After cleaning my fans when I switch on the PC I see this CPU Fan Error! Press F1 to resume (this screenshot is similar to what I see View: https://i.imgur.com/uiKD57s.png
) I pressed F1 and I can continue to load into Windows 10

During cleaning I accidentally slightly wriggled the coolermaster metal fins (beside the black fan) on the CPU.

Fan noise now is noisier than before cleaning.

Q1. What shall I do now? Are my fans still operating correctly? If I switch off my PC now will I be able to switch on my PC next time?

Q2. Is the black fan beside the metal fins operating correctly?

Q3. The white fan (back fan) seems rotating slow or is that normal? If I remember correctly the white fan used to spin faster and produce bigger wind.

Q4. I have accidentally slightly wriggled the coolermaster metal fins during cleaning of the fan, would the CPU thermal paste still be in good condition? I am afraid the thermal paste is detached when I wriggle and cause CPU temperature to rise.

The back fan is noisy. I am using back fan Arctic F12. Can I replace it with Arctic F12 PWM? It is hard to get without PWM version, can my motherboard accept Arctic F12 PWM? If I leave everything as default is it the Arctic F12 PWM will be at highest speed?

If I unplug my non pwm fan now, and plug in a new pwm fan, the new pwm fan connector will be at the exact same connector on the motherboard correct? Then if I do not go into the BIOS to change anything does it mean I will be using the new pwm at highest speed by default?

My motherboard https://www.asus.com/SupportOnly/P7P55DE_PRO/HelpDesk_Knowledge/

I do not want to mess with BIOS, I do not know anything about PWM, getting PWM version because no stock for normal non PWM version.

The noise happens at random times and lasts for about 5mins then disappears and maybe quiet for a few hours and noise appears again for about 5mins. Is this kind of pattern a faulty bearing?

I did not hold the blade while cleaning, I used the cotton q-tips to wipe the blade, could it be my movement destroyed the bearings?

The fan was normal quiet before I cleaned the fan, so I am sure it is the cleaning movement that causes the fan noise, my mistake to clean the fan by touching it, I think next time I should use a can of air to blow away the fan dust to ensure my fan will not be destroyed while cleaning, is a can of air safer to clean the fan since nothing touches the fan?

Thanks
