Underclock cpu to achieve low temps

I have a laptop that gets up to about 51c and id like to underclock ... and lower the temps.

Just out of curiosity, why do you think 51°C is too high? My i7 laptop typically runs at about 50°C...



...and peaks at 85°C when working hard, but that's well under its Tj.Max of 100°C so I'm not concerned.

I have an sff pc that tops out at 80 f and my laptop runs about 120 f at an idle

I use ThrottleStop to undervolt my CPU which is good for dropping temperatures without reducing performance. It will work on any PC (I run it on a MacBook with no BIOS options at all) but your CPU must be supported (Intel Core 2 or Core i)

Because it is a user program not BIOS change you need to schedule it to run at startup. I use NSSM to run it as a service like this.

Power Options wouldn't really do good even if you put it at 5% minimum processor state because the OP wants to have low temps while on considerably heavy load not just idle load.

If my laptop got up to 120 due to a heavy load but at an idle is kinda crazy.
