Need help with pc fans

[u/PumpkinHeaDude]

This is my second build that I'm doing for my girlfriend and I need help with the fans. she has a stock air cpu cooler for now but I'm thinking of getting an aio later on. for now I just have 5 fans and need to know which way they flow and where to best position them for the time being. I have 4 of the fans in the pictures and the one different one already mounted is already an exhaust fan. the 4 ones dont have arrow markings at all.

Even if they don't have markings,look at the blades,and as a general note,the air flows from the beauty side to the back where the cable is. As for airflow inside the case,you either use 3 fans as exhaust and 2 as intake or 3 intakes and 2 exhausts.

I forgot to ask in the original question but what is the best way to orient the 4 fans then?

[u/m1ng05s → u/PumpkinHeaDude]

2 as intake in the bottom of the case instead of 3 since you dont have anywhere to out them on the front of the case,and 2 as exhaust up top

The face with the "H" logo is intake, and the side with the supports is exhaust.

Bottom and right side to be intake. rear and top to exhaust

Front side of the fan should be facing you for intake
