Super glue it!
I use ATM oil as I said, it works perfectly

Re: Computer fan noise and maintenance

I tend not to use oils. They will always run off or evaporate. For the long haul, a good grease is the only way.

Re: Computer fan noise and maintenance

I can not find the blade at all.

Tho it was a cheap fan anyway. [price 2.58$]

Re: Computer fan noise and maintenance

Lol, my fans, have had that oil for one year, it's still there, working ok

Re: Computer fan noise and maintenance

I have bought fans for 80 cents, and those have lasted a while(5/6 years)

I'm waiting for the fans at HSC to go on sale again.

Some people swear by oil, others by grease.
I think it really depends on what kind of grease/oil one uses and also the quality.

For grease, I would NEVER use regular grease, as that is the stuff that dries rather very quickly. Good quality Lithium grease (the white stuff typically used on gears), on the other hand, could probably be used and wouldn't not dry in a very long time.

So I think it really depends on the quality and type of grease/oil used.

I personally have cheap fans that are over 10 years old that I oiled with regular engine oil, and they still work fine to this day (no, not in 24/7 operation, as I don't run any of my computers 24/7). The oil in them is not dry yet - I've checked recently.

Is it possible to fix the clicking sound that's coming from one of my fans.

Re: Computer fan noise and maintenance

If it's a ball bearing fan, then probably not. I have a BB CPU fan that does it and even after I put oil in the bearing, it still does. Also have two other fans with BB, and they are noisy simply because the bearings are very worn - nothing that can be fixed with oil or grease. They just need new bearings.

On the other hand, if your fan is sleeve bearing, then YES, lubing the fan should stop that noise. If the noise persists, you need to fully take apart the fan and clean the sleeve bearing, then put oil or grease in it (again, this will depend on preferences here), then close it back together.

Re: Computer fan noise and maintenance

How can i tell of it's a ball bearing fan or a sleeve bearing fan?
With the fan i have the casing is transparent so i can see the motor inside. I can take photos if you need any.

Re: Computer fan noise and maintenance

Probably a sleeve bearing, put a bit of oil and see if it is quieter.

Re: Computer fan noise and maintenance

What type/brand should i use?
This is my first time doing this.

Re: Computer fan noise and maintenance

I use ATF oil or motor oil two drops and it should be a bit more silent, is not going to be like new but it will be better

Well, it certainly is nice when you have that option.

I had to fix two small fans today - 40 and 50 mm. Both are ball-bearing fans with very noisy and dry bearings. They both spun fine, but the noise they made was terrible. A few drops of oil made them a lot more quiet. Definitely not perfect, but much better than before.

Yes, I can buy cheap replacement fans on eBay, but it would take forever for them to get here and who knows how long they will last. And if I were to buy high-quality fans, that would probably cost more than what the video card and the motherboard these came out of are worth.

So sometimes you have to work with what you have on hand and do your best to fix it right.

Re: Computer fan noise and maintenance

Just fixed and industrial fan with sleeve bearing,
The grease was dry and that made the fan spun sloooooooow, disassemble it cleaned the grease put ATF oil and like new, it didn't have much use so no damages on the bearing

Re: Computer fan noise and maintenance

Do i have to open up the fan to put oil in?

And the blue LED fan i have looks like it had oil/grease in it but it looks like it all dried up.
