Swiftech launches MCX603-V heatsink for Xeons

Swiftech released the MCX603-V lownoise heatsink for Pentium 4 Xeon systems. According to Swiftech the MCX603-V is of equal size and pin design to the MCX462-V, thus features identical performance and usage specifications. This heatsink is designed to work with 80mm fans only mainly because there is not enough space between the heatsink and the Xeon processor, and the heatsink compatible with all socket 603 or socket 604 Intel Xeon motherboards.

This heatsink has a copper base with aluminum Helicoid pins for optimal heat dissipation. The spacing and angles between the concentric rows has been precisely calculated to optimize cooling and reduce noise at air flow levels as low as 22 CFM and 23 dbA. There are two ways to install this heatsink :

Plug-and-play installation with Intel's validated retention mechanisms for OEM processors (does not necessitate removal of the motherboard for installation).

Optional screw/spring assembly retention system (requires removal of the motherboard for installation).

Heatsink specifications

CNC machined, C110 copper base, 3"W x 3.3"L x .500"H, flatness better than 0.0003", micro surface finish 8 or better.

374 Helicoid Pins made of High Thermal Conductivity Aluminum Alloy, press fitted in the base.

Heatsink base dimensions 3"x3.3"x1.66"

Heatsink top dimension 3 3/4" x 3 1/2"

Weight: 22 oz (620g)

A smooth mirror finished base is very important for Swiftech, the heatsink base is lapped to 0.0003" (3/10 of 1/1000"), and polished to near-mirror finish to promote optimum thermal conductivity :


The suggested retail price is $49.95, without a fan.
