Even my “corporate” Thinkpad with no dedicated GPU has all the fans on the bottom and exhausting to the sides and back.
With the new hinges there’s space on the back for exhaust, some impeller fans drawing from the sides and exhausting out the back would be so much better. I custom printed some 1/2 inch high feet so it doesn’t throttle sitting on a table or lap desk because it’s just a terrible design even when used normally
