For video cards, the Asus DirectCu video cards have good coolers that are very quiet. Other cards by Gigabyte and MSI sometimes have good coolers, and sometimes have coolers that LOOK good but are noisy.
Arctic Cooling's range for video cards are quite good for being quiet if it's an aftermarket heatsink that you need.

Though I haven't used them for a few generations, sticking with the Asus products recently.
