Swiftech MCX462+ Heatsink Review

The Heatsink



When you pick up this sink, the first thing that enters your mind is "WOW!" I have tested quite a few coolers, but none of them have the weight that this monster carries in its bulky build. Even the Alpha PAL8045 series cooler only weighs in at 520 grams. This behemoth tips the scales at a hefty 650 grams, and remember, this doesn't include a fan of any kind. For those who are metrically challenged, this is just a tad under one and a half pounds. We're talking about a massive cooler here but since mass generally equates to more effective cooling we should be in business.


Also of note is the fact that Swiftech doesn't use a fin technology of any kind. Instead, they have elected to use a total of 371 pins that have been press-fitted to the base to create a staggering amount of surface area. But to make sure that surface area is maximized, check this out:



Every single one of the pins have been textured with a helical design to further increase the area available to dissipate heat. The picture is becoming clearer about why folks like this cooler. But we're not finished yet!


The Base



**Insert favorite expletive here**


Whew! Now that I have that out of my system we can sit back and enjoy what equates to nothing less than an outstanding piece of workmanship. The base of the MCX462+ heatsink is as close to perfect as I have yet seen in a retail cooling solution. Not only is the surface flat with no blemishes, it has also been lapped to a mirror finish. If you have plans on lapping your own sink in the future, then look at this as an example of what you should aim for. The base is simply beautiful.


Oh, and for those who wonder why this heatsink weighs so much can take a good look at the thickness of the base above. We're talking a full 10mm not including the protrusion that sits over the processor core. Folks, we're talking a full 1/2" of copper here!


The Fan


Whoops, did I forget to add a picture here? Nope.


The Swiftech coolers don't come with fans, just the heatsink itself. And while this may seem a cheap way out, it gives the end user (that's us) a lot of flexibility when it comes to just what to use.


The sink tested today will allow you to use any standard 70mm or 80mm fan. While there aren't that many 70mm models to choose from, there is a nearly inexhaustible supply of 80mm models to choose from. Whether you are looking for a nice quiet fan or something that tries to lift the entire system off the ground, you can go for the gusto here.



Though the fan is not included in this package, there is the means to attach your fan of choice. The plastic pushpins will work for securing an 80mm fan to the sink. If you happen to choose a 70mm fan, then you just remove the four arms from the corners and use the included screws to mount the fan directly to the base.


One final item of note is a recommendation by the manufacturer. They suggest a fan of no less than 45-CFM airflow rating if you are using this cooler on an overclocked system. Just some food for thought as you begin your search for the perfect fan for this monster.
