Conclusion, Part 1: Corsair

With the results at our disposal, we can now evaluate each cooler on its own merits. The charts can tell us how good the coolers are at their jobs and how quiet they are, but it's also about price and value included in the package. This year's H80 boasts a major improvement over last year's in terms of both the fans used, but also the fan control, which is now a much more convenient software solution.

Corsair H55

Corsair's budget offering actually turns out to be one of its strongest. The H55 is as no-frills as it gets, but boasts a solidly performing fixed-speed fan and a respectably low price tag. You can have it for just $59, which is extremely competitive for a closed-loop liquid cooler. While no one would really argue that $59 is "cheaping out" on a processor cooler, this is nonetheless a good choice if you're on a tighter budget.

Corsair H60 (2013 Edition)

Unfortunately, part of the reason the H55 looks so good is because the H60 performs so poorly. The H60 runs $10 more than the H55 for an arguably better PWM-controlled fan and a somewhat lesser quality waterblock. In this corner of the market, there's really no legitimate reason to spend up on the H60 when the H55 performs as well or better for less.

Corsair H80i

The H80i is the other big winner in Corsair's lineup. While it's not an absolute killer in performance or in price, it does beat NZXT's Kraken X40 while being more compatible with different cases due to use of a thicker 120mm radiator and dual fans as opposed to the thinner 140mm radiator and single fan. You also benefit from the Corsair Link interface and software, which allows you to connect either a fan controller or an "i" series Corsair power supply to the waterblock and control them through the software. Corsair Link is much, much more robust than NZXT's solution, and Corsair has been steadily updating it since it appeared at the beginning of the year.

Corsair H100i

Inexplicably, Corsair's flagship dual-length solution is only able to at most achieve parity with the H80i. You can theoretically produce superior cooling performance by adding yet two more fans to the H100i, but you become increasingly at the mercy of your case's clearance, already an issue just by virtue of going with a dual-length radiator like this one. At the time of this writing, NewEgg is selling the H100i for cheaper than the H80i, so they may know something there as well. Either way, the H100i is a very hard sell when the H80i provides both better value and better compatibility.

    Just a correction. The idle/load graph bars are swapped. According to the graphs they run hotter and louder at idle.
    Otherwise an awesome review.
    Thanks muchly.

    I don't get the rationale of using no GPU and an ITX motherboard for this review. IMO, you should have used a big motherboard like a MSI Z77 Big Bang. The possibility of fitting these coolers in the desired configuration remains to be the biggest key concern for any buyer out there. I bought a H100 last year, couldn't fit it in push-pull configuration in my case, had to "downgrade" back to H60. A quick google search will tell you that there are very few cases that can actually accomodate H100 in push-pull configuration. And i suspect the X60 might run into the same problem. So, i believe the space saving by having no GPU and an ITX motherboard was the wrong way to do this review. And why not use an ivy bridge CPU? They run hotter than sandy and i'm sure we'd all like to see these coolers getting pushed as far as possible.

    Besides, there aren't many people who'd buy a ~100$ CPU cooler but no dedicated GPU. So, the added heat from the GPU would have been a welcome addition to these test results.

    The form factor of the motherboard is irrelevant to the results.

    Removing the GPU allows me to isolate the radiator performance in a more absolute way.

    It's true clearance is a serious issue for the double-length radiators in push-pull, but they don't seem to *need* to be run in push-pull either.

    As for Ivy Bridge, I didn't have one on hand to test with. I did have an i7-2700K, and that's what I tested with.

    I agree that the form factor doesn't affect the result significatly, but as i pointed out, getting these coolers to fit in the case is the single biggest concern and it should have been a part of the study as well.

    More absolute, yes, but testing with a GPU will fetch closer to real world performance. Besides, same GPU in the same case won't really skew the result at all, would it?

    They kinda do "need" push-pull config. The effect is drastic. That's the sole reason that the H100i performs lower than H80i in this test. The thicker radiator obstructs airflow and has a negative impact on cooling. Not using the H100i in push-pull sort of beats the purpose of buying one in the first place. Your review supports it as well, H80i is a better buy than H100i if it's gonna be used in pull only config.

    Fair enough, although i imagined anandtech benching facility would have hundreds of CPUs just lying around :P

    It would be difficult to have the GPU hit the same thermal profile every test. Removing it much easier to isolate the effects of the different systems without worrying about what the GPU did that run. Reply

    The whole cooling part of the review should have been done bare bones with no case. As is, the results are specific to this situation only with this case and not only based on the actual cooling performance of the cooler alone. A second section of the review could then cover how these fit into cases. This case may have minimized the affect of a case but its in not a true measurement of just the cooling capability. In fact, it's just more work for the reviewer installing all of these blocks to a case/motherboard. Reply

    Agreed. What we have here is half way between real-world and raw performance numbers. Reply

    Frankly no one needs push pull. It is all about looks with just about no gain. Frankly I do not like the looks but too each his own. As too motherboards size that just doesn't matter. Ivy bridge vs sandy bridge also just do not matter. Heat is heat. The best cooler will still be the best cooler.
    To do the test in as pure of a way possible they should have just mounted the cooler not to a CPU but to a hot plate putting out a known amount of heat. The issue with that is both of these systems have a software controller so you do need to run them on a live system.
    As to motherboards and clearances well there a lot of motherboards and cases, They can not check all of them. I would have liked to see them use a Corsair case for the Corsair coolers and an NZXT case for NZXT coolers.
    Overall the way they did the tests were very good for the time and resources they have available. As to adding a GPU that would only be useful if they used the exact same case, card, and power supply you were going to use.

    It's a CPU cooler why do people have to have a gpu to overclock to CPU. You do realize not everyone plays games and spends $200+ on a gpu. Also who cares what CPU he uses its an apples to apples comparison not a how to cool an sandy bridge article. Its not an installation article so who cares if he uses a smaller board which always it too fit. Do you really expect him to go through all thr case/motherboard comboss telling you what will and wont work? Again its an apples to apples review as long as they were all run in the same setup thats all that matters. somehow you dint understand this. You don't make 1 single good point. Reply

    I've never been a fan of closed loop systems, mainly because the performance isnt any better than a highend air cooler, but it seems a little ridiculous to have such a big radiator and 2x 140mm fans to cool a modern CPU.

    I could see a need for them in 2006 but not 2012. I have an air cooler with 1x120mm fan and I have silent performance at idle and at load, that with a 3770k @4.4ghz. I dont have to install software or set fan speeds. Once installed it takes care of itself. This cooler has been on 3 system upgrades, I just dont see the attraction, especially when it limits your choice of case. What reason is there for me to dump my aircooler for this huge radiator setup? Even with 2x120mm fans?

    Its a lot of hardware just to cool a CPU, it seems less efficient and the performance isnt any better than a highend air cooler. With double the cooling area, these radiators should be performing at least 50% better than an air cooler, but we find they perform about the same as a aircooler with half the cooling area. it would have been nice to see a aircooler in the comparison btw.

    It seems like efficiency is going backwards with these closed loop systems.
