As expected, such powerful components inside the P157SM lead to a lot of excess heat and thus high noise levels - as it is the case with most barebones made by Clevo. Sometimes, the fans turn off all the way while the system is idle, but there are also times when the laptop gets rather loud (~ 37 dB(A) from a distance of 6 inches) despite having nothing to do.
That is not only annoying, but also completely necessary - especially the fact that Clevo hasn't thought about introducing more levels of fan speeds. It basically feels as if they are either off or set to maximum speed. We do sincerely hope that Clevo will optimize the fan control system before the customer version is released.
Less can be done about the noise emissions when actually in use. 44 dB(A) during the 3DMark 06 benchmark are on par with other configurations such as the P150SM (~ 42 dB(A)) or the P177SM (~ 46 dB(A)). Under full load, e.g. during demanding games, the One K56-3N2 gets up to 50 dB(A) loud, something which can only be tolerated when the speakers are turned as far as they will go or when headphones are used..
