486 Pentium CPU Cooling Fan Socket 3 4 5 7 Legacy Processor Heatsink Fan

486 Pentium CPU Cooling Fan Socket 3 4 5 7 Legacy Processor Heatsink Fan

Generic CPU cooling fans compatible with Socket 3 (486), Socket 4 (1st-generation Pentium 60–66 MHz), Socket 5 (2nd-generation Pentium 75–133 MHz), and Socket 7 (Pentium 75–200 MHz) processors. These small axial fans mount directly to the processor package or a heatsink to keep legacy CPUs within safe operating temperatures. One fan is included per order; the specific style is selected based on available inventory.

Applications

Socket 3, 5, and 7 CPU cooling fans were standard thermal management components in desktop PCs of the early-to-mid 1990s. As Intel's 486 and Pentium processors increased in clock speed — from the original Pentium 60 MHz in 1993 up through the Pentium 200 MHz in 1996 — active cooling became essential. These fans mount directly onto the processor's integrated heat spreader or a clip-on heatsink, drawing air across the fins to dissipate heat generated during operation. Today they are primarily sought by vintage PC enthusiasts, retro computing collectors, and technicians maintaining legacy industrial or embedded systems that still run on Socket 3–7 hardware. The variety of connector types (Molex pass-through, 2-pin, 3-pin) reflects the range of motherboard fan headers and power taps common across that era.
