i have a Mad Dog Multimedia PSU in my latest build. it is made out of all used parts, which im proud of!

mad dog multimedia 350w PSU zy35wpsg-d is what it says in the corner of the sticker, i assume its the model #
so the question i have is abouth hte PSU. on the back, next to the fan, is a button asnd 3 leds, a blue one that says A next to it, a green one that says S next to it, and a red one that says T next to it. prssing the button changes which led is lit up. when the blue one is on, the psu is kind of quiet, on green its nearly silent, and on red its rEALLy loud. im not sure what this does, but i usually leave it on the blue setting. AApparently, according to the sticker, the PSU has a thingy where the fan goes faster when the temp is higher. however, the fan speed never seems to get faster/slower while its on the blue led setting. Blue was the sefault setting, and thats what i usuakky runit at. the ANtec PSU calculator i used recommends my computer to use a 275 watt pSU.
my question is, what does the button do? is it simply afan speed controller, or does it actually change the PSU's behavior?
AW GEEZ! Those CompUSA housebrand power supplies were made by a Chinese company that had a very bad reputaion for low budget, low quality, power supplies of questionable performance and value. I just posted about that recently. They also made the first Ultra modular power supplies that had all those problems. Ultra now uses other manufacturers.
