Cooling Ive Bridge and GTX680

Postby Isamun » Mon Jul 02, 2012 6:53 am

How will two HX-CU420V and one HX-CU720V with four FAN-12025HBK handle a i7 3770k and a refrence GTX680?

Basic way to estimate rough performance is take the max wattage of what ever your cooling
ie.
3770k ~= 150W (not overclocked)
GTX680 ~= 180W (not overclocked)
Rough total of 330W (not overclocked)

HX-CU420V estimated 400W
HX-CU720V estimated 700W

330W vs 1100W means the radiators should work well even at slow fan speeds. This isn't exact but is a good way to estimate what is needed.

IN THEORY a lone HX-CU420V might be enough but to reach the max estimated wattage but you would need high speed/high noise fans to get away with it.

Thank you for your comment. I am aware of the heat dissapation listed, but I've seen in testing it can prove somewhat lower then the listed spec.

SkinneeLabs managed to get 600-800W from the CU1020V at 1800-2600 RPM below dt 10. That rad is spec'ed to 1000W.

Is it then safe to assume that the CU720V will dissapate approx: ((700 X 0,6) to (700x0,8)) = 420 to 560
and the CU420V: (400x0,6) to (400x0,8) = 240 to 320
as an estimate for that RPM range?
(I do also beleive that the Koolance fans have better airflow and static preasure then the Late Yoons he used.)

Even with these calculations the two singles and the double would dissapate from 900W to 1200 W which sounds great!

If I have fundamentally missunderstood or missed something, please have at me!

Thanks

Thanks for your answer. Will a PMP-400 and COV-RP400 be capable of such a configuration?
