Enermax PS owners, got a question about thermally controlled 2nd fan

Does anyone know the temperatures that the 2nd fan in the Enermax PS increases and decreases its speed, and what the speeds are? I just got mine today and it is running at ~2550RPM.

It IS noticeably quieter than my two year old Powerman 235W PS. I also like that it makes my processor run cooler because it has two fans, one directly above the processor. I was disappointed, though, that even though it is supposed to be a 2.03 ATX PS it doesn't come with that extra 12v connector future things may need.

I have the 351 FC.
 
Im not sure of the speeds, mine ran at about 1800 RPM till I modded it and all the fans run full speed now.
 
I stopped using that feature and unplugged that monitoring attachment. I had a warning where the system was running hot and the fan controlled by that sensor was still running very slow. It rebooted unexpectedly at at random but all symtoms went away after I unplugged the damn thing. Maybe the connection on my P3V4X is going bad but not 100% sure though.
 
I just bought that thermally controlled fan and is planning to install it in my PSU. My question is: Where should I attach the thermal detector?
 
I found that the thermostatically controlled fan was a useless feature. All it knows is how the power supply is doing. Your CPU chip could be on fire and it would still churn along at what ever speed made the PS cool. I have discarded the speed control device on every computer I have that is so equipped in the interest of better cooling for everything else. All that I have encountered are mounted on a heatsink inside the power supply and connected in series with the fan. In fact I am looking at one on my desk that I just removed the other day.

It's true that thermally controlled fan doesn't allow maximum cooling performance. However, it's the best solution for me since I need a silent fan. This low RPM Enermax fan is really quiet.
