A fan I made for a project of mine, it works for both Eevee and Cycles perfectly. The material is Procedural so it's easily adjustable when it comes to color, distortion, roughness, details, normal bumps. It does add to your photorealistic render/scene. Hope you enjoy it, I'll keep on uploading models including Free and Paid ones, download every free one, I put a lot of time on them so they'll be very detailed and proccessed.
Please like the model if you find it helpful for your project
