I have a question about the fan-system and especially the two air-channels towards the CPU and dGPU of my 2011 and 2012 MacBookPros:
Is it so that BOTH fans cool the same way first the CPU and shortly after the dGPU by a COMMON air-channel
OR:
are the two fans functionally separated - so that one cools only the CPU and the other only the dGPU?
Background of my question:I use macFanControl and want to be shure that both separatly adjustable fans will BOTH TOGETHER blow the air in a COMMON air channel to cool the CPU and dGPU.
If they´d cool separately I´d need to know which fan cools which processor....
Both seems possible for me:
the air channel leads first to the CPU and after that to the dGPU.
if a common cooling channel: Would be a sort of redundancy in case of one fan failing, but would cool first the CPU and after that "cool" the dGPU with already heated air --> disadvantageous for the dGPU which might explain a little bit the typical Problems with the dGPUs...
if separated: would cool both processors with cool air but kill rapidly one processor if its own and only fan fails.
Thanks for answers in advance...
