this is exactly why i posted this. I learned some new tool :)

o so a real server chassis provides that airflow but because of the lack of flow in towers/desktops they get overheated i get it, good to know

p40 I’d be glad to run a benchmark on, just tell me how.

yeah i think that’s kind of the issue today there isn’t really a benchmark for that kind of stuff. from what i understand the p40 is perfectly capable of running some larger models because of the 24gb. what i don’t understand is you are talking fan and fan coupling what do you mean with that is that required i have a supermicro sc747 see link for example would that require more airflow trough the gpus to cool?

just wondering but isnt a airco kinda overkill would a fan to the outside not be enough? I mean yea if you have 20c (68f) air vs 30c (86f) the 20c air is going to cool better but if that means 800w of power consumption to cool a 400w server that means a big powerbill here in the eu.

so looking at your “server” it seems like a workstation i have no experience with k80’s but from what i know all server gpu’s are designed passive to be cooled by some loud fingerremover5000’s so i think if you would upgrade the fans it should be fine since its only 300w. if cooling really is a problem than maybe some shrouds might help it but i don’t think a single k80 is difficult to cool since in the data center they probably ran 4-6 in one 4u chassis
