Peace be upon you, I have 4 fans from Lian Li company. I removed them from a ready-made case, and they are very clean and guaranteed. • Size: 120mm. • Speed: 200 - 1800 RPM (powerful and quiet cooling). • Lighting: Transparent blades support RGB. • One output unit and the rest are input. • Condition: Unused even once. Selling all 4 together, negotiable. Shipping via Redbox for 25 SAR available.
