I
noticed that on your website there are two types of
HR-09. What are the differences between them?
Answer
:
HR-09
has two distinguish types: the slanted version S and
the upright version U (sold separately). The slanted
version has two heatsinks in diagonal with each other
while the upright version has the two heatsinks directly
above each other.
HR-09
has two types. How do I choose which one to install
on my motherboard?
Answer
:
If
your motherboard is by ASUS and its single MOSFET
is near the I/O port, HR-09U would be the ideal version
to install since HR-09S would more than likely get
interfered by the surrounding components. But if your
motherboard is of Gigabyte, You can purchase two HR-09S,
or one HR-09S and one HR-09U depending on the size
of your CPU heatsink.
My
motherboard does not have the heatpipe cooling solutions
for my MOSFETs. Can I install HR-09 on my motherboard?
Answer
:
HR-09
was specifically designed for motherboards that have
the heatpipe cooling solutions. We have received many
requests from users who claimed that their stock MOSFET
cooling in not affective and that they are hesitant
to install HR-05 because MOSFET solution would not be
covered. This was the main reason for the come about
of HR-09. HR-09 utilizes the push pin installation method.
For that reason, motherboards that do not have the push
pin type MOSFET will not be compatible with HR-09.
I
have a Gigabyte DQ6 motherboard that has quite an effective
cooling solution for its MOSFET. Would I get an even
better result with HR-09?
Answer
:
In
our own lab tests, results have shown that there is
a difference of 5-8 Celsius degrees after the installation
of HR-09 on the Gigabyte DQ6 motherboard. If you were
to install a HR-05 for the northbridge chipset, you
would have an even wider range for overclocking.
I
have an eVGA 680i motherboard. The MOSFET cooler on
the board is extremely hot to the touch and I・m thinking
of installing your HR-09. My question is: is HR-09 compatible
with my motherboard?
Answer
:
HR-09
was designed based on motherboards by major manufacturers
such as ASUS and Gigabyte, and MSI. We have received
quite many requests and inquiries from end users for
other brands of motherboards. As we have in the past,
we do try to satisfy the demands of our utmost supporters.
But due to the many variations (even within their own
range of boards) in mechanical layout by motherboard
manufacturers, it・s hard to please everyone. However,
we will continue to diligently come up with new solutions
for those who have the eVGA, DFI, and/or Abit boards.
We will post the newest information on our website as
soon as we have anything.
Is
MOSFET cooling really that important as most high end
motherboards now have their own MOSFET cooling solutions?
Even Thermalright got into the picture.
Answer
:
One
of MOSFET・s major functions is to regulate voltage
stability for any given motherboard. The more power/voltage
you increase the hotter the MOSFET runs. Thus, MOSFET
cooling is considered vital to overclockers. This is
where Thermalright comes in to save the day. Motherboard
manufacturers try to market their boards by having what
looks to be an impressive MOSFET heapipe-line cooling
solutions when in actual they don・t do much except
looking good. The result is a hot and unstable MOSFET
(especially when voltage is increased in overclocking
CPU and/or the Northbridge chipset). HR-09 with its
no none-sense design is specifically to cool the MOSFET
without any gimmicks. Thermalright will continue to
satisfy the hungry overclocker in all of our supporters.

I still have more questions
FAQ 7
Question
:
My
HR-09 does not cover the entire MOSFET. Would that create
a problem?
The
first picture shows the MOSFET after the stock cooler
has been removed. As you can see there are 16 of
them. But looking closely you can see from the thermal
compound imprints that only 4 are in complete contact,
and 4 was only covered by about 1/5. Picture 2 shows
the remaining MOSFET toward the left.
The
third picture shows the upper area of MOSFET. 5
MOSFET are partially covered. The fourth picture
shows the MOSFET stock cooler not covering every
MOSFET.
The
fifth picture shows the HR-09 on the MOSFET and
covering more MOSFET than the stock cooler. The
sixth picture shows the range of the thermal pad
as it was designed in accordance to the push pin
mounting holes. The HR-09 mounting mechanism can
only stretch thus far.
The
seventh and eighth picture show that larger MOSFET
area has been covered as the shorter end of the
HR-09 is intended for ASUS boards and the longer
end is intended for Gigabyte boards (we are currently
developing MOSFET solutions for Abit, DFI, and eVGA
boards).
In conclusion, the problem of not having the MOSFET
entirely covered originates from their own stock
cooler and having variety of layout certainly does
not help either, therefore it is hard for us to
guarantee the compatibility for every motherboard,
but we will continue to improve. If your motherboard
has its own heatpipe cooling system, you can consider
replacing it with out HR-05, HR-05-SLI, and HR-09
for better cooling solutions.
