![]() ![]() But the CPU turbo boost mode should be used only for very short periods of time, not all the time like it does here. It is probably handled directly within MacOS, therefore Windows is lost and keeps using 100% of the maximum possible CPU frequencies. My guess is that Mac motherboards do not handle the turbo boost mode of modern CPUs. 20 Macbook Pro for my part) were overheating so much (reaching 100☌ on both models when fully stressed) with Windows (installed with or without bootcamp), I finally discovered why: ![]() As such, I want these fans to match speed to optimize airflow, and that is why I am using the coolant temp of the H150 to control the fans on the Commander Pro.After almost 8 years of wondering why Mac computers (e.g. The H150 attached fans are the intake (push), and the Commander Pro are the exhaust fans (pull). I also have the Corsair H150 AIO cooler, which has 3 fans attached:įans 1, 2 and 3 of both the H150 and the Commander Pro are attached to the radiator of the H150 in a push-pull configuration. So, this issue seems to change which fan is impacted, and how much that fan is impacted.Īlso, for clarification, I have the Commander Pro with 6 fans attached: However, fan 6 is 200 RPM slower than the others.Īlso, I have the 3 fans attached to the H150 set to 100%, but Fan 1 on that is also 200RPM slow. Fan 1, 2, 3, and 6 on the Commander Pro should all be about the same speed. Right now, I have all fans set to 100% again. Also, it's not always fans attached to the Commander Pro either. Do they all go? If you set it to fixed RPM above the maximum speed (say 2000 rpm), what happens? If all good, recreate your curves and trash the old. Immediately create a new custom "cooling mode" and set max to 100%. This will remove the current profiles as they are now on the desktop and put you back at the Quiet Preset, which is not so quiet. The fans will go crazy for a minute until you relaunch iCUE. Cut the configuration file from there and paste it to the desktop. Go to your C:User/(name)/App Data (hidden)/Roaming Corsair/Cooling folder. If the slow fan(s) changes between #1-6, it might mean the cooling profile is corrupted. Obviously the max speed test should result in relatively even fans speeds, except maybe 100 rpm less for radiator fans. It looks like you already use coolant temp as the control variable on the C-Pro and that is a much better choice. However, any Lake processor is going to be all over the place with CPU temp and activity, so it makes for a bumpy ride. The presets are linked to CPU temperature since that is the only thing guaranteed to be in every system. ![]() Is it always the same fans that lag behind (Fan #1 never makes it past 1000 rpm)? Or does it change?ĭon't use the C-Pro presets (Quiet/Balanced/Extreme) for testing. The third is running only three of the 6 fans at an elevated profile, but still one is basically idling. The 2nd is using the built in "Extreme" profile. The first is using the Manual Max mode I created and described above. I don't think its a power issue or something like that, because even if I only try to run 3 of the 6 fans at their max setting, the one still lags behind the rest. Even using this profile, one or two fans will stay around 800-1000RPM while the other spin up to 1400-1800RPM (which is also odd that there is such a wide spread of RPM speeds, considering all 6 fans are the same). I have even created a profile called "Manual Max" which does exactly what it sounds like statically sets the fan speed to Fixed 100%. However, even when all 6 fans are set to the same profile, one or two run very slow (800RPM). Since all 6 fans are identical, I would expect all 6 fans to perform similarly (RPM wise). Right now, I have 6 120mm LL fans connected to the Commander Pro. This happens both with custom fan curve profiles, or with the built in profiles. On occasion, random fans will not follow the fan curve properly. ![]()
