Conclusions, Part 1

While the Deepcool coolers were unique in their own ways, the conclusions I came to with them were basically the same. Most of them were fairly underwhelming with little to really recommend them, and today's testing pretty much puts the final nail in that coffin. None of them really stand up particularly well to the already widely available Cooler Master Hyper 212 EVO. The Deepcool Frostwin continues to be the highlight of their lineup, but if you need to go lower clearance than that, Noctua certainly has you covered.

I'm drawing conclusions on the individual coolers because each one arguably has something to offer in its own right that goes beyond absolute performance.

Noctua NH-D14

The Noctua NH-D14 performed admirably, and if for whatever reason a closed loop cooler isn't on your list, the D14 is about as good as it gets on American shores (at least until we get hardware from Prolimatech or Thermalright in for review.) SilverStone's Heligon HE01 can hit the same performance levels, but it produces much higher noise in the process. You'll pay a pretty penny for the NH-D14, but it definitely feels like a quality cooler. Installation is sturdy, and performance and acoustics are very good.

Noctua NH-L12

The Noctua NH-L12's performance isn't exceptional, but it has one very important ace in the hole: it has a fairly low profile. In situations where a tower cooler simply isn't going to be an option, Noctua's NH-L12 offers decent performance and excellent acoustics. With the 120mm fan installed, the cooler's height is 93mm; remove it, and it's down to just 66mm. I also experienced no clearance issues with the NH-L12, even on the fairly crowded mITX board used for testing.

Noctua NH-L9i

While the other coolers definitely have something to offer above and beyond the Intel stock cooler in every way but clearance, the Noctua NH-L9i is a tougher sell. Essentially what you're paying for with this cooler is maximum compatibility and superior acoustics to the stock cooler. For many users that may very well be enough, but I suspect for a lot of people the price tag is going to make it a hard sell. At that point you may very well be better off looking to spend up on the NH-L12 if cooling performance and clearance are going to be sticking points.

SilverStone Heligon HE01

As a longtime fan of SilverStone's stuff, I approached the Heligon HE01 with some trepidation. Reviews for it elsewhere are generally favorable, but none are effusive. That typically means that the reviewer is being diplomatic. SilverStone's entrant doesn't perform poorly, but unfortunately runs into one major problem: nothing about it really recommends it over any of the other options available. If you're going to spend this much on an air cooler, you might as well go whole hog and grab Noctua's solution.

    I actually imagine that in the 240/280mm closed loop coolers, there's easily more than .25 liters of coolant. Perhaps even approaching a liter or more, depending on the size/density of radiator piping and the tubing.

    If your numbers are closer the accurate, than that's a fair enough way to say 15 minutes is likely enough, but still, I'd like to see 30-60 minute tests for the best performers, or even longer. Run those 280mm radiators for 1-2 hours and see how much/if at all that affects performance. Because on that slight change that it -does- affect it significantly, these numbers posted in the review are absolutely meaningless and misleading.

    Well, interesting results to say the least. Tom's Hardware and X-bitlabs have reviews up as well comparing aio's to NH-D14 and Phanteks PH-TC14. Their results are quite different from this. For example in the X-bitsreview the H55 is easily beaten by PH-TC14 but here the H55 does better than the NH-D14. Something's not right, and it's probably called outtake fan.

    Just remember that there are a lot of variables in different entities testing the same cooler, not the least of which is hardware including the case itself, and the success of how well the coolers are attached to the CPU with paste to minimize gaps. Then you have ambient temperature and altitude differences, etc. I wouldn't trust one review to be better or worse than another review of the same cooler. You are better off trying to find a pattern among all the coolers tested you are interested in and see which one mostly stays on top.

    Well, yes that's the reason I comment. I read many cooler reviews and I'm aware you can't compare them on an absolute basis, too many outside variables for that. But the results of this one have me scratching my head. This is simply the first time I see an aio like H55 do better than the NH-D14 and it just doesn't make much sense to me. I mean, look how thin the H55 radiator is and then look at the massive 1 kg of copper and aluminium which is the NH-D14. Ok, so H55 has higher rpm fan, but the dual fan setup on the NH-D14 counters that.

    Also, Hyper 212 is a nice heatsink if you can get it around $30 but just 1.6 degree difference vs NH-D14? Which weighs like twice as much and has 2 fans, one even a 140mm model? Maybe using the NH-L12 bracket isn't so ideal afterall (also might be nice to mention regular NH-D14 doesn't come with pwm fans).

    I wish you'd included the Phanteks PH-TC14PE. It's cheaper than the NH-D14, looks nicer
    and in many reviews performs better.

    I've been loving my NH-D14 on a 4.8GHz 2500k for two years solid now. Even in summer indoor ambient temps of 80F (27C), it never gets above 55C at that high level o/c running 1.38v. Of course the modded Antec Nine Hundred it sits in has excellent airflow too.

    And two years ago I paid $85 for the thing, so the price has not come down at all, which speaks volumes about the continued demand for them. Best $$ I ever spent under $100 on a piece of hardware.

    I don't get all the bias of the reviewer against the NH-L9i, yeah for normal PC use its pretty much useless, but thats not ware its made for.

    Its a HTPC/small form factor cooler, and it fits in to places ware its big brothers don't fit, its real competition is the Scythe Shuriken series and some other low profile solutions.
  • Lycros - Saturday, March 16, 2013 - link

    Anyway you can use the same fan(s) across all of the heatsinks next time?
  • ellroy80 - Sunday, March 17, 2013 - link

    Dustin, your review of the NH-L9i is really not fair. It states on the Noctua website that "The NH-L9i is a highly-compact low-profile quiet cooler designed for use in small form factor cases and HTPC environments. While it provides first rate performance in its class, it is not suitable for overclocking and should be used with care on CPUs with more than 65W TDP." So your usage scenario is really not applicable to this cooler. Any chance you could re-test it with, say, an i3-3225?
  • lichoblack - Monday, March 18, 2013 - link

    I have to agree that the review paints the cooler in bad light, but instead of using another CPU, I'm more game with changing the restrictions: test small coolers and see how they fare. The NH-L9i/L9a have a very low height, and you can use them in very, very restrictive cases (thinking of an htpc/emu case using a Lian-Li PC-Q12, then you can only use a cooler up to 55mm, so you can use a stock intel fan, but not an AMD stock fan. see:http://www.lian-li.com/v2/en/product/product06.php... Not many coolers fit this bill, and big air just doesn't fit this. CLC could, depending on the case, but big air can't. So more small aftermarket coolers so we can better paint the small air picture :)
