Currently have a 6700k and 1070 strix being cooled by a Ocool 420mm crossflow radiator. 6700k overclocked to 4.4 ghz. Both gpu and cpu have ek blocks and res is a photon 270 with d5 pump. Temps stay pretty low


Looking to change case to define s2 meshify so ill have to ditch the 420 rad and photon, too large. Looking at hardware Labs nemesis gts 360, one possibly two along with a ek pump res combo.

I will be upgrading to ryzen 3700x or 3800x in the near future also. Will i lose cooling for from a 420 35mm rad to a pair if 360 30mm rads ?

Thanks for the help
 
will you lose cooling, no. the 2x360 will be a little bit more cooling capacity

By 420, we are talking 3x, 140mm fan slots. If we do the math, that is 588cm2 of swept area.

For the two 360's you have 6x 120mm slots, so if we do the math, that is 864cm2, so you are talking about 47% more swept area with the dual 360's.

They are a little thinner, but not much, and in radiators swept area matters much more than thickness anyway, as thick radiators have limiting returns.

I'm pretty certain this will be a fairly substantial upgrade, not a reduction in capacity.
 
Thanks,.....

I should have just done the simple math and I may be doing it all wrong, not taking into account fin density and fan speed/ sizes.... also, my existing rad is 45mm thick, not 35 like I though

420mm x 45 = 18900
720mm x 30 = 21600

Of course I have no idea what those final numbers are, but bigger has to be better, lol.

I just saw your post after I responded, does what you said still apply since my rad is 45mm thick, not the 35 I thought ?

i get that, i didnt want to overstate the increase. :)

should be either 420x140 and 360x120 for surface area or 420x140x45 or 360x120x30 for volume. but i think zara is right, the the surface area matters more. the higher volume will hold more liquid which will raise the time it takes to reach max heat soaking, which usually isnt an issue.
