Take note that the test setup is a run in a highly ventilated chassis. Temperatures could differ from enclosure to enclosure. Secondly for the temperature results of the EK Full Cover block, consider that the Intel i7-3960X is running at 4500MHz at 1.35Vcore . Thus also contributing that a little extra heat in the loop.
First up the Stock Temperature results of the boxed cooler versus the Full Cover EK waterblock.
The maximum temperature our stock cooler equipped TITAN graphics card reached was 79°C. At IDLE the card was hovering around 35-36°C. Not bad for such a powerhouse, but things can only get better when you equip such a powerful card with a waterblock. IDLE temps drop 4°C after installing the EK Full Cover TITAN waterblock. Already impressive, but the best is yet to come. The load difference between the air and watercooled setup is a whopping 43°C. The ambient room temperature was 20°C during the conduct of the tests.
Time to play some more and install the ASUS GPU Tweak tool. After increasing the Power limit to 106% and dragging the VGPU slider to 1212mV ( stock is 1175mV ) we tried to find the most stable clocks for our TITAN card. Seemed it was far from an impressive clocker, compared to some review samples, easily surpassing the 1000MHz barrier. We hit a brick wall at just 979MHz Boost speed. However the final score for the Vantage run was lower then the previous test at 10MHz lower. Rerun at 969 and 979MHz, jielded similar results, with a better outcome for the lower clocks. The TITAN card was throttling. Since this was a borrowed card from the TONES shop, no firmware update was done to disable this throttling feature. Hence the overclocked temperature results were done at 969MHz boost speed, set via ASUS GPU Tweak.
Slightly higher idle temperatures for the reference cooler design, yet the maximum temperature logged was again at 79°C. The EK FC TITAN block keeps the card again well cooled, albeing it with a small overclock. The block allowing far more temperature headroom then expected, the limiting factors for a high overclock will be the quality of the GPU and the reference nVIDIA VRM design.
We continued our OCing quest on the EK FC block and quickly hit another brick wall at just 1010MHz boost speed. 1020MHz via GPU tweak would occasionally crash during the Vantage runs, so far from stable.
