D-Tek FuZion v2.0 Waterblock

We have a winner

The D-Tek FuZion v2.0 may not be a large step forward from its predecessor mechanically, but it does have some power under the hood. As you may have noticed in my testing methodology, I wanted to make sure to test the block's previous strong suit – multi-block layouts.

I was in no way disappointed.

As you can see by the results below, both the Danger Den TDX and the D-Tek FuZion v.2.0 perform admirably in a single block series. To be honest, I have to once again commend Danger Den's craftsmanship in this regard – for a block that was designed over four years ago (I am one of the old holdouts who just wasn't willing to move to the multi-core block yet), temperatures are kept cool and breezy and right in line with the much beefier-designed D-Tek FuZion 2.0.

And that's where it ends. See, for as good as the TDX can keep a multi-core CPU cool on its own, it needs a good pressure nozzle to do it. This adds further restriction, lower flow, and thus a bit less heat exchange. Now, on one block, that's not going to be seen all that well...which is why I made sure to add a GPU block into the mix as well.

By putting another block in the loop, restriction was substantially increased. Exactly where that block lands matters very little – systems reach a state of equilibrium quickly, so heat and pressure are largely maintained as constant except for right at the entrance and exit of specific sub-systems (i.e., blocks, radiator, etc.).


The addition of the Danger Den 8800GTX block cuts the flow of a loop considerably, while at the same time dumping in plenty of extra heat. At idle temperatures, there was already another degree of difference between the TDX and the FuZion 2.0. Since this figure is an additional degree of difference not shown in the single-block setup, it's safe to assume that this is due to the increased flow provided by the FuZion 2.0.

At load, the lead only broadens – the FuZion 2.0 stayed at least three degrees cooler than the TDX on average, which means a big difference when flirting around that dangerous 50-degree mark.

Conclusion

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 new FuZion. 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.
