Hey
I finished my Q300L build some days ago.
I have:
CPU: i5-8400
GPU: sapphire Vega 56 pulse
AIO: Eisbaer 120 lt
Fans:
2x fans in push/pull config
1x NF-P12 redux-1700 top mount
The right picture was the first fan setup i did.
I had Problems with thermal throttling of the PSU, quite toasty Temps overall.
I changed the settup like shown on the left pic. My themps at the moment are ~60°C CPU and ~62°C GPU (~25°C Room) after 2 hours of PUBG. (med to Ultra, 1080p)
I ordert three more NF-P12 redux-1700 the setup will look like so:
I will Post my Temperatures when im done.
Edit: The Temperatures with the setup above (without the optional fan) are after
2 hours of PUBG 1080p, Ultra preset, screen scaling 110: Max Temp. CPU: ~62°C GPU: 57°C
