At
this point I'd fired up the pump but not the fan, and this is
where my enthusiasm was dampened somewhat. I'd set the system
up (after some basic pipe work measurement in the system) outside
of the case, as I wanted to make sure there was no leaks before
I put it anywhere near my computer. I grabbed an old 200watt PSU
and connected the fan up. The fan kicked in and
.. Oh no.
The fan is loud, louder than my Air coolers. Were not talking
Delta screamers or anything but according to the YS-Tech specs,
it's at 40.5dB. That is by no stretch of the imagination quiet,
which when it comes to watercooling, I was always lead to believe
was one of the big plusses. That said, the specs also stated the
fan was rated to run at 7-16 Volts. Whipping out my trusty needle
nose pliers I swapped the ground lead over to the +5 volts, and
dropped the fans running voltage from 12 volts to 7 volts (for
more information on this see
here). This made the fan run at just over half speed which
is completely silent but would it be enough to keep the system
cool?

Testing
The
test system is as follows :-
Athlon
Thunderbird 1.4
Abit AT7 Max
Windows XP (Sp 1)
GeForce 4 Ti4600
The
Air coolers I'm comparing with are :-
AKASA
Silver Mountain 2Q
Swiftech MCX462 with Coolermaster 3000 RPM 80mm FAN
I've
tested the watercooling kit under both 12 volt and 7 volt operation,
as although this isn't the way it is supplied, it is something
that some users will want results on considering the noise generated
at 12 volts. For idle settings, Windows was booted up and left
for 15 minutes and a reading taken. For load settings Quake III
Arena was left running a looped Timedemo for an hour and readings
taken. This was done 3 times and the average temperature taken
for each. Room temperature was maintained at 26C. In the case
of the aircooling, the side of the case was left of because as
I have stated before, my case really is a poor performer when
it comes to heat. To keep things equal the side of the case was
left off during testing of the watercooling kit, although the
entire kit was placed inside the tower.

You
can see in the graph here that even with aircooling this 1.4 is
a hot runner. In defence of the air coolers they are pretty quiet
but they are still the loudest items in my system. The Watercooling
kit however really does perform well, with temperatures at load
rarely reaching the idle of the aircoolers. Running the fan at
12 volts is quite loud and as you can see even running the fan
at 7 volts the temperatures are very good for such a hot running
chip. So what about overclocking? Overclocking with the aircoolers
raises the temperatures above by 2C across the board on both with
an increase in the voltage from 1.75v to 1.85v. With the watercooling
kit the temperature remains the same as at stock speeds and voltages.
For the first time I was able to reach 1540Mhz. I had always suspected
that this CPU's ceiling was 1533, and whilst were only talking
a 7Mhz increase here, the fact that it allowed me to run higher
than ever before should not be dismissed. And in total silence.
There wasn't a difference in running the fan at 12 volts or 7
volts to the overclocking results, but considering the noise factor
I know which one I will be running from now on :) All in all a
great performance from the watercooling kit.
Final
Words

This
is a great kit at a great price (£143). The kit includes
everything you need to get running except the water, and with
push fittings throughout it couldn't be easier to setup. It literally
takes just a few minutes to have the kit up and running and the
results are fantastic, with drops in temperature of 6C compared
to aircooling. The kit does have a few little flaws, such as the
instructions; it would have just been nice to have more of a visual
aid to go with the simple text. The lack of clips for the pipe
work is not a flaw however as they are not needed at all. The
push fittings ensure that everything is water tight and leak free.
There
was really only one real let down and that was the included fan.
Watercooling has always appealed to me as much for its noise levels
as its performance, and the included 120mm fan is not quiet at
all. The fan is rated to run at 7 volts (which is how I'm running
it) but this isn't how the kit was shipped or intended for use.
Running it at 7 volts doesn't increase the temperatures by a big
amount, no more than 2C, and reduces the fans noise output to
complete silence. Perhaps some sort of fan speed device could
be included with the kit? Visually, the kit is stunning with a
simple and clean aesthetic throughout and it's nice to see thought
has gone into this area of design as well as the performance of
the kit. Ease of use is a theme throughout, from the push fitting
connectors for the pipe work to the wind up screw on the waterblock
clip. The fact that this is a watercooling kit only and not enclosed
in a case of some kind makes it very versatile, with nothing stopping
you moving it from system to system as and when you upgrade.
I'm
really torn at this point as to whether or not to give the kit
an Editor's Choice award. Considering the price, ease of use and
performance, it is certainly deserved of one, but that noisy fan
is bugging the hell out of me. There's nothing to stop you changing
the fan or reducing its speed but this is not how the kit arrives.
If you are looking to get into watercooling for the first time
this is the kit to get, for the price you will be hard pushed
to find similiar at the same quality. If you're a watercooling
junkie, you might do better to look at the components on an individual
basis. All of the components in this kit are available separately,
and there is also a waterblock designed for the P4 (basically
the same with just a different clip, though still as good looking).
With the exception of the fan, I'm personally very pleased and
impressed with the entire kit. Big thanks to the guys over at
Wet and Chilly Chips
for supplying the review kit.
Pro's
The performance is great
It really does look drop dead gorgeous
Easy to set it up
Versatility, you're not tied down to one case
The coolness factor when showing off to your friends
Con's
Fan is quite loud
Instructions, whilst easy to follow, could do with some visual
aids
Bottom
Line
This is a really good looking and well performing complete kit
at a great price. The fan is quite noisy, so if silence is something
your looking for, be prepared for some extra wiring work or cash
spent on a new fan/fan speed control device.
