Testing Method
Setup & Methodology

For our thermal tests, we used two air coolers for reference in our CPU temperature tests and the stock GeForce 8800 GTX reference cooler for GPU tests. We chose the Intel stock cooler and a large, heat-pipe based air cooler; the Silverstone NT-06. For all tests, a Scythe S-FLEX SFF21D (800 RPM) was installed on the LCLC's heat exchanger. All other coolers used the fans they are packaged with. The Silverstone was tested twice, once at 750 RPM and a second time at 2640 RPM (max speed for stock fan). All thermal tests were performed on an open-air test bench. All testing was performed with the CPU and GPU at stock frequencies.

Two separate tests were performed. The CPU was stressed with Everest's built-in stress test function. This stresses the CPU and system memory, but the graphics card is idle. This simulates a common scenario during CPU intensive tasks and we believe that Everest's stress test does a good job of stressing the CPU. This test should result in peak CPU temperatures and it was used to measure CPU cooling performance.

The second type of test performed was a real-world gaming test using Call of Duty 4. This test was conducted with all graphical settings set to their highest available levels at a resolution of 1920x1200. Anti-aliasing was set to 4x while anisotropic filtering was set to 16x. Call of Duty 4 is not the most stressful game for hardware currently available (that distinction obviously belongs to Crysis), but we believe it provides a good representation of a fully-stressed system. This test was used to measure GPU cooling performance. The CPU temperatures from this test were not measured, but they were generally below those from the first test.

Temperatures were measured with Everest Ultimate Edition. CPU temperature accuracy was double-checked with Core Temp, which matched perfectly. For all CPU results, the recorded temperature is the hottest of the two cores in the Core 2 Duo E6850 used for testing.

For all tests, the test was allowed to run for 15 minutes at which point Everest begin monitoring temperatures. After another 30 minutes, the average temperature that Everest had recorded over the proceeding 30 minutes was recorded. There was a 30 minute cool-down period between tests where the system sat idle.

All testing was performed 4 consecutive times, over 3 different days at different times of the day. The results of all 4 test iterations were averaged to produce the numbers provided in the graphs. This was done to reduce the effect that slight variances in ambient temperature (which can change throughout the day) had on our test results. Ambient temperature throughout testing was maintained between 21 and 22 degrees Celsius.

It looks like a fairly useful and easy setup... However, i'm not too impressed with the benchmarks (in the review)... I would have thought CPU temps under load would have been significantly lower with this system. It still seems like a good and functional water kit.

I too was hoping to see lower CPU temperatures under load. I wonder how much of a difference the dual fan model with the larger radiator would make? It might be more effective if you were only using it to cool the CPU and it didn't have the additional heat from the GPU. I love the fact that it is a sealed system, and it would appear to be well priced.

Will the CPU block be compatible with the new Nehalem socket motherboards if they offer a new mounting ring for them?

I am not surprised at all.

 

Watercooling + push pins = very poor results.

 

Add a single 120mm rad for CPU and GPU is nothing but fail.

yea gonna have to argee with that. this seem like it gonna be a major problem with sli. it might match the stock cooling for the gpu in sli lol.

[/quote] I agree with that sentiment. A 120mm rad isn't nearly enough for both a high-end CPU and GPU. But the LCLC does come with other rads, including dual-120mm if you're so inclined. The version used in the Blackbird has the dual-120mm rad. From what I can surmise from the original marketing material, the LCLC was originally designed with mATX applications in mind so all-out performance wasn't really what they were trying to do.

Besides, which self-respecting water cooling enthusiast would even consider a kit? Most people probably aren't too concerned with all-out performance at the sacrifice of everything else.

[/quote] A bunch of online stores have it, although a lot of the really big ones don't. I do know that NCIX current has it on both their US and Canadian website. I've shopped at their Canadian site a lot and can vouch that it's a pretty good store. I think Newegg had it at some point but it doesn't seem to be in there system anymore.

well 99% ill agreed with that but i was planing on sff mod build and was hoping to see it would do alittle better then it did. Wanted to use a kit so to lower the chance of damage from movement and less maintance. =)

[/quote] Isn't the LCLC still basically the one of the best solutions? Especially for under $100. With most SFF cases, you have serious vertical clearance issues and unless you mod the case you won't be able to fit in a 120mm wonder-tower heatsink like the Thermalright Ultra-120. Even if you did fit a mega-tower in there, you'd be cripped by the crappy air-flow most of the time (again, unless you mod). The Silverstone NT-06 we used for comparison in the review is actually really popular with the SFF crowd exactly because it happens to be low enough to fit into most SFF cases. On all Silverstone SFF cases, it is probably the best air cooler to use because they are all designed with the PSU positioned right over the CPU socket, so you can throw a NT-06 on your processor and it should meet up nicely with the PSU fan, which would do double-duty as the CPU fan. From what I've seen, it's actually a pretty effective way to do it, although it sort of stresses the PSU, since all that hot air from the CPU is going through it but it shouldn't be an issue if you get a high quality unit. So if you were using a Silverstone SUGO (v1, v2 or v3) or an X-QPack, the LCLC looks like a winner to me. "Desktop" style cases are a different story, but I don't really consider those SFF, since they are often about the size of the standard mid-tower, except on its side.

Dont get me wrong i think LCLC is a great solution. i was planing on moding a Swiftech H20-120 in to a sff case which has been proven possible with the case i had chosen. I seen people posting numbers for there H20-120 that are below LCLC, not sure if they install a better fan or not. i was just hoping that the lclc would do better then H20-120. Sorry if i upset you, wasnt saying the LCLC is a bad product. 

P.s. (not sure if the cpu temp with the LCLC was test with or without the gpu)

[/quote] Hey higgamo, what gave you the idea that I was upset? Just stating my opinion and responding to your comments. No harm, no foul.

CPU test was with GPU connected. Probably would have performed a bunch better if the GPU wasn't connected too. With only a single 120mm fan, you can't really expect killer performance for both CPU and a 8800 at the same time, but if you're going SFF, you don't really have a choice for a bigger heat exchanger. The H20-120 is CPU only, correct? If I remember correctly, the H20-120 looks pretty much the exact same as a CPU-only LCLC config. I think the LCLC still comes in cheaper, unless you can get the H20-120 on sale. But the H20-120 is definitely a lot easier to find in retail. I didn't test the CPU-only LCLC so I can't comment on the performance.

Edit: I changed my signature for you.
higgamo 6 years ago

no biggy wasnt sure if it was if the LCLC was used cpu and gpu at use a the same time ( nice temp for the price). sorry lol just the reply catch me off guard. the price make me tempted to try it out for my self tho. xD

As stated in the article, You would have more than likely seen better results from a fan that pushes more air. Certain "rads" are design for lower air flow and some air design for higher air flow. With out knowing the spacing of the fins on this rad it is hard to say which fan would suite this best. Most rads are designed for high airflow. Another point is the fact that the pump is built into the water block. Pumps produce heat themselves and therefor shouldn't be built intot he waterblock as it will effect temps. I would say "as is" this product would be ideal for the HTPC market. It offers a low noise, low cost effective cooling solution. I say effective because it does the job but not for a enthusiast system. This is def not designed for high overclocking or volt modding. But as stated already those who tend to do that don't buy kits anyway. So I give it a thumbsup for what it is. A low cost, compact, inexpensive adequate cooling solution. there's my .02

the thing on here that confuses me is this OK it's totally sealed right but liquid especially when used in a radiator type systems is going to evaporate or potherwise break down and dissipate over time since it is sealed that will take longer of course but will never the less happen sooner or later so how do you know when your liquid has broken down to the point that it's dangerous for whatever you have it cooling and then  what can you do buy a new one to replace the sealed yet insufficient unit

I am working on two older high-end gaming rigs and they have Asetek LCLC units on them. The one, when I tried removing it, started leaking out all over the place! I, therefore, have attempted to drain out ALL the liquid, to try and "start over" on this particular unit (the other one seems ok, so far, but I'll remove it also, to make sure it's still securely sealed). I'm hoping the liquid wasn't corrosive or electrically conductive, because there was white residue where some had leaked onto the motherboard at some time prior.

Is it possible to "refill" these units (I know they're not designed to be, but...) and does anyone know if the radiators ever break and leak, because the hose fittings seem perfectly tight and non-removable. I can't tell exactly where the liquid was leaking from, but it was definitely coming from somewhere on the radiator.

Jared, I wouldn't want to even try and fix it... too much risk if it breaks again and leaks...


Can't say for sure if the liquid inside is going to cause you any damage... I would hope not since this thing was meant to be used in a computer.


Anyway, I would just go out and get a new self contained liquid cooler, rather than trying to fix this one. There are many on the market these days!
