Conclusion

Finding the right balance between cooling performance and noise is definitely a challenge. While traditional air-coolers continue to grow in size and weight to deal with this problem, Corsair fights it from a different angle with liquid. All of the Hydro Series coolers tested today are perfectly adequate at keeping our overclocked Sandy Bridge system cool. Picking a cooler that's right for you basically boils down to cooling performance, what noise level is acceptable, the price you're willing to pay, and compatibility. Corsair did a great job with these coolers in providing many different options to cover a variety of needs.

The H100 provides excellent cooling on the high setting at the expense of noise. This could potentially give you the extra cooling for when you need to crank up the clock speed to try and beat your friend’s score in the latest benchmark (or whatever it is you’re doing). Thanks to the built-in fan controller, you can choose medium or low speed for reduced noise on your day to day overclock. The only major downsides to the H100 are the limited amount of cases that are compatible, and of course, price.

With the H80, you get great cooling with the same ability to turn the fan speeds up or down depending on your needs. The performance penalty compared to the H100 is easily made up in case compatibility and price. With its push/pull design, even the H80 on low speed is a reasonable contender for most needs. You may be wondering why I mention price here when there's a mere $10 difference between the H80 and H100. Compatibility is probably the number one factor in deciding between the two; however, with sites like Newegg listing the H80 at $93.99, price difference becomes more considerable.

The H60 may not be the coolest kid on the block, but it is a good, cheaper alternative to the H80. The H60 doesn't come with a second fan for push/pull or have the built-in fan controller, but the price is much lower. For those with a limited budget and/or need for a cooler with a low foot print, the H60 might be up your alley. Keep in mind, the H60 is still adequate enough in cooling our overclocked test system.

One final area to discuss is how these liquid-coolers compare to a high-end air-cooler. We included the Thermalright Silver Arrow in our results, and it’s one of the best performing air-coolers on the market—with a price and size to match. In terms of performance and noise levels, the Silver Arrow is probably the best option out of the tested coolers. You can pick one up for around $75 online, which is only slightly more than the Corsair H60 and about $18 less than the Corsair H80; the Corsair H100 is the most expensive, but even then you’re only looking at around $100. What you get for the additional $15-$30 isn’t always better performance, but installation of the Corsair water block is substantially easier than that of the Silver Arrow—and that’s assuming you have a motherboard and case with sufficient clearance to begin with. There’s also the lingering question of whether it’s a good idea to have 1.2kg of weight hanging from your motherboard. Considering all of this, while coolers like the Silver Arrow can certainly be competitive, there’s still plenty of reason to consider Corsair’s Hydro series coolers.

Do any of these Corsair coolers give us the perfect balance of performance and noise? If one cooler stood out against the rest, it would have to be the H100. With its amazing cooling ability, built-in fan controller, and the option of adding two more fans for push/pull, I think Corsair has covered almost every possible situation with this one cooler. You get great cooling performance and low noise, though not at the same time. All of this greatness does come at a pretty steep price, leaving room for the H80 and H60. With high-end air-coolers delivering near-H100 performance at a lower price, it's definitely a hard sell, but the H100 still easily gets our recommendation as a more versatile cooling solution. Just remember to pair it up with an appropriate case.

    "Each Corsair Hydro Series cooler is mounted to blow air from outside the case over the radiator."

    You can always mod your grill like this: http://i.imgur.com/FQiID.jpg -- but you're right, it sucks and you shouldn't have to do that.

    Then this would solve the compatibility issues right from the start...

    Kind of disappointed you didn't open the coolers up. I'd like to know just what kind of build quality one can expect; whether it is deep-fried korean junk, or pristine japanese craftsmanship. It does a lot to ease the mind.

    Why isn't anyone making a "ready to use" closed circuit cooler for gpu's ?
    My gpu needs watercooling more than my cpu.
  • ggathagan - Monday, November 7, 2011 - link

    It's a matter of market scale.
    You can accomodate any CPU from the last 5 years with a single design and two styles of mounting mechanism.
    For GPU's, there are too many variations of design that would have to be considered to make it anywhere near as profitable.

    I rather like these kits. They are a lot worse than a custom loop but for someone just starting on water cooling they are a good introduction.

    Water cooling CPU only is not particularly sensible because air coolers are just as good (although big). A custom loop would cool both CPU and GPU at very least.

    Nice review

    I bought the H80 last month and was less than impressed with the quality of the mounting hardware. Perhaps I've been spoiled with the superb quality found with Thermalright mounting hardware. In any case, the hardware Corsair provides is cheap garbage in comparison. Yes it works, but it's poor quality, soft metal. Hold this mounting hardware in one hand, and typical Thermalright hard metal (and chromed) hardware in the other. It's easy to see which was designed for multiple mounting and unmountings.

    The installation instructions are poorly written as well. I learned more from this article about how the push button affects fan speed than I did from anything Corsair provided. And no words Corsair? Just pictures? You'd think there'd be something written, if anything, a paragraph explaining the push button, or how to properly torque the fittings.

    Other than that, meh, so I got water in my case now.

    I have had the h100 for a year or two now. Could have done with the H60. I don't care about 3-4 degrees difference or overclocks.

    I want absolute silence and water does that. Just need something for my gpu as well. It gets a bit noisy when gaming.

    Big cpu coolers are also silent. However the heat tends to build up in the case and then you need extra fans to move the air out of the case. With water you can place the radiator outside the case with a 900 rpm fan on.

    When my gpu isn't working hard, all i hear is my harddrive. So please, someone make a gpu version of this.

    I don't seehow you had the H100 for over a year, when it just came out this year. It's less than 6 month's old. Try that again?
