Four New Closed-Loop Liquid Coolers Versus Noctua's NH-D14

Four new closed-loop liquid coolers seek to improve thermal performance in a number of ways. We certainly understand the benefits of these configurations, but can they out-do the reigning air-cooling champion, Noctua's NH-D14? Check out our benchmarks.

Cooler Master Nepton 280L

Drilled to support both 140 and 120 mm fans, Cooler Master’s Nepton includes the widest radiator in today’s comparison. It includes two of the company's 140 mm x 25 mm fans, a power splitter, and an installation kit.

The Nepton 280L fits all popular four-hole CPU cooler support systems, including AMD’s rectangular and Intel’s square patterns. AMD installations require the original bracket to be replaced with Cooler Master’s universal version, while custom standoffs fit LGA 2011’s original bracket.

The Nepton 280L’s copper base is finely sanded to provide great contact with all current CPU-integrated heat spreaders. Only a thin smear of thermal compound is needed to complete that coupling.

Separate top brackets fit either AMD or Intel sockets. The Intel version is drilled for LGA 775, 1150/1155/1156, and 1366/2011. These brackets are threaded for mounting screws and slide into slots on the side of the base/pump housing.

    length, width and thickness in inches, fan size in mm, weight in ounces. can we just have mm everywhere, and preferably kg as well?

    Seems they reduced their old BS claim of handling 400 watts of heat on the Reserator 3 MAX, it is now 350 watts, but even that seems unrealistic.

    Tomshardware should place some of these coolers on a resistive load of 300-400 watts and see if these coolers can actually handle the heat, or will the fluid boil and build up enough pressure to pop.

    Isn't the whole point of watercooling to move the cooler far away from the cpu, so that there is more room to utilize a significantly larger radiator? The thermalright and zalman options look smaller than the noctua...

    Grabbed a Dark Rock Pro 2 for my new setup. No regrets - looks a billion times better than D14, is less noisy, performs +-1C the same.

    got an old corsair h100 for $50, which was less then the old heatsink i had on my phII x4 965 used to go for (thermalright ultra 120), Gained a solid 8C improvement in temps, lost some of the noise advantages (the ultra had two noctua's on it)... setting it to medium gave me a 5C improvement in temps, and about the same noise levels. overall i'm pretty happy with it. it looks cleaner, that's for sure.

    Thanks for the review.I always have said if someone is going to watercool they should go custom.IMO those all in one water cooling kits just are not worth it. They are no better than high-end air cooling like a Noctua D14, Thermalright Silver Arrow,Phanteks PH-TC14PE elect.If you want to go water cooling do a custom loop if not just go with top of the line air cooling.Better bang per buck!

    I wish there was some way to measure the DeltaT of the Ethylene Glycol used in these CLC's because truthfully I wouldn't be surprised to see >25c when using a overclocked 3960X.

    I wonder how much the rear exhaust fan would have affected the Reserstor3’s results.
    In any case, I will wait for price drops or rebates.

    Is it so difficult to sort the results from best to worst? Lowest to highest etc?

    Like this it is impossible to read.

    Well, those stock fans all blows, in my optic. You might call it cheating, but try slamming in two noctua pwm fans in a H100i for instance. I run this at home, and those fans typically runs at 600-800 rpm, therefore being totally silent. My stock temps rest around 38C, with 22C ambient, and hit around 60C at full prime load. i7 2600K @ 4.2 ghz. 1.28v
