Closed Loop AIO Liquid Coolers: 14-way Mega Roundup Review
by E. Fylladitakis on February 12, 2014 7:00 AM ESTTesting Results, Maximum Fan Speed (12V)
The above charts depict exactly why a user needs to be more than just a little careful when selecting a cooler. Even though they appear similar and some of them even nearly identical, the performance of each and every AIO cooler that we have tested varies greatly. For instance, Cooler Master obviously sought to provide the best heavy-load performance possible and they did manage to reach the top of our charts; however, the noise of the fans that Cooler Master supplied at maximum speed is intolerable for daily use by any standards.
To give you a rough estimate, 56 dB(A) represents about the same level of sound as a typical box fan the same distance. The Nepton 280L is closely followed by the NZXT Kraken X60 and then the Corsair H110, both of which share about the same size and design but not nearly the same noise levels. The NZXT Kraken X60 is over 5 dB(A) quieter than the Nepton 280L, a very perceptible difference, while the Corsair H110 generates only 41.3 dB(A), which is equivalent to a soft humming noise and fairly comfortable for daily use.
Naturally, the performance decreases as we move to AIO coolers with smaller radiators, with the Corsair H100i leading the coolers using 120mm fans but its stock fans run at 2600 RPM, generating high noise levels. The Enermax Liqtech 120X and Silverstone Tundra TD03 and their beefy radiators deliver great thermal performance when compared to other single-fan AIO coolers, although Enermax proved that they could offer roughly the same performance with just one fan and much lower noise levels, making Silverstone's choice to include two fans appear somewhat redundant.
Under a low thermal load however, the charts shift greatly. As the thermal load is much lower, the low temperature dissipation efficiency of the cooler now matters a lot more than its maximum thermal load capacity. Corsair's H100i offers the best thermal performance, outperforming coolers with significantly larger radiators, including Corsair's own H110, closely followed by another 240mm long cooler, the Silverstone Tundra TD02. The gap between the budget-level and high-performance products now closes, with the Corsair H75 being the most notable example, as it manages to outperform its own larger version, the H105. Apparently, bigger is not always better and the lower flow resistance of the single fan radiator gives the Corsair H75 a faster energy transfer rate at lower temperature deltas.

noctua d14 runs cooler and quieter. These all in 1 coolers all suffer from the same problem. The pumps used are cheap loud and not very powerful. You need to build you own water cooling loop using high quality waterblocks radiators pumps and tubing then and only then can u take the noctua d14 down, And I'd still use high static pressure noctua fans on the custom water cooling loop because noctua fans are awesometheNiZer - Wednesday, February 12, 2014 - link
E. Fylladitakis : I like the theme of the article and the approach, BUT did you use the same fan-type for all coolers? If not, that explains the lov efficiency of Coirsair H105 - it has more low noise tuned fans.You should test the units with the same fan as well to really tell the effect of the individual watercoolers.

No and I will never use any other fan than the ones supplied with the kit. I explained why thoroughly in the comments above. I cannot perform tests with a fan of my choice, as the characteristic performance of the said fan will favor some designs over others, creating misleading results. And I cannot possibly perform testing using dozens of fans either.It also increases the cost. Most people simply want to buy a cooler, not half the store. If someone wants to use different fans for whatever reason, I cannot possibly foretell how each kit will react. RPM, CFM, sound pressure levels are all next to irrelevant when a fan is going to be mounted on a heat exchanger, therefore any comparisons between fans that "look similar" are a massive mistake.
I performed noise testing, you know. If you would look at it, it is one of the noisiest kits in the roundup. So that could not have been further from the truth.

Why no thermaltake? I managed to snag a thermaltake performer 2.0 from Microcenter for $5 after a rebate lol last BF. It was too good to be true. They also had the extreme 2.0 for $35. Great cooler too (both of them although i kept the little one).E.Fyll - Wednesday, February 12, 2014 - link
Copy-paste from above:"I know. I actually tried to acquire all AIO coolers in existence, including Intel's, Thermaltake's and others. Not everyone is happy to cooperate and/or willing/able to supply samples at a give time, for whatever reason."
I cannot test what I cannot have access to.

I normally don't comment, but I just have to say that I'm also really disappointed that the Swiftech H220 isn't in this review. In all fairness, one could argue that the H220 isn't a close loop cooler, but the lack of its presence in this article does give it a fowl stench.E.Fyll - Wednesday, February 12, 2014 - link

The H220 isn't *available.* Asetek's litigation means you can't buy it stateside, rendering its performance somewhat irrelevant.twtech - Wednesday, February 12, 2014 - link
I don't see a winner listed, but the results seem to say that, from a performance standard, if you have the room to fit it, the Corsair H110 is what you'd want to buy. It's basically a close 2nd in both performance and noise, which makes it a clear #1 overall.twtech - Wednesday, February 12, 2014 - link
And by standard I meant standpoint.
