These parts of gpu were not factory cooled, is it suggested to do so, if using a universal water block cooler. Looks like a section of vrm 2 on back of card, bottom lower looks like vrm 1 with bios chip. Then the top right is Mofset. These on most gpu's are cooled normally aren't they. Would it help Overclocking if they were cooled, or is just moving air sufficient. Its hard to believe there on the card for looks, expensive machining for non-functional components.
