Silverstone, known mainly for their cases, recently impressed us with the Argon
AR01 and AR03 heatsinks, which utilized direct-touch heatpipe technology.
The AR03 was particularly noteworthy given its performance relative to price
and size. The Argon line can be most succinctly described as “efficient”.
SilverStone’s latest push into CPU cooling takes an entirely different approach.
The Tundra series is comprised of a pair of premium all-in-one liquid coolers,
the dual radiator TD02, and the more modest single radiator TD03 which we’re
looking at today.
The products of this genre offer an easy introduction to water cooling for
those unwilling to put the time, energy, and money, into setting up a “proper”
cooling loop, typically a mix of compatible components similar to how a custom
PC is assembled. A structure containing a water block and a pump is mounted
to the CPU. Heat is transferred to the coolant inside and pumped through one
tube to a radiator installed on a 120 mm fan placement. The heat is then spread
through the radiator via a series of pipes and coils/fins, and the heated transferred
into the air, which is then exhausted out of the case by a fan. The now cooled
liquid flows through the second hose back to the water block, completing the
cycle. It’s similar to the way a heatsink with heatpipes works, but spread out
over a larger area with a pump actively creating flow rather than relying on
conduction.
While it sounds great in theory, the self-contained water CPU cooler units
we’ve tested have been disappointing. Compared to a typical air-cooled heatsink,
they are louder because the pump is as an additional noise source, and the included
fans are usually high speed models. Performance is usually average at best,
installation is often more difficult or tedious, and the cost ranges from high
to extravagant. Most models are based on designs by or manufactured directly
by the same company, Asetek. These Asetek coolers/clones have an almost uniform
style/appearance. The Tundra breaks the mold, having several distinct design
aspects that might give it an edge over the masses.

|
Rather than using thin, tightly spaced coils, the bulk of the radiator’s cooling
surface is composed of heatsink-like fins. While this makes the heat dissipation
area smaller, the impedance to airflow appears reduced, making it easier for
a fan to blow through. The base is thicker and better built with a full metal
body encapsulating the pump. Mounting arms are incorporated into the structure,
sitting above the water block so a tighter, more secure mounting system can
be employed.

Opening the box reveals a tray similar to a paper egg carton, with compartments for the various components. Included in the package is the cooler itself, a pair of 120 mm fans, a dual fan cable, the necessary mounting hardware, and a brief installation guide.

PHYSICAL DETAILS
The SilverStone Tundra TD03 is composed of a 15.2 x 12.4 x 4.4
cm radiator with a plastic outer shell and nickel-plated aluminum fins, a pair
of 8 mm thick, 30 cm long, stiff plastic hoses connected to a 33 mm tall rectangular
structure containing the pump and a copper water block. Without the fans, the
entire structure weighs a total of 780 g, though only a small portion of this
mass sites atop the CPU.

BASE & INSTALLATION
The most critical aspect of installation is that the cooler be securely
mounted. A firm mating results in good contact between the unit’s base and
the CPU heatspreader and more efficient heat conduction. Ideally it should
also be a simple procedure with the user having to handle as few pieces of
hardware as possible. For the Tundra series, SilverStone uses a simple bolt-thru system that most enthusiasts have probably seen in some shape or form previously.

Measurement and Analysis Tools
- Extech 380803 AC power analyzer / data logger for measuring AC system
power. - Custom-built, four-channel variable DC power supply, used to regulate
the fan speed during the test. - PC-based spectrum analyzer:
SpectraPlus with ACO Pacific mic and M-Audio digital
audio interfaces. - Anechoic chamber
with ambient level of 11 dBA or lower - Various other tools for testing fans, as documented in our
standard fan testing methodology. - SpeedFan,
used to monitor the on-chip thermal sensors. The sensors are not calibrated,
so results are not universally applicable. The hottest core reading is used. - Prime95,
used to stress the CPU heavily, generating more heat than most real applications.
All instances are used to ensure full stress. - CPU-Z,used to monitor the CPU speed to determine when overheating occurs.
- Thermometers to measure the air temperature around the test platform
and near the intake of the heatsink fan.
Noise measurements are made with the fans powered from the lab’s variable DC
power supply while the rest of the system was off to ensure that system noise
did not skew the measurements.
Load testing was accomplished using Prime95 to stress the processor, and the
graph function in SpeedFan was used to ensure that the load temperature is stable
for at least ten minutes. The temperature recorded is the highest single core
reading. The stock fans were tested at various voltages to represent a good
cross-section of airflow and noise performance.
The ambient conditions during testing were 10~11 dBA and 21~23°C.

Additional notes: |
The TD03’s stock fan has the same model number as the Argon AR01/AR03’s 2200
RPM blower, but with a nominal rotational speed of 2500 RPM, it’s a slightly
more powerful variant. The structure is the same, with wavelike teeth and ridges
cut into the blades on the exhaust side.

ASUS Fan Xpert 2 utility, or more specifically, its fan auto-tuning feature,
gives us an idea of what to expect in terms of usable speeds when using onboard
fan control. On PWM, the lower limit is about 1300 RPM, while on voltage control,
it can run as low as 800 RPM before it stops spinning altogether.

Measuring mic positioned 1m at diagonal angle from the center of the cooler base. Ambient noise level: 10~11 dBA. |
The stock fan is very noisy, generating an earsplitting 36 dBA@1m at full speed
and only becomes quiet when brought down to the very low end of its range. It
enters the quiet zone at about 1200 RPM. Being a water cooling system, the TD03
has a second source of noise: The pump. Since our first all-in-one liquid cooler
review three years ago, pumps have become noticeably quieter and the TD03’s
is no exception. At full speed it produces only 17 dBA@1m and with a bit of
undervolting, becomes muted very quickly.
|
While the pump is fairly quiet by water cooler standards, the quality
of the noise is bad, especially at full tilt. At 7V and 9V, it emits a harsh
buzzing like a fly hovering next to your head. At full speed the pitch increases
considerably making it more annoying. The fan, for the most part, has a similar
acoustic character to the Argon AR01/AR03 stock fan. It is relatively buzzy
at higher speeds but the noise is more broadband and less tonal, while at lower
speeds it tends to drone and hum slightly.
Combined Noise Measurements | ||
Pump Voltage | Fan Voltage | SPL@1m |
12V | 12V | 36 dBA |
9V | 30~31 dBA | |
7V | 25 dBA | |
6V | 22 dBA | |
5V | 18~19 dBA | |
9V | 6V | 21~22 dBA |
5V | 18 dBA | |
7V | 6V | 21 dBA |
5V | 17 dBA | |
Measuring mic positioned 1m at diagonal angle from the center of the cooler base. Ambient noise level: 10~11 dBA. |
The combined noise output is very similar to the fan on its own. The pump’s contribution is only audible when the fan is running at 6V and below, and even then, the difference is minuscule. If the fan is spinning at a decent speed it doesn’t make any sense to slow down the pump at all.

With the stock fan, the Tundra TD03 is an excellent CPU cooler, but only at
high fan speeds. At lower fan speeds, its cooling proficiency dropped to middling
range. Equipping the second fan netted about a 3°C drop across the board
but the increase in noise meant that no overall gains were obtained; ie, a given
noise level provided the same cooling as with one fan. We also found that slowing
down the pump had hardly any effect.
Our reference Nexus 120 mm fan delivered better results despite not being designed
specifically for this type of cooler. However, it is not entirely surprising
given the nonstandard structure of the radiator that is somewhat similar to
an air-cooled heatsink. Once again, we found that adjusting the pump voltage
accounted for only a minute performance difference, but the Nexus’ lower noise
levels were obviously preferable.
The Nexus fan’s superior acoustics also gave it an edge in dual fan performance.
The addition of a second fan was a net positive, especially when both the pump
and fans were set to 7V. In this configuration, we observed a 6°C improvement
compared to the single reference fan setup.

The TD03’s best results aren’t terribly impressive. With a single stock fan, it’s in line with the Antec Kühler H20 620, and with dual stock fans it is similar to the larger H20 920. Compared to the multitude of air coolers we’ve reviewed, it’s positioned near the middle along with the other water cooling units. Using our reference fan bumps up its station up considerably but for US$100, plus the cost of the replacement fans, it’s not a very cost-effective choice.

*Note: there are minor differences in measured SPL due to the variety of fan orientations and mounting methods offered by the compared coolers. |
Against competing air coolers armed with the same 120 mm reference fan, the TD03 takes a back seat to a whole host of heatsinks. It’s not a bad cooler per se, but keep in mind every single product on this list that placed above it is cheaper, some by half or more.
MP3 SOUND RECORDINGS
These recordings were made with a high
resolution, lab quality, digital recording system inside SPCR’s
own 11 dBA ambient anechoic chamber, then converted to LAME 128kbps
encoded MP3s. We’ve listened long and hard to ensure there is no audible degradation
from the original WAV files to these MP3s. They represent a quick snapshot of
what we heard during the review.
These recordings are intended to give you an idea of how the product sounds
in actual use — one meter is a reasonable typical distance between a computer
or computer component and your ear. The recording contains stretches of ambient
noise that you can use to judge the relative loudness of the subject. Be aware
that very quiet subjects may not be audible — if we couldn’t hear it from
one meter, chances are we couldn’t record it either!
The recording starts with 5 second segments of room ambiance, then the fan
at various levels. For the most realistic results, set the volume so that
the starting ambient level is just barely audible, then don’t change the volume
setting again

FINAL THOUGHTS
The all-in-one water cooler SilverStone Tundra TD03 uses a different design
than its multitude of competitors. Its radiator utilizes thick, heatsink-like
fins rather than the traditional long and thin coils, and the pump exterior
is a sturdy metal box instead of a round encircled with plastic. The mounting
system is also more secure and less fidgety to install than those preceding
it. Unfortunately, despite all these differences, the result is nothing revolutionary
or even evolutionary. Out of the box, the TD03’s overall performance:noise ratio
is very close to previously tested liquid coolers, that is to say, middling
at best compared to most large air-cooled heatsinks.
Furthermore, like most such devices, the TD03 doesn’t boast great acoustics.
The included fans are too high in speed, requiring a tremendous amount of undervolting
to bring them down to quiet levels, and on PWM control, it might not possible
at all depending on your personal standards. The pump also generates an unpleasant
buzzing, though it is relatively quiet as pumps go and gets drowned out by the
stock fan(s) at all but the lowest of speeds.
Typically, water coolers are paired with special fans designed specifically
for high static pressure to match the dense structure of old school radiator
designs. The TD03’s stock fan is essentially the same as the larger versions
of SilverStone’s Argon heatsink series but this choice makes sense in theory
given the radiator’s unusual construction. In practice, it was surprisingly
inferior to our reference Nexus 120 mm fans which previously had failed to impress
when paired with similar coolers.
With our reference fan, the TD03 became a fairly decent cooling solution, but purchasing aftermarket fans adds even more cost to the TD03’s already high US$100 street price. Even if the stock fans performed equally, you could still buy two or three comparable air-cooled heatsinks for the same money, such as SilverStone’s own AR01 and AR03. On top of that, the TD03 occupies a 120 mm case fan mount which could otherwise be used to further complement CPU and overall case cooling. The Tundra TD03 is the best constructed water cooler we’ve seen, but like its contemporaries, it has little to offer aside from the novelty of having liquid coursing through your PC.
