"Toggling the “Turbo / Normal” labelled BIOS switch on the PCIe bracket activates Colorful’s “one-key” overclocking, a feature found on their other cards. This adjusts the base and boost core clocks upwards as listed in the prior table."
A test of these yber water cooled 1080ti card would be nice. In this highend the water cooler can be actually practical because these cards definitely produce a lot of heat...
I doubt that the radiator and block design has more potential than slapping two insufficient fans on the side of the graphics card, they're effectively moving the exhaust.
Corsair AIOs and similar routinely drub aftermarket air coolers on GPUs. The GPU form factor is a prime candidate for liquid cooling loops because they don't have a good number of advantages that the huge CPU air coolers have.
Yes, it's not even close. Liquid cooling a GPU blows air cooling away. It's not the same as with a CPU. The problem with a CPU is the die is so small that there's a huge bottleneck in transferring the heat to the water block. The CPU might be at 65 C, but the water temperature is only at 35 C.
With a GPU the large die means that the heat is very effectively transferred. A 1080 Ti that would run at 65-70 C even with a massive air cooler can easily be run at 40-45 C even with a 120 mm radiator. Truthfully a 120mm radiator is more than sufficient for a GPU, a 240 would just allow for quieter operation since you could run each of the two fans at lower RPM.
For starters, those fans aren't trying to shove air through a PCB, they've got a clear exhaust route through the radiator. Second off, the thermal mass of the water isn't insubstantial and helps even out thermal loading. Third off, radiators have the water flowing through the fins, which is a lot better than naked metal fins with heatpipes kind of closeish as far as conducting heat into the actual airflow. Fourth off, the radiator gets the hot air out rather than leaving it in the case.
With all that, it's no wonder that smaller radiators on previous hybrid designs absolutely drub aftermarket air cooled cards. For reference, this sort of 240mm radiator routinely stacks up with air cooling CPU behemoths like the NH-D15, which has two better and larger fans than any video card on the market, clear air flow right out the back of the case in an ATX configuration, and considerably more mass of fin and heatpipe than a graphics card. In addition cooling a CPU means dissipating less heat than a GPU, so the higher noise floor of something with a pump is more relevant there.
The reasons not to go with liquid cooling on GPUs are expense, possibly the raised noise floor from pump noise vs. modern 0% fan speed at idle on current cards, and the fact that air is good enough and the liquid cooling failure modes are much more exciting than those for air, not that it isn't effective.
Is the 57mm thickness the thickness of the radiator by itself or the thickness of the radiator + fans? I only have 45-50mm to work with (haven't accurately measured it yet) at the top of my case and I've found some 15mm high static fans that I could use if the actual radiator is around 27mm like a Corsair H100i V2, but if the radiator's 57mm then it won't fit.

There seems to be a turbo button on the back of the GPU next to the hdmi out... Is that for the "one key oc" or something else?Nate Oh - Wednesday, July 12, 2017 - link
"Toggling the “Turbo / Normal” labelled BIOS switch on the PCIe bracket activates Colorful’s “one-key” overclocking, a feature found on their other cards. This adjusts the base and boost core clocks upwards as listed in the prior table."So, yes :)

That linked 4-slot design looks ridiculous...This one looks practical. Tacky, but practical.

You think dual fan air cooling is about as good as liquid cooling using a massive radiator.Ooook ...

Compare an air cooler compared to a Corsair AIO unit. Same thing here. That isn't a massive radiator, at best it's a 240.2 at 25mm...HomeworldFound - Thursday, July 13, 2017 - link
Just to point out.. that's the radiator dimensions... not the plastic around it as listed above.xthetenth - Friday, July 14, 2017 - link

Well, a 2-slot might enable the cooler to run the pump at a lower rate, right? And maybe the fans too.xthetenth - Friday, July 14, 2017 - link
Yeah, I like the idea of more fans at a lower speed.Gameskiller01 - Saturday, July 15, 2017 - link
