Question about IBM ThinkCentre S50 8183 - P4 3 GHz (8183D9U) PC Desktop
As fans with ball bearings in them operate, they gather dust. this dries out the lubricant in the bearings track. normally cleaning the fan would suffice to restore effectiveness just run a vacuum over the fan on a regular basis to stop the dust building up.
if you have added lubricant to the bearings you may find that more dust is now sticking to the dust that was already there reducing the fans effectiveness even more and causing more noise.
another possible reason for the increased noise is that when lubricating the fan, depending on how you did it, you may possibly have bent the fan's axle slightly again increasing vibration and noise.
personally I think it unwise to add lubricant to a ball bearing track such as that on a cpu fan as lubricants vary in viscosity and suitability for use and I wouldn't know which one to buy. If the axle has become bent, I believe it is possible to have it straightened but with the price of fans being so low I feel your best course of action would be to replace the fan and then make sure that your new fan doesn't get clogged.
