with CUDA (or any of the puddinpop miners), is there an argument/parameter to force the GPU/CPU to sleep between cycles?  my GPU on my laptop (Nvidia geforce gt 525m) gets fairly hot when I attempt to run guiminer.  I think the first time I ran it (with the default guiminer miner), laptop shut down after 20 minutes of so (overheat protection I think).

Did a lot of googling, but no luck.
