Sorry, I meant vapor chamber.When i said cooler i meant fan. The FTW uses a vapor chamber style cooler.
And the stock 670 doesn't have it:
The plastic casing of the cooling system is fastened along its edge. It is quite easy to remove.
It hides an aluminum heatsink on the power components, a GPU heatsink and a fan secured on the plastic extension of the PCB.
The GPU heatsink consists of a copper base with aluminum fins soldered to it.
There is no vapor chamber and no heat pipes here.
The reference GeForce GTX 670 cooler also includes a simple 70mm PWM-regulated fan and a tall heatsink for power system components.
The unsophisticated cooler, short PCB and rather simple power circuit do not quite match the product's price tag of $400, but that's what Nvidia offers for that money.
