Idle Delta - Temperature between Idle GPU and the ambient

Load Delta - Temperature between loaded GPU and the ambient

Temp Rise - Temperature between Idle and Loaded GPU

As you can clearly see the BlastFlow Siberian modular waterblock's powerful cooling potential, reducing the temperature of the loaded GTX280 by as much as 39 degree compared to stock heat sink and fan, and 20 degree when the GPU is Idle. Even when under load the Siberian was able to keep the GTX280 12 degree cooler then stock GTX280 when idle!

With the BlastFlow Siberian installed and a quick overclock of 725Mhz core compared to 602Mhz stock, here is a glimps at its potential.

A raise of almost 1000 3DMark06 score was easily obtained with the overclock, and the rise in temperature from increased core frequency was negligible.

Well there you have it. It is very obvious that there is much more room in the GTX280 GPU to manoeuvre then nVidia would like you to believe, and with more time to tweak, or even a volt mod or two, I’m certain BlastFlow water-cooled GTX280 GPU will run ever faster and the Siberian GPU water-block will handle it without a sweat.
