Asus G16CH cooling upgrade

Hello everyone, I am new to gaming on desktops, so I don't know much..

for some backstory, ive always had laptops for as long as i can remember.. I am big into flight sims and other simulation games, and have always dealt with having to lower graphics to be able to run MSFS or ETS2

I purchased this Asus desktop a week ago from Newegg. here are the specs:

Intel Core i7-13700KF 3.40 GHz
32 GB DDR4
1 TB M.2 NVMe PCIe 4.0 Performance SSD
NVIDIA GeForce RTX 4080 16 GB GDDR6X
850W power supply (80+ Gold, peak 900W)


at the time of purchase, it cost $2000. I basically wanted a good starter desktop that i can upgrade in the future, slowly but surely.
I also purchased and Asus TUF 28 inch 4 k monitor.

basically, I read that the case has poor ventilation, but i assumed it would be alright for a little bit.
I loaded up Microsoft flight sim yesterday, and the graphics were stunning! however, i opened up armory crate, and noticed my CPU was at 100c.. which is from what ive read, very high.. when im just on chrome, the cpu is chilling at 57 c.. so if fans can bring it down to 70c id be very pleased with that.

I don't really want to be playing the game and burning my 13th gen i7..

i reread some reviews from new egg, and i decided to order 2 80mm fans and 2 120 mm fans from Arctic, they will be arriving tomorrow. However, I don't know exactly how to upgrade the fans, from what i can tell, there's only exhaust fans, one on the back and one what i assume is 120mm on the top, meaning yes, there's no intake fans in the front... which is a real bummer considering this is a prebuilt from Asus..

So what's the best step for me? adding the fans with zipties? changing out the heatsink? going with an AIO ( which I'm hesitant about, i don't trust the liquid near this expensive peace of equipment!

now, I've never taken the desktop apart, I'm not sure how to open it, but I'm willing to learn and upgrade it, there looks to be space in the from to add two or possibly 3 fans for air intake.
down the line i want to port over everything to a new well ventilated case, but don't have the knowledge yet on how to do that.

Id appreciate some help from you guys! I am an aspiring pilot and wanted to practice on Microsoft flight sim.

Thanks in advance, and here are some pictures!
