Swiftech APD2-NP-AMD4 Apogee Drive II for AMD All Desktop Sockets (No Pump)

Product Description

Improved Thermal Performance	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 II yielded up to 1.2ºC better thermal performance than the Apogee™ HD (Intel i7 2600K socket 1155) - When installed in a system by itself, including only a radiator and a reservoir, the Apogee™ Drive II edged the HD by 0.2ºC (Intel i7 2600K socket 1155).
NO Flow Restriction	With the top 5 water-blocks in the world being within a couple of degrees from each other, the next differentiating factor to many enthusiast users is flow restriction. Given that the 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!
Twice the Reliability	Even if we consider that adding a second pump to a liquid cooling system yields relatively marginal thermal improvements, the redundancy offered by a second pump is a priceless safety feature that can save your expensive components from fatal overheat in case of a pump failure.
Speed-adjustable	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 in a 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-down depending on CPU load. 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.
Compact form factor	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 bit easier by consolidating 2 best-in-class performing devices into one.
Fine-tuned Retention Mechanism, with universal Desktop Processor Compatibility	Swiftech's retention mechanism is widely recognized as the simplest and safest to use. It has been further enhanced with added attention to details and quality, such as hollowed thumb screws, and improved back-plate fabrication. In order to avoid waste, and reduce cost, the Apogee™ Drive II is available in 3 separate versions compatible with the following socket form factors: Version 1155/1366: for Intel® processors using Socket LGA 775, 1155/56 and 1366: back-plates for 1155 and 1366 are included and socket 1155 back-plate is installed by default; the back-plate for socket 775 is not included and mailed to users free-of-charge. Version 2011: for Intel® processors using Socket LGA 2011 Version AMD: for AMD® processors using Sockets 754, 939, 940, AM2, AM3, 770, F, FM1 and the latest AM4 (Ryzen processors) Separate kits are also available for the above 3 groups of sockets for upgrade purposes.
Shipped with High Performance Thermal Compound	The Apogee™ HD ships with Swiftech's TIM-Mate™ thermal compound highly rated for its excellent thermal performance and ease of application.
