You will be happy with the cooler on the AMP Extreme. One of the coolers I have ever seen. Much better than the one on my G1 Gaming. The only problem you will likely be faced with is fans reving (unless they finally fixed that issue in BIOS), but it can easily be fixed if you just make your own custom profile on afterburner.Still got the Amp Extreme on an early Amazon payments pre-order at OcUK for £809
I wonder if the cooler on the AMP Extreme 1080Ti is the exact same as the one on the 1070 or if it is an even bigger beast. If the same, it obviously won't be as quiet as my 1070 was due to all the extra heat.
