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.

    If you don't mind temps howering in the 70C-75C range the h100 can do it passive mounted externally in a horisontal position in a 25C room.

    Just did an hour of LoL. It wont do prime95 for more than 10 min. however. So heavy loads is a nogo passive. And a silent fan doesn't make any noice so i'll switch mine back on. Was a fun experiment though.

    "We could hook up our video cards and CPU to the loop."

    This part doesn't make logical sense. If you "hooked up" multiple heat generators to a coolant loop, only the first one would get cooled.

    Page 3, last sentence of the 1st paragraph: I didn't have any filament problems....
    I'm guessing fitment is the word you intended.

    Hey, someone has to pick at this stuff...

    what was the ambient temp of the room on average? just curious to see what your actual temps were...
  • compudaze - Tuesday, November 8, 2011 - link

    Ambient temps were 22.2C - 24.8C with an average of 23.8C.

    It's been a while, that most power hungry part of the system is a graphic card.
    What a pity they don't make water cooling solution for them.

    I don't quite get why on earth I would install this thing, if I still have to care what to do with graphic card heat.

    Cool IT does make a sealed solution for video cards.

    It's good to see these coolers get to the point where they are really good, even if the cost is a bit high still. I think pretty soon, liquid coolers will be the thing to use in all but inexpensive systems.

    I'm not sure the H100's price is too high; it depends on what a serious overclocker wants, and whether it allows more room than something like the Silver Arrow. Adding another 2 fans will make even more difference (and add to the cost), which will give more of a performance edge to it. Theoretically, anyway, air flow through the radiator may not be the limiting factor in the system.

    I use the CoolIT Eco on one of my rigs (similar to the H60). It's a decent cooler, but the main reason I used it was because I needed a lower profile solution with my Antec Skeleton "case", and these type coolers really work great for that. Of course, you are just moving the space issue to a different location, since there's the radiator to deal with, but that's not an issue with the Skeleton since I just made a bracket to hang it off a side.

    Shame corsair didn't show off the "Corsair Link" kit and demonstrate its abilities. I guess they don't want to sell too many of those $100-129 (USD) kits. Sounds like the Bob's Rug Syndrome (GTE)

    I tried the H60, but at 4.5 Ghz the temp was 8 degrees C hotter than my Cooler Master Hyper 212+. under load and at idle. What I really noticed was how much slower the temp reduced when going from full load to none. I really wanted to like it, I even tried remounting, ensuring thermal compound was applied correctly, etc. I used the same compound for both coolers. My case is a Haf-X with plenty of airflow.
