ACX of the current situation is GPU is certainly cooling.
However, the PCB(MOSFET,VRAM,VRM) is not cooling.
This is because, from the heat sink until the MOSFET is because it is full of gaps.
This problem is a problem that occurs in ACX fan all of the product.
It will not rise in temperature to dangerous temperature depending on the product,
but, Since become a high temperature state that is shorten the product life cycle,
such that no doubt I think immediately should fix this problem.
WARNING: summer is also when the Room temperature is in the MAX 40 degrees in my environment.
Physically air conditioning can not be installed.
But, I can be feel cool in the spot cooler.
However, PC is not cooled.
In this way, do not forget that they using in a specific environment.
sorry bad English.
