The Swiftech MCX-4000 is an awesome socket 478 heatsink, and has always been one of our favorites around here at the office since I wrote my review in the end of ’02. That’s not to say that the 4000 is completely without flaws. Its mounting system, while very solid, is not exactly an easy task for the novice computer enthusiast. Also, the 4000 was not really designed with 92mm fans in mind, and its mammoth size doesn’t fit in between the rows of caps on some motherboards. The MCX-478V attempts to correct these issues, and improve performance with quiet fans. Today I'm going to put one to the test against the current quiet champion Zalman CNPS7000Cu.
One glance, and you can immediately tell who made the MCX-478V. The Swiftech theology is if it ain’t broke, don’t fix it. The aluminum alloy helicoid pins affixed to a 1\2” copper slab has been with them for quite a long time, and it was certainly no surprise to see it utilized once again on the 478V. The major difference between the MCX-478V (as well as its AthlonXP MCX-462V and socket 754\940 MCX-6400V cousins) and square Swiftech designs of yore is the “V” shape, which allows for fans up to 92mm to cover the entire surface area of the pins, while allowing the copper base to be small enough to fit inside the standard Intel socket.
Here are the technical specs:
• 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)
