We're more than happy to disclose actual temperatures. Absolutely no secrets
The reason we've chose percentage changes is that we're comparing up against the former GPU Blower card that Alienware used, in their chassis.
Numbers aren't totalitarian, so you'll get different actual numbers depending on cases and setups. What we decided to do is eliminate that and focus on a strict A/B scenario.
I'm also pretty sure that there will be more content (from Alienware and Ourselves) on the Rad Card in the near future
This comment demonstrates what I expected.
Numbers aren't totalitarian, but mathematics and physics as we understand them work according to set rules.
The percentage is meaningless - not because changing test conditions or test variance - but because
the origin point is arbitrary. You can get wildly varying percentage values by choosing to measure temperature changes against any conceivable origin. You can have your pick of (at least):
- 0°C (80°C to 60°C yields "-25%" compared to the freezing point of water, for some reason)
- 0 K (80°C to 60°C, or 353.15 K to 333.15 K yields "-5.7%", compared to absolute zero energy state)
- room ambient temperature (like 20°C): this is the unreachable limit using air or water cooling (80°C to 60°C yields "-33%" of potential cooling)
- case ambient (maybe 30°C?): this is the unreachable limit using air or water cooling with the radiator fans drawing air from inside the case (80°C to 60°C yields "-40%" of potential cooling)
None of the above percentages mean anything. It's pure marketing talk.

EDIT: To add to the above, you can say it's "fine" to say 80°C to 60°C is "-25%", but let's look at the math that arises from using 0°C as origin:
60°C / 80°C = 0.75, so 60°C is 75% of 80°C.
0.75 - 1 = -0.25, so 60°C is 25% less than 80°C.
So far, so good, right?
Suppose we then choose a comparison point other than 80°C. Let's pick -1°C.
60°C / -1°C = -60.00, so 60°C is -6000% ("negative six-thousand percent") of -1°C.
-60.00 - 1 = -61.00, so 60°C is supposedly 6100% less than -1°C.
Not only that but there's a discontinuity at comparison point of 0°C (division by zero), so the ratio would be undefined - you couldn't compare 60°C to 0°C. As the comparison point approaches 0°C from the positive side, the ratio approaches +∞, but approaching the same from the negative side it approaches -∞.
Once percentage calculations using legal values start producing this kind of garbage, it's a pretty good hint that something is wrong. And what's wrong is that the origin is set in the middle of the temperature line.
