For anyone who believes
that overheating memory is the root cause of system instability, Forcetake's Mars RAM
Coolers may be just the trick. The kit includes two passive RAM
heatsinks for single or double sided DDR/DDR2/DDR3 memory, several thermal interface
pads, and all the necessary hardware you'll need.
You supply the RAM.
Mars RAM heatsink is more than just a stamped aluminum plate like a lot of the
memory heatspreaders in use by manufacturers themselves. The Mars cooler is in fact two
extruded aluminum sections which are clamped together around a U-shaped heatpipe with
dense copper fins, and the memory module itself.
A mechanical clamp keeps the RAM cooler in place, which is
an important distinction to take note of because genuine thermal interface
pads are used, not double sided tape. Many memory heatspreaders are held together by nothing
more than double sided tape which is not designed for heat
Frag tape is basically just sticky double sided tape,
it's made to stick things together, it's not known for conforming to different
surface heights or being especially thermally conductive. The Forcetake
Mars cooler uses thin thermal interface pads which conform around the
different surfaces on the side of a stick of memory to better transfer heat to
the aluminum. Two thicknesses of thermal interface pad are supplied, so this
heatsink can also be used with double or single sided memory modules. If enough
heat is produced by the memory, the Mars cooler has a small copper heatpipe
mounted atop each module to further aide cooling.

Each copper heatpipe
is covered the full length in thin copper fins that take advantage of
airflow across the memory region. The heatpipe may be rotated to the left or right
of the memory module, depending on the positioning of dual channel RAM in your
computer system. This is a pretty unique feature to the Forcetake RAM cooler, we
can't recall any other memory cooling solution which offers this level of
There are many instances where the CPU heatsink
or optical drives overhang the memory
slots, being able to rotate the heatpipes so the Forcetake Mars RAM cooler
becomes effectively shorter can mean the difference between using this product
and it not fitting.
respects installation is quite straight forward. Forcetake's Mars
RAM coolers are intended for DDR, DDR2
and DDR3 memory modules, and assuming the sticks of memory you have are
bare, installation is a quick affair. A thin strip of thermal interface material is
first laid down on the DRAM, and then the anodized aluminum heatspreaders are set in place.
Once installed, the heatspreaders widen each RAM module to a thickness of 9.5mm. On some
motherboards you will be able to install memory modules with the Mars RAM cooler
side by side, on others you will not.
If your memory already has heatspreaders attached
with adhesive or frag tape, there's a good chance you may destroy your memory if
you attempt to remove the heatspreaders, so don't. Our experience removing heatspreaders
from old memory has been successful when the DRAM is the TSOP-II formfactor, and
the adhesive isn't too sticky. Most early DDR2 DRAM was TSOP-II, and almost
every DDR DRAM we've come across is. Later generation DDR2, and DDR3 is packaged
in a BGA IC formfactor. That kind of RAM package doesn't suffer flexing very
well, and we've destroyed some very expensive memory attempting to remove
heatspreaders so we do not recommend you try it yourself.
