I was planning on selling this new 80mm Tt fan rated at 37cfm but instead I decided to put it in my 470w Noisetaker PSU thinking the fan on the PSU was made quiet. When I installed the fan it was running just as slow as the other one but right when I turn on my computer the fan is at full speed for 1 second and then goes back to the slowness. What I want to know is how can I make it run at full speed? I tried adjusting that knob that says H and L but it doesnt do a damn thing and never did before. Is that switch broken or is the H and L difference only supposed to work just slightly?
