Do you have CPU throttling while using GPU Nvidia 940MX in the Notebook 9 2017 NP900X5N?

    I noted a significant frame drop while Playing Battlefield 3 in FullHD with high settings after about 10 minutes with the Notebook 9 2017 when I use the built in dedicated Nvidia 940MX. The temperatures in HWMonitor say about 92°C for the CPU and around 60°C for Nvidia GPU. Case Temperature ist about 75°C. So the GPU is fine but the CPU cores are above the limit and throttle down to 50% duty cycle while keeping core frequencies high.

    Does somebody have similar issues or is it my unit? Can you test with a game or some programms that stress CPU and GPU at the same time and read the temperatures with HWMonitor after 10-15 Minutes?

    As a result the FPS in Battlefield 3 are higher while using the internal Intel Graphics unit instead of the dedicated GPU. There was no a similiar throttling while using only the Intel GPU. The CPU Temperatures in this case are high too but stay constant around 89°C.

    Unfortunately the fan speed can not be read by HWMonitor but I think the speed is too low for the given temperatures. The fans stay relative quiet in this high demand scenario. Of course silent fans are one of the main reasons to buy samsung notebooks but I'm not sure if it has to be like that.

    I am wondering how accurate HWMonitor is? I think it can be off sometimes. I can try a test on mine, I have never checked the temps.

    Try to repaste, use cooling pad, tweak bios or contact samsung to know how to get your fanspeed max!
