NOCTUA NF-A9X14
At last a 92x92x14mm fan that's slim, efficient and quiet.
I lost around 4°C in processor temperature (81°C instead of 85°C in intensive testing) by attaching it to the side panel of my PC case (Chieftec HO-12B-OP case / AMD Ryzen 5700G Cezanne processor / ASUS TUF GAMING B550M-PLUS WI-FI II motherboard / Noctua NH-U9S radiator-fan / Noctua NF-A9 PWM fan at the back of the case).
