Enermax PSU design issue?

[DivideBYZero]

I have a 350w Enermax, and it has the 80mm fan at the back and a 92mm fan underneath, but it also has a grill that faces into the case, opposite the 80mm intake.

I have found that hot air exits here, as it is pushed through by the 92mm fan. I know the 80mm is supposed to exhaust this dependant on temps, but it does not seem to speed up enough.

I put a cover over the grill and the 80mm fan sped up, indicating that the temp sensor was not picking up the actual temp of the PSU properly. I have now put in a blow hole at the top, just after the grill to expel air from the hot spot, but this is just fighting this hot air.

Anyone else had issues with these PSU's and hot air?

How hot is the air? If its supposed to change with temps, its probably going to stay quiet and still blow enough air to keep it from frying. My Antec True 380W doesn't spin very fast and the air coming out is pretty hot but its still fine and hasn't had a problem yet.

Isn't the temp sensor that little cable thingy that comes out of the PSU? It's kinda like a flat, rounder thing... I am so bad at describing things...

Is your PS the EG365p-ve? Thats the one i have and its exactly like how u described it. I never feel any hot air exiting that outer grill. Im guessing that 80mm isn't spining as fast as it should.

The last time i checked the inside of the PS, I couldn't find a temp probe. Im thinking its attached to one of the heatsinks..

Yeah I think so (at work, can't dig out manual). It's the one that automatically adjusts based on temp.

I think that I have such good ventilation in the case that the path of least resistance was through the grill rather than the 80mm fan at low speed.
