The common tools (msi afterburner, fanspeed, hwinfo, etc.) fail for this clevo Model. ![]() So the fans are controlled via the EC, there seems no direct control of the fans the software. (For reading the fan RPMs: the hwinfo64 tool can read it for some clevo models ( ). I'll probably repaste the GPU when I find some time, but currently the warm GPU is actually convenient for tuning the system.Īnyway, this 50 deg GPU makes the fan always spin fast (at around 3k RPM), so the system is constantly loud. I would actually be interested in other people's idle temperature. Pascal is very efficient and in idle mode I would not expect it to drain much power. I am actually wondering why the GPU gets so hot. Running idle, my system settles at around 35-40 deg CPU temperature and 50 deg GPU temperature (at 20 deg environment). Perhaps that is why the standard fan curve tries to keep the card below 50 deg (see below). There is also some throttling when the GPU gets warmer (starting way before 90 deg). Perhaps the linux pstate kernel driver is interfering with it. I don't know how the throttling is implemented. On linux, the CPUs will constantly stay at full clocks if both CPU and GPU are under load. When the GPU is used, CPU clocks are throttled. I also observed some throttling that was reported by PREMA before. ![]() (In particular, it seems to me it does not cut the CPU clocks itself, but lowers the power limit.) Anyway, that fan curve might actually work well (system is silent even at 50 deg GPU temperature, fans spin up at really high temperatures), but I have no idea how how to activate it with PSU. When the system runs on battery, it seems to use yet another fan curve which is really silent and it dramatically cuts the clocks to around 2.4 GHz for the CPU. I would consider that a bug of the ControlCenter. After a reboot or suspend/resume, the fans revert back to overclock mode, even if I set them to automatic before. When I define a fan stop below 60deg and fan active at 70deg (centigrade), the fan starts to spin at around 55 deg, cools down the hardware to around 48, then it turns off again until the hardware has reached 55 again.īecause in a fanless mode the hardware reaches 55 in little time, this is no reasonable modus operandi, in particular because the fan seems to spin up fully for a short time when it sets in. It does indeed stop the fan completely at low temperatures, but start and stop temperature are related (but not identical) to what I set. The custom mode lets me define a start and stop temperature for the fan, but essentially it is not working as intended. In both cases (automatic and overclock), the systems gets really loud starting from around 50 deg. 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.
