Personally I never play Furmark, I found it a very boring game.
The fun games out there result in far lower VRM temps. PLus the VRM's are rated for 125C anyway.
Doesn't seem right that the coolant in the card also seems to be just as hot. Also, isn't that shot from the "top" side, as you can see where it says Radeon?
100C water would not be ok. It would be boiling and spraying over the case. So that website needs to be sued for libel
It isn't plain water, so it probably has a higher boiling point. And even so, where would it spray from? It's pressurized. Unless you are implying it would blow a gasket some where?
There have been no reports of it getting that hot though. Well, except for this one and I really doubt there's room for the expansion that would occur if it really got that hot.
The story changes during our stress test. The water-cooling rule of thumb comes to mind right away: use one centimeter of radiator length per 10W of power. Almost 90 °C at the motherboard slot indicates that the VRM pins have passed 100 °C. This certainly isn’t a great way to run the card long-term, but then again, stress tests aren’t an everyday usage scenario. Still, it would have been nice to see some reserves for overclocking.
EDIT #2: Leaving this post, but just realized the discussion was about two things, the coolant/radiator and the VRMs. The bottom is about the VRMs which supports the French website, as for the coolant/radiator - I'd wager if Tom had removed the soft plastic cover they'd have similar findings to the French website. French website didn't include a shot of the radiator though.
There have been no OTHER reports of it getting that hot, but I also don't think other sites were rushing to test Furmark.
It doesn't invalidate the data from this site, it just makes it irrelevant without collaboration.
EDIT:
Here is Tom's supports VRM's hitting over 100C during their stress test, so there is collaboration.

I'm not realy doubting the VRM's reaching 100°C running Furmark. I'm doubting the cooleant reaching 100°C. 100°C for VRM's isn't a problem like people try and make it out to be. Plenty of cards have run hotter than that and been fine.
I can't find the URL for that French website, and I agree with you. No way the radiator is any where near 100C.
I don't think the French site included a shot of the radiator, anyways.
I'm talking about this shot. It's showing the tubing inside the card and even the power connections being the same color as the VRM area, which they are claiming 100°C. Not talking the rad.

Wish somebody would just post the part number on the VRM's so I could look them up. I still do not think 100C is an issue. Even if they 125C rated VRMs, 100C is exactly 80% of that, which is within the advised long term safe zone.
This help?
The VRMs are
CTX01-19369
11PH15A

Those aren't the VRM, look closely at the full cooler pictures, they're next to the copper cooling pipe. Seems to be inductors or capacitors maybe, not sure since I'm not an electronics guy.
Looking at the other board pictures without the cooler the VRM seems to be IRF 6894 with the following datasheet: http://www.irf.com/product-info/datasheets/data/irf6894mpbf.pdf
Tj max seems to be 150 degrees celsius (page 3) so 100 degrees is well within the operating range.
