Question AIO location

[MrTwister231]

All,
starting a new build and its been a while.
Setup:
I-5 9600K
MB MSI MPG Z390 Gaming Edge AC LGA1151
Case CORSAIR CARBIDE AIR 740 ATX Cube Case
Cooler CORSAIR HYDRO Series H115i PRO RGB AIO Liquid CPU Cooler,280mm.
Location Temp: Miami Fla room temp High 75F
Question: Considering where to place the AIO. Any reason why I shouldn't pace it at the bottom of the case as an intake>>pulling cool air through the RAD?
Orther intake is two front 140mm fans.
exhaust would be two top 140mm fans and one rear.
Power supply sits in a different compartment https://www.amazon.com/gp/product/B01LHFLPB4/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
Thanks for your time and efforts.

I'd not put it directly on the bottom of the case. Apart from the conflict of interest when it comes to air intake with the psu, conflicts with psu wiring, it's also the dustiest intake area. Generally the front or top exhaust is a better option.
I used 2x 140mm as intake and then exhaust and a kraken x61 as exhaust and then intake, basically the same results. With a 280mm aio you don't even need a rear exhaust.

Thanks for the reply but the case is a cube case and the power supply is in a different compartment.

I have an AIR 540, pretty much the same shape/size of your 740.
280mm Cryorig A80, top mount exhaust.
2x 140mm front intake, and 1 x 140mm rear exhaust.

I would not put it on the bottom of your case.
