BES is GPL free software that controls per-process CPU usage: an “active” software CPU cooler. It throttles CPU-hungry application(s) when asked. BES works on Win7/Win10/etc. (if necessary, run it in the XP compatible mode—probably not necessary), but perhaps run it with the admin privileges (right click > "Run as Administrator"). It is a small tool that throttles the CPU usage of the process you “target”: for instance, you can limit the CPU usage of a process which would use CPU 100%, down to 50% (or any percentage you’d like). With this, you can use other programs comfortably while doing something CPU-intensive in the background. By limiting the CPU load, you can also cool down your CPU immediately when it happens to get too hot. It’s an “active” software CPU cooler. Conventional soft-coolers save CPU energy by making CPU sleep when it is idle. They passively wait until CPU gets idle. BES is more aggressive: it cools CPU by making the “heating” process slow down, i.e. periodically forcing CPU to be idle for a short time. Furthermore, BES can hide a window you don’t want to be seen for some reason, without killing the process, and restore the hidden windows again anytime you like. To Gamers: Adjust the Sleep/Awake Cycle in [Control] so that the video won’t get jumpy/choppy. You can also control the parameters via command line.
