How to cool an NVIDIA Tesla P4

I’d tend to agree, unless someone needs the CUDA or passthrough-gaming functionality.

I assume it’s actually a 4-pin PWM fan and it isn’t just masquerading as one?

I do have a couple of P4s but right now their blowers are just set to a static speed as @TheColin21 where they can’t really be heard over the other fans. They don’t do much of sustained workload so this is fine for them.

A community user has written a Docker container they nicknamed “truefan” that seems to work - however it does require running a privileged container and giving it access to the /sys and /dev directories so that bears a certain level of risk.
