improved perforamnce of 2 radiators

Just putting in my first WC cooling unit

Whitewater waterblock
Danner Mag 3
Dtek Procore radiator

have not started yet cooling pump came was broken have to RMA it

I was looking at my case when I realized that I can fit 2 rads in my case. How much of a performance increase if any on average is there with 2 rads. you get increased heat dissapation and decreased flowrate so does a second rad help???

Thanks in advance

if you are worried about decreased flowrate, you could run the radiators in parallel rather than in series.

it should give better temperatures than 1 radiator, but I've no idea how much.
