Coolers

Leadtek WinFast GTX 580

A familiar cooler with a vapor chamber. Fan speed changes smoothly based on temperature, so the overall cooling efficiency is higher and the fan is almost silent.

The cooler is identical to the previous.

Leadtek WinFast GTX 560 Ti GDDR5

This cooler has a primary heatsink and a fan in the middle surrounded by a large heatsink for memory chips. Both heatsinks are interconnected with heatpipes. The cooler is very efficient and silent. It takes hours of heavy loading to hear at least some noise.

This card doesn't get a hot, so its cooler is also simpler but still as silent. Memory chips are not cooled.
