True?

So apparently for what I have been getting told a 120mm rad like the one the H75 has can perform just as well as say a 240mm rad. 

I took a second to really think about that and I thought that since the 240mm rad has a higher surface area it will perform much better then the 120mm rad. if this is anyway false please let me know why.

Whoever told you a 120mm closed loop cooler can match a 240mm dedicated rad on heat dissipation is full of shit, I could understand if it was a 120mm rad with huge thickness and hence increased surface area but the H75 is not.

There is a difference, not really that big (unless it's using really high-end fans).

 

But A bigger surface area is ALWAYS better!

If the 120 is twice as thick as the 240, they should perform about the same.

It depends on the thickness. If the 120 is the same thickness as the 240, the 240 will perform 2x better.

If the 240 is twice as thick as the 120, it will perform 4x better.

When someone tell you things like this you should ask them to explain why. Then sit back and /popcorn.

Not necessarily.  There are other factors such as fans, fin density, etc.

This is considering fans and fin density are the same...
