Recommended Posts

Dont know if anyone has ever covered this , but what about stacking heatsinks ... ???? seems logical doesnt it? Love to hear some opinions

does and it doesnt..

 

sure if you have to copper heatsinsk on top of each other it will be cooler.. just because it has more area of cool ness.. but to keep it cool.. u would have to have either a biger fan.. or a more CFM Fan to keep this extra area cooler.. but who knows..

There is likely little-to-no advantage in stacking heatsinks in this fashion. It really depends on the heat sink. Generally speaking, increasing the total surface area will help to dissipate heat more effectively but unless your current heatsink is already at its limit in this capacity, increasing the surface area will have no effect. For instance lets say your heat sink is dissipating 50 watts of thermal enegry but can handle up to 60 watts effectively. Why increase the surface area if you arent already pushing 60? See what I mean?

 

Psywar brought up an interesting point that in if you do somehow get the increased surface area to draw more heat you still have transfer the heat from the copper to the air, i.e more fans. Like the hurricane in your case isnt loud enough huh? :) I also agree it would probably only be effective if the heatsinks were essentially two identical solid blocks of copper (lapped surfaces w/thermal compound between them couldnt hurt). In that case you would be increasing the exposed surface area by 80%.
