BTW the whole heat issue is kind of a moot point anyway, because that heat wouldn't be inside your case(except for an extremely small portion transfered through the metal), as the fan blows out unless you have an old PSU.
good point, i still dont like it down there though, never will

Also a cpu would be the surface area of the heatsink - the loss between the core and HS(as is the case for a psu), design and also materials would also play a roll in the equation. I can't tell you what the equation is or what would be the end result, because that simply wasn't the path that I ended up on.
Equation for conduction
Q=k*A*(delta-T)
the equation for convection is:
Q=h*S_A*(delta-T)
heat flux:
q=Q/S_A
k- conduction heat transfer coefficient
A- crossectional area
S_A- surface area
delta-T - temperature difference
h- convection heat transfer
Q- rate of heat transfer
q- heat flux
k is dependant on material properties (i.e. copper or silver has a way higher k than say steel or ceramic compounds)
h is dependant on the fluid's density to viscosity ratio, fluid velocity, specific heat capacity of the fluid, and the 'characteristic lenght' of the geometry (in most cases the fluid is air, but also water or antifreeze, etc). the primary reason water is better than air at cooling is because the specific heat capacity is much higher as well as the ratio of density to viscosity.
i dont see how this has to do with what we were talking about, but i'm bored.
