Don't want to keep people weighting because of all the wait you have to carry around

I just wanted to make a comment on copper vs. aluminum

Heat capacity: aluminum VS. copper

In addition to surface area and the air flow through the heat sink, the material which the heatsink is made of is even more influential in cooling. For instance, different materials have different heat capacities. The heat capacity of a material indicates the amount of heat energy (measured commonly in joules or calories) a certain type of material with a certain mass can receive before it's temperature goes up by a specific amount. The heat capacity of aluminum is measured to be 900J/kg*K, which means that for a 0.25Kg block of aluminum it will take about 1125 Joules of energy to have it's temperature raised by 5 degrees. The temperature of a 0.25Kg block of copper, which is measured to have a heat capacity of 386J/Kg*K, will rise by 5 degrees with only 483 Joules of heat energy. What the heck does that mean? Simply it means that copper will rise in temperature more than aluminum when the same amount of heat is applied. Does this mean that aluminum is a better cooling material than copper? Not necessarily, because there is a more important factor to consider: thermal conductivity.

Thermal conductivity: aluminum VS. copper -

Thermal conductivity, as it obviously implies, is a measure of how well a type of material can conduct heat. A higher thermal conductivity means a better conductor of heat. Copper has almost twice the thermal conductivity of aluminum (401 W/m*k compared to 237 W/m*k), which makes it a clear choice over aluminum for CPU cooling as it can transfer high amounts of heat more efficiently. The main reason for comparing aluminum and copper is because most older HSF products use aluminum for the heatsink, while recently the trend in cooling products is to use copper instead.

And another little clarification for anyone who doesnt know... The XP-90/120 have copper bases, they're just nickel plated to look blingtastic

It just basically means that between an XP90 and an XP90C , XP90C needs a higher cfm fan to get rid of the heat since copper can hold less heat than aluminum. XP90 , you can use a slower silent fan and still get away with it , but XP90C actually outperforms an XP120 when its coupled with a nice beefy delta or Panaflo becoz copper than dissipate heat faster.

Beefy Delta = OSHA thinks you should wear hearing protection while in the same room, lol.

I'll go with the XP-120 and slower fan thanks
