Any way to slow down Handbrake?

The question sounds stupid but...

I like to let Handbrake take care of some batch-converting overnight while I'm sleeping. However, it's better to lower the CPU usage so that my MacBook Air fan wouldn't be running at 5000+ rpm while I'm sleeping besides it.

Is there any way to allocate or throttle CPU usage? Is it possible for Handbrake to convert in a slower and less CPU-intensive rate?

Thanks a lot. :D

Would it be too difficult to run the task in another room?
I know... I'm just too lazy to move my whole set-up (MBA+power brick+external HDD).

And I do wish to know if there's any way to process something slower if I got the time. (computer staying on overnight anyway)

Well, I have not done any research but I would not be surprised if you could change Handbrake's priority (nice) or even force a transcoding frame rate limit. Survey says you will do it via the command line or passing some parameters in.

If you really decide you need to do something like this, see here:

There's a link to a program called cputhrottle that should do what you want. It can set a maximum CPU share to a PID (as opposed, I think, to using nice, which will downgrade the app's priority, but will not stop it from using CPU time if no one else wants it).
Thanks, I will look into that.

You guys are quick! thanks for the inputs and keep them coming!
