Testing:
Leak testing of 12 hours is usually the advised method. Since time is of the
essence, I opted to let it run for 2 hours while checking the connections and
wiggling the tubing to see any unforeseen leaks. Once convinced the system was
leak proof, the motherboard was then carefully put back in the case. Since all
the wires and components were completely taken out, there was little resistance
or difficulty getting the motherboard in place. All the power and components
were reconnected to the motherboard which leaves us with some testing.

No Leaks! Let's Test It. |
Test Notes: Room and distilled
water temperatures were kept to 75 degrees Fahrenheit. Additives were not added
due to the short use of the water cooling system and to eliminate any possible
performance hindrances.

First, we should get the obvious
out of the way. The temperatures foremost speak for themselves and the quality of the
components. We've seen water blocks that didn't have the most mirror like
bottoms affectively cool processors within a couple degrees but couldn't
maintain a low temperature under heavy load. Water temps were also very slow to
rise with the EHX. Still, these temps are among some of the best to come across
the test system.
The CPU cooler does a great job of keeping the processor very cool, especially
in its over clocked frequency. What helps this is the size of the GPU-300-V10
and its dispersion surface. The base covers the entire processor fully and
tapers out to gain another near 1/2 inch of internal surface and receives the
bulk of the 10mm tubing's water flow.
Video cards will continue to have the hottest processors as long as the
processor makers keep their thermal properties in check in the next few years.
Smaller graphics processors would help keep the heat low, but we aren't going to
see these for some time. The GPU-180-L06 and V06 uses a smaller tubing diameter
which means it is able to cool the GPU and Nvidia chipset cool using less water.
Both the L06 and V06 do a very good handling rising temperatures. Overclocking
maxed out at the very same settings as any other VGA block mainly due to the
fact that the 7800 GT comes factory overclocked.
Working with the RP-1000 was actually pretty cool. With each press of the <SET>
button, it would report each water block's temperature and within one degree of
the AbitEQ software. Naturally, the water block sensors are more accurate as
Windows isn't guaranteed to report and work correctly with the onboard thermal
sensors. Pressing <SET> four times would cycle through each temperature sensor:
Sensor 3-CPU, Sensor 2-Chipset, Sensor 1-VGA. With each press of the arrows the
fans would speed up or slow down and if this is too much control, AUTO will
adjust the fans to match any of the 10 modes you select.

And then there is the blue LEDs inside the reservoir and face of the RP-1000
that adds a bit of light to the entire system. The LEDs are bright and clear
which makes them very easy to see. The red number is the block sensor which
corresponds with the temperature displayed. For example, these particular
pictures show sensor 3 which is the CPU. When the RP-1000 was pushed back in on the
Coolermaster Mystique which already had a blue LED 12cm inside, it made
the entire front bezel glow which was very cool.

This brings us to the fans and noise. On highest setting, the fans were very
audible and throwing out about 40db. At the lowest setting, the fans were nearly
inaudible and also much nicer to work around. Temperatures are affected by a
couple degrees at most and would really only benefit a system in a very hot
area, or perhaps a system going for some over clocking record. Low or Medium fan
speeds will perform perfectly fine and with good results.

Summary:
And
Koolance said, let there be
EHX
1050SL Water
Cooling and it was good. What you get is a high quality product designed to
work with any system whether its an internet only computer or an extreme gaming
system. From the water blocks to the screws, this is one extremely detailed
water cooling kit that utilizes the new RP-1000 Reservoir and Pump unit to give
the user manual or automatic control of their system.
It looks great in just
about any installed configuration conceived for every possible use. The EHX
should easily please the most avid user demanding results from their kit. We'd
like to extend a big Thank You to Koolance for providing the EHX 1K giving us a opportunity to
experience the gold side of water cooling.
