Package and Appearance

Cooler Master decided to mix things up a bit with the packaging, resulting in a look that's a bit different from other power supplies. As usual, this is just a gimmick and not necessary, but every company feels the need to come up with something "special" to attract the attention of potential buyers. The two sides of the package swing open to reveal the power supply within. Cooler Master lists all the important information on the slip around the package, which allows them to reuse the main box and simply change the paper slip for each different model.

The power supply looks cool with a gigantic 140mm fan that covers the whole bottom area. The front and rear of the power supply have a rubber frame that helps to dampen vibrations during operation. This is another marketing bullet point, but in this case it actually does some useful work. Like most other power supplies, once again we have a black housing with a perforated back that lets the air exhaust from the housing.

    You're quite incorrect. The method for heat transfer from the heatsinks to the air is the same for both copper and aluminum. If you took a heat transfer course you'd know that the thermal conductivities and convective heat transfer coefficients are what is used in the heat transfer equations. No where is it dependent on the heat capacity. So, you have
    Q=K A (Tb-Th) where Tb=base temp, Th= heatsink temp, then heat transfer to the air is
    Qa=h A (Th-Ta) where Ta is the bulk air temp. These are highyl approximated, as there are multiple layers. Now, look at the equations...if K for Cu is greater than for Al, heat transfer is faster. What this amounts to is a greater Th, but look at the second equation, if Th is greater, the temperature gradient(or driving force for heat transfer) is greater than it would be for aluminum. Copper is a better material for this application. It's just expensive, and it oxidizes, which is why we have nickel plated copper heatpipes.

    Great explanation mate. Reply

    It's an old tale but it's just that a tale.

    Weight has probably a lot to do with it on modern coolers, I have a Tuniq Tower 120, think of this cooler in pure copper, it would snap the motherboard with it's weight probably. We haven't moved to coolers weighing 2-3 kg yet. But as always price is the main factor.

    'Transfer' and 'dissipate' are different things. The copper plates transfer heat away from the components better; the aluminum fins dissipate (exchanges may have been a better word choice there) the heat into the air. This is not unlike those heatpipe tower-style CPU coolers. Reply

    Thanks mate. Reply
