D-Tek Fuzion



D-Tek Customs has been manufacturing high performance water blocks since 2001. The Fuzion represents an amalgamation of several design concepts, including direct impingement, extruded pin and what I've come to define as a multi-chamber water-block which utilizes pressure and flow in it's design. That statement might seem prima facie after all don't all blocks take these factors into account? Yes but not to the degree multi-stage blocks depend on a mid-section which places multiple return ports above the pins to affect heat-transfer. D-Tek is also unique as it utilizes a base plate which encapsulates the medium (H20). At 35.5mm x 35.5mm the Fuzion sports one of the smallest "internal footprints" (55.24mm x 55.24mm external) yet it's copper base has more material then most (except TDX) typical "flat plate" designs. Below we see the block with mounting plate removed.



D-Tek supplies all the required accouterments and requires just two mounting plates to support just about every type of Socket. D-Tek also included some of the highest quality mounting hardware.





D-Tek Fuzion Specifications / Features:

Full Copper 110 base plate featuring over 340 dense Rounded Micro Pins and 1.4 sq." pin spread optimized for large die Dual and Quad core processors.

Airfoils are used to optimally direct water flow throughout the block.

Anti-oxidant treated precision machine lapped copper base plate.

Black Derlin Top with brass threaded inserts embedded for durability and lightweight construction.

Black Derlin Mid Chamber is pressure balanced and internally optimized for rapid water transfer and perfect for multiple block loops.

Pre-Installed Chrome Plated 1/2" or 3/8" Hi-Flow Hose barbs included.

Includes all hardware and Chrome Plated S/S 304 Socket Mounting Plates in Intel® and AMD versions that are compatible with most modern motherboards featuring mounting holes around the socket area.

100% leak tested prior to distribution.

Backed by a limited lifetime warranty on parts and labor.

D-Tek Fuzion is supplied mounting hardware supporting the following :

AMD AM2 via 4-holes through the motherboard.

Socket 754/939/940 (all AMD Athlon™ 64 series) via the 2-holes screwing into the socket back-plate method.

Socket 462 (AMD Socket A) via the 4-holes through the motherboard method.
Important Note: AMD 462 Socket lug mounting is not supported.

Intel® Processors - Socket 478 (Intel® Northwood P4/EE) via the 4-holes through motherboard.

Socket 775 (Intel® Socket T Prescott-style LGA) via the 4-holes through the motherboard.

Socket 423 (Intel® Willamette P4) via the 4-holes through the motherboard.

Socket 771/603/604 (Intel® Xeon™ all versions) via the 4-holes through the motherboard.

The Fuzion deviates from the typical 3mm thick flat copper base-plate due to its "side-walls" which, as stated above encapsulate and contain the water surrounding the base and level with the pins. Simply put this places more copper mass (surface area) around the water as it removes heat. This may seem trite until you consider it’s the copper medium and its thermodynamic properties transferring most of the energy from the IHS below to the fluid. The pins radial pattern spread to each corner where channels force the water into small orifices just below each return port.





In this respect water blocks such as the Fuzion (and EnzoTech Sapphire) are what may be described as multi-stage water-blocks. Water enters the block passing through a center port in the mid-section or chamber, impinges on the extruded pin's center mass and then follows a centrifugal flow as a result of equi-distant return ports which feed into the mid chamber above. D-Tek employs four (eight in EnZotech Sapphire) return ports above each corner of the base plate. D-Tek engineers were most astute in making available "nozzles" (in red) which constrict the flow increasing impingement pressure and one which splits the flow for multi-core applications.

D-Tek Fuzion Accelerator Nozzle kit, Detailed Description:
The FuZion Accelerator Nozzle kit is a performance enhancement to the already top of the class performance of the FuZion CPU Block. The kit includes various sizes to tailor the FuZion performance to your particular setup whether it is single or multiple block loops.
Kit Includes:

1 x 3.5mm Nozzle

1 x 4.5mm Nozzle

1 x 5.5mm Nozzle

1 x 6.5mm Nozzle

1 x Quad Split Nozzle

1 x Intake Seal

1 x 2.5mm Allen Wrench
Kit Features:
Durable precision molds and precise fitment
Optimized design reduces pressure drop to minimum



D-tek sells an Accelerator Nozzle kit (similar in principle to Danger Den) which gives the end-user a wide range of tune-ability and pressures to experiment with. For this round-up I chose the "Quad Split Nozzle" which must be oriented correctly to work. In fact improper placement could ultimately lead to a decrease in performance. The photo below shows the base plate and mid-chamber. The mid-chamber is situated as it would sit atop the base-plate. Note the diagram on the instruction sheet.



Finally D-Tek's Fuzion didn't have a mirror finished base plate, similar to Switech's GTX. The emphasis was on a perfectly flat (insofar as that can be achieved and measured) surface rather then a polished surface.
