Hi and welcome. Sorry that I didn't see this post.
We can not simply disclose what is inside. I will email you on this topic and hope for your understanding.
We test the coolers based on around 130 W or higher, so when people say 85 W it is not our statement. The thing is that we want it to be working fine with 130 W if this is possible, but lower TDPs are still fine then.High end models are testd on an even higher TDP.
The design temp is a sort of a secret as well, please refer to my email there. Thanks =)
