Up Close

The Alpenfohn Matterhorn comes in a predominantly black glossy box, which actually has a window in the side of it to show you that this is the Black version of the cooler.  Inside you get the usual fixings as well as  some LNAs and a set of four spring clips.

Although it has Copper heat pipes and Aluminium fins, the entire surface of the Matterhorn is finished in a rather nice almost matte, satin Black.  The included fan is a 120mm, 1500 rpm  version of the WingBoost2, and we have to say with its rubberised coating and white cowling interior it looks and feels like the highest quality fan we've seen in this whole test

At just 100mm deep with the fan attached it's not going to cause any RAM issues, and with a height of just 158 it'll fit into most mid tower cases

The top of the Matterhorn is finished in the same matte/satin Black as the rest of the cooler, with the top plate being formed so as to mask the ends of the heat pipes.  Although the spring clips used are subtle and can be hidden under the top cover, we do feel the bare metal nature of them detracts from the overall aesthetic.

The instructions for the Matterhorn open up into a sheet so large you could have a picnic on it and caused me to have a flashback moment to when I used to make model aircraft kits as a lad.  They also had a fairly significant error on them, identifying the Intel mounting bracket as the AMD one, and vice-versa.  In all other respects, the Matterhorn was reasonably simple to fit, although when tightened down to its max we didn't think it was seated particularly well on the CPU lid.  Sadly our suspicions of poor performance related to poor CPU pressure were to come to fruition as the Matterhorn failed to impress.  OK, so it came half way up it's class ranking, and half way overall, but we think had the fitting method provided a tighter clamp it could have done much better.

Had a quick look..
dont see any AIO's in there as a comparison.. I think it would have been nice to see atleast 1-2 of the most popular ones in there, it would just round out the comparisons a bit better imo if you also factor noise efficiency and redundancy.Quote

Great article, good to see my D15 is still a beast in the air cooled department.

One small thing, while reading the D15 page I couldn't help but notice something wrong.

With the front fan installed you are though limited to standard height RAM.
This is actually not the case, the fan can be positioned forward due to the design of the mounting which allows for big RAM if you have the case clearance for the fan to protrude off the cooler.Quote

That explains all the hype around the Cryorig lot, good prices and performance there. Great to see so many all together in one place for comparison.Quote

The BeQuiet coolers are meant to be tightened from the back of the motherboard, not above and between the fins. No wonder you found it hard to do.. If you are saying that poor fitting is the reason they don't perform well, then the test results are not representative of the coolers performance.Quote

I bought the Be Quiet Dark Rock TF for the looks for the Lian Li Q10 build - was supriced that it placed so low.

Have the Raijintek Pallas on my living room rig cooling a G3258 and I thought it was great.Quote
