Memory HEATSINK JONSBO NF-2 ARGB, black

The JONSBO NF-2 ARGB is a compact active cooler for RAM modules designed for users who overclock memory or want addressable RGB over their DIMMs. It’s a low-profile heatsink with two 50×50×20 mm fans mounted over an aluminum radiator that secures above the memory sticks to help remove heat from hot ICs.

Fans use a 4‑pin PWM connector for speed control while lighting runs on a 3‑pin 5V ARGB header; speed range is about 600–3600 RPM and noise up to 22.4 dB(A). NF-2 fits builds with ARGB-capable motherboards, small cases and tightly packed layouts around the DIMM area — useful when pushing high-frequency RAM.
