Separate time specified between running CPU and GPU applications

[Ageless]

As posted on the BOINC Dev forums:

Just bought a new PC (Q6600, 9800GTX+). 
I usually let BOINC run all the time, but with CUDA Apps and the noisy fan
of the 9800GTX+ Graphics Card the PC becomes very loud. The CPU Fan is really quiet,
it is just the GPU Fan. If i turn of BOINC, the GPU Temp drops and the GPU Fan 
falls silent.

So I wonder, if it is possible to run CUDA apps only after a specified time 
(away time), while the CPU Apps stay active all the time?

I forward it to here as a request for enhancement.
