Radiator cooling information.

I'm new to watercooling, but come from an engineering background.

The information that i'm after is the following.

There is an elementary equation from basic thermodynamics that states that the rate of heat transfer (Q) equals the mass flow rate (M) times a Constant (the specific heat of water) times the Delta T (fluid temp out minus fluid temp in):

Q = M x C x Delta T

The problem that i have, i cant find any info on the radiators to work out the heat transfer to get the temp change in the water. I should be able to work out the temp in (as i'm aware of the amount of wattage mu cpu is using.

Can anyone point me in the right direction to find information on radiator cooling information?

As i want to calculate the correct size rad.

This might be useful for you:

Gives comparisons of a lot of the common water cooling radiators and the number of watts of heat they are capable of dissipating at a given temperature delta at specific fan speeds (and therefore noise levels).

However my personal opinion is that if you are only cooling your CPU a 120.2 will manage to keep it cool very nicely while remaining very quiet.

Thanks, gut feeling was a 120.2. But it is not going to hurt to try and work it out.

based upon the link there tends to be very little between all of the tested rads.

Thermochill seems like a good point to start @

Skinnee labs has the best compilation of radiator cooling capacities, and other watercooling-based technical information, anywhere on the web. At least that I've come across...

Truly a fantastic site.
