I just bought a "new" homelab server and am considering adding in some used/refurbished NVIDIA Tesla K80s. They have 24 GB of VRAM and tons of compute power for very cheap if you get them used.

The issue is that these cards run super hot and require extra cooling set ups. I was able to find this fan adapter kit on eBay. But I still worry that if I pop one or two of these bad boys in my server that the fan won't be enough to overcome the raw heat put off by the K80.

Have any of you run this kind of card in a home lab setting? What kind of temps do you get when running models? Would a fan like this actually be enough to cool the thing? I appreciate any insight you guys might have!
