Fan Configuration?

iSteven_6s · July 26, 2020

Slightly longer question so bear with me here...
The cooler I have right now is a Scythe Fuma 2 with the front fan replaced with a Corsair LL120.
My plan is to add two more fans to my system (Noctua Redux). The two configurations I can use are:
A NF-P12 (120mm 1700) RPM replacing the middle fan on my cooler (Scythe Kaze Flex 1200RPM), and a NF-14s (140mm 1500RPM) as an intake fan. (Noctua fan is roughly 40% better than the Scythe)
Or
Keep the Scythe fan where it is, get two NF-14s (140mm 1500RPM) fans and use them both as intake.
(The other two fans in my system are a Corsair LL120 and a Scythe Kaze Flex Slim, both as exhaust.)
Which configuration would give me better cooling?

What the current case and fan setup there is? If you will use same fans and all of them, it matters very little which way you place them. Placing more powerful fans on CPU cooler means lower CPU temps, placing them on case might mean lower temps for both CPU and GPU.

As long as the airflow isn't adequate he could put any number of fans on the cooler, it wouldn't make a difference.

I'd recommend using the cpu cooler with the stock fans, 2 corsairs as exhaust and 2 140mms as intake (in a case without extremely restrictive front panel).

If you did end up buying the 280x, I think the bottom fan positions would be more beneficial (unless you have it on a carpet). With a bottom> top airflow the only "danger" is a hot air pocket above the gpu, but I think the aircooler would do a good job at stirring up that area.

If you have some other case with a restrictive front the 120mm corsair might do a better job at pulling air inside, since 120s tend to have better pressure.
