Awesome video! I don't actually use FreeBSD and had stumbled upon this by pure chance. Still very informative and helpful, I imagine. I actually have a T440p too with the exact same CPU in it and lord does it get hot (& loud).
Heh, yeah, I actually had to put in a lot of effort to get that chip cool enough. I do a LOT of stuff that pounds a machine at 100% cpu for days to weeks at a time and so I had to undervolt the chip and mod the cooling system. I added an extra copper heat bridge between the heat spreader and far end of the heat pipe made out of 2mm copper which also added a pile of surface area. Then, I went through and opened up the air passages on the intake side as well. It still gets hot to be sure, but at least it's not flipping out and the firmware isn't shutting it down anymore! :P Does yours ever shut down on you?
@@GamingHelp Mine doesn't shut down on me but the firmware kicks in some sort of power-limiting and locks the clock speed to 800 MHz until I reboot the machine. I think this is an issue with my charger, though. Supposedly this can happen if the embedded controller thinks the AC power adapter can't sustain enough current. The hottest I ever got the machine was building the Linux kernel. It's okay most of the time but the cooler is very weak.
