Question about CM Hyper 212 Evo

[slpnshot]

I recently got a CM Hyper 212 Evo, and the mounting seemed pretty simple(definitely better than the older HULK SMASH push-pin after market coolers...), but I'm curious what the pin directly over middle of the cpu heatsink is for.

To clarify, the Evo has the X mounting with 4 pins over the socket holes, but on the heatsink itself there is a 'pin' over the middle portion that doesn't seem to do anything...

I tried reading the installation manual, but it was rather vague and didn't even seem to touch upon the middle pin. Just a bit curious if there was something extra I needed to do with that part.

My cpu seems to run find at 28-30 C~ at idle, however I didn't stress test it yet.

I have the previous model, the CM Hyper 212+, which also has the middle pin.

The middle pin doesn't seem to fasten anything. At first I thought it was meant to hold the middle of heatsink cpu in place, but even with all 4 socket hole pins fully screwed down, I can still slightly swivel the cooler.

If your temps are okay I wouldn't be too bothered about it. My overclocked 960T X4 runs stress tests just fine.

The middle pin can be fastened with your fingers. It just provides some extra pressure I think. If your cooler is fixed as it is and your temps are fine I wouldn't worry too much.

are you referring to the off-center pin that i've circled in red?

that little pin functions solely to keep the X-brace lined up w/ the heatsink (so that the heatsink does not pivot/swivel after the X-brace has been fully tightened at all 4 corners). will there still be a bit of play even if you've utilized that little pin appropriately? probably. will it be perfectly immovable afterward? probably not...

its not the sharpest image (courtesy of newegg), but if you look closely you can see 2 small notches recessed into the edge of the center portion of one of the X-brace's arms (i circled them in red) - those notches are what catches on the small pin on the backside of the heatsink. your application (AMD/Intel) and/or heatsink orientation (hot air out the back of the case, or out the top of the case) will determine which notch on the X-brace to line up with the placement pin. the fat pin in the center of the X-brace (which i've circled in green here) obviously fits into the large hole on the backside of the heatsink (which i've also circled in green in the first picture).

I actually meant the screw portion on the other side of the green pin. I get why you need the pin because it securely fits the X mount over the middle of the heatsink, I just didn't get why you could rotate and depress it slightly with the screw.

It's truthfully not a big deal, but on the first installation I spent a good 10 minutes trying to figure out what that screw was supposed to do.

I guess it's just a fallacy of video games. Whenever there is an extra feature, I always assume that there's a reason for the thing being there so I figure I'm doing it wrong if I'm not using it.

oh i see what you're talking about now. as ifar as i know, its still news to me if that thing actually tightens like a screw. the only purpose that i know it to serve is to allow you to change the configuration of the X-brace (to change the shape of the "X" to fit various types of CPU sockets). after all, it is spring loaded, and you have to pull it away from the X-brace itself in order to adjust the two arms that comprise it...otherwise, the two arms that comprise it are locked in place and the "X" shape doesn't change...

 

[slpnshot]

Oh is that what the spring set up was for? Lol.

I was just adjusting the X angle without using the screw pullback at all. There was hardly any resistance for the adjustment so I never even noticed it, just enough for it to stay in place in different 'preset' angles.

Well thanks for clarifying.

I was wondering about this too. I tried screwing down that middle screw on the X bracket, but it didn't seem to tighten... probably safe to ignore it?
