Overclocking
Club3D GTX 560 CoolStream Edition runs at reference clocks.
Overclocking the GF114 should not be a problem, regardless of whether it’s reference or specially designed GTX 560 Ti or GTX 560.
CoolStream’s cooling provides a nice foundation for a healthy overclock and we got to following results. We managed to push the GPU from 810MHz to 1005MHz, after we upped the voltage to 1087mV.
Although we didn't manage to hit constantly stable 1GHz, the GTX 560 Ultra Charged allowed us to enjoy gaming at 990MHz for the GPU.
The fan was pretty loud after overclocking, but we're pleased with cooling results. 
When running at reference clocks, the Club3D GTX 560 CoolStream Edition's temperatures were in normal limits, as you can see from the pictures below.
