MadHacker, that's not the right question. The right question is what is the C/W of the radiator. Then, you can say that for an acceptable system (CPU, etc...) temperature and a given ambient temperature, you can dissipate X watts of heat.
For 4C of dT, and 70W of heat (a SWAG of idle CPU, NB, and GPU heat output), that'd work out to be a C/W of 0.057 for that radiator. Insert your own guesses if you don't like mine which are wrong and probably give the passive radiator too good of a C/W rating. But, 0.06 C/W is probably in the right order of magnitude (the real C/W is probably more than 0.006 and less than 0.6).
So if that guess is nearly correct, if you don't mind 10C of dT, you could dissipate 140W of heat, etc....
