NOCTUA L12 GHOST
(120MM FAN EDITION)
The Noctua NH-L12 Ghost S1 Edition is 66mm tall low profile cooler with included 92x25mm fan. The L12 Ghost Edition heatsink is based on original L12 design and not the newer L12S. Using 120mm slim fan under the L12 GE provided substantial performance improvement.

FANS
The L12 Ghost Edition comes included with 92x25mm fan. Unfortunately for whatever reason this configuration isn't very effective for cooling AM5 CPU's based on our testing. Squeezing 120x15mm fan under the heatsink is another story providing very respectable thermal performance. This does require low profile 33mm tall ram to work. We found SilverStone AS120 (paid link) works well on this configuration.
TEST SYSTEM
Testing is carried out on the BC1 Mini (open testbench) in 23°C ambient room temperature.
THERMAL BENCHMARKS
We compared Noctua L12 Ghost Edition with 120mm slim fan against the Noctua L12S
FINAL THOUGHTS
We originally tested the Noctua L12 Ghost Edition using stock 92x25mm fan on AM5 and performance was quite underwhelming for this cooler size. I’ve never really known what to make of the L12 Ghost Edition as the thermal numbers didn’t make much sense on AM5. Using a 120mm slim fan really is a saving grace and might be my go-to cooler along with L12S in future builds. You can find our full thermal benchmark charts here and see where the L12 GE (120mm fan) roughly fits in. We’ll add the L12 GE 120mm fan configuration at later date.
