ap·o·gee: The farthest or highest point; the apex; a final climactic stage
Following in the footsteps of the award winning Apogee CPU water-block, the
APOGEE GT model takes the cooling performance to yet another level.
The GT's primary difference with the Apogee is an optimized internal structure.
The improvement in thermal performance scales from a minimum of 1°C and up to
3°C (at 100W) depending on the CPU's, with Intel's latest Kentsfield quad core
processors benefiting the most from the revised structure.
During the course of our test and validation procedures, we also uncovered
additional means to further improve overall thermal performance as described in
the tweaking guide below.
The Apogee GT was tested in our labs, using our standard equipment
and testing methodology and
is compared to the Apogee and -for reference the Storm water-blocks below. Test
equipment and methodology closely follow Intel®
Actual CPU testing was also conducted, and the data is reported below.
It can be seen that the pressure drop of the "GT" is only slightly higher than
that of the Apogee at equal flow rates, but remains substantially lower than
that of a jet impingement type of water-block such as the Storm. In the real
world where the range of flow rates is limited by the power of the pump, the "GT"
remains perfectly adapted to multi-waterblock loops.
The next graphs show the thermal resistance (C/W) of the three water-blocks at
various flow rates. Data sets are separated into single-die and dual-die
processors in order to better reflect product performance depending on the
current market offerings.

In dual-die processors, the performance gap between Apogee and Apogee GT
increases to an average 0.03°C/W in favor of the "GT".
"Live" CPU Testing
In order to further validate our data and provide users with points of
reference, we also tested the Apogee GT water-block with popular CPU platforms HERE.
During the course of our live CPU testing, we have uncovered the fact that the
overall performance of the water-block can greatly benefit (by up to 0.03°C/W)
by artificially inducing a bow -or a convex shape, in the water-block base
plate. Further explanations and test results are providedHERE.
Motherboard and CPU Compatibility
The Apogee is essentially meant as a universal water-block. It ships with all
the necessary hardware for the following processors which are classified below
by the type of sockets that they use:
- Socket 478 (Intel® Pentium® 4),
- Socket 775 (Pentium® 4, Core Duo, Core 2 Duo ),
- Socket 603/604 (Intel® Xeon™ - 400 and 533 FSB) - see
- Socket 771 (Intel® Xeon™) - Optional AP-NC604 hardware
pack is required.
- Socket 462 (AMD® Athlon®, Duron®, MP, XP) - see notes 2
and 3 below
- Socket 754, 939, 940 (AMD® 64 bit processors)
- Socket AM2 (AMD® 64 bit processors) - All known
motherboards but one (*) are compatible at the time of release. Please check
- Socket F (AMD®) compatibility is undergoing validation
and will be updated as soon as possible.
Removal of the motherboard is necessary to install the mounting posts in all
cases, except with
AMD® Athlon™ 64, Opteron™ (socket 754, 939 and 940), and socket AM2.
The Apogee GT includes a separate
hold-down plate for AMD processors using the AM2 socket (installation required)
Fittings & tubing compatibility
Three sets of Nylon hose barbs are included with the device: 1/4" (6mm), 3/8"
(10mm) and 1/2" (12mm).
The apogee uses NPSM threads. Please refer to "Connector Thread Compatibility" HERE for
further information about this US standard.
Note 1: Intel® Xeon™ "Nocona" processors (800Mhz FSB motherboards)
mounting hardware is sold separately under part # AP-NC604
Note 2: AMD® socket 462 (socket A). The Apogee can be used exclusively
with motherboards featuring the 4 mounting holes around the socket.
Note 3: Socket 462
compatibility (tall capacitors)
An optional hold-down plate raising kit is available for socket 462 motherboards
featuring tall capacitors in the neighborhood of the socket. This kit raises the
hold-down plate and allows up to 0.900" clearance (measured from motherboard to
hold-down plate. The part # is AP-S462-R. This kit is available free of charge
to users for all Apogee water-blocks purchased prior to 2-20-06. Qualifying
users in the US are directed to call Swiftech customer service to procure the
kit. Qualifying users outside of the US, please contact your Swiftech
distributor in the area.
Raising kit - Part # AP-S462-R
- Internal structure: the CNC machined C110 copper base plate is at the
heart of Apogee GT cooling efficiency. Designed using Computational Fluid
Dynamics, the Patent Pending Diamond Pin Matrix was further optimized in the
"GT" version resulting in increased surface area and coolant velocity. The
thickness remains at 3mm to promote a high compliance factor with its mating
surface (i.e. the CPU heat spreader) thanks to the base plate flexing
ability. This particular feature allows additional "tweaks" to the Apogee
generation of water-blocks and may yield substantial performance gains as
described in the tweaking guide HERE.

- The housing is injection molded out of Black Acetal. This process is key
to allow mass production of the water-block, and thus economies of scale.
The "GT" housing is not compatible with the regular Apogee as the deck
height has been adjusted to match the new pin height featured by the GT base
Patent Pending Housing
- The universal hold-down plate features mounting holes for all current
Desktop and midrange server processors (Xeon™, Opteron™). Optional hardware
is available for high-end server processors (Itanium™).
