In some cases, pun intended, that's actually not a good idea.as
with some cases, that is true.
With an enclosed space, it's supposedly designed to force airflow
across the whole board (yeah, we know the cards get in the way).

in what i would estimate to be at least 90%, if not 99%, of fans
set up by oem, fans flow air out of the case, not into case. as
such, there is very little airflow distributed anywhere near what
could be considered properly across board and components.
kind of like oems know that airflow is not adequate and they are
hoping for heat failure so they can sell newer and more systems.
I rather like the newer cases that have a big, slow, quiet, fan,
mounted on the side panel, that blows over the whole board.
yes, mounting fan on side panel is better as it does allow for a
larger fan. as for speed, i am hoping that the new fans are
variable speed and controlled by temp sensors around memory and
vlsi chips to increase fan speed when needed.
"sensors" is a great routine that many need to learn to use.
tho i do wonder about it sometimes and now is one of them.

i do not know where/what 'temp4' is reading, but it tends to
show a rather efficient heat sink. :-D
