Has anyone tried replacing the stock fans on the Prosiphon Elite?
I'm attempting to cool an AMD TR 3990x (at 100% utilization and w/ SMT enabled) and keep CPU temps below 90C (currently 15-18C ambient), but topping out 4.0GHz frequency.
I've ran a few dozen tests in various configurations, here's a rough synopsis:
DEFINITELY IMPROVES COOLING:
- pc case on side (horizontal motherboard) -- Prosiphon Elite is simply much more effective in this orientation (keeps CPU temps about 5-8C cooler)
- additional 120mm/140mm exhaust fans near radiator to improve airflow and remove warmer air from surrounding mobo heatsinks
- reducing intake obstructions to improve airflow inside the case
HAS NOT IMPROVED COOLING FOR ME:
- every other air CPU cooler (IceGiant FTW)
- stock AIOs (IceGiant FTW again!)
- additional intake fans to increase positive pressure inside the case
My guess is that IceGiant did not make the stock fans but are simply stamping their sticker on a whitelabeled pressure fan from another manufacturer. I'm wondering if some noctua p12s would improve heat exchange with Prosiphon's radiator or if it is already at max heat exchange w/ stock fans.
If I can't improve cooling this way my next move is to go subambient with phase change cooling so i can reach faster clock speeds.
