Introduction
ap·o·gee: The farthest or highest point; the apex; a final climactic
stage
The Apogee™ GTZ is Swiftech's new flagship water-block. While it shares the
same name with its predecessors, it also leaps beyond the GT and GTX performance
charts thanks to an entirely new design that pushes and refines both thermal and
mechanical specifications to the limits of today's technology.
Performance Data
Thermal design of the cooling engine combines the benefits of direct coolant
impingement over the CPU area with an entirely new copper base plate design
which is primarily characterized by a
pin matrix composed of 225 µm (0.009") micro structures. This results in a
20% improvement in thermal resistance compared to the Apogee™ GTX.
- Pressure Drop Specification

When the Apogee™ GTZ is integrated in an actual system, the hydraulic
pressure drop remains well within the efficiency range of current
high-pressure pumps such as the MCP350 or MCP655 as illustrated in the graph
below:

Mechanical design of the copper base plate is optimized for Intel® socket LGA
775 and 771. The assembly features a patent pending design characterized by a
topographically mapped CPU contact area which results in a 75% and up to 300%
improvement in TIM joint thermal resistance compared to the Apogee™ GT/GTX
series. Other types of sockets such as AMD® socket F, AM2, and 940 as well as
upcoming sockets similar in design to that of socket 775 may also benefit from
the enhanced contact area.
An enhanced tool free retention system using thumb-nuts paired with a
universal socket 775 motherboard back-plate guarantee high quality, safe and
repeatable mounts.
- Comparative Temperature Data
The following tables report the data collected from testing performed with
actual retail processors under 100% load using CPU Burn. Published results are
the best of a minimum of 5 mounts using the manufacturer supplied retention
mechanism. Flow rate and coolant inlet temperature were maintained at a constant
and arbitrarily chosen 1.5 gpm and 30 °C
respectively. These results are indicative of our test bench settings and of the
tested processors only. Results may vary from one processor to another.
Competitive data is provided for comparative purposes, and is only
representative of the specific waterblock samples tested here. Where different
nozzles were available, best results are provided. Where temperatures only are
given, these are averaged- out core values reported by the processor Digital
Thermal Sensors (DTS).

Motherboard and CPU Compatibility
The Apogee™ GTZ is shipped with an Intel® Core™ 2 (socket 775) compatible
hold-down plate and complies with socket 775 keep-out specification, thus
guaranteeing compatibility with all socket 775 type motherboards.
Two optional hold-down plates provide compatibility with the following
processors:
- Part # MCW60-1U-HD, provides compatibility with
- Intel® Xeon socket 771, and legacy 603, 604
- AMD® socket F, and legacy 754, 939, 940
- Due to the hybrid nature of this hold-down solution, users are
advised to check for possible clearance issues with their particular
motherboards by using the schematic below.


- Part # ApogeeGTX-AM2-HD, provides compatibility with
AMD® Socket AM2, and is fully compliant with the component keep-out
specification.


Fittings & tubing compatibility
The Apogee™ GTZ ships pre-installed with chrome plated high flow 1/4"
BSPP x 1/2" barbs and also includes a pair of 3/8" barb fittings.

Exploded view
- The CNC machined C110 copper base is lapped, passivated (to maintain
a bright finish) and features a 225 µm (0.009") micro pin matrix.

The base plate features a rich mirror finish.

The 225 µm (0.009") micro pin matrix is at the heart of the Apogee™ GTZ
lowest ever thermal resistance.
- The cold plate surface is topographically mapped to provide an
optimized TIM joint with socket 775 & 771 processors. As a result, the
Apogee™ GTZ requires a specific mounting orientation with respect to the
CPU socket in order to optimize performance as illustrated below:
- The housing is CNC machined out of durable Delrin material, and
designed for impingement cooling over the CPU hottest area. The flow
path, as illustrated below shows that the Apogee™ GTZ is port specific:
inlet and outlet cannot be interchanged.
