The Swiftech Apogee™ GTZ Universal CPU Waterblock 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.

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. The block comes 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 (listed below in options) provide compatibility with the following processors:

1U-S-HD - Apogee™-1U hold-down plate and hardware for Socket 603/604, 771(Intel® Xeon™ - all versions) Socket 754, 939, 940, F (AMD® 64 & Opteron™, including "uncapped" processors).

GTX-AM2-HD - Apogee™GTX Hold down plate and hardware for AMD® Socket AM2

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 schematics shown in the product images.

Block is Port Specific: The Apogee GTZ is port specific, the inlet and outlet cannot be interchanged. Failure orient the flow correctly will result in seriously diminished performance. Please check illustrations in the product images.

Specific Block Orientation: 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 in the product images.

Thermal Design
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.

System flow Rate
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.

Mechanical Design
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.

Retention Mechanism
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 data is 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 Swiftech's 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).

i bought this block cooler with the swiftech dual 120mm radiator and lowered my idle temps to 34*C and full load temps never go above 46*c

This is advertised as a ''universal'' waterblock which may be true, but it is ''designed'' for Intel. The ''mounting'' system which must be ordered for an AMD processor looks and feels like ass. Cheap, clunky and really ugly. The Intel mounting system is perfect..... but AMD as usual gets the shaft..... As mentioned in another review, bit compression fittings do not have enough thread for a good tight fit. In summary, beautiful block for Intel peeps, think twice if you are using AMD

SIMPLY THE BEST I''VE EVER SEEN..TEMPS DROPPED FROM 39c TO BELOW 20c AND AFTER AN HOUR OF PRIME95 ONLY GOT TO 34c WITH AN I7-920..THANKS FrozenCPU

This performs outstanding, but Bitspower compression fittings do not have enough threads to seal very well with this block.

This block is simply awesome, all said. Pros -Beautiful looking! Chrome finish is very nice -Mounting System is the most innovative and effective I have ever seen. Guarantees excellent mount to MoBo -Performance!!! Using this block in tandem with a tri-120mm DD radiator and in line with two VGA blocks, I found that even during extremely intensive gaming, the CPU never goes above 35* C. -Accessories- Comes with both 3/8 and 1/2 barbs, saving you a good $10 Cons -NONE All in all, this is simply THE best block on the market right now
