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!

This was brilliant his intro was so short and simple but straight to the point👌

Good video!! As an avid tinkerer of all things PC and electronic, it’s good to find a new channel that shows useful solutions to problems!! Keep up the good work and I’m looking forward to seeing what’s next!!

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!

3 in1 OiL is the best for a job like this. Do NOT use WD-40 for the bearing shaft.
WD-40 is nor designed for this. It is NOT OIL! The best is Motor OiL 20W50 in a 21 G Syringe Neddle from your local pharmacy, and your done!

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.

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.

Microphone pop at the start of the vid: You might already know this.
Tip use a pop filter or move mic to the side or above your mouth, if it's in the way, turn up the gain, if you can't download EqualizerAPO and boost the mic from there. I had to as mine was too quiet.

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.

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!

If you heat the sticker with a hair dryer, it comes off much easier

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.

My fans coolmaster fans do this and it's so annoying, gonna give this a go

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.

My fan was making noise so I opened my case with the computer on and stuck my finger into the fan
It hurt like hell but it stopped making noise for a second

[PatrickStar]

Beautiful computer, love the white and x3 purple fans.

[martinflaten]

Thanks for the useful video! my pc fan started the exact same rattle today, now im off to buy some WD40 !

I have 2 lasko clip fans... One of them I keep in the kitchen because I use it when the dishwasher is done...I clip it to the counter upside down to blow in the dishwasher to dry the dishes because it works much better than the dry cycle....My question is... when it's in the upside down position, that's when it rattles...if it's upright, it doesn't.... It's whisper quiet if it's upright... is that normal for it to be noisy orientated that way? thanks

i have a gigabyte and there is no poing to open it up sad
