I have to choose one from these 2 brothers

[Royteane]

Alphacool UT60 240 or Ut45 280

to be used with AP-15(with 5mm adaptor for 280). They're looked equally bad in the build but I need their multiple ports as drain/fill.
Only performance considered, which one you guys prefer?

280 will likely prevail, much more frontal area which is key where the extra thickness only makes fairly minor gains.
