Re: Another guy with a fan speed/noise problem
You need to look at this in the PROPER context! IS is NOT a "fan speed/noise" problem; instead, it is a "processor overheating" problem.
The fans are designed to operate at whatever speed is needed to prevent the processor from overheating. The ONLY solution in this case is to throttle back the processor -- which is what the Jupiter app tries to do.
IF you forcibly slow down the fans, you risk either burning out the processor, or (if autotemp shutdown is enabled) having your PC suddenly shut down on you when it gets too hot (due to the fan speed being reduced).
