Chucked this fan in my track-prepped Evo and it’s been mint from day one. Temps stay rock solid even after long sessions at Ruapuna. Easily the best cooling upgrade I’ve bolted on.

Running this in my drift S13 and it hasn’t missed a beat. Used to battle with heat soak but this SPAL keeps everything controlled even during back-to-back runs. Proper quality gear.
