I have a Dell Optiplex 3020 ( i3 processor) Desktop computer of the mini tower type. I have recently installed a PNY 2GB graphic card model GT 730 with a heat sink and no fan. I don't use the system for gaming. I just need better graphics for watch photos, videos or movies. I would like to know if I permanently keep my computer in sleep mode (for ready availability when I need to use it) will it heat up overall system because of the presence of the 2GB graphic card.
