Hello, I recently purchased a Surface Book 2 i7 256 GB 13.5 inch with the Nvidia 1050 GTX. I was very excited with this device until I noticed the first problems. The screen is a little bit bent at the right top corner and as known this devices suffers from the coil whine issue, but it worked great. I tweaked some settings with Throttlestop to get rid of the coil whine and now it's almost completely gone (and losing just a little bit performance). A few days ago I noticed that when I left a program running on the dedicated GPU with the setting changed to high performance in the Nvidia control center, the fans stopped spinning while sleeping but on resuming the system they started spinning on max. I checked the temperature of the GPU and it reached as high as 87° C. This doesn't seem normal to me. I did some more tests and always got the same result. It seems that when sleeping or when the screen is turned off without sleeping (by disabling the connected standby in the registry), the GPU keeps on running with a high clock speed even when there isn't any demand by the application. This only happens when the settings is set on high performance in the Nvidia control center, otherwise it will lower its clock speed. Normally this shouldn't be a big concern, but it really gets a problem when the surface book decides to turn off the fans of the GPU. The temperature rises until it reaches the limit and then starts throttling and keeps on doing this until the surface book is resumed from the sleep or screen off state. Does anyone have the same problem? Is this a setting in the BIOS or is it adjustable in the registry? At this moment I disabled sleep and screen off completely, because I don't want to ruin my GPU.
