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.

Zalman Reserator3 Max

Like the Water3.0, the name of Zalman’s Reserator3 Max can be spelled with or without a space between the primary name and its version number (as Reserator 3 Max). Also like the Water3.0, the Reserator3 Max is designed to fill the rear-panel exhaust vent of most high-performance tower cases. The similarities end there, though.

The Reserator3 Max includes only one fan, but its radiator can be installed over a cases's original 120mm exhaust fan. And rather than use a rectangular radiator, the Reserator3 follows Zalman’s iconic radial-fin design, which was made popular on its air coolers. The big change from socket-based Zalman coolers is that the heat sink’s pipes are completely filled with liquid and connected to a remote pump.

Since the radiator isn’t mounted directly to the CPU, there’s no conductive tube in its center. We instead find a hole with fan-mounting screws.

The Reserator3 Max pump housing uses a finely machined and semi-polished copper disc to assure excellent contact with CPU heat spreaders.

    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
