Corsair HX750 - no fan control
Hi all, I just pulled this PSU out of storage and was happy that it still works within expected parameters, but also disappointed to find the fan is stuck on at full speed. From what little I've been able to find on the web, this model's controller makes decisions based on load as well as temperature. As the system I'm using it with doesn't even have an OS installed it seems unlikely that load is the problem, and since the unit isn't even in a case yet I'm guessing there's an issue with the temperature sensing.
I'm going take some measurements via IR thermometer and then try powering a live system with it. Assuming those tests don't reveal any surprises, can anyone suggest how I'd go about troubleshooting this so I can repair it?
BTW this is the original CWT-built model with the all-blue decals, whereas I believe later revisions were a bit different.
