There is no set standard, especially for laptop coolers. They come in a wide array.
Generally though, the smaller the fan the higher the RPM. On a relatively quiet desktop the CPU fan is gonna spin anywhere between 2500-3500RPM. A smaller fan like those seen on some laptops might spin at about 5000+ RPM.
Yet, laptops also have a wider array of fan controllers than desktops too...so again, its hard to pin down whether or not yours is malfunctioning or working just fine.
As long as you can feel airflow hit your hand, you should be fine. The primary catalyst for overheating on a laptop is usually the heatsink itself. Mostly being dust accumulation which is especially hard on laptops due to the already confined space. Laptops that are several years old also might start having problems due to deteriation of the thermal pad or thermal grease between the heatsink and CPU itself.
