Fans are generally inexpensive, although 140mm variants obviously cost more than their 80mm counterparts. However, they do pack a lot more punch and are suited to large, high-end builds. One thing to keep in mind is that you’re not likely to buy just one fan. Modern cases often accommodate up to six and depending on how much cooling you’re interested in, you may find yourself spending more just to get several fans at once.
To give you a better idea of how much money you need to reserve in your budget, we’ve prepared a little rundown of approximate pricing for 140mm case fans.
Low-end 140mm case fan – $10-15
Mid-end 140mm case fan – $15-25
High-end 140mm case fan – $30-50+
