Is there any point??

Yeh, your alternative mod seems much better than Akasa's, market it you would make a killing!

Quite a few cases take the no airflow approach, or very little airflow.

The upcoming Lian Li S80 is a prime example, at low noise not more than 10cfm would be moved in the main compartment looking at the airflow diagrams, why I am so excited about it.

Many ways of cooling, high CFM is only one, if you run a hybrid system of water and air like me, then you dont have the heat from the CPU to worry about, and I have no airflow bar its HSF on the graphics card, yet it cools very well.

It is system dependant, and yours must benefit from the padding but I know in my rig it would shoot up the temperatures, virtually instantly from boot.
 
I wonder if the Akasa stuff is limited to certain case types?

Probably not in desktops, the egg box foam would mess with the airflow across the top panel, and the case layout tends to impinge on the flow across the m/b

Probably not in HTPC rigs, again desktop format, but the airflow is lower. If there really is air-to-case heat conduction going on, then it would appear here where the air stays longer inside the case and so has time to cool via the metalwork.

Tower cases would seem to not suffer, I’d guess due to the airflow being just a diagonal across the case, and hence has an easy passage out

Thanks for the heads up on the Lian Li S80, that’s a nice design
Here the air flow link:

The “box in a box” method has been a long time coming, and hey - rubber door seals! :D

It occurred to me the pro/con of panel dampening can be tested, I would need an (idealised) aluminium box, and test the stable heat at different air flow rates.
I’d guess there would be a point (at really low CFM) at which case conduction becomes a factor. Then re-test with different types of insulation. Wonder if Akasa would send me a sample? :p

Another factor >might< be infrared radiation from the CPU; this would be affected directly by case insulation, (unless the CPU is ducted)
 
Must be 2 in a 1000 as mine hasn't risen by even a degree. I took readings before and after and it was the same, even after 24 hours it stays at its normal temp. If i close my bedroom window and turn on the heating it goes up by a few degrees as normal so its reading temps OK. I found it helped to stiffen up the panels and stopped as horrible noise that i couldn't pinpoint. There are other ways and cheaper ways but like i said i got it really cheap from a mate. The temps arnt affected in an eclipse62 with both fans at 5v in my experience. I wouldn't recommend it though as it doesn't stop fan noise that much and its very expensive for a few sheets of foam.
