Today we are testing CoolIT ECO liquid cooling system, a compact sealed system where all you have to do is to install the cooling block on your CPU and attach the radiator to your case. Will it perform better than air coolers we tested so far? Check it out!
In a classic watercooler, you must buy separated parts, assemble the system, connect the hoses, prepare the liquid, fill the system, etc. A sealed system comes prefilled and preassembled, which simplifies the installation, as you won’t have to handle hoses, liquids, connectors, pumps, etc.
ECO box is simple, in white cardboard paper. The cooler comes nicely accomodated in a foam inner box.
Inside the box we found the preassembled system (ready to install on Intel CPUs), user manual, AMD clips and three backplates, one for each Intel socket.
In the next pages we will see this cooler in detail.[nextpage title=”CoolIT ECO”]
In Figure 3, you can see the block (piece that is installed on the CPU that transfers the heat from it to the liquid inside the system), which has an integrated pump. This pump has a three-pin power connector that must be connected to the motherboard.
Figure 3: Block with integrated pump.
In Figure 4, you can see the base of the block, made of copper. The finishing could be better, since it is flat but hasn’t a mirror-like surface. The preinstalled adjustable clip fits sockets 775, 1156 and 1366 CPUs.
In Figure 5, you can see the radiator (component that transfers heat from the cooling liquid to the air), which comes with a preinstalled 120 mm fan. This fan has a miniature four-pin power connector, which means it has automatic PWM speed control.

In Figure 6 we have a front view of the radiator. It allows the installation of a second (not included) fan.
In Figure 9, you can see the 120 mm black fan that comes installed on the radiator.

Installing ECO is as simple as the installation of most air coolers. You just need to put the appropriate backplate on the solder side of the motherboard, put the block on the CPU and fasten the four thumbscrews. Unfortunately, CoolIT ECO didn’t come with any thermal compound. During our benchmarking we used Zalman ZM-STG2 thermal paste. In Figure 8, you can see the block installed on our motherboard.
Figure 8: Block installed on the motheboard.
After installing the block, you just have to put the motherboard back to the case and then attach the radiator and its fan on the rear part of the case. Note that this is a very simple task if your case has a space for a 120 mm fan on its rear panel, but if it doesn’t you can’t install it properly. In our test system the radiator was touching the block, but we could see it was not forcing the block.
[nextpage title=”How We Tested”]
We are adopting the following methodology for our CPU cooler reviews.
First, we chose the CPU with the highest TDP (Thermal Design Power) we had available, a Core 2 Extreme QX6850, which has a 130 W TDP. The choice for a CPU with a high TDP is obvious. To measure the efficiency of the tested cooler, we need a processor that gets very hot. This CPU works by default at 3.0 GHz, but we overclocked it to 3.33 GHz, in order to heat it as much as possible.
We took noise and temperature measurements with the CPU idle and under full load. In order to achieve 100% CPU load on the four processing cores we ran Prime95 with the "In-place Large FFTs" option, and three instances of the StressCPU program, all at the same time.
We also compared the reviewed cooler to the Intel stock cooler (with copper base), which comes with the processor we used, and also with some other coolers we have tested using the same methodology.
Temperature measurements were taken with a digital thermometer, with the sensor touching the base of the cooler, and also with the core temperature reading (given by the CPU thermal sensor) from the from the SpeedFan program, using an arithmetic average of the four core temperature readings.
The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed 4" (10 cm) from the fan. We turned off the video board cooler so it wouldn’t interfere with the results, but this measurement is only for comparative purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.

On the tables below you can see our results. We ran the same tests with the coolers shown on below tables. Each test ran with the CPU idle and then with the CPU fully loaded. On BigTyp 14Pro, TMG IA1, NH-U12P and ISGC-300 the tests were done with the fan at full speed and at minimum speed. The other coolers were connected directly to the motherboard and it controls the fan speed based on CPU load level and temperature on PWM models. ISGC-400, iCEAGE Prima Boss, Megahalems Rev. B, Thermaltake SpinQ VT, Zalman CNPS10X Flex, Tuniq Tower 120 Extreme and Tuniq Propeller 120 were tested at minimum speed on idle test and at maximum speed on full load test.

[nextpage title=”Conclusions”]
The point in using a liquid cooling system instead of an air cooler is to obtain better performance with less noise. With this in mind, CoolIT ECO failed, because it achieved an average performance, even compared to the air coolers we tested so far.
Regarding noise level, the pump is very quiet (actually, inaudible), but the fan even though it was very silent when our CPU was idle was relatively loud with the CPU fully loaded, with a noise level equivalent to the one achieved by good air coolers.
ECO is a little bit more expensive than most high-performance air coolers. Therefore the only reason someone would buy ECO would be to impress his or her nerd friends, without any real performance advantages or cost/benefit ratio in mind.
