Thermaltake BigTyp 14Pro: A Bigger Typhoon

The Thermaltake’s BigTyp 14Pro, as its name suggests is a bigger version of the Big Typhoon, sporting longer heatpipes and a 14cm fan. The Big Typhoon at the time of its release was one of the larger heatsinks one could buy, but by modern standards it is rather quaint. Can this updated titan compete with the big boys of today?

Thermaltake’s BigTyp 14Pro is, as its name suggests, an even bigger version
of their Big Typhoon. At
the time of its release, the Big Typhoon was one of the largest heatsinks one
could buy. By 2009 standards it is “Big” no longer — enthusiasts
have seen much larger CPU coolers come and go. So, naturally, Thermaltake had
to make it bigger.

While many of Thermaltake’s products have unique design elements that show
off their creative, outside-the-box thinking, the BigTyp is a result of a more
traditional brute force strategy. It is basically a wider Big
Typhoon VX
with a larger 14cm fan, longer heatpipes, and a more secure mounting
system to deal with all the extra weight.

Feature & Brief
Our Comment
Strong Cooling Structure
– with mirror coating copper base, 6 copper heatpipes, supports up to TDP
With 6 copper heatpipes it better be
able to handle a 130W CPU.
14cm Giant Fan with Blue LED
– the downward flow big fan covers more area to help system cooling not
only for CPU
Generally the bigger the fan, the more
efficient it is.
VR™ Fan Function
– allows you to adjust the fan speed for your need
Most of Thermaltake’s coolers have a
manual fan speed controller included.
Completely Silent
– 14cm fan could make good cooling effect at only low fan speed and generate
minimum noise at the same moment
If all their heatsinks are silent we
wonder what they consider to be loud…
Universal Clip
– for the mainstream PC platforms such as LGA775 and AM2 sockets
That’s strange … if it’s universal,
why include separate mounting systems for LGA775 and AM2?

The BigTyp is similar in appearance to the Scythe
, another large top-down cooler with a 140mm fan. In design, it is
much closer to its predecessors, the Big Typhoon and Big Typhoon VX.

With the fan removed, the heatsink body is revealed to be have the same
basic build as its predecessors. The heatpipes are very long, going from
one half of the heatsink body to the base, out the other side and then
extending into the second half. Our sample had patches of odd discoloration

on each heatpipe.


The BigTyp’s 140mm fan has an open-air design without a traditional casing.
Its support struts are attached to a fanciful shroud/frame. The visible
portions of the assembly are composed of hard, semi-translucent plastic
except for three small platforms jutting out from the motor which are
equipped with blue LEDs. The fan is an Everflow FB14025BL, which
indicates it has ball bearings, though Thermaltake does not list a bearing
type in its literature.


The fan assembly is held on by two tabs pressed into ridges on
the sides of the heatsink. It can be removed quite easily, though it is
actually fairly secure. The fan is hard mounted to the cover, but one
corner of our sample was damaged, allowing us to see that springs are
incorporated into the design. This corner was taped down during testing
so it wouldn’t affect performance or noise.


The heatpipes are packed very closely together with little room between them. The fan has a manual fan speed controller knob included — a common feature of Thermaltake products.


The fins are friction-fit to the heatpipes, with no solder joining
the two components. Fin spacing is very narrow.


The gaps between the copper base and heatpipes are soldered however. The base is much larger than the average CPU heatspreader.



The base was very flat and had a beautiful mirror finish. It’s
one of the things Thermaltake usually gets right.


Installation on AMD motherboards is facilitated through a familiar set of tension clips. The broad side of the heatpipes will face the rear exhaust in most AMD systems.


LGA775 installation requires a pair of mounting clips to be screwed
onto the mounting plate. Washers are affixed to each leg to prevent
over-tightening. These legs are then slid through the LGA775 mounting


To secure the legs on the other side, Thermaltake provides four small
steel nuts that can be tightened via screwdriver. While it is indeed
secure once tightened, getting them started on top of the supplied washers
can be a bit tricky, especially for those with clumsy fingers. This
step is probably best accomplished using the heatsink body to prop the
board up at an angle.


The BigTyp’s width may cause problems for some system configurations.
On our test motherboard, an Asus P5Q-EM, it extends past the top edge
of the motherboard by about 2cm, which is likely to interfere with the
power supply in a typical ATX case. It also covered two of the motherboard
mounting holes and extended over the I/O panel.
A case with
a rear exhaust fan may prevent the BigTyp from being installed.

Testing was done according to our
unique heatsink testing methodology
, and the included fan was profiled
using our standard fan testing
. A quick summary of the components, tools, and procedures
follows below.

Test Platform change:
Due to the amount of wear and tear to which we subject this test platform (which we also use for hard drive testing) it was decided to replace the motherboard with a newer, more current model that could be easily replaced should it be damaged. Asus kindly provided us with two P5Q-EM’s — one will be kept as a spare in case anything happens to the original. Testing showed that the CPU temperature reported by SpeedFan on the new motherboard was exactly what it produced on our original platform. The hard drive was also replaced with a solid state drive — the system now has no moving parts aside from the products we evaluate.


Key Components in Heatsink Test Platform

  • Intel
    Pentium D 950
    Presler core. TDP of 130W; under our test load, it measures
    78W including efficiency losses in the VRMs.
  • Asus P5Q-EM motherboard. A microATX board with integrated graphics
    and short solid-state capacitors around the CPU socket, and a diminutive northbridge heatsink for maximum compatibility.
  • Intel X25-M
    80GB 2.5″ solid-state drive.
  • 1GB of Corsair XMS2 DDR2 memory. 2 x 512MB PC2-8500.
  • FSP Zen 300W
    fanless power supply.
  • Arctic Silver
    : Special fast-curing thermal interface material, designed
    specifically for test labs.
  • Nexus 120 fan (part of our standard testing methodology; used when
    possible with heatsinks that fit 120x25mm fans)

Measurement and Analysis Tools

  • Seasonic
    Power Angel
    for measuring AC power at the wall to ensure that the
    heat output remains consistent.
  • 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 sensor. This sensor is not
    calibrated, so results are not universally applicable.
  • CPUBurn
    , used to stress the CPU heavily, generating more heat than most
    real applications. Two instances are used to ensure that both cores are stressed.
  • Throttlewatch
    , used to monitor the throttling feature of the CPU to determine
    when overheating occurs.

Load testing was accomplished using CPUBurn to stress the processor, and the
graph function in SpeedFan was used to make sure that the load temperature was
stable for at least ten minutes. The stock fan was tested at various voltages
to represent a good cross-section of its airflow and noise performance.


Stock Fan Testing

Testing was performed using an external voltage controller, with the BigTyp’s
controller was set to maximum speed. At minimum, the controller drove the fan
at approximately 820 RPM, roughly equivalent to a 7V input. Ambient conditions
at the time of testing were 20ºC and 11 dBA.

Fan @ 12V: At full speed, the BigTyp’s fan was loud, turbulent and very
buzzy. The measured noise level was 37 dBA@1m.

Fan @ 9V: The fan was noticeably quieter than at 12V, but is still
unacceptable. Subjectively, it sounded very breezy and turbulent.

Fan @ 7V: This level was much more reasonable and surprisingly smooth,
with chuffing detectable at close proximity (0.5m or less). The SPL was 21 dBA@1m
which is quiet enough for the average end-user.

Fan @ 6V: With much of the turbulence gone, the noise came from the
fan’s bearings. Some bad undertones became noticeable as the fan speed was reduced.
The overall SPL level was only 18 dBA@1m — enough to be audible in a silent
PC, but still very quiet.

Fan @ 5V: At 5V, the SPL reached 14 dBA@1m, which should be
inaudible in most system configurations. Heard close up, the fan produced a
low pitched hum, and the chuffing noted at 7V was more pronounced.

At full speed, thermal performance was excellent: only 13°C above ambient.
At 9V, the CPU temperature increased by only 3°C, while 7V produced a further
2°C degradation. At 6V the BigTyp’s cooling proficiency started to take
a big hit — 4°C higher than at 7V. The sweet spot
is somewhere between 6V and 7V. At 5V the BigTyp really began to struggle —
the CPU temperature increased another 6°C. The BigTyp seems to be in its
element when airflow and noise are high.

Compared to the Zalman CNPS9300
, the BigTyp 14Pro is a significant improvement, posting better numbers
at more or less equivalent noise levels. The CNPS9300 is a fairly light, modest
cooler however. When pitted against the CNPS9900,
a heatsink closer to the BigTyp’s weight, size, and cost, it fared poorly. As
a top-down cooler, it had a tough time competing with east-west blowing CPU
heatsinks — maybe a comparison against other top-downers would be more

BigTyp 14Pro with stock fan @ 5V;
Comparables with Nexus 120mm fan @ 9V (noise equivalent).

Unfortunately, the BigTyp 14Pro’s poor low airflow performance is clear even
when compared to other top-down coolers we have tested (our reference Nexus
120mm fan was used). At 5V, the BigTyp’s fan measured 14 dBA@1m and had a thermal
rise of 28°C. Yet, every other top-down heatsink in our comparison manages
to outperform it at the marginally quieter 13 dBA@1m that a Nexus 120mm produces
at 9V. It may be somewhat unfair to pit the BigTyp 14Pro to compare it with
heatsinks using one of the best 120mm fans on the market, but it does give us
a consistant point of reference.

Unfortunately, the most obvious competitor for the BigTyp, the
Scythe Zipang
, was not included in the comparison because we no longer have
the product sample. However, it turns out a direct comparison was unnecessary
— the Zipang is the most efficient top-down cooler we’ve ever tested, and
the BigTyp couldn’t even fend off smaller heatsinks like the Xigmatek
or Thermalright
. Even the BigTyp’s predecessor, the Big
Typhoon VX
, pulled off better numbers at least when equipped with a quality
120mm fan.

When we originally tested the Big Typhoon VX (pre-anechoic chamber), the stock
fan at 5V was approximately the same noise level as the Nexus fan at 9V, but
performed 6°C worse (30°C thermal rise). If we use this indirect comparison,
the BigTyp 14Pro outperformed its predecessor by an insignificant and disappointing
2°C. Considering the size and price of the BigTyp, we were expecting a more
substantial difference.


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 10 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.

Reference Comparatives


Despite its girth, longer heatpipes and 140mm fan, the Thermaltake BigTyp
14Pro is a relatively poor performer once the fan speed is dialed down to tolerable
levels. While we did not expect it would be able to compete with the massive
tower heatsinks which have the inherent advantage of exhausting air toward the
back of the case, the BigTyp also posted below average numbers against some
of the more modest top-down coolers we’ve tested in the past.

The combination of high fin density and a frameless fan are not conducive to
quiet, low airflow cooling. Without a frame, the fan produces very little static
pressure, making it difficult to force air down through the narrow gaps between
the fins, especially when the fan speed is reduced. Also, the heatpipes don’t
have a lot of breathing room between them, so the heat coursing through them
is not easily dissipated.

While bigger sometimes really is better, this is not the case with the BigTyp,
which barely outperforms its smaller predecessor, the Big Typhoon VX. Increasing
the heatpipe length along with the fan size did not appear to make it a better
performer, but it did succeed in making the BigTyp one of the more expensive
CPU coolers you can buy today. Being bigger causes other problems as well, such
as potentially interfering with power supplies or rear exhaust fans and obscuring
at least two mounting holes on the motherboard. Its lackluster performance isn’t
worth the cost to procure it or the possible problems associated with its installation.
