ASIC miner psu operating temp

Can a Ck5 or an LT5 pro be placed in a cooler and have the fans exhausted with the psu being enclosed? Unsure if the psu would overheat inside the cooler.

It all depends on air flow. As long as you have air in and air out you should be fine. I think you need to add some ducts for efficient flow and to maximize the noise cancellation.
