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 Kentfield 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 HERE.
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.

The Apogee GT averages 0.01 °C/W better than the Apogee on single-die processors.

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 provided HERE.
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 the COMPATIBILITY LIST
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.
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 plate.
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™).

I changed the block from the stock one on my Kandalf LCS and my temps dropped by about 8°C. Needless to say I am very satisfied, except I much prefer higher quality compression fittings, overall they improve my confidence in my wc setup.
I bought this as my first cpu waterblock, and I've been using it in conjunction with the Swiftech chipset cooler. Its a very good combination, and so far, I can't seem to find anything wrong with either of them. Great product, would buy again.
Looks great, preforms quite well - keeps my e3110 oc'd about 46 degrees loaded, easy to install and lots of extras included in the box. Doesn't perform quite as well as some of the more expensive blocks, but it definetely does the job.
I bought this with my loop to cool my overclocked E6300 and it works great with the rest of my loop (HW Labs BIX240 > D5 Vario > T-Line > Apogee GT > back to BIX240). The shiny retention plate or whatever looks real nice in my case.It's a great price too and it can be "bowed" for that extra little bit of performance. Not as good as some other blocks but then again much cheaper.
I have this waterblock since the last 2 months and I can't ask for a better one. It keeps my 6000+ OC to 3.51GHz under 40 degrees full load even with 2 water cooled graphic cards! It's not expensive and very nice looking. It comes with many sets of different barbs. 5 stars!
