I will says this just one more time and then I will drop it, the MS has bits crammed in like the engine under a mini bonnet (hood), in an ordinary PC there is usually plenty of room in front on the CPU fan for the cooling air to straighten out and then get out via gravity or via a second side case fan, even water cooling has been introduced for some big CPU. The CPU cooling fan on the MS blows straight into the top case which looks about no more than 50mm away this is not good, why because some of the hot air from the fan will hit the top of the case bounce around and then go back into the air intake fin on the CPU thus increasing the temperature. The results of building electronic bits sat close to each other has it’s payload in warming each other up and most PC components are usually rated at no more the 40/50⁰C. If I was designing the MS the MB would be in a separate mini tower with a flying lead make the KB much lighter to handle and last forever. The MS does look a nightmare to work on, let’s hope that nothing goes wrong inside. There are thermistors on all MB PCB now and this should have been flagged up if it was a problem so perhaps it isn’t.
