGuru does not seem to change the CPU fan speed anymore. I keep trying to lower the speed as the core temps are about 39C as reported by Core Temp Program (CPUZ utility); & I'd prefer less fan noise.
Biggest Zalman fan installed & running at 2700 rpm (max.). I lowered the voltage to even 40% high setting & no effect; remains at max. speed.
Secondly, should I only use one of these Programs: Speedfan or UGuru to change fan speeds. With Speedfan I note I can change UGuru fans speeds within Speedfan, thus do I then stop using UGuru?
Do these utilities conflict with the other?
Seems like they might if settings were different, one program to the other.
I'd just like to learn more about this topic; sure I can just live with a fully revved-up CPU fan,
but I keep wonder why I can't lower the speed, as these Programs are suppose to just do that.
