ST-APD2-NP-AMD | Swiftech Apogee Drive II CPU Waterblock - For AMD Socket 754

Part Number: APD2-NP-AMD

 

 

Like a phoenix rising from its ashes, the Apogee™ Drive II integrated pump & waterblock returns to take its place at the helm of Swiftech's CPU waterblock product line. Close to 24 months in the making, it includes all the latest technological advancements that we have to offer:

 

 

World's best thermal performance based on our comparative testing, when added to a conventional liquid cooling system including pump, radiator, and reservoir, the Apogee Drive IIyielded up to1.2C better thermal performance than the ApogeeHD(Intel i7 2600K socket 1155) -When installedin asystem by itself, including only a radiator and a reservoir, the Apogee Drive II edged the HD by 0.2C (Intel i7 2600K socket 1155).

 

With the top 5water-blocksin the worldbeing within a couple of degrees from each other, the next differentiating factor to many enthusiast users is flow restriction.Given thatthe Apogee Drive II has an integrated pump - one that features the highest flow rate in the useable range, it doesn't restrict flow at all -on the contrary, it enhances it!

 

Even if we consider that adding a second pump to a liquid cooling system yields relatively marginal thermal improvements, the redundancy offered bya second pump is a priceless safety feature that can save your expensive components from fatal overheat in case of a pump failure.

 

Thanks to the PWM function of the integrated MCP35X pump, the Apogee Drive II pump speed - and operating noise, can be adjusted from 1300 RPM all the way to 4500 RPM. When two pumps are running in tandem ina liquid cooling system, it is not necessary that their speed be identical. So your Apogee Drive can either be pushing massive flow at 4500 RPM, or simply humming along in the background at a completely silent 1300 RPMs. Either way, it will never slow down your flow, but always increase it. 

Another great benefit of the BIOS controlled PWM is that the pump speed can be tied to the CPU temperature and increase or slow-downdepending on CPUload. The pump could be running at minimum speed when the processor is at iddle, and speed-up when the CPU temperature reaches a set temperature.

 

Have you ever tried to fit a conventional liquid cooling system in a small form factor computer? The Apogee Drive II makes this challenge a great biteasier by consolidating 2 best-in-class performing devices into one.

 

Swiftech's retention mechanism iswidely recognized as the simplest and safest to use. It has been further enhanced with added attention to details and quality, such ashollowed thumb screws, and improved back-plate fabrication.

 

 

In order to avoid waste, and reduce cost, the Apogee Drive IIis available in 3 separate versions compatible with the following socket form factors:

 

 

The Apogee HD ships withSwiftech's TIM-Matethermal compound highly rated foritsexcellent thermal performance and ease of application.

 

When considering the cost of purchasing an MCP35X pump ($99.95)+ an Apogee HD ($74.95), the total cost at MSRPis $175; compare this to the $140 MSRP of the Apogee Drive II(average of three models), this is a $35 or 20% saving.

 

 

The following graphs reports the data 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. These results are indicative of our test bench settings and of the tested processors only. Results may vary from one processor to another.

The following two charts compare thermal performance while the Apogee Drive II is added to an existing loop, for a total of two pumps in operations:

 

 

 

The following chart compares thermal performance of a conventional setup versus one where both water-block and pump have been replaced by an Apogee™ Drive II (1 pump in operations):

 

 

Note: "Temperature Delta" means the difference between the average CPU core temperature and the average air temperature.  This reporting method reflects the true efficiency of the cooling system because it eliminates ambient air temperature variations in the data being compared. Users are cautioned that the above data is provided for reference only, and is not directly comparable with CPU temperature values collected a) from an enclosed chassis and b) without deducting ambient air data.
