On cooling

Case side-panels have to be the biggest obstacle to cooling.
My temps were 9C lower with side-panel off (Globalwin 802) - so I fitted a
9"-square, louvred, plastic vent to it (bottom/rear).
And cut out the chassis' exhaust grille.
Temps dropped 7-8C, from 45/66C to 38/54C - only 2C above panel-off temps.
Do it now!

QED, eh ?

Sorry if I get the balls to mod my case I'll put 92-120mm exhaust fan on the
top.

I found that removing the top (/side) panel of the case made little
difference to temps - I guess because with the 'access' side-panel blocking
the flow, there is still little bulk air movement.
Once that blockage is removed, there's more than enough throughput out of
the PSU and exhaust fans.
You can get away with very low CFM/dB fans if there's sufficient
non-impedance of the bulk flow.
I now have -

PSU cover removed.
All grilles, blanking slats and guards removed.
With 2 CPU, 1 PSU (obviously), 1 VGA and 1 exhaust fan - all of which are
19CFM/12dB.
