open air internal exhaust cooled styled uh G1 gaming 980 from Gigabyte to control the temperatures in the rest of the case we used a 240 mm aiio cooler to pull the heat away from the CPU and what is a pretty common use case uh these days and we used a control graphics card to interfere with the airflow of the two other test cards I use a Titan X as our control card as it isn't too long and it isn't

next to our test card is a whopping 114 MHz which would actually be quite a noticeable difference in terms of performance but that's not where the story ends as the difference between the control card being right below the test card and the control card being as far away as possible is still 88 MHz which is still a very noticeable performance Improvement just for optimizing your expansion card layout but what about the internal exhaust card well the G1 gaming 980 actually did manage to get away from the good old classic NVIDIA standard of 83° while by itself in the case meaning that when we added the control card in the furthest away position the clock speed didn't go down like it did with the blower card but the temperature did go up slightly but it still did go up that being said when
