A very warm welcome to the HP community. A very good day to you. 

I understand that you have an HP TouchSmart 300 series PC and the CPU fan does not spin by itself. You have to manually push it to make it work. 

I would like to know the following information to assist you better:

• Please let me know the exact product model no. This link will help you to find the model no: http://hp.care/2bygf7l

This normally happens if there is dust accumulated in the fan. I suggest you to perform the following steps to isolate the issue and arrive at a fix.

• Shutdown down the PC.
• Disconnect all devices and cables (including power cable) from the PC.
• Press and hold the power button of the PC for 10 seconds. 
• Reconnect the devices and the power cable.
• Power on the PC.

If the fan continues to not spin by itself then you may try to clean the air vents and fan with powered vacuum to remove dust. You may refer to this link. 

I sincerely hope this fixes the issue. Please feel free to let me know how it goes. All the best! 🙂

If I put in another position the propeller, it works. No,  everything is clean. My problem is, the fan is not good or the motherboard ?

Thank you.

You're welcome. 🙂

The evidence indicates that the motherboard is fine and the issue lies with the fan. Because if the motherboard had a problem then there would be other results. 

I suggest you to reach out to our HP phone support to explore the hardware service options for your HP PC. 

Please do keep me posted for any further questions. All the best! 🙂
