Well, it was actually an XP-90C and a screaming Tornado vs (what appears to be) a 6000 (3/8" tubing) a single radiator and who knows what fan and there's no mention of the pump. The current H20-120 kit on Swiftech's site is different than the one they tested so I have no idea of what components they're actually using for the test--but it isn't "high-end" water or even mid-range water. And, when a reviewer doesn't specify the components being tested.... I'll let you judge the validity of the "test."
