I don't see any mention of durability of these pads vs. Yellow Kings, nor of comparison of wear they induce on rims.
On the other hand the yellow pads became a bit outdated compared to for example the much cheaper blue Reynolds pads (I use them and they perform way better than both the yellow kings and the black LW swisstops).
it seems this is just a single braking event, if the temperature is for the pad surface, it may simply be that the new pads have much better thermal conductivity, so they'll sink more heat into the holders/calipers and reduce the rate of temperature increase
This will take some weeks. Until that only the Lightweight by Swissstop pads are allowed for Lightweights wheels to avoid a loss of warranty.
And that they will not higher priced than the already costy yellows.
Like sharkman said the Reynolds blue are performing better than the SS yellow.

Some companies pads wear faster and shed material (without building heat) in the process of stopping better, some have a bit more surface area and some use material that simply doesn't conduct as much while the surface maintains or increases the friction / stopping power.
The better newer pads from a few companies are a combination of these things.
Higher stopping power/ friction doesn't have to equal "more" heat than pads that doesn't stop as well...
That might be correct on quality pads compared to really old fashioned stuff or pads that aren't up to the job between good pads there als only marginal differences (so more stopping power has to come with raised friction and more heat).
I think what Carbonsports is trying to tell is that if the Swisstop claim is viable (more stopping power with cooler pads) the heat has to dissapear through the holder/brakes and rim and testing is the only way to see if the claimed better performance doesn't come at a price.
The yellows were good relative to other pads but different compounds in the last couple of years came into play that could both brake better and, yes, create less heat at the rim (and not melt and lay a coating onto the rim, which the yellows would do under fairly extreme conditions)
Carbon sports is no different than every other quality rim maker looking for (and finding) that compound / material selections have improved.
Different rim makers have different concenrs though and it's down to rim construction difs. Zipp did a better job with resin and their rim simply doesn't heat up as much as many others, but the surface has a different texture than many. A few other rim makers are using coatings... Some are just looking for better pad compounds. All are finding better solutions but it's not a "one pad for all" solution...
