This guesswork is groundless: the Archon is designed right for tall RAM heatspreaders, so, unless you're using miniITX (where YMMV), it will never interfere with any DIMM socket (the fan will be at least 1.0cm far from it).
I would have expected the same thing, but the P67 motherboards aren't laid out like the 1366 and 1156 boards. It appears the RAM slots are closer to the socket. I've been talking with someone who has an ASUS P8P67 and the Archon. He's pretty clear that the fan on the Archon overhangs the first RAM slot and I had him measure the distance from the PCB to the bottom edge of the fan in its default location: He got 37mm with 2-3mm of play in vertical placement of the fan. Ripjaws-X are 40mm high.
It's not guesswork. It's based on real world measurements from people who are physically holding the items in question.
The Archon was designed for tall heat spreaders in 1366 and 1156 motherboards. 1155 motherboards are slightly different.
The MUX is in itself 3mm deeper than the Archon, to be fair (so it should give you equal or worse clearance).
Not according to Thermalright. Both are 53mm deep. Okay, the MUX is 53.44mm. See the diagrams here
. More importantly, note that the MUX has an additional 4mm of vertical clearance to the fin stack and no adjustment for fans, since 120mm fans do not hang below the bottom fin. This would mean that the MUX-120 would clear Ripjaws X by 4-8mm, even if it totally overhung the first RAM slot.
The original MUX-120 was a mediocre cooler for the price, somehow about on par with the venerable, original Ultra-120, somehow an 1156 variant of the much cheaper Cogage True Spirit.
Indeed. The MUX-120 is essentially a True Spirit with a better finish on the contact surface of the heatpipes and the TR pressure vault. SPCRs own testing shows that the True Spirit outperforms the Hyper 212+, especially at lower fan speeds. The Hyper 212 would have an advantage for hotter CPUs with its greater surface area, but that wouldn't be Sandy Bridge. Instead, my concerns are over the overall heat within the box and keeping the CPU cool with minimal noise. Other sites have shown the MUX/True Spirit outperforming the Hyper 212 by a greater margin when looking at at CPUs like the i5-760, which is closer to the i7-2600k than the i7-965 Extreme that SPCR used.
On the other hand, the MUX-120 usually (I mean, apart any possible deal) costs twice the Hyper 212+.
...Otherwise, you would spend twice for a very good mounting mechanism and a mediocre cooler. IMO, of course.
Understood. The reality I'm looking at isn't so lopsided. I'm finding prices for the Hyper 212+ at $35 with shipping, the MUX-120 is $50 with shipping. So, the difference is just $15, and even then, the Hyper 212+ still slightly interferes with the first RAM slot (photo proof
If I wanted to be super economical, I could just run the stock heat sink and still hit 4.4GHz. $35 will get me the Hyper 212+, 4.5GHz (which is as high as I'll go), and much less noise. $50 will get me the MUX and reduce worries over installation while providing slightly better performance. $60 (effectively) will get me the Archon, which is probably the highest performance I'd actually notice.
