Cooler Review : CoolIT Domino & Freezone Elite

coolit.jpg


When building a pc one of the main concerns is the heat output from the components and the best way to exhaust the heat from the system. This is a particular issue when dealing with high end components and with the release of the Intel Core i7 Processor we have seen temperatures soar to new heights, CoolIT have released two products here that aim to combat the heat issues at hand with the latest release of CPUs.

All system builders / system integrators are looking for new ways to cool their systems to give the best performance, stability and noise levels. To obtain the best performance and noise levels a increasing number of individuals have started to use liquid cooling as ways to keep the noise and temperatures down when cooling high end components. CoolIT have realised that there is a lack of self contained low maintenance coolers on the market to deal with the increasing heat load with the latest CPUs.

There has been liquid cooling “kits” on the market for some time now comprising of individual components which the user must assemble and maintain. While these kits offer the performance needed the expertise needed to install and maintain such a system has often deterred users from buying such a product. This is where the CoolIT Systems come into the market. CoolIT pride themselves on producing self-contained liquid cooling solutions for a wide range of applications such as Gaming Machines to Servers. There is a wide range of users that want the best performance from their machines but don’t want to risk the components by installing a custom liquid cooling kit.

In this review i will look at the CoolIT Domino Advanced Liquid Cooler (A.L.C), the CoolIT Freezone Elite and a Custom Liquid Cooling solution and compare the results and costs involved.

Testing Methodology.

To best demonstrate the capabilities of the three solutions I will use the latest Intel Core i7 Processor both at Factory settings of 2.67GHz @1.2v and Overclocked to 3.6GHz @ 1.3v.

All cooler will be subject to an idle test which will display the lowest temperature that the cooler is capable of. The computer will be left for 30 minutes at the desktop with only temperature monitoring programs running and the lowest temperature after this time will be noted.
As the Domino is capable of 3 modes of operation (Quiet, Balanced and Performance) each Idle test will be ran 3 times using the 3 different modes to give results for all possible situations.

The Freezone Elite used in conjunction with the MTEC Control Centre is programmable to achieve different results using different fan speed and T.E.C usage. To achieve the best results I have decided to test at Fan Speeds and T.E.C Usage of 50%, 75% and 100%.

The Custom Liquid Cooling solution is controllable also using the T-Balancer software which controls fan speed. I will use the same 50%, 75% and 100% Fan speed for the Custom setup to achieve similar Results as the CoolIT solutions.
Test Setup.

Power Supply – Silverstone ST-1000 - 1000W Modular Power Supply
Motherboard - MSI X58M – Micro ATX X58 Motherboard
Processor – Intel Core i7 920 D0 Stepping @ 2.67GHz & 3.61GHz
Memory – 6GB Corsair Dominator 1600 MHz
Graphics – ATI HD4870X2
Hard Drive - Samsung 1TB 103UJ
 
Installation.

CoolIT Domino A.L.C.


The CoolIT Domino requires a 120mm fan space at the rear of the case to be installed. When installing the Domino a backplate is needed on the rear of the motherboard to secure the cooling block to the CPU. Once the backplate is installed it is as simple as screwing 4 screws into the motherboard backplate to secure the CPU block into place and then attaching the radiator unit to the rear of the case using the supplier rubber grommets.

As the Domino is powered from a 3pin fan connection, after connecting this to the motherboard the pc is ready to be powered up. The installation of the Domino was fast and as easy as installing a conventional CPU cooler.

CoolIT Freezone Elite

The same applies to the Freezone Elite as to the Domino, it also only requires a 120mm fan space at the rear of the case for installation, if anything installing the Freezone Elite was easier than the domino as the tubing going to the CPU block was longer allowing easier installation.
The same backplate was needed for the Freezone Elite after installing this it was a case of screwing the 4 screws into the backplate to secure the CPU Block.

As the Freezone Elite is bigger and heavier than the Domino it requires 4 large screws into the rear of the case to secure the unit into place.

Test Results

All results were taken using Hardware Monitor after 30 minutes of each test. Idle results are taken with the CPU running no tasks at the Desktop after 30 minutes of the PC being turned on.

Load temperatures were taken after 30 minutes of Prime 95 running Small FFTs on all Cores on the CPU.

The following results are taken with the CPU @ the stock setting of 2.67GHz @ 1.2v

To show how cost effective each cooler is the following results are calculated from the temperatures taken using the overclocked settings.

As you can see from the above bars the Freezone Elite proves to be a great value sealed unit as it’s easy to install and provides good results when using 70% or more fan speed.

Conclusion

All 3 solutions cooled the CPU to temperatures below the Thermal Junction when overclocked which leaves the other factors to consider.

When taking into account the required skill, case needed and time taken to install the 3 solutions and the resulting temperatures if I were to chose a solution I would have to say that the Freezone Elite would get my vote. As the Freezone Elite would fit into most midi or bigger tower cases without modification this makes the Freezone Elite the most powerful cooling solution for most situations. As the custom solution requires a full tower with extensive modification the target market for this type of cooling is very small.

When using the 75% or higher settings on the Freezone Elite the temperatures achieved from the size of the unit are excellent.

Thank you all for reading.

How were the results standardized? Specifically is 50% quiet the fans at 6V instead of 12V, at 50% maximum rpm, or at a set dB count? Are the same fans used in each case, I see that seven (?) 2100rpm yate loons are used on the quad but not what were used on the coolit.

I'm struggling a little to interpret your results. Cooling performance is closely linked to radiator surface area, so the only way the coolit systems can match a quad radiator is if the quad was completely over-specified. A comparison against a 240 or perhaps even a 120 radiator would be more illuminating, and rather change the cost vs performance graphs. Similarly not using 7 fans on the quad would make a difference here.

The review is well written and quite thorough, my only issues are with standardizing for noise and that the water cooling loop was inappropriate for the hardware. Thank you for posting it.

p.s. Sealed unit is a negative rather than a positive, as when it inevitably requires maintenance, you can't give it any :)

i sed 50% 75% and 100% as equivilents to the quiet/balanced/performance modes on the domino.

the control centre software of the Freezone elite allows you to set fan & Tec % so set at 50, 75 and 100. the same was set for the FOUR fans on my quad rad using the t-balancer which also allows to set % of fan speed.

the extra 2 front intakes were kept at a standard speed depending on the ambient temperature using the t-balancer. and in the case of the coolit coolers the rear fan was replaced with the coolit units so wasnt used. when it was used with my qiad testing it was also kept at a speed related to ambient temperatures to keep the test fair.
