I have installed Genymotion for emulation and whenever i run a genymotion virtual device, the CPU fan starts running on high speed. I have :

Ubuntu 14.04 64-bit
Bumblebee installed

How can i avoid high CPU fan speed i.e. avoid heat up due to the genymotion virtual device?

  • How Fabby's answer worked for you? I've the same problem with Yosemite 10.10.4 in a MacBook Pro. Thanks. – GuilhE Aug 9 '15 at 23:29
  • @GuilhE did not try it but i noticed that it overheats only when the emulator runs some heavy graphics game or something. – Sunil Kumar Aug 27 '15 at 10:56

Easy: just slow down the emulator.... Open a terminal by pressing Ctrl+Alt+T and type:

apt-get install cpulimit

then, limit the amount of CPU cycles of genymotion. Again in (the same) terminal type:

cpulimit --exe=genymotion --limit=xx

where xx is the % of CPU you're willing to give it. (I would start with 50)

Now start genymotion normally, while keeping the terminal open.

If the fan is still too loud, click on the terminal, press Ctrl+C and then type the cpulimit command above again lowering xx until you have a comfortable fan speed
