BQ Silent Loop 240 Installation: Fan Placement and 3pin Pump to 4pin Motherboard Connection

Hello. Current Fera 2 cooling unfortunately copes poorly with my OC processor. Replacement for a larger block and covering the board is not really seen because of the casing with a window. The choice fell on cooling AiO specifically bq Silent Loop 240. The only question is the installation of fans, the radiator I want to mount in the housing at the top and fans that will draw air from the housing through the radiator. Is it good idea? The installation of fans on the radiator can be limited by quite extensive cooling of the power supply section of the motherboard, I also want to maintain a relative order in the housing. I don't think I will improve anything in this housing because I used all the assembly places The housing is Gladius X60.
There remains the question of connection. 3pin pump, connector on the 4pin motherboard, you can only connect if the pins will be compatible? I see that the pin layout is different than the standard FAN ... and I don't see any bq pinout anywhere.

To start with, give your CD. What makes sense, I think that it is the most. Positive air circulation will be maintained, and if the computer is standing so that the air can escape freely, it can be done the most.

The plate is pictured with the connection of fans, Maximus VIII Hero. I have objections only because the manufacturer and the manual do not provide for such assembly.



Although picture 2 and 4 look similar, in this system the fans draw in air through the radiator but blow warm air inside which is a bit pointless.

So it will make sense, the so-called plume creates a swirl of air pushes the passing heat away, however, it carries the risk of scattering its parts inside, so such a system, but with the top hood it is the most effective and optimal.
