Nvidia Quadro 4000 Mac I Noticed

Just after I installed my new Nvidia Quadro 4000 for Mac I noticed that the fans are running at a much higher speed, everything else is working fine though, has anybody else noticed something like this.

Ive installed the Quadro 4000 on the PCI Slots 1 and 2 (both x16), just to try different locations but its always the same issue.

I dont think the issue is temperature related, sometimes for no reason with the Mac Pro idle the computer fans will start ramping up speed up to very high RPMs, and sometimes with load on the computer the fans will run at very low RPMs, so I do not see a correlation between temperature and fan speed.

If I run Cinebench and execute an OpenGL test the Fans RPM will go down to the normal values and will stay there, this is really weird, it seems like the card needs to be activated or engaged by some OpenGL application and the fans (Expansion Slot and Power Supply) will return to their normal values.

Ive been monitoring temperatures with iStat Menus, monstly CPU temperature and always in normal ranges, around 38C to 40C.

The Quadro is a power hungry card to obviously it will trigger the SMU to increase fan speed in response.

Nvidia Quadro 4000 Mac Pro Increasing

Im guessing its just the mac pro increasing airflow to prevent overheating.

I had hoped to record the occasional vocal in the same room but that wont be happening now.

Has anyone found the fan speed to be unnecessarily high or is this just the price for using a powerful non-native card with NVIDIA drivers.

I recently installed a Quadro P4000 in my 2012 Mac Pro and have the same situation where the fan noise is significantly higher.
