Power supply fan in the 1000HX

[mrarkus]

On my quest to upgrade and modernize my HX, I want to replace the PS fan with something quieter. Does anyone know what should the minimum CFM be? If I put a Noiseblocker fan with a 14CFM, would that be enough? Any other recommendations for a quiet fan?

The real problem is the size of the fans, so unless they have a new fan blade design that cancels out the noise similar to what apple did on the MacBook Pro, you're going to be hard pressed to find something quiet with enough airflow. PCs went to 120mm fans over 80mm fans to keep flow up and reduce noise.

There might be a fan that will work, but first you should find out what fan you already have. The Tech Ref doesn't have a parts list and there were more than one power supply used. Then find something similar in CFM with a lower DB noise that still fits in the space allocated to the fan.
