Swiftech MCXC370 Copper Heatsink Review
It's about time that Swiftech started choosing shorter and more friendlier names for their heatsinks. Maybe the next cooler could be called the Swiftanium 4TM, or perhaps the Swiftech XPTM. It's just a thought. [Hint, Hint]
The Swiftech MCXC370 is meant to be a mid-level cooler for the thongs of consumers who don't need something quite as large as the MCX462. In any case, this is an all new heatsink and one you'll definitively want to read about before getting. The only differences between the MCX370-0A and the MCXC370 have to do with the copper base. The first version of this heatsink was all aluminum, and this one has taken advantage of the copper base for a little extra 'oomph.'
Textured pin heatsink:
Textured pins have emerged as one of the two main calling cards of Swiftech coolers. The first being those nice base finishes. I got a big response last time by saying the bases "weren't polished", here is a line by line explanation right from the man, about how they're actually finished.
Well there you have it, I stand corrected, Swiftech heatsink bases are polished - just not to a mirror shine. ;-)
What about Dust?
There is a little voice in the back of my head that is kind of wondering what's going to happen with all those threaded pins over time. I mean sure, they do increase surface area and turbulence, and hence performance, but what happens when dust starts settling down? I've seen some pretty nasty heatsinks after as little as two months of use that were caked with dust, and all their surfaces were smooth. Somehow I'm wondering just how big of a dust trap the textured pins will be over time. Dust as we all know, will impact on the performance of any heatsink if enough of it builds up. With all those little nooks (per pin), here's hoping that the textured pin technology doesn't act like a super dust filter.
Swiftech has improved the width of the retention mechanism from the previous version but I am still a little curious about how well the force is being directed downward. Since the clips are centered on the heatsink, the force the heatsink exerts is also centered. Ideally, the force being exerted by the heatsink should be off-center, and over the location of the processor core.
The bottom line is that the MCXC370 takes a bit of extra time to set properly, else it may look like it is mounted properly (and it will work just fine), but you may be missing out on several degrees of extra cooling as the heatsinks' forces are concentrated on one edge of the die. A good analogy would be shifting the weight of your body to one foot while standing. Both of your feet are still touching the ground, but one foot is taking more of your bodies weight.
These issues (while not in any way life threatening) cropped up on our test system, where we could adjust the spring tensioning to produce the best thermal interface insofar as forces over the core were concerned.
