So I am 18, and I'm enrolled for PC Repair at my college. I've been pretty tech savvy throughout my life but I am a bit unsure about the cooling for my planned PC Build because I honestly did not consider this factor carefully enough before buying the case that I bought. I don't know about the exact RPM on the fans, but if this helps at all its a Mid-Tower and its of the Musetex brand. The build I'm going for is pretty high end, I don't have all the parts yet but I'm close so ill list off the parts that I have, and the parts that I plan to get.

Current Parts:

Musetex Mid-Tower PC Case

MRG Z690 EDGE WIFI DDR4 MSI Motherboard

Nvidia Geforce 4070 TI GPU

Corsair Brand RM1200x Power Supply

64gbs of RGB DDR4 G.Skill RAM

Samsung 990 Pro SSD with Heatsink 4TB

Here are the parts I plan to get to finish the build:

Intel I9-12900KF PSU

Seagate 12TB HDD

Be Quiet! Dark Rock Pro 5 Quiet Cooling CPU Cooler (Since my CPU is going to be high end, I do believe a heatsink like this will be needed)

TP-Link Wifi 6 AX3000 PCI-e Wifi Card (Archer TX3000E)

Those are the parts I plan to get, which is why I am concerned because the case I bought has 3 Intake fans (Which should be enough to keep the components and the internal temperature of the case down so I'm not too worried about that), but on the other hand, it only has 1 Outtake Fan which is what I am concerned about. With both the GPU and the CPU being pretty power hungry, will the one Outtake Fan be enough to expel all the heat from my PC Build? Or should I instead get a new case with additional or more Outtake fans? I'm also concerned about too much cooling though cause I know that could become a issue if I go too far with that.

PS: Its also worth mentioning that my 4070TI GPU has 3 Fans on it for additional cooling of the GPU as well.
