17 R5, CPU fan noise after cleaning

If the fans were loud to begin with, the bearings are worn.  The only solution is to replace the fan(s).

Yea, but the temprature was fine and they werent like super loud and i thought that cleaning them would imrpove the performance as well, but after that the cpu fan is not just loud its making a screech sound , so do you think the fan is damaged or maybe some dust are between the bearings?

I think i will have to replace it then, i want to know if its alright if i dissconnect the fan and rely on my external cooling pad(while monitoring it) until i get an another fan, also what are the consquences if i let the fan run even if its malifunctioning, can it cause any problems aside from the temprature rising?. Also do you where i can order another fan?. I bought this laptop from the usa and i live in egypt now and i cant find it in the laptop parts when i check with the service tag. Thanks you.

It doesn't take much dust to cause an imbalance in a rotating fan - and damage the bearing.  The bearings aren't serviceable;  if they're noisy, the fan needs to be replaced (resist the urge to lubricate the fan, which will exacerbate the dust accumulation problem and possibly sling oil droplets all over the system).

Here’s the CPU fan and GPU can replacement:

If the fan is still spinning and you can endure the noise level, leave it in place.  If it's not spinning -- or the noise is too  shrill to take -- stop using the system until you get a replacement.

To prevent further damage to the system. You need to shut down the system and make sure to put it in a safe area.
