MCX159-CU series Chipset Heatsinks for AMD® & Intel® platform motherboards Features Introducing the Extreme Duty all-copper MCX159-CU™ chipset heatsink, a whisper-quiet cooling solution designed for motherboards with overclocked front-side bus. The all-copper forged thin-pin design provides nominally better performance than earlier MCX159 designs. The Ultra quiet (18 dBA) VAPO bearing Sunon 40mm fan offers superior MTBF to most stock chipset fans, guaranteeing peace of mind for 5 years or more. This extreme duty heatsink, coupled with Sunon's whisper quiet and high reliability fan make the MCX159-CU an ideal companion to our "V" series heatsinks. This solution is also suggested as an alternative for use with liquid cooling systems in lieu of a chipset waterblock. It provides in effect more than sufficient cooling performance without adding unnecessary restrictions to high-flow cooling systems. This will result in overall lower temperatures at the CPU and VGA level, where it really counts. The MCX159-CU is shipped with hold-down mechanisms for both Intel® and AMD® platforms. See important notes below for compatibility with your motherboard. Example of installation with the Asus A8N-SLI and 2 VGA cards Important notification to users: due to the extreme variety existing among chipset retention mechanisms, as well as location of the chipset relative to the CPU and/or other components, Swiftech simply cannot keep track of all motherboard configurations, and guarantee compatibility. As a result, Swiftech's customer service will respond to specific queries with respect to motherboard compatibility by referring users to this page. It is the responsibility of the user to determine compatibility based on the information posted below. As we receive information from various sources, a "known compatibility" list for system integration purposes is published below and will be updated on an ongoing basis. End-users who will send us a picture of their installed system will receive a $5.00 credit towards their next purchase of a Swiftech product (restrictions apply) Known Compatibility list for system integration CPU socket Motherboard Make Model & link to review 462 Abit NF7-S Rev 2 478 Abit IS7 478 Abit IC7-G MAXII 478 AOpen AX4SG Max 775 Asus P5AD2 series 775 Gigabyte GA-8AENXP-D 462 Asus A7N8X 478 Asus P4C800E 478 Asus P4P800E 754 Asus K8V 939 Asus A8V 939 Asus A8N-SLI Series with 2 VGA cards installed 462 DFI Lan party NFII 462 Epox 8RDA+ 478 Gigabyte GA-8INXP 939 Soltek N4pro back to top Retention mechanisms How to make sure that your MCX159-CU will fit on your motherboard ? The heatsinks ships with two styles of retention mechanisms: 1. To fasten the heatsink via two holes through the motherboard (Mostly AMD® systems, and some Intel compatible Motherboard), use the provided brackets, posts, and springs. Brackets allow adjustments as follows: center to center distance between mounting holes ranges from 2.05" (52.1mm) to 2.41" (61.4mm). click on picture to zoom in and verify dimensions Example of installation with an AMD compatible motherboard 2. If your motherboard uses two or four loops (Always INTEL® systems), then use the provided wire-clips, as shown below. Compatibility: center to center diagonal distance between loops is 3" (77mm).
