programs using the wrong GPU

[supremedutchgamer]

so i have a dual GPU setup using a GTX 580 and a quadro 4000. the quadro is kinda suffocating in my system as its tiny fan gets blocked by the massive tripple slot 580 but thats not an issue as its only usecase is to provide extra video outputs.at least, thats what its supposed to do. but it keeps getting assigned as the main GPU for some applications, which rapidly brings the card to 100degrees C. ive checked all of my 3D settings in the nvidia control panel. and i think ive found the issue, while the base profile has CUDA set to the 580, it has openGL set to auto select, and in the drop down menu it just doesnt give any other option than the quadro. how am i supposed to change this? ive also noticed that i cant select the quadro for physx. if it keeps giving issues i can replace it with a K2000 which would be fine but id rather not.
