Swiftech MCX462 heatsink review

Price: $68


I have been wanting to test out a Swiftech MC462 heatsink for some time now.. but they have since came out with the new model, MCX 462. I have never used a Swiftech heatsink before, but I really like the appearance of this one. Swiftech has been known for producing high quality heatsinks that out perform any other. They have some of the biggest heatsink on the market, and some of the biggest prices as well. The size of the MCX 462 will make you mouth drop open, and the weight of it make it feel like your holding a brick. We all know it's very impressive, but does it cool?

    What's in the box?

  • I was kind of discouraged by the box that the heatsink came in. It was a very plain white box with the name on it and a picture of the heatsink in black. No colors or anything on the box. Why? I'm not really sure.. Maybe Swiftech heatsinks are sold only online, and don't require a pretty retail box. That would be my guess. However, once I opened the box up, I found that it was packaged very well. The heatsink and fan was surrounded by styrofoam.

  • I found the following in the box:

  • (2) Bags of screws and mounting hardware
  • A nice two page Installation guide
  • The heatsink and the big fan

    In-depth look

  • Here it is, the big MCX462 heatsink. If you have seen the ThermalTake Volcano 7 heatsink then you could compare the size of this heatsink with it. They have a 4 pin molex connector on the fan. I think this is a good idea, because if they used the smaller 3 pin motherboard connector people would more than likely plug it right into the motherboard. You don't ever want to plug a high powered fan in to your motherboard, as it could fry your fan or your motherboard. Swiftech has prevented this problem and just installed a 4 pin molex connector, to insure you don't plug it into your motherboard. There is also another wire coming from the fan, this one is a 3 pin motherboard connector, which only has one wire going to the 3 pin connector. This one, you should plug in to your motherboard. This allows you to monitor the RPM of the fan from within your bios, or within windows.

    Check out the bottom of this heatsink; the surface is super flat! The Swiftech web site states: "flatness better than 0.001". Now that, is flat! The surface contains zero imperfections!

    Kind of different looking than other heatsink that you have seen, huh? This is the Swiftech trademark on their heatsinks. There are a total of 371 pins in all, the size of .093" The older MC462 heatsink only had 261 pins but they where bigger in size, .125" to be exact. The new heatsink is suppose to transfer heat better than the older one did.

    The fan of the MCX462 heatsink, is very large. It is a Delta 80mm fan, that has a rated speed of 4900rpm. You can't have a delta fan without the noise though! The noise level of this Delta fan is 48.5dbA. Loud? Yes, some people would consider it loud. However, I had a ThermoEngine V6 heatsink, with a 7000rpm Delta fan, and that thing had a high pitch sound to it when it ran. This Delta fan does not have that same sound. I find this Delta fan quiet compared to my old one :)
