HX-CU1402V & HX-CU720V

Postby Picollo » Sun Jan 08, 2012 12:34 pm

According to your graphs, the 120mm radi (CU720V) with the specified fans (FAN-1x025HBK), is more powerful than the 140mm (CU1402V) version.
And also smaller, lighter, cheaper and quieter.

Is there still any reason for the larger 140mm CU1402V ?

PS: sorry for the Googlenglish

The fans are not equal. The 12025HBK is not equivalent performance to the 14025HBK. They are fairly close but not the same thus the graphed performance of the radiators is different.

A 140mm fan will let you use lower noise same cfm/pressure fan to get the same performance for quieter etc and other options.

I've only just realized something.
All 140mm 30-FPI radiators share the same temperature and pressure drop measurements !?

We have all rads listed in the same graph, but they're color-coded in the bottom legend. They won't be the same.

Radiator performance primarily depends on airflow and size. An equivalent 140mm rad won't perform better than a 120mm rad if the airflow is a lot less, which is usually the case. 140mm fans tend to have lower air flow/pressure than 120mm fans (they're better if you're focusing primarily on noise reduction). You could purchase a 140mm rad for the larger area and pair it with high speed 120mm fans for even better performance, but you'd have to come up with a different way to mount them to one another.
