Hi techies, I have a PC with a Prescott Processor, two hard disks, 2-Optical drives and the temperature inside my system varies depending upon the time. What I mean is, if its night time the temperature is normal and during day time the temperature is high inside the cabinet. I have 2 fans in the cabinet for cooling. These 2 fans produce lot of noise as I have connected all of them to the SMPS 4 pin plug for maximum speed which in result gives more cooling. But my problem is that, in the night even though all the fans are top speed the temperature is same, the fan's maximum speed is useful only during day time. Because of the fans running at maximum speed they produce a lot of noise. My motherboard has a "quite" feature by which it can control or vary the speed of fan. That is if the temperature is high then the motherboard can increase the speed of fan else it can reduce the speed of fan there by decreasing the noise. But this can be done only with a fan which has both speed monitoring and also its speed can be varied. This type of fan come with a 3-pin plug [Speed,+12,GND]. But these fans are not available in Chennai. Can anybody suggest where this type of 3-pin fan can be purchased in India? Antec markets their cabinet fan. But the problem is that their fans take power from the 4-pin plugs and have one pin which sends out the speed of the fan. So there is no way of controlling the speed. So Antec is of no use. I would like somebody to please give me the address of a shop in India which sells this type of fans. I live in Chennai but please give me the address from anywhere in India. Thanks, Kannan.
