The cost of a CPU fan for a laptop can vary significantly depending on several factors. Brand is one of the key determinants. Well-known and reliable brands often charge a bit more due to their reputation for quality and performance. For example, a high-quality laptop CPU fan from a popular brand like Dell or HP might range from $20 to $50. Cheaper generic or off-brand fans can be found in the market for around $10 to $20, but their durability and efficiency might be questionable.

The type of laptop also matters. Ultrabooks and thin-and-light laptops usually have more specialized and compact CPU fans that can be relatively more expensive. These fans are designed to fit into the limited space while still providing adequate cooling. A fan for a gaming laptop, on the other hand, may need to handle higher heat loads and could cost more, typically in the range of $30 to $60. Additionally, if you opt for an original equipment manufacturer (OEM) fan directly from the laptop manufacturer, it could be on the higher end of the price spectrum. However, OEM fans are often designed to fit perfectly and work optimally with your specific laptop model, ensuring better compatibility and performance.
