After all the feedback i got from this post – [https://www.reddit.com/r/gpumining/comments/nj5jvh/ssd_riser_i_made_to_install_more_cards/](https://www.reddit.com/r/gpumining/comments/nj5jvh/ssd_riser_i_made_to_install_more_cards/) (wish i could correct the title, to include “mount”).
I decided to get a little scientific and do some testing of my own to see what effects the different ways of running my setup has on temperature. Starting with worst case scenario of completely closed case, then removing the front, then removing the sides, and finally moving the cards outside the case. Here are the results:
As you can see from the above, the GPU in the stock PCIE 16x slot did indeed go down in temperature when the two other cards are moved outside. However the two cards that are now on my desk both had their temps increased. If i were to explain why that is, i would have to say it’s due to them being outside the airflow of the case fans.
I have no doubt that the best solution for cooling is to run an open frame with high cfm fans mounted to the front.
