Swiftech Apogee GTX Extreme Performance CPU Water Block

The Apogee™ GTX water-block is to the Apogee™ GT what Saleen is to the Ford Mustang: a good deal of added performance with some killer looks. The reference to automotive does not stop there: we designed the Apogee™ GTX to provide a racing feel, not dissimilar to that of Edelbrock's famous V8 valve covers.

While the internal structure of both blocks is the same, the longer path between the ports gives the GTX a 1°C advantage over the GT at 100 Watts, making the GTX Swiftech's new performance flagship.

The pressure drop of the "GTX" is ever slightly higher than that of the Apogee™ GT at equal flow rates because of the longer path between the ports, but remains substantially lower than that of a jet impingement type of water-block. In the real world where the range of flow rates is limited by the power of the pump, the "GTX" remains a perfect solution for multi-waterblock loops.

The next graphs show the thermal resistance (C/W) of the two 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.

Internal structure: the CNC machined C110 copper base plate is at the heart of Apogee™ water-block cooling efficiency. Designed using Computational Fluid Dynamics, the Patent Pending Diamond Pin Matrix was further optimized in the "GT" and "GTX" versions resulting in increased surface area and coolant velocity. The base 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.

The housing is CNC machined out of billet aluminum and receives two plating's for a lifetime protection against corrosion: electroless nickel plating (MIL-C-26074E grade B) and Zinc Cobalt plating (ASTM B 840-99 grade 6). A black die is applied after plating strictly for cosmetic appeal. The port threads are 1/4" BSPP standard.
