i was playing a game suddenly was shocked when i heard so much noise from my cpu fan, it was spinning so fast. lasted about 20 seconds. when i pressed alt+tab it stopped alr. what might be the problem? wow it happened again while i was typing this. when i checked the temperature on speccy, it showed only 58 degree celsius. i read that as long as below 80 degree celsius it will be fine.
cpu fan suddenly started making so much noise for about 20 sec.

Fans that you have on a cpu cooler use two sorts of bearings.
With a cheap fan the fan it`s self will contain what we call a bush, the bush is a simple bearing.
But when the bush becomes worn if the fan is a year old or more, due to the rotation of the fan stork that passes down the middle of the Bush bearing, the copper bush wears and becomes oval in shape, where it should be perfectly round on the inner side where the stork of the fan sits.
This causes the stork to vibrate, and will give off a rather loud grinding type sound when the fan is working.
It can be cured by adding lubrication fluid such as silicone grease, and dismantling the fan assembly packing and lubricating the inside of the copper bush.
But to be honest it is more easy just to buy a replacement fan, or a new cpu cooler Vicnes.
If you wanted to buy just a fan then look for one that states it has a dual ball bearing setup.
A ball bearing fan will last up to two to three times longer and will be slightly more quiet in operation.

I see. thought i dont think that is the problem. i feel is something wrong with the temperature sensor for the fan since it only happens randomly and goes back to normal after some time but i dont know where is the sensor.The thing is this pc is old already so im not planning to change things. I can't open some of the screws too. its like rust alr and stuck there. i don't have a casing for the motherboard too, spoiled lots of time already.All i did was to open all the things and reassemble back and it always works back.What do you think about changing the connector? i saw beside the CFAN1 thr is SFAN1 and SFAN2. the fan is currently connected to CFAN1. I plan to buy a new pc on April next year only.

You might need to reseat the heatsink, with some new thermal paste. If the cooler is going bad, you may need to buy a new one. What are the system specs, for this system?
