Except that comparing an AlphaCool 1080 to this would be roughly like comparing a 120 radiator to a 360 radiator.
AlphaCool 1080 surface area: 360mm x 360mm = 12,960mm²
This monster: 600mm x 600mm = 36,000mm²
And the thickest, bad-assest AlphaCool 1080, the Alphacool NexXxoS UT60 Full Copper 1080mm Nova, is only 60mm thick, vs 75mm on this thing, for 25% additional girth. I would be interested in comparing the fin density between the two though.
There is a reason the AlphaCool weighs 3.7KG, and this thing 15.9KG. Fill this monstrosity up to capacity with coolant, add a grip to it, and you could use it for weightlifting.
I'm not saying the AlphaCool isn't ridiculous and badass, it just isn't punching in the same weight class as this monster. Literally.
