Performance Results

Given that I've been doing these cooler reviews entirely in roundups, it's probably no surprise that the amount of results I've put together have absolutely ballooned. So much so that including all of the results in every graph would result in some very, very long graphs. With that in mind, for the master list of coolers (including all of the results from the current roundup), I'm only including what I feel are the most balanced results for a given cooler. I'm taking into account if ratcheting up fan speed doesn't produce much of a difference in performance, or if ratcheting it down makes a huge difference.

Results in black are for coolers that actually failed testing.

Cooling Performance

Out of this roundup of coolers, the three big boys put in the best performance overall, tying or beating Deepcool's flagship Assassin. Unfortunately, they have to run at full bore to really start to nip at the heels of the closed loop coolers. None of them are bad coolers, but the metrics I'm using here really don't tell the whole story.

Acoustic Performance

The nice thing about these new coolers is that none of them are really that loud, with the exception of SilverStone's HE01. The fan Cooler Master employs on the Hyper 212 EVO isn't particularly quiet, but at full bore it's still fairly easy to ignore.

In the midst of all these results, it's unfortunate that Noctua's NH-L9i pretty much has to run at full bore to be usable. It's a definite improvement on the Intel stock cooler, but you're still not really going to be doing any overclocking with it. Its chief advantages over the stock cooler are going to be its lower noise level under load and superior mounting mechanism.

    How do you measure thermal efficiency? Just by how cool it gets the cpu? If so then CLC's do well.
    Noise wise, has a lot to do with the fans and can be very similar to other coolers.
    Cost? They are a bit expensive but their ability to cool well and also exhaust heat directly out the case is typically enough justification. I mean we are only talking about maybe $20 max, far less than a tank of gas even.
    Reliability? I have had two in service for quite a while now and they have been fine but I can see how adding a pump into the mix is a recipe for lowering overall reliability potential.

    However the simple fact is water moves heat better than heat-pipes, period. So you can move heat to a larger radiator, and also put that radiator in a larger variety of places. That is why even the small closed loop coolers do well. I have built several full custom loops in the past, and the closed loop coolers are not nearly as good as a high end custom setup, but FAR easier to get going and little to not maintenance. They have their place IMHO. They are not perfect but they definitely have their place.

    Do you have any facts or reasons behind your statement or are you just saying stuff because it sounds cool? Maybe your idea of technically astute is incorrect, or you are simply not technically astute yourself.

    Of course there is the downside to water coolers. They are spot not area coolers. Air will cool everything (to a certain extent) in the case as it flows over it, water will only cool those spots which have a waterblock.

    That is why you need to have decent airflow in a watercooled case - if not you fry the RAM (and yes I have done that)

    A few years ago I saw a CPU waterblock by a low-tier vendor that had brackets for a down blowing fan on top to keep the ram/mosfets from baking; and have always wondered why none of the other vendors have ever offered anything similar.

    I would love it if there were a way for the noise to be recorded so we can listen. Sure dBA numbers are great, but the actual pitch of the sound emitted is very important. I also have a hard time translating dBA numbers into perceived sound increase. I have a Noctua NH-D14 and according to your charts, there is only a 2dBA increase from silent to 100%. I would have guessed it to be MUCH larger than that as the perceptible sound increase from silent to 100% in my rig is massive. The pitch/tone of the sound (if that's the right terminology) at 100% changes drastically too.

    Here in Europe the DarkRock Pro is typically 1 to 2 euro's cheaper than the Noctua NH-D14, sometimes a bit cheaper even, if you can be bothered to look around. The new BeQuiet Shadow Rock also performs quite well imho, haven't used it myself but it's the cooler we put in budget systems at the shop whenever coolermaster EVO's aren't available.

    We used the original Dark Rock Pro for an ASUS S2011 contest early last year, and it was quickly overwhelmed by the heat generated from the CPU past 5 GHz. So much that we had to force extra pressure on the socket so the processor didn't downclock and bork the scores.

    Good review. The only thing I would suggest would be to also use a test bench for testing the coolers so you can take the case out of the equation. I would still test in a case as well but pick one you really like to build in because you will need to do it forever. Of course maybe you have.
    Now you just need to test every cooler in every case and with every CPU. Can you have it by next week?

    No sorry the Plus' fan is better than the Evo's fan.

    What about comparing low-profile coolers with some CLC's? Given the new trend towards smaller cases, and the height restriction of those microATX (Thermaltake LANBox for instance) or microITX cases (a LianLi one has 38mm height restriction, fitting for the noctua reviewed here) it would be interesting to compare a CLC to a compact cooler that has to be smaller than, say 100mm height.

    Good stuff. I hope you add the Thermaltake Water 2.0 extreme to the mix.
    I moved from D14 to it and love it.
