D-Tek Fuzion GPU and Uni-Sink

The GFX block arrived in a white box, the Uni-Sink in a plastic bag.


First, I unpacked the Uni-Sink. The product has a well-manufactured, sturdy feel to it with no sharp edges. The portion above the voltage regulators is beefed up to handle the heat, but the part above the memory and NVIO chip is rather plain. On the bottom side, you can see some thermal transfer tape. What did disappoint me is that there are no instructions with the Uni-Sink. Even though its installation is straightforward, it would be nice if D-Tek told you which way you should tighten the screws, as well as if you should apply some thermal paste between the chips and the thermal pads.


The GFX block is well packed in bubble wrap, you get two backplates and top plates (one for 8800 series, another for 7xxx cards and before, as well as Radeon X1800 series cards). However, there is no mounting hardware available for X800 series cards, but that shouldn’t be a big issue, since virtually no power user uses those cards nowadays. The instructions are clear and straightforward.

D-Tek also provides a thermal pad they advise you to use on the 8800 cards to gain more contact area, since the area around the standard contact patch (say X1800 cards) is recessed. I did not use this pad however, as it actually worsens contact because it is too thick, which leads to higher temperatures.

In the package, you will additionally find two High-flow ½” barbs.


The only thing I would be scared of with the construction of the GPU block is the very thin plexi top, which could be prone to cracking.


The base of the water block is very well polished, yet not quite as good as that of Swiftech, for example.
