How close is too close for CPU cooler clearance?

khawk1 · Jul 4, 2015

Looking at the following case http://m.newegg.com/Product/index?itemnumber=N82E16811146102
the cpu clearance is 160mm. Would like to get the CM Evo cpu cooler which is 159mm. Is 1mm not enough space? Seems like several cases have 160mm clearance.

It should fit.

it under the 160mm in hight..i have this cooler..the only issue with low hight units is getting the ram into the two back slots after the heat sink is on.

Iffy. Some case measurements are not exact.
For instance, the Antec ONE lists cooler clearance at 155mm. However, the CM 212+ at 158mm fits with a teeny bit of room to spare.
All depends on which way it was actually measured.

But..at 1mm reported difference, I probably wouldn't risk it unless I had seen someone else with that exact combo, and it actually fits.

It's not iffy it simply fits (you can also spray paint the top side a different color if you don't like the color before you install it)

How to change the top color. I would recommend some high temp paint like for a BBQ grill.

Agreed, it either fits or it doesn't.

This sentence is the definition of 'iffy'.

Some pictures show it fits others say they weren't able to get it to fit. Can't see manufacturing being off by 1mm ... maybe the motherboard mount height? Sounds like I'm better off going with a cooler under 150 mm .. something like this

Whether it fits or not is kinda moot. It either fits or it doesn't. 1mm clearance is enough in most cases. However, some case sides are a real p.i.t.a to close and require some pressure in the center of the side to get all those stupid little tabs to enter their respective slots. In that case, you can say goodbye to that 1mm of clearance as the case side will flex inwards. It's also possible to use the heel of your palm just like an 'English wheel', from the inside of course, and actually flex the case side outwards, giving 2-3mm of clearance above the cooler.
'Iffyness' aside, the better option would be not to get the Hyper212, very good and very popular budget cooler btw, but to shop around for alternatives such as the Enermax T40, Raijintek Aidos, Cryorig H7 (better by far than the hyper212) all of which are smaller in height for around the same price.

+1. That's the one I was trying to remember for recommendation.

Looks like Cryorig H7 is out of stock at Newegg and not shown on pcpartpicker.com, is this part difficult to find in the US?

Karadjgne :

How does the Cryorig H5A compare to the H7?

The H7, while slightly better than a hyper212 is still in the good but budget cooler range. Then you have full twin towers like the Cryorig R1's and Noctua nh-d14/15 etc. The H5 fills in the performance gap right in the middle of these 2 styles, however, it uses an offset 140mm fan and with heatsink is still 160mm tall. You'd be in the same boat as the hyper212, except with much better performance.

The Raijintek Themis (not evo) would be a good substitute at 157mm

I guess you can't see that the Hyper 212 fits, you let all the iffies cloud the truth when It's right in front of you.

And those pics are exactly what I meant earlier, with : "unless I had seen someone else with that exact combo, and it actually fits. "

Zerk2012 · Jul 4, 2015

USAFRet :

That is the exact combo of case and cooler.

And as you posted that, i was writing my response to the original. Did not see it before I clicked my 'Answer' button.
OK? It fits. Let's move on.

have you thought of putting in a window mounting the plexy glass on the out side will give you that tad bit you mit need other wise you mit get a vibration noise that you don't want

Personally I'd go with the Raijintek Aidos. It's a 92mm fan vrs the 120mm of the 212, is much smaller in stature, usually either cheaper or the same as a 212 evo and either beats it by @1°C or equals the 212 in either idle speed or OC tests.

Raijintek is a newer company, but is made up primarily of ex CoolerMaster and Xigamatek employees, so they aren't exactly clueless wannabees. The Raijintek Aidos has exactly 1 drawback. The fan is red/white which is sometimes a hard sell since red/white isn't a common color scheme.

So, recap, performance = hyper212, price = hyper212, fitment = smaller height than hyper212, and let's face it, reality check, the mounting system of the hyper212 royally sucks, whereas the Aidos is simple and easy.

Enough is enough, the CoolerMaster Hyper212 EVO has had its 15 minutes of fame, there is now better or at least equal options to be had, let's move on shall we?
