The version that all the press reviewed last week was 70.00.10.00.01 and the latest build with some minor tweaks and bug fixes is version 70.00.18.00.01. Since Legit Reviews was the first site to point out the high temperature issue when using two monitors, the engineers at NVIDIA were kind enough to let us try the latest vBIOS build to see if it fixed our heat issues as the new vBIOS includes some new fan profiles.

We gave the build the good old college try, but we were still sitting around 86C in GPU-Z when we tried it out today. We gave our feedback to NVIDIA and several hours later they got back to us with this:

"Upon low-level examination of the GPU-Z application, we have determined that it is not using our NVAPI for all temperature/fan control calls, but is instead banging registers directly. This is interfering with our fan control and causing boards to crash when GPU-Z is run in the background. We need GPU-Z to use NVAPI to avoid these conflicts..."- NVIDIA
We have had random crashes with the GeForce GTX 480 graphics card while running GPU-Z in the background, so it's great that the issue has been identified and solved. We expect a new version of GPU-Z to be available soon that should address all issues. NVIDIA also thought that GPU-Z might be the root cause of the fan anomalies, but when we fired up the system from a cold boot and opened just MSI AfterBurner, we found the GPU to be idling at around 84C, which is again a tad too hot for our tastes.
