TemperaturesStill in the same casing, we took a temperature reading of the GPU using internal sensors:
The GF116 is well cooled with similar temperatures to those of a GeForce GTX 460.
Here’s what the infrared thermography image shows:

Asus GTX 550 Ti DirectCU TOP in load
At idle, you can see a hot point where the controller is on the power stage, while in load the whole of the power stage gets hotter. It’s not problematic though a little dedicated radiator would probably have brought these temperatures down.
