wait, if the PSU is at the bottom, heat rises so.... even though its in its own chamber, its aluminium & will conduct the heat, same with everything else, the heat is conducted EVERYWHERE VERY QUICKLY, there within some of the basic principles of science my lie your answer
Sure heat rises... But, in stagnant air.
There are 3 fans in the bottom chamber.
FRONT - Brings fresh air in, across HDD chamber
MIDDLE - Brings air to the PSU chamber
PSU - Exhaust warm air out the rear.
So it's one constant airflow, from front to rear.
Heat is prevented from rising, because the air isn't stagnant.
The Middle Bottom fan isn't even needed to tell you the truth
There are three types of Heat Transfer
RADIATION, CONVECTION, CONDUCTION
Radiation is transfered energy in the form of waves. Example would be the sun beating down on balck aspault in august. That mirage you see is radiation. Heat dissipating from the aspault into the cooler air...
Conduction is heat transfer by means of molecular agitation within a material without any motion of the material as a whole. A good example of this is your CPU CORE > CPU IHS > THERMAL COMPOUND > HEAT SINK. This is an example of conduction.
Convection is what is happening in the bottom portion of the case, cooler air is mixing with warmer air and the fans remove most of it from the case.
