Universal Design: compatible with Intel Core 2 Quad, Core 2 Extreme and Core 2 Duo and AMD Athlon 64 FX and Athlon 64 X2 Duo core
Board and CPU Cooler Design: cools CPU and its surrounding components (motherboard, memory, VRM, chipset and etc.)
Superior Cooling Performance: copper base, 5 heat pipes and high density aluminum fin
Unique Fan Bracket: for mouting one 120mm fan/two 90mm fans/two 80mm fans
Silent Operation: at only 19 dBA |
 | Pure Copper Base
Pure copper base maximizes heat transfer quickly |  | Silent 120mm Fan
Sickle blade design produces huge airflow and decreases noise |  | 5 Heat Pipes / High Density Fins
5 heat pipes transfer heat to the fins efficiently
High density fins creates excellent heat dissipation |
| Special Features | CPU and Board Cooler
The default silent fan (120x120x25mm) can be easily exchanged to two 92mm/80mm fans for complete cooling solution. It draws cool air to cool CPU and its surrounding components (memory, VRM, chipset and etc.) |  | Flexible Fan Bracket Design
Flexible mechanical design supports single 120mm fan or two 92mm/80mm fans. And the adjustable bracket is movable to avoid any interference
**80mm and 92mm fans are optional |  |

"The Geminii S performed fairly well, keeping pace with the Shuriken and LOW-7000
until fan speeds were decreased drastically. It's affordable, has a good solid
mounting system and ships with a surprisingly good fan with excellent acoustics.
If you have enough space to accommodate the Geminii S, it is a worthwhile
investment."

This CPU cooler has a lot going for it. Starting with pure aesthetics, this is
one nice looking unit with a unique design. Four separate banks of cooling fins
are sandwiched by a 120mm fan, all of which are connected to the base of the
heatsink via eight different heat pipes. Cooler Master integrated a
rheostat-style fan speed controller, accessible by using the included add-in
card slot. All of the necessary hardware is included for installation as well as
a tube of thermal paste.

The Cooler Master GeminII S
isn't exactly perfect but I think disregarding the minor problems of this
cooler the GeminII S is a great value.
There are many places online to buy this cooler, all of which price for about
$35. Considering that this is one of the
better CPU coolers we've reviewed
when it comes to cooling temperatures I have to say this is a Good Value.
ThinkComputers awards the Cooler Master GeminII S CPU + Board Cooler an 8 out of 10 score and our Good Value Award.

Apart from the laborious process of getting
this cooler installed; testing this CPU cooler was an extremely fun and
rewarding process. I used an AMD Opteron
1214, a processor known for putting out quite a bit of heat while under load. The CoolerMaster
GeminII
S lived up to the marketing hype and the legacy of the other CoolerMaster
products. Using the default thermal compound the GeminII S kept my fully
loaded processor within 4.7 Celsius of the ambient tempterature while fully
loaded. The Stock OEM cooler was only
able to maintain a 12.2 Celsius differential making the GeminII S around 60%
more efficient.
Overall, I was very impressed by the performance and construction of this product.
My board and configuration does not support overclocking, but I would expect
that if one were to try this cooler out
in an overclocking situation that it would easily allow a 300-800Mhz overclock
on just air cooling. These numbers depend of course on many other
factors but are a good guess based on the temperatures that I was able to
maintain with this cooler. At an average
selling price of around $40, the CoolerMaster
GeminII
S would make a welcome addition to your already hot rig.

“Overall the
Coolermaster GeminII S is a very good heatsink for both Intel and AMD
platforms when running at full fan speed, particularly if we consider
its compact height…bottom line, the Coolermaster GeminII S is a good
thermal option hampered by cumbersome mounting system.”
