The FuZion v.2.0 may not be a monumental difference from its older brother, but this prettier version has a lot going for it. Outside of the convenient Pro-Mount for LGA-775 users who want to set it and forget it, it's got a lot of fluid running through its veins.

The differences in this test may seem small, but we're dealing with a battle of some of the best of the best. The TDX, as I've said time and again, is far from too old to compete. But the FuZion manages to shave degree after degree off as my beefy test system starts to stretch its legs. It's to the point where I look at the radiator and wonder if it's becoming the limiting reagent of the system...

All of this is before you even begin looking into "options" like the same pressure nozzles you can slap onto the TDX. Restriction will be cut down to...what, the second best block in watercooling? If it's the only block in your loop, you might as well -- it's just going to bring temps down further. The whole idea of the FuZion 2.0 is attractive at this rate, and its price doesn't hurt either. At only ten quid at max over competing blocks, it's hard not to love it.

Whether you like the Delryn and chrome look or it's really not your thing, there's one thing that is undeniable. The D-Tek FuZion v.2.0 may be little more than a form revision, but that's because its function still sits as king of the high-flow world. If low temps and lower restriction are your thing, you won't go wrong choosing this block.
