@nikhsub: Well, I'd have to lie if I said I wasn't surprised by the TDX performance too.
My charts on a quad core platform do look different, but that's another story.

So, the platform I used for the test that's shown was a C2D 6600 with machined top, a Thermalright backplate and Arctic Ceramique as TIM (normally I use Silmore, but I ran out of stock on it ). The CPU was running at 3.833GHz with 1.46V, tested with Windows XP 64-Bit and the according version of Prime95.
The loop I used had a PA 120.2, Laing DDC+ with Petra's top, Swissflow SF-800 flow meter, a small water filter made by Mips, t-line and 7/16" Masterkleer with EK 1/2" barbs. I also used the Aqua Computer poweradjust to run the pump at 100% and 60% to simulate a lower flow loop (for people that like to use smaller tubing or a GPU block in their loop for example). Water temperature and room temperature was recorded of course, throughout the testing the room temperature stayed within a range of ~2°C (I'd have to look that up, but the variation was small as all the testing was done in a row).

@vampire: That's right, yes. The primary goal for this test was to see what the "new" blocks could do on the "typical" modern platform. But I was interested to see what some other blocks could do, blocks that I had on my older testbed last year that used an Athlon 64 CPU (I used a naked single core FX and a capped dual core X2 back then).
