Some things in general....

A couple of months ago I tested some Athlon 64 heatsinks over here. Some big names like Thermalright were mentioned, but at least one player was missing: Swiftech!

We received the MCX6400-V™ heatsink and we put it to the test right away. But before we start, let me go to the fridge and to get some ice cubes to put in my coke. Belgium is a strange country, last week we were almost drowning in rain, today the sun is shining and it is 27°C outside. Nice weather. But not when you have several computers running in your room. That's why you'll see some high temperatures in the tests.

Enough chit-chat, time to present you today’s contestants:

MCX6400-V™ vs. SLK948-U vs. Ajigo MF043-044A (boxed cooler).

Both the SLK948-U as the Ajigo MF043-044A were presented in this [M]ad review, so they don't need an introduction . Our newcomer however hasn't been introduced to our readers yet, se here we go:

  • CNC machined, C110 copper base, flatness better than 0.0003", micro surface finish 8 or better.
  • 405 Helicoid Pins made of High Thermal Conductivity Aluminium Alloy, press fitted in the base.
  • Weight: 26.4 oz (750 g)

    More info can be found here...

    As in most of my articles, I tend to mention the content from the package. This time I found:

  • Heat sink
  • Two spring loaded screw assemblies
  • Two nylon spacers
  • Four 80 mm fan straight brackets
  • Four snap-rivets (for fan installation)
  • Thermal grease - Arctic Alumina

    The brackets for 92 mm fans are not included by default but can be included as an extra option. Swiftech’s in-house testing results concluded that this heatsink performs better with 80mm fans anyway!

    The MCX6400-V™ is compatible with 80 and 92mm fans. However, comparative test data shows that 80mm fans perform in general better with this heatsink, and at lower noise levels. Nonetheless, 92mm fan brackets are also available as an option. The MCX6400-V™ ships without a fan in order to allow users to customize the product to their application.

    Let's take a look at the heatsink itself. The base finishing is simply perfect-a-mundo. Really, this sink has a mirror finish, it is also is a little bit bigger compared to his Socket A brother the MCX462-V (reviewed here).
