If "thicker" (in airflow direction) heatsink isn't offset its fan can block some DIMM slots or at least demand low profile DIMMs.Ok thanks,
The Matterhorn looks quite a bit bigger than the NH-U12S, would it block anything like the NH-U14s would?
That's why Noctua made NH-U12S such "skinny" (with densely spaced fins to keep surface area) compared to its predecessor NH-U12P:
Integration of memory controller to CPU mandated DIMM slots to be always near it.
Thermalright uses offset in Macho 120 to allow big loosely spaced fins for low airflow resistance and efficient heat dissipation down to lowest fan speeds:

Should be one of the better performing 120mm fan heatsinks for low noise cooling.
Thermalright is one of the older CPU heatsink makers from time before heatsinks because fashion thing and has lots of experience.
And sure comes at good price.
Unlike Noctua making you pay lots for their acoustically mediocre fans.
Matterhorn's six heatpipes is overshooting for heatsink's size/surface area.Alpenfohn Matterhorn Pure is a great cooler for £33.95. It is 138x123x158mm with 6x 6mm heatpipes. H7 is 123x145x98mm with 3x 6mm heatpipes.
While on other side Cryorig's three heatpipes is toward other end and might degrade its performance at very high heat loads compared to heatsinks with more heatpipes.
Of course there can be some difference in heat transfer capacity of different heatpipes.
And every heatpipe adds cost so heatsink with more of them might use cheap heatpipes.
Six heatpipes sure don't help Matterhorn in this comparison:

Cryorig H7 again has awkward installation which might affect also performance:
"Fitting the H7 is a bit of an odd experience, as unlike most coolers, the work is actually done on the reverse side of the motherboard. Essentially screws are pushed through from the rear, which after adding spacers locate directly into the variable geometry mounting arms of the X-Bar system which are fixed to the cooler. Once fitted, we could still feel a bit of torsional play in the cooler which to us indicated it wasn't clamped as tightly down on the CPU as it could have been."
That just three heatpipes might show in this:

With 4770k at stock Cryorig H7 beat NH-U12S coming 1C behind Macho 120. (heatsink fins working better with fan at lower speed?)
With overclocked CPU and increased heatload NH-U12S picked up falling in line with Macho 120 while Cryorig H7 fell behind with 2C difference to Macho 120.
