Testing Procedures
For temperature testing we load our Core i7-2600K's four cores and eight threads using Prime95 version 26.6. For the sake of consistency, we use the Small FFT stress test. Most likely in daily use, your CPU will rarely reach the temperatures Prime95 and other applications used for stress testing will produce. This should present a worst-case scenario for CPU temperatures and allow us to really see how these CPU coolers handle heavy loads. Due to fluctuations in the ambient temperature during testing, albeit minor, we use delta temperatures to compare results.
Real Temp version 3.67 is used to monitor and log temperatures with samples taken once every second. We run each test for 15 minutes, take the average temperature of all four cores, and use a three minute rolling average to calculate the results. The final temperature is the average of the last three minutes from the test. We then take the final calculated temperature and subtract the room’s average ambient temperature to get our delta temperature. This method has the least temperature fluctuations and is the most consistent.
In addition to the Corsair Hydro Series coolers, we’re testing with Intel’s stock HSF as a baseline, and representing high-end air-cooling is the frankly massive Thermalright Silver Arrow. The Silver Arrow comes with two 140mm fans, with one fan sandwiched between the two large radiator towers. It also weighs in at a hefty 825g without the fans, or around 1.2kg with the fans and clips. Thankfully, it comes with a good mounting solution so as to avoid putting too much strain on your motherboard, but there’s no denying the fact that this is a heavy cooler.
Each cooler is mounted and retested three times to verify good contact was made. We use Arctic Cooling MX-2 instead of the thermal interface material (TIM) that comes preinstalled on the test CPU coolers. There is no curing time allowed between mounts or changing CPU coolers—the MX-2 TIM we use claims not to need curing anyway. These methods help ensure consistency across all tested coolers as well as provide comparable results.
We test each cooler at the Core i7-2600K's stock 3.5GHz frequency, which is the speed it runs at if all four cores are maxed out at 100% and Turbo Boost is enabled. For testing purposes, we disable Turbo Boost and manually set the clock speed to 3.5GHz, with Hyper-Threading enabled; the stock speed runs at 1.16V. We also perform the same set of tests with the CPU overclocked to 4.8GHz using 1.4V, again with Turbo off and Hyper-Threading on.
For noise measurements, we use a Check Mate CM-140 SPL meter. All noise tests are conducted between 1 and 3 AM to ensure the lowest possible ambient noise. In our test environment, we measured ~29 dBA with the test system turned off. Before and after each noise test, the same ambient ~29 dBA measurement was verified. We measured 1 foot away from the test chassis with all doors installed. Our goal is that this method for measuring noise will best mimic a typical usage scenario, though obviously the choice of case, power supply, and graphics card also plays a role.

What advantages bring Closed Liquid Cooling solution. Yes big air coolers like Noctua DH-14 or Thermalright/Cogage Silver Arrow (using one of those) easily outperform CLC. But nobody is thinking about how much problems such big radiators bring to your life. Not everybody own case with horizontal motherboard (I do). In standard vertical mounting bolting 2kg to motherboard is a risky business. It can easily bent, brake and destroy brand new and spangling board you just bought. Need some work to reduce stress on the motherboard. From my own experience, I had that problem when I went from vertical to horizontal. There was certainly microscopic bent on CPU socket because short time after switching when board warmed up everything crashed to hell. Screwing everything even tighter helped for a week, but then whole circus started again. After replacing the board problem was gone, but that is the possible problem with humongous radiators. On the other hand CLC are small, weight very much nothing, performance is very good, often on par with extreme air coolers. Of course standard open LC is better option but it cost much more. If you don't do extreme OC and all what you need is excellent cooling for affordable price with minimum clutter around CPU socket then CLC is simply UNBEATABLE! Simples.What I don't like about these Corsairs is that stupid LED display on top of them and that you need to replace fans for something really useful (well all CLC have this problem).
As for why big air coolers still outperform CLC answer is fairly simple: Radiator thickness. 27mm is very thin for an radiator in liquid cooling setup. If they put 50+mm one day then air coolers will be dead. And I mean D.E.A.D.

If you don't do extreme OC and all you need is excellent cooling for an affordable price expensive CLCs or expensive big air coolers are easily bested by fairly simple parts. If there's no extreme OCs any of the price points offered by corsair for CLCs are more than you should spend really and price/performance wise the CLCs are actually pretty poor performers relative to standard air coolers. The only thing CLCs really offer are space savings, they trade space around the CPU for space around an exhaust fan which is some chassis is a very good thing.Beenthere - Monday, November 7, 2011 - link
Exactly. Those were my points. The CLC's are a poor value, inefficient and over-rated. One leak can cost you hundreds of dollars is damaged PC hardware.Mediarocker - Sunday, December 18, 2011 - link
Inefficient? Hardly. They perform as well as most air coolers, with the exception of the giant Noctunas and ETC. but when it comes down to it, and you need space savings these are perfect for the job.So no they aren't of a Poor Value, and aren't inefficient and over-rated. They just don't belong in YOUR market segment.
Just because you don't have any use for it doesn't mean that they don't have a place to belong.
Nevertheless these CLC's won't leak as easily due to there being less user error. The CLC's are sealed shut. So leaking is highly improbable without there being some abuse involved, E.G. taking a screwdriver to the rad accidentally.
Take your fears elsewhere. It's been established that you are afraid of liquid cooling and prefer air cooling. That is entirely alright, but don't dismiss the merits of CLC cooling just because it has no use for you.

All-in-one's from Swiftech (latest rev H20-220 etc) & similar specialist vendors are far better performers than the H100.And they're more flexible when it comes to adding your own tweaks/improvements etc.

Pop over to xtremesystems where everyone talks about nothing but water-cooling.And they'll recommended it any day over the sealed loops from Corsair.

Why not include some good cheap air heat sinks as well for comparison as well? I really don't see how this is recommended by Anandtech, very expensive with no major advantages along with added complexity and danger of leaks. It also seems impossible to refill these if they are losing liquid? They do have nice 5 year warranties but I suspect most air heat sinks will last much longer.Iketh - Monday, November 7, 2011 - link
heat pipes would need refilling if they leaked too... your point is mootkyuu - Monday, November 7, 2011 - link
Part of the whole point of closed-loop (these) vs. open-loop water-cooling is that they are much less complex (from the article, it seems that they're actually easier to mount than many traditional air HSFs), and, since they're sealed, there should be no danger of leaks (unless the unit is defective, in which case I'd assume the warranty should cover replacement of any damaged components). And of course it's impossible to refill them... again, they're sealed. You shouldn't have to worry about loss of liquid for the same reason.Personally, I love the idea of the CLCs (water-cooling performance without the expense, trouble, and risk of an open loop water-cooling setup), but unfortunately it's just not there yet. While it does provide a good alternative to mounting bulky, heavy air-coolers, you still have to pay a premium to get merely competitive performance with cheaper airs.
Hopefully, soon they'll be able to get these to outperform air-coolers as a water-cooler should.

Maybe I missed it, but I see no mention of fan direction / configuration. For the H60 in particular it is important to mount the fan to push into the case/radiator.The H100 + 600T is really not the best test for that cooler. I reported this to Corsair tech support after I bought the combo, and they wouldn't even admit there was a problem. The grille between the top slot and the radiator causes major turbulence if you mount the fans to push into the case the fans vibrate like crazy. I had to do the same thing Jared did, leave the top grille off. Unacceptable for the money spent, considering Corsair claims compatibility. They were no help, though.
I opted to buy a 650D to move my rig into, but Corsair messed up with the 600T. Most of their other cases are perfect for the H100, though.
I'd like to see AT test the H100 without that inefficient 600T grille, in a case that actually sets up for it like the 650D.
