Statistically, fans are not the most failing things on PC, but they have a failure rate of 0.96% (compared to the failing part, motherboards, with 1.90%). There are a number of reasons why they might break down, but they are usually related to why your rotor has reached the end of its useful life; constantly changing you can wear something on the bells and the time comes when he no longer gives up.
How much does it cost to repair a PC fan?
That means, the main point of failure of the fan failure is the driver of the vehicle or its bearing. If the problem arises from the latter, it's not difficult to find bearings that can be used to replace those from the factory, as well as less oil to lubricate, but the problem lies in the difficulty of removing normal holes and replacing them
If the fan has ball bearings that can be repaired, but in order to remove them we will have to completely separate the car and remove it, risking doing so because the plastic that lays them can break or explode. If the fan is not the type to carry, then a fix is issued.
If the problem for fans is due to a car that stopped working, it could be remedied by replacing it, but here the difficulty would be to find the maximum, amperage and speed that suited the follower, an almost impossible task.
Finally, if the fan has stopped working because the stain (or several) have been broken or cracked, you can discard it directly. It's not worth it or you're trying to attach it because you never get the same look, and any of your exits will keep the follower from rotating in the same way, producing a lot of noise and the risk that the sticky stain will fly.
So is it always better to buy a new one?
Considering the head care and difficulty trying to repair the fan, the recommendation is that yes, it is always best to dispose of it once it has stopped working and to buy new ones. Even if you do not have a lot of money to invest in a good fan, there are 6 good euros that will provide you with good service and will last for many years.
It's not worth trying to fix a PC fan, especially considering the cost. You can get cheap fans for around 5-6 euros easily at stores like Amazon, and even the top-rated fans will cost you at least 30 euros.
