The average cost of a CPU fan will vary depending on which country one is buying from. In the United States the cost of a CPU is usually between $8 and $30.
Make sure the CPU fan is functioning properly and that the case fan is also operational. If your CPU doesn't have a fan, purchase and install a heat sink and fan that will fit your CPU.
CPU fan is attached together with a heat sink on the mother board, CPU fan is used to prevent overheating of the processor on the motheboard
The fan will work - but it will spin constantly - as it would have no data to rely on to regulate the temperature of the CPU.

What does the CPU Fan connect to?
Neither, The CPU is the Central Processing Unit, it only processes information and bits of data the computer sends thru it. The motherboard supplies power to the case fan AND the CPU fan, which is supplied power from the PSU (power supply unit)
Computer cooling fan
on motherboards it a port that allows a fan to connect to it to cool a CPU/ Northbridge heatsink in bios PC health menu it registers the speed of fan to make sure the CPU ain't to hot and fan spinning maximum speed
This message is generated by your motherboard's BIOS. The alert is referring to your CPU Cooler's fan which is located towards the top of your motherboard. There could be a smaller fan located in the middle section of your motherboard but that is your Northbridge chipset. It’s also possible someone has plugged in a case fan into your CPU fan header (the power plug for your CPU fan) so be sure to check your case fans as well.
The CPU heatsink, then thermal paste and the CPU itself.
Most heat is dispersed from the CPU by the heat sink - a large aluminium blob stuck onto the actual CPU. The fan is there to assist in the distribution of heat away from the CPU and into the surrounding atmosphere. So CPU's run so cool - laptops, phones etc, don't have a fan as the CPU's run relatively cool, and the heat generated can be dispersed by convection.
With a heat sink and fan.
