I have a somewhat amusing question. It's an unusually cold day today and I want to know if it is possible to stress my iMac enough to heat my bedroom. It's a small room, and I already run BOINC 24/7, but its just not enough. Is there any way to stress the GPU out when at idle? It's an iMac 7,1, so it doesn't support CUDA, not that that matters since my mini does support CUDA and I've never been able to get it running properly on BOINC.
