I think it's essential to stress that PC / Computer cooling industry needs to up its standards.

PC coolers unfortunately come with no documentation / measurements about their thermal characteristics.
Just take a look at
Say for example
This nice company actually states for this piece of heatsink:
Rth [K/W] thermal resistance
0.21 - 0.4
Obviously this is not a heatsink for cpus, but you may cool lots of other sorts of transistors on it...

The same goes for Fans. Just do your research and you will find out that every company has its own standards when it comes to measuring CFM / air flow / air pressure etc.

Thanks for the article!
