Are these rads enough for cfx + cpu cooling?

post #1 of 4
Thread Starter 
I am planning on getting an Arc XL case when its available. I can install two Monsta 240s in it, one at the front and the other at the top. Or I can install a 360 slim at the top and a 240 Monsta at the front.

Which of the two setups should I go with?

Will it be enough for a 4670k and two 9970s all being overclocked?

Thanks thumb.gif

I would go with the 360 + 240. Thickness of the radiator is far less important than most make it out to be, due to the many complicated laws of thermodynamics. Basically, while you would think that a 60mm rad would have 2x the surface area of the same model that's 30mm thick, the effective surface area is actually very similar, because as the air travels through the rad fins it picks up heat, and by the time it's halfway through the difference in temperature between the air and fins is too small for it to effectively pull much more heat away.

I would also only get the Monsta if you are going push pull, otherwise I would stick with the UT60, and for the top either the XT45, EX360, or ST30 will be ideal depending on the total depth.

Yeah I was thinking about going UT60 because I am gonna skimp on fans. I will also get ST30. Thanks for your help +1 smile.gif

This is only the case if you don't have enough air flow for the heat load in question.

Two thinner rads are easier to cool than one thicker rad, but force the same volume of air through the thicker one and temps will be very similar.
