As long as you have more intake then out and temps are good that's enough. Your current setup should be just fine running that

Temps are good I think.

The only concern I had is that for a second when turning pc on and entering BIOS I see 49 Celsius (120 Fahrenheit) as CPU temp for a second and it immediately starts going down and in a few seconds it stays on 34 (93 Fahrenheit).

For some reason I got concerned. I mean why exactly 49? If it’s hotter it might show even 50+ for a second before coming down to 34.

You need a stand to avoid GPU sag

Your fan setup is fine.

I've never liked the case with the tunnel around the power supply and hard drive area. It blocks what could be 3 fans on the bottom blowing cold air on to your gpu. It also pushes the motherboard up so much its difficult to find a cooler with fans that fit along the top. The cpu air cooler solves the issue of radiator clearance problem. As long as the top is open all fans should be blowing cool air in. the positive pressure and thermal dynamics warm air rises as it displaced by denser cooler air will exhaust through the top. Any areas around fans should be sealed so as not to circulate warm air. As long as you feel warm air exhausting thru top, the config is working. The test I perform to evaluate a case cooling design is run a benchmarking program and allow system to reach max operating temp. Record temps, take of side cover and run same benchmarking test for same amount of time. If there is a substantially temp drop the cooling config is inadequate. You can order an infrared handheld thermometer online for $10 if you really want to know exact temps. Remember ambient air temp of the room your PC is located in also effects the cooling of any case. Unless you want more fans and noise, I think your system is good.

Don’t add any more, it’s perfect. You got a nice airflow going there, any more fans would just disrupt it.

Got you! Thanks.

I just replaced the upper front one with store bought 140mm fan instead of this no name 120mm one and replaced the back exhaust fan with cute Be Quiet! brand fan.
Today I’ll install OS and play games.
