The system has two fans, the CPU temperature regulates the left one, the GPU regulates the right one. At high temperatures, both get very loud. In addition, the fan settings of the automatic mode at a given temperature are somewhat lower than in overclock mode, in particular at low temperatures. The difference between overclock and automatic is mainly a slower hysteresis (high pass filter) in the control logic, so it does not spin up fast at load spikes. The modes overclock and automatic seem to apply a fan curve that is defined in the embedded controller (EC), which is exactly the way I would it like to be. The main difference is between the fan modes (Full, Overclock, Automatic, Custom). They mostly apply different default settings. The settings Quiet / Multimedia / Performance in the ClevoControlCenter have little influence. I tried to reverse engineer the fan behavior as far as I could. I made some progress so far, but I am not fine with the result yet. Obviously this is not relevant for overclocking, but I assume everyone is not constantly running games with headspeakers, so noisy fans are a major design flaw in my opinion. My main concern however, is to operate it in a silent mode when idle, and from that perspective it totally failed. I player around with the clocks only shortly, and can operate the CPU at 4.2 or 4.4 with all cores in prime avx staying somewhat below 90 deg, so the cooling seems to work pretty well. It is an excellent compromise as a desktop replacement and the powerful hardware can easily handle workstation load. In particular, I am still not satisfied with the fan noise, so I am glad for any advise.įirst of all: I like the system very much and also Linux runs pretty smoothly. It took some time to aggregate some information of the hardware behavior, mostly from this forum, nodebookreview, and some other, so I hope it might help sum people to summarize my findings here. As I am using the system mostly as workstation (besides some gaming), I am a bit annoyed by the noisy fans and for several projects I need Linux so I set up a dual boot configuration. I am proud owner of a new Clevo P775DM3 laptop with 1080 gpu and 6700K processor.
