    True to its motto "innovate - don't imitate," Thermalright consequently improves on the original cooler concept and implements suggestions by their fan base. The result is a further optim...

    The original TR Macho was a great-performing and affordable heatsink/fan combo. I hope this one won't disappoint, but I can't see a fan on the picture.

    it's 870grams not 1.870... I hope:bang:

    it would be nice if someone would actually not cheap out and make the fins also out of copper not just the heatpipes. Copper conducts heat better than aluminum. Bet we would see some nice gains with a pure copper tower heatsink. Imagine how good the noctua nh d-15 would be if it was entirely copper because it already performs amazing.

    Thermalright used to make such coolers - before heatpipes, and after heatpipes appeared, eg Thermalright TRUE Copper. The difference in performance with heatpipes was minimal and not worth the extra weight and price.

    FYI: Copper conducts heat better than aluminium, that is a well established truth. And is why the base and heatpipes are made of copper. Their function is to spread the heat from the small CPU die, to the very end of the cooler. The smaller the loss, the better. (you want the largest delta-T between the ambient air, and the cooler)

    The fins on the other hand, is to spread the heat over the largest possible surface area. This will radiate a little more heat, and more importantly, to more efficiently convect more heat to the air.

    But here is the problem: Air is an insulator, and a extremely poor conductor of heat, with pretty poor heat capacity as well. And the aluminium will have absolutely NO problem conducting the heat from the heatpipe and spread it around the pins with almost any losses (becouse of the slow convection).

    You could with a better conductor, make the fins smaler and space them tighter together. But in real lifte, that would only make the radiator too thight for air to efficiently blow through the cooler.

    That is also why you in most cases see a pure copper-block in watercooling applications. Water have a excellent heat capacity, and good conductivity, and have enough, but not too much viscocity, to be efficiently pumped thorugh extremely tight fins/pins.

    The weight and price of copper also makes it a less good choise for a huge cooler, and it's oxidation is much more apparent (will quickly loose it's good look, and make a thicker "insulating" layer).

    So that's why folks, forget about the idea of using copper fins in PC-cooling applications. You won't see copper beeing used on the fins in even expensive heatpumps (which is a huge thing in Norway) or in airconditions either.

    Coolers that DON'T use heatpipes/water or any other efficient way of conducting the heat away from the base, would probably benefit using copper-fins. :)

    Edit: A passively cooled cooler like this one , would benefit even less from using copper-fins, becouse of even slower airflow/convection.

    Some Zalman coolers are 100% copper.

    Yes. I even own one. :) Or 99 % at least. (becouse heat-pipes ain't solid copper)
    And you can also find it in a few water-radiators.

    Not that it should matter. At least not if you designed it well.
