Today I turned an old PC into some kind of a "server", which means that I want to leave it running 24/7. I don't need any display as I will use the machine via ssh so when everything was set up I removed my monitor. After a hour I checked my graphic card's cooling system and it was still hot.
My graphic card is GeForce 8600 (with DVI connector), OS is Debian Linux.
Does GPU render anything when there is no monitor plugged in?
What is the best solution in this situation (standalone server) if GPU is active and I don't want it to waste power?
