Testing Configuration and Benchmarks Used
To verify that the cooler kit operates up to specs, the EXT-440CU Liquid Cooling unit and the CPU-380I water block were tested with the CPU running in both stock and at a known stable overclocking speed using both Z77-based and Z87-based motherboards, so that comparative results could be provided for both Ivy Bridge and Haswell-based systems. The results are presented for the cooling kit under review as well as the XSPC Raystorm 750 EX240 water cooling kit, Corsair H100i water cooler, and the Thermalright SilverArrow SB-E air cooler for performance comparison purposes. The benchmark tests used should give you a good understanding of the Koolance kit's capabilities so that you, the reader, can make a more informed purchasing decision. The comparison coolers were selected based on their superior performance capabilities.

The 64-bit Windows 7 based test bench used for LGA1155 board testing includes an Intel Core i5-3570K CPU, 8GB of DDR3-2133 memory, an AMD Radeon 5870 1GB video card, and an Intel 520 240GB SSD drive. Using the selected components gives us the ability to demonstrate the cooling system's capabilities rather than that of the system components.
The 64-bit Windows 7 based test bench used for Intel Z87 LGA1150 board testing includes an Intel Core i5-4770K CPU, 16GB of DDR3-1866 memory, an NVIDIA GTX 570 1.25GB video card, and a Samsung 840 EVO 250GB SSD drive. Using the selected components gives us the ability to demonstrate the cooling system's capabilities rather than that of the system components.

A SILVER AWARD?????
For $235
A SILVER AWARD?????
For $235 (with out tax) i got a set that easily outperforms this set.

Can be build in a case, and just looks better, because in the end, one of the most important parts the radiator is just way to small.
And spend the same amount as this set cost, then you have something real nice.

… your link in in €* … that’s a euro.. not a dollar, euros are worth more.
I believe the US shows prices
I believe the US shows prices without tax, so I did the math.
€215 – 19% tax = €175 = $235
Was the block mounted
Was the block mounted perpendicular to the memory slots? This is the optimal config for the 380i, matters by 1.5 degrees. I have the 380i block in my loop.
The radiator isn’t too small,
The radiator isn’t too small, Koolance has been making good watercooling gear for along time. As for mounting the block perpendicular to the RAM, that is dependent on the motherboard chipset and if the motherboard is even a reference design. Chances are, the only reason someone has seen a difference is that at a certain angle the hoses were putting pressure on the mounting and screwing with the thermal joint between the waterblock and the processor.
I think it should be
I think it should be emphasized that the water kits being compared (XSPC EX240 and Corsair H100i) are both dual-fan radiators. EXT-440CU is just a single-fan radiator unit. Koolance’s dual-fan rad external unit is EX2-755.
Yes, I think anybody that
Yes, I think anybody that would go this route (external unit) would go for 240mm model .
Little OT but may I ask why the 4400 OC is done with a 42x by 105 blk , instead of straight 44x by 100blk . Is it is easier voltage wise for 42x@105mhz ?
Those specs were used for the
Those specs were used for the Z77 board because they were there stable o/c specs from when the board was originally reviewed. Using a 105MHz base clock atually puts the system under a little more stress than with a 100MHz base clock, requiring more voltage to stabilize..
Also Should of reviewed the
Also Should of reviewed the Ex2-755 V2 as its almost same price ( $285) . Which is 240mm and probably look good on top of case if it has flat top .
