hi so im runing 3 fans that came with my pc those are super loud thinking of replacing them with full noctua
i have 2 noctua fans on top one blowing intake 1 outake for the cpu it never gets over 40's under gaming
1 fan exhaust

Part of the gpu issue is the top fan. You have a Noctua in top blowing air downwards. The gpu exhaust wants to go up. While you might get slightly better cpu temps with such a close source of air, the balance is off and gpu suffers.

I'd block off the top intake totally, no fan, no vent. Just rear exhaust and top-rear exhaust. See how temps do then.

i drew a quick pic
it shows front fans normal
the real deal is tops fans 2 exhuast right because!
one top fan if exhaust will just blow out the fresh air coming from front fans ALSO the cpu cooler kinda blocks air flow so one side intake one side exhaust
do you get what i mean?
what do u think about that good?
