Introducing the Apogee™ GTZ Ci7. Based on the original Apogee™ GTZ waterblock (Delrin housing), the Ci7 is factory assembled with socket 1366 hold-down plate for out-of-the-box compatibility with Intel® Core™ i7 processors.

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.

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).

The block is awesome, its keeping my I7 3.9 GHz cores around 70c @ 100% loads. Will go higher when thermal paste breaks in and air bubbles bleed out. The backplate on the other hand is really cheap, which is to bad for such a nice block. One of the posts that comes through the motherboard was not properly attached thus the thumbscrew would not tighten in that corner. The post would simply spin and wouldn''t allow tightening. I ended up using my old TRUE 120 backplate.

This is an awesome waterblock. I replaced a Thermaltake with it, and it dropped 20 degrees F right off the bat. I went from the mid 120''s F idle and 200+F Load to mid 100''s Idle to 180F max load. Easy to install though you do have to remove your motherboard the 1st time] and does exactly what it says it will do and that is keep your cpu cool. If your looking for a great block this is it. AND it comes with both 3/8id and 1/2id barbs. Awesome deal
