How to fix fan rattle/noisy fans

[@zakariazaouia2060]

My fan was noisy for almost a year now, and the noise got worst lately. Was gonna buy a new one and then I came across your video and it worked!! Thank you sir!

[@KNTech]

Hey Zak, glad it worked for you, its a simple fix but an effective one

While this does seem like good advice, it isn't because he doesn't tell you what you should do after flushing it out with WD-40. Regular WD-40 is not a lubricant despite appearing like one when it's first applied. WD-40 is meant for displacing water and flushing debris/dust out of things. It isn't meant to stay in as a lubricant for something spinning at such high RPMs as a fan. Flushing with WD-40 also flushes out most of the machine-grade oil applied at the factory. WD-40 by itself will, rather quickly in comparison to oil, take on a more resin-like consistency, which will have that rattle coming back with the added benefit of putting more stress on your fans by making them work harder to spin. You're supposed to follow up a WD-40 flushing with actual machine-grade oil based on your needs. For PC fans, just a light machine-grade oil is enough to keep them spinning for years. Well, outside of any needs to flush them out again. There are also WD-40 brand lubricants that you can buy that are different from just regular WD-40.

[@KNTech]

Hi, thanks for the comment, I did mention (3:10) that light machine oil can be used, but thanks for clearing up any confusion anyone was having

[@CFDFirepup]

Had 2 out of 3 Diablotek cheapie POS fans making noise in my Powerspec G433. I was ready to replace the fans but decided to watch your video and then I gave it at try. 45 minutes later my PC is running quiet as brand new. I'll eventually replace them with better fans as well as the SoHoo GameMax controller card, but for now this really helps. Thank You so much for the video.

[@mrpearpl2847]

Can you please tell exactly in which part of the fan should I apply the oil. Is it the part where the lubricant was pre applied before ?

[@DonutSurfingTheInternet]

Very insightful video. It has been a very long time since I last built a computer so I am out of touch on a lot of things, fans included. Based on this video, I'd be happy to perform that sorta maintenance on my own fans if they needed it. Thank you for the video! Lookin' forward to the next one!

I have the exact same fans and they started this same issue around 2 years after i got em. Guys at the comp store said i had to switch em out. This helps me save a few bucks for a while, thanks!

[@KNTech]

Mine are still going strong and its been about 8 months of use since i did it, might keep you going for a while longer.

[@mtbboy1993]

Sometimes the fan has just dislocated, if so carefully pull the fan out. Other issues, inspect fan for cracks. Also cheap fans can have ball bearings, those eventually will make noise. You have magnetic bearing, they will be quiet usually until they misalign. But maybe lubing those helps, but impossible to tell if you lubing it or you you moving the fans fixed it. Just flipping the fans upside down might fix it. But maybe lube will reduce noise anyway.

[@PatrickStar19872]

how long does this last till it starts to rattle again, I read somewhere a while ago that WD-40 as it is a water dispensor evaporates over time so after a couple months the noise will come back

[@KNTech]

Hi There, mine are still good still. it does evaporate but leaves behind an oily residue. If you can find a light machine oil that would work better, but mine are still going strong

[@The_Real_Indiana_Joe]

I had a rattle in my fans, I turned the off one by one, but it wouldn't stop. I finally figured out that I need the outflow fans (only two) to be at a higher RPM that the intake fans (there are three). Once I slightly increased the RPMs the noise stopped.

[@KNTech]

Glad you got it sorted, The usual way to set fan speeds (assuming you have the same number of intake as exhaust/outflow) is to have the intake slightly higher RPM than the exhaust, that way you has a slight positive pressure in the case which makes it harder for dust to get in when it running.

[@christianbiliran8002]

is it safe to use WD-40 for lubricating? or which oil is best? thanks!

[@KNTech]

Hi Christian, WD-40 will do ok, a light machine oil would be better, but can sometime be harder to get hold of. That said my fans are still going strong in another PC after i swapped them out

[@KNTech]

HI there. i assume you removed the sticker and looked underneath? most have either a small area that will take the lubricant, or a plug you have to remove. If you cant get to the bearing then this fix wont work for you, sorry bud

[@YoYoDancesOnYou]

Hey! I have the skytech blaze 2 and one of the fans have started to make somewhat of a noise like yours. I think it is coming from my cpu cooler other then the other fans. What do you recommend I do?

[@KNTech]

Hi there, looks like you are running a Ryzen CPU. I haven't tried this fix on CPU fans. in your case you should be able to get a wraith cooler online fairly cheaply. If you do try and fix the one you have be very careful as running the CPU without a cooler for more than a few seconds could damage it. Good Luck

[@YoYoDancesOnYou]

@@KNTech Thank you for the response! I would just like to know if a rattling sound is also very bad for the system and if it should be something i should be worried about.

[@KNTech]

@@YoYoDancesOnYou Obviously if its rattling then something isn't fitting correctly, but i would let the temps of your CPU tell you what you need to know. If it starts running hot then you should change the cooler. Maybe run a benchmark, something like Cinebench every 6 months and monitor the temps, if they don't go up significantly then you should be ok. But as always, just keep an eye on anything odd

[@dogcreek-customs5168]

Although it works WD-40 is not a lubercant WD stands for water displacement the 40 is how many attempts it took to create the formula. 3 in one is best.

[@KNTech]

You are absolutely right, i only used as i didn't have any light machine oil, but for sure that is better. WD-40 does in fact evaporate leaving an oily residue, which does lubricate a little, but not as good as 3in1

sounds like a tricky one, if you can, try changing which fan header on the motherboard the fans are plugged into. Also a BIOS update might help, but only try one thing at a time that way you will know which it was that worked. Good luck

@@KNTech I installed x3 new cooler master sickleflow 120 fans, it turns out with these “sealed bearing” fans there’s no way to apply a small amount of lubrication from The back under the sticker. But you can (with some force) push the fan blade out of the housing, and you can apply an amount to the inside from there. By the time I realised this I had already installed the new ones haha. Cheers mate

@@KNTech aye hold up brother because before I threw them in the bin, I decided to forcefully remove the fan blade. If you can’t access from the back via sticker removal, you can pull the fan blade completely out of the housing, exposing the internals. I applied a small amount of lubricant to the drive train, pushed the fan blade back in and vola. Kept them as spares.

[@beanboxer6830]

Can a rattling fan damage anything?

[@KNTech]

The rattling is a sign that the bearing is loose/starting to break down, eventually it will completely fail, but by then the noise will get a lot worse, to the point where you will probably replace the fan, so yes eventually, but in reality probably not.

That al depends on where the sound is coming from. If it is from a fan, its a sign of bearing wear, and eventually it will fail, if it is from somewhere else i would definitely investigate it

Nice video ! Could there also be a vibrating noise coming, because the fans are only screwed through one side of the fan ? With a short screw, not a long one, which goes thorught the whole fan ?

[@KNTech]

Hi Zan, very unlikely, the short screws screw into the plastic of the fan frame making a tight grip to the case. i guess its possible, but only slightly, that you may have stripped the thread in the fan frame. if you are getting vibration it is most likely to be a part of the case that does not fit correctly or maybe even some cables that are not tied down. A good starting point would be to take off all the panels on your case first and see if that fixes it, if that doesnt then try unplugging each of you fans one by one. if one of them stops it, take that fan out and run it out of the case. Good luck
