Probably near the top, between the cpu and memory, closer to the
cpu RM ( mounting bracket)...This can be a problem area due to the
fact that psu heat my radiate down and also just the fact that the psu
bulk will trap heat in that area as well.
On my board, the psu is very close to the mobo and although I have
a dual fan psu, heat still gets trapped here. The way I solved this
was to mount a 120m fan blowing in from the side cover (clear side,
fan with led's...). This fan is controled with a switch and a front
mounted speed fan control. The cooler outside air (filtered) blows
right above the video card, over the north bridge and most of the
memory modules, plus it feeds cooler air over the cpu fan, also a 120m
led on a speed fan control. The psu intake fan draws from the cooler
airflow right over the problem zone and mobo temps stay very
resonable, now.
Just having that cool air coming in has made a remakrable temp
adjustment in my system and even though I run overclocked @ +12.5%, I
only need to "switch it on" while running 3d intensive games, where
temps start to really take off.
About the new computer desk...? The oven is on and the door is
really closed. That encloser will definatley make short life of
computer components...
