soopytwist Posted March 6, 2013 Share Posted March 6, 2013 As mentioned in other posts I now have two SP120 Performance fans on my H100i using the volt reducer wires to quieten them down. I ditched Corsair Link because it won't control the SP120's, this means I have no control over speeds - they are what they are. Not even Asus Fan Xpert+ can control them because they're not 4-pin fans. Every time I boot my PC I get different RPM readings from the fans. Just now after booting up for the first time today the RPM for both was barely over 1000, which may explain why the CPU temp shot up to 40C on idle and the motherboard about the same. Again, can't change speeds myself. Rebooted and now they're both 1200 RPM and CPU temp is now 28C and motherboard 37C. So why the change in speeds? Presumably the change is in the voltages, why change at all? Link to comment Share on other sites More sharing options...
