As far as the TC sponsorship, not even sure about that, and have my doubts.
There is NO sponsorship deal between ThermoChill and XS. I was a member on XS long before ThermoChill ever existed, and have remained one since ThermoChill was founded.

I have seen those stats and I find it funny that they were made BY Thermochill
ALL testing on ThermoChill rads was done INDEPENDANTLY. The only testing done by myself was comparative of PA Model to PA Model and included NONE of the competitions' rads.

http://www.thermochill.com/PATesting - all tests done independantly by BillAdams of Thermal Management Testing - the guy who DESIGNED the Swiftech MCR series of Radiators, and the Coolingworks radiators... so highly doubt there's any bias going in ThermoChill's direction there.

Bottom line, find your own facts, don't trust what people say here. That's what I did and i'm glad that I did
Obviously the "facts" that you found weren't "facts" in the slightest *shrug*.
