Hi iam building my first pc and am sorting out which parts i need, already purchased a nzxt h7 flow 2024 case but it only comes with 3 front fans so i was wondering what fans i need to add or do i need to replace the ones it comes with,thanks.

Just buy a single F120Q Airflow Fan

What case fans you need is largely dependent on what component coolers' fans are used.
Often case front intake fans are all that is needed.
Tell us what motherboard, CPU & CPU cooler and GPU & GPU cooler you are using.

This is what the case can support if it helps.

Fan mounts: 3x 120mm/140mm front, 3x 120mm/2x 140mm roof, 1x 120mm/140mm rear, 3x 120mm floor.

So if you have the x3 120mm fronts I'd say you want to balance that with some exhaust fans. Perhaps go with x120mm rear and X2 140mm on top.

Mixing up fan sizes also helps with any unwanted harmonics especially if you run them all at the same speed.

Then just decide if you want argb or not I guess.

When looking at fans look for a good balance between noise (dB), airflow (Cfm) and static pressure (mm H2O). Static pressure is useful if having to push air through restrictive mesh, radiators, CPU coolers, etc.

whats a good quiet 140mm fan for the rear exhaust. and is it worth swapping the front 3x120mm that comes with the case for 3x140mm.

just found out the fans included in my nzxt flow h7 2024 case are 3 pin ones.

I would get some arctic p12 pwn pst or p14 the pst versions can link together so you just use a single header and set a custom fan curve to limit noise

You can get 5 multi pack for £27 or £6 each

thanks will have a look at them

the arctic fans look good, they seem suitable for the front and top and bottom but i think i need a 140mm for the rear as exhaust any thoughts.

Arctic fans are very good value for money, but one thing I would say about them, the P140s and P120s (not sure if this is still true, they may have updated them in the last few years) do have some motor resonance around 850-1000rpm ...which I have always found annoying, you can get around it by using a fan step-up rather than a curve, if the case isn't on your desk you'ed never likely hear it anyway so doesn't matter but if it is right next to you, just bear this in mind.
