Nothing special here. Don't laugh. But I need to share my joy.
For some reasons the last time I tried undervolting my laptop's CPU, it didn't work. I must have done something wrong (didn't have any guide). I'm really glad I tried again.
I tried to "undervolt" my laptop's CPU 2 days ago and... Success ! My CPU "idle" (well, semi-idle...) temp went from 60-65C to 40-45C. A whopping 20C. It's super stable (tested it with Orthos, prime95 and just did a lot video rendering) and I don't feel like I'm slowly cooking my hands anymore...
Not only that, but I also gained some extra "battery life" and a barely audible fan.
