As the summer fades away into the scrap book and the holiday season fast approaches, Coolermaster has been working behind closed doors finding new ways to cool the hottest computers and just in time for the holidays.Fighting against the intolerable heat from the CPU entails the extreme action from the invincible champion – Mars, the new generation cooler for the latest AMD Socket AM2 and Intel Core 2 Duo brought to you by Cooler Master.


Coolermaster Mars

The special design of embedded fan with blue LED, enclosed in the dome shaped stacked fins, accelerates the heat dissipation process. Not only does Mars present a spectacular sight but also provides an effective cooling environment. The aluminum heat sink with three heat pipes provides excellent heat dissipation. And its intelligent Fan Speed Controller (PWM / Silent / Performance Modes) allows you to have total control over the cooling performance

The is one very large heat sink with about a 4.5 inch radius and has about 200 aluminum fins around the entire circumference from top to the base. There are three copper heat pipes that are intended for helping the main cooling feature: two pipes round up from the wire side and one pipe from the opposite. The base is also made of copper and while it's not completely polished it is very smooth and flat which is what really tends to matter for any heat sink or cooler.


Coolermaster did well to taper the bottom fins wrapping the base. In the past, many o' coolers from every maker had a bit of trouble as the size and width of the bases and fins encroached on vital motherboard real estate. The tapered fins should allow enough room to maneuver, service, and install other vital components such as the memory.

Wrapping the circumference of the Mars just inside the middle of the aluminum fins is another empty heat pipe to help with thermal dissipation. Within the very center is the 90mm fan that pulls and pushes are throughout the entire heat sink. The closest thing to resemble this fan I can recall was the old school Thermaltake Orbs with a fan within the heat sink fins that wrapped up around it.

Now, the other feature that might be something you're looking for in a CPU cooler. Within the center of the heat sink and fan there are two blue LEDs that are intended to give it that extra special affect.

The coolermaster Mars has the latest typical 4-pin power connector which of course works on any motherboard and if it just so happens it doesn't there are cheap wire adapters at any local PC store. Getting back to the fan, there is a 2-position speed jumper. The default setting 1-2 is the fastest speed bringing the fan to 3000 RPM. Setting the jumper to 2-3 sets it to the lowest speed at around 900 RPM. If you leave out the jumper and enable your system's automatic cooling in the BIOS, such as AMD's Cool n' Quiet, the fan will then be controlled automatically as well.



The Mars is best assembled on its top. The CPU bracket can then be mounted much easier after deciding a couple details. First, you just have to decide the orientation of the cooler and which way it will be facing and then mount the CPU bracket. Second, will it be able to reach the onboard CPU fan power. Afterwards, four motherboard standoff screws should be screwed on to the four corners for AMD and two middle holes for Intel of bracket. Now you can use the four small screws to permanently mount the mounting bracket to the base of the Mars.

Four rubber washers, depending on your particular motherboard and or CPU, are placed over the ends of the motherboard standoff screws after pulling off the white paper which allows them to stick to the bracket. I partially sat the Mars on the board to select what size rubber washers to use in the kit. The rubber washers will easily stick to the standoff screws when you finally install the Mars cooler. I found again, that leaving the MARS upside down on a soft surface will let you to center the motherboard over the bracket holes while you attach the four bolts to the standoff screws attached to the bracket. Very easy and simple this way. The included Phillips Socket included in the kit works great for tightening down the four bolts.

The Mars does in fact beat the stock AMD cooler that comes with the Opteron processor used. And on top of that, the Mars looks pretty cool with the blue LEDs. It does provide for a pretty original effect inside the case or whatever chassis you might have.

What about fan noise? The specifications list an average of 25dB in typical use. Being that it was on the tech station, the meter scored it at about 28dB from 2 feet away when full speed. At low speeds, the fan noise was about 18dB, which means it should be quieter in your case. I suspect the actual noise will be lower depending on the size and holes in your case.
