    What does Watts of cooling actually mean?

    Many CPU coolers have wattage rating on them saying how many watts of cooling they provide. But to me this is just an arbitrary scale because i am not entirely sure what is actually means.

    Does it mean that if my CPU is overclocked to an extent that it draws 150watts of power, does that mean that i need a cooler capable of cooling at least a 150watts?

    If not how would you go about finding out how much cooling power you would need for any given system?

    Also is there a way of calculating how many watts of cooling any given watercooling radiator is able to provide?

    Thanks for any responses in advance

    too many factors, the rad is not the only thing in the equation, you have the fans that count, the pump, the restriction of the water-block will influence the flow. the capacity of the block to transfer heat to the coolant.

    Martin make a calculator, but it's not complete. The best is to experiment and have a lot of cash to correct the mistake.

    The "Watts" your speaking of are a measure of heat energy, not electronic current draw.
    Sorry but I don't remember the equations to arrive at the Watts of heat dissipation figures you're looking for, but I'm sure that someone will be along that can provide that for you.

    See as I typed some one shows up ! )
