Will using low static pressure fan in front and high static pressure fan in back of radiator work?

Hi there, I just bought a NZXT Kraken X62 and two extra NZXT AER RGB fans to use on it. Turns out my case (Coolermaster Mastercase maker 5t) will only support either two 140mm fans pulling on the Radiator (radiator is exposed so you can see it directly), or four push pull configuration on it. I installed the stock fans as pull because I want to see the RGB fans... I then put the RGB fans in the front as push. The two stock fans have these specs:

Air Pressure: 0.21~2.71mm-H2O
Air Flow: 27.27~98.17 CFM
Sound Level: 21~38dBA
Fan Speed: 500~1,800 +/- 300 RPM

The RGB fans have these specs:

Air Pressure: 0.17 – 1.52mm-H2O
Air Flow: 30.39 – 91.19 CFM
Sound Level: 22 – 33dBA
Fan Speed: 500-1,500 RPM

Will this work well? I do not want to buy two more Aer RGB fans and hide them behind the radiator to maintain an equal static pressure... I also care about sound level, I want to keep them as low as possible... Is it plausible for me to make all the fans run at the same speeds and sound level with Asus Suite software?

Well, your configuration does work but you may loose CPU cooling performance if you use AER RGB140 fans on Kraken rad.
While AER RGB140 fans offer a lot of eyecandy (i also have two of them in my Skylake build, full specs in my sig), they are built as air flow fans with mediocre static pressure.

Though, since Kraken stock fans have similar SP values as AER RGB140, you should be able to get same static pressure out of both of them if you run them at the same RPM (500 - 1500).

As far as sound level goes, keep in mind that you'll get extra noise for air passing through the restrictions in the rad.

I take that you also bought HUE+ so you can control the LEDs inside AER RGB140.
