Vintage UV fans from the casemod era. Strong and functional (still spin fast), but some of them have UV LEDs that are spoilt (see photos). The green/blue one doesn't have any working LEDs so there's no photo of that one. All are 3-pin header type. All at $3 each regardless of LED condition since UV remains reactive to UV light regardless of age. 1 day no-spin warranty for peace of mind. (I guarantee it will spin when you plug it in)
