This Dec 2019 MacBook 16 needs to be silent, otherwise it is unsuitable for my work and not fit for purpose My old 2015 MacBook Pro was silent and cool when connected to the exact same external display doing the same light work MacBook very hot to touch above Touch Bar, at lower part of screen and underside close to hinge CPU temperatures often reach 90+ deg c with external monitor connected (usb-c to displayport)
Loud fans and high temperatures are experienced even during light work (only Chrome browser running with 2 tabs open) MacBook cooling fans are very loud and distracting when MacBook is connected to external display (2500 - 5500rpm) even with light loading (only Chrome with 2 tabs open) Please fix the GPU issue as this gives AMD a very bad image in the Apple community.įeel free to ask me any questions or contact me if you need any logs dumps or reports. This probably can be addressed with drivers being released as from other people's reports this does not happen on the same machine running Windows. General temperature also rises to above 65 degrees Celsius.įrom my research this seems related to AMD card locking higher memory clock speeds when 2 monitors are being used even if no demand is being required from them. Fans speed start increasing to between 2500-2800 while no activity is being done on the laptop. Open laptop screen, GPU draw rises to 18-20w idling (as in not running any applications), just staring at the screen.
With laptop screen closed GPU draws 5-6w idling and fans stay at base speeds 1700-1800 and temps below 55 degrees Celsius (ambient temperature 25 degrees Celsius). External Monitor: LG 27UL850 (have tried with another different resolution monitor, 1080p, same results)
