Introduction
Today I am going to be taking a look at the DWC-A1 Water Cooler from Titan Computers.
In the history of overclocking, water-cooling was sort of the pioneered "new" method
of cooling your CPU. It was a very extreme way to cool down the system, and very risky
to utilize. Today, water cooling units are becoming a mainstream method of system
cooling. Products are being made that are easy to use, easy to install, quiet, and
perform at a much higher standard than that of any standard air cooler. Today, I'm going to
show you just how effective this "mainstream" unit can be.

Packaging

As always, one of the first things we'll take a look at in this review, is the packaging.
Packaging is important, as it is what brings you the peace of mind of knowing that
expensive product will reach your house safely. The packaging for this product was
superb, and probably the best feature of this product.
The box is made of a harder cardboard than usual, and on the inside, it was packed
very nicely with a soft, yet sturdy styrofoam. Everything was organized nicely, with
no tangled cables or wires.
The gear in the box includes some thermal paste, a needleless syringe, P4 mounting
hardware, instructions, and the actual unit itself. Also included is a thermal pad
and some mounting screws.

Construction & Quality
Good idea's deserve credit. This unit is a good idea, but the problem with it is
that it wasn't implemented properly. Take a look.


The radiator fan sucks air from the top of the bay and blows out through the back
of the bay, blowing all that hot air right back into the case. This works if you
don't install anything above this unit, or if you install it in the top bay of the
case and cut a hole in the top of your case so that it can get fresh and cool air.
The water filling area is on the top of the bay device. This means that in order to
add water to the unit, you have to slide it out of the bay about 3 inches or so.


The water lines are about the size of catheter tube. That basically means that there
is practically no water flow. When water cooling, more water equals more heat removal.


The face plate has a beautiful chrome finish look. It's plastic, not chrome, but shiny
like chrome. That's cool and all, but how many times have you seen a case with chrome
face plates? Me either.
Honestly, a lot of people use water cooling to achieve a much more quiet cooling
system. Another problem with this unit is that since it only cools the CPU, you still
have to have case fans, graphics card cooler, and whatever else you might use. That
means that there is no real noise reduction. The fans can be turned down a bit, but
when they are both on high, they hit a whopping 31 decibles, and when they are both
on low, they still hit about 25 - 28 decibles. There isn't much of a difference. It's
not a loud unit, but it does not really eliminate any noise since you would still
require other cooling in the case.
The unit comes prepared to be mounted on an AMD XP motherboard and has the capability
to be mounted on a Pentium 4 motherboard. The problem with this, is that in order to
mount the unit to your P4, you have to remove the motherboard from the case. This is
so that you can install the "X" plate to the rear of the motherboard, which in turn
holds the P4 Heatsink frame (which you must also replace with theirs). The P4 mounting
hardware is very high quality black steel and is very sturdy.
On a positive note, this unit comes readily outfitted with 3 temperature probes. One
comes premounted inside the water reservoir, another in the CPU HSF, and the third
isn't installed anywhere. You can install the third wherever you would like to have
a temperature probe. On the front is a 3 way toggle switch to display the temps on
Red LCD.
Also, this unit comes pre-lapped. That means that you don't have to sit down for an hour with
a ton of sandpaper and put all that elbow grease into lapping the heatsink just to get
an extra degree temperature drop.

Temperature Benchmarks
This is the part that we've all been waiting for... The actual temperatures. I'm a big fan of
Sisoft Sandra, so that's what I'll be using to display the temps. Take a look.
Test Rig:
Abit IT7-Max2 v.2
Pentium 4 Northwood 2.4
Kingston PC3200 512mb
Maxtor 40GB 7200 RPM 8mb Cache
Sound Blaster Audigy 2 Platinum
Radeon 9700 Pro All In Wonder
For this review, I'm going to be running my CPU at 2.71 GHz because that's about the
highest I can get it stable on air cooling.

Air Cooling w/ Stock Cooler: 130 degrees fahrenheit

DWC-A1 Water Cooler: 140.1 degrees fahrenheit

Those results speak for themselves... what can I say.
Well, the stock cooler outperformed the water cooling unit. Honestly, I think this is due to the small
tubing diameter. There just isn't much water flowing through this thing.
Also, I have to add the fact that when I took those benchmarks, I let the computer idle in Windows 2000 for about
25 - 30 minutes. When I ran the test with the water cooler, I had both the system fan and the CPU fan on high.
The temperature was quite high and I didn't want to turn them down due to possible system crash.
ED. Note:
John is a veteran when it comes to water cooling, and currently uses a water cooled dual P3 1.4Ghz system, with watercooled video card as well.
We both had high hopes for this product, and were impressed with it until we actually got down to business and saw that it was a very poor performer.
Since John and I both have a pretty good understanding of common cooling solutions for PCs - from air, to water and pelts - we tried every idea we could come up with to get this unit to perform better. Perhaps we were missing a detail, or something was amis. But to no avail... This watercooler is simply a very poor cooling solution, unfortunately. Good concept - poor implementation.

Conclusion
There are a few good points and some bad points about this device. It has an
excellent concept, and if were developed a little better, it would be a superb
device. My suggestions for modification to this device are: Make the exhaust fan
blow out the front so that all the hot air is not blown back inside the case.
Also, make the water lines larger. More water flowing through those tubes would
greatly increase the amount of heat that was removed from the CPU. Next, the
refill hole is in a bad spot. I don't really know of a better place for it, but
where it's at requires you to remove the unit from the case to fill it.
As far as cooling is concerned, I'd go with something different if you would
like to overclock. If you aren't overclocking very far, or would like something
new, this device might be alright. For those of you who don't overclock, this just
might be your ticket to get your foot in the front door of watercooling.
In light of the above statements and my thoughts of this product, I would like
to award this watercooling device 2 of 5 X's.
