I tried fixing my psu this way and it shocked me. I had a stroke and am unable to talk properly now. But my psu is working. Thank you
Glad it helped
i really hope this was a joke comment lol
@@plasmodius9449 I wish it was
@@KuhmKnight bro are u ok??????
@@Arcticretro dude he literally got shocked
I oiled the fan just like you did, and now my PC is silent. Thank you! :)
Types of oil ?
I need to do this, my pc power unit is annoying
@@Northale did you fix it? I really dont want to remove my power supply fan because im afraid of being shocked
@@Im_SSJay me too 🤣
update?
Wow. I love the fact that showed all the mistakes and also showed where you thought there was a screw under the sticker and there wasnt and also where you made the fan hit the cove. Very good video.
Do this with care. I also wouldn't recommend open up your Power supply.
They have high voltage Capacitor in it that hold up charge for very long time that easily kill a human.
Yes, I know :)
Once, I swapped the fan in my PSU for some quiet fan I had laying around, my computer got SIGNIFICANTLY quieter.
When it was stock, the damn computer sounded like an server, despite being a regular rejected PC. Once, I even accidentally wired up the new power supply fan incorrectly, and yet the power supply got through a system software update without shutting down!
Unfortunately, if I want to get an even quieter experience, I'd have to replace the CPU cooler, as it makes about 90% of the remaining noise. The case is also really cheap, so resonance heaven.
Also, you can discharge the high voltage capacitors by either powering on the system while unplugged, or shorting the green wire with any of the black ones.
you've inspired me to not mess with the power supply
5:34 upon reaching this part I have realized I am totally okay with my psu currently
Thx bro it worked mine was louder than a jet engine
Very well done vid.. im gonna try this myself
did it work???
@@alouec9807 its been 2 years he's definitely died doing it.
Let me do it this weekend, thank you.
It was a good fix :)

What oil and lube you use for that noisy fan? Can i just use 1 type of it?
Great video. Kinda unrelated but you sound just like Jens Stoltenberg :D I keep imagining you saying "We will not tolerate Russia's nuclear sabre-rattling".
Haha, yes, Norwegian-English is like that. Never learnt the pronunciation properly :)
@@Arcticretro haha I see! Honestly I kinda like it. Somehow makes people sound even more intelligent!
Hopefully, mine is just the fan too... I was quietly chilling on my Arabian horse in RDR2 when this shit happened. It's driving me mad.
My pc does this noise quite often when I boot it, but it gets quiet after 3-5 minutes. So I was wondering what I should do to fix this, I guess I try to open the psu and clean it.
I have a year old PSU. It is top of the line gold rated. The coil whine from it is so loud lately. Could it be filled with dust? Is it not enuff watts now that I upgraded my GPU?
If you want to check wattage compatibility you can put all of your components into PC Part Picker which will give you a wattage requirement minimum. As a general rule you want an extra 100 to 200 watts over what it tells you. You need a little head room on the wattage.
Also these days a Gold ratting really does not mean anything as very few PSUs are under Gold. The Gold rating system is just about how efficient they are but not what is actually in them.
80+ = 80% efficiency at 100% load; 82% at 50% (working) load
80+ Gold = 87% efficiency at 100% load; 89% at 50% (working) load
80+ Titanium = 90% efficiency at 100% load; 94% at 50% (working) load
Now you have to check the PC Cultist PSU tier list. There are some expensive PSUs low on their list and there are some cheap ones high on their list. They sort everything on their list by components used, output options, true efficiency under realistic loads, build quality, and life span. If it is not on their list though it does not mean it is bad just that they have not tested it yet, and if it is an older unit they likely never will. That said if yours is only about a year old it should be on the list.
What was that clear plastic piece covering about half the fan's intake/exhaust area? I've not seen that feature before.
Others have mentioned the method for bleeding off stored voltages in an AT/ATX power supply unit: press and hold the power button on the system with the power cord disconnected. The power LED should light briefly, then fade out. The unit should now be safe to work on, but make sure (put a tester or a meter on it).
Lubricating a fan is different for each fan encountered. If you're in a situation and need to quiet the fan NOW, use of some silicone-based machine oil (like 3-in-1 Silicone) will help. With any oil, use sparingly. Excess oil migrating from the fan will make a mess inside the PSU and cause dust to adhere to it. I'm presuming this is why Tom followed oil with contact cleaner, to remove any excess.
The best path forward is to replace the fan. Depending on the PSU design, this may not be a simple task. Please bring the work to a qualified technician if you are not sure how to do this work safely. Selection of the new fan should be done AFTER examining the old one to determine correct supply voltages, presence of any "smart" sensors, etc.

My PC looks affully like yours, will do this tomorrow
it's like crazy Russian hacker.. only another cool guy
Superb video. Mange tak. Hvor er du fra I Norge? Bodo? Tromso? Trondheim?
Bodø
I did it with food oil :) The noise is gone :)
i find myself doing this at least every month. is that normal? seems like it will always go back to that grinding noise. but with just adding a bit of oil it will quiet it down just momentarily. is there a better solution? or is it normal to often add oil on that part?
No it's not normal. In fact it's not normal to open your power supply.
You realize that is a rubber cap you can remove under the sticker ?
DO SOME CABLE MANAGEMENT
Is this one of those fake videos! You killed your fan or you forgot to plug it. Right?
If the fan is turning then, it's a hell of a fix.
My psu is making a very similar noise. I'm not willing to attempt to fix a psu myself, but until I'm able to get it fixed/replaced (undecided yet) how safe is it to use?
Not sure. Probably the bearing is worn. Should not be a problem
@@Arcticretro I'm thinking it's a bearing. If it wasn't on the psu, I'd give it a go. But better safe than sorry
Same i dont want to shock myself, is there any trusted place to get it fixed?
@@Im_SSJay Geek Squad or Best Buy should be able to help you. Be careful going through search results to avoid tech support scams.
I though it was about an electrically noisy power supply, not acoustically noisy.
-Note to self.
Yeah don’t punch the tempered glass at full force, maybe try fixing your pc normally.
Are you okay lmao
Why i am scared to do this
i cant do it alone if no one helped me my psu on 10 year pc has exact same sound from start of vid when me and mom tried to clean it last time it was hard to put back together
Whenever I turn on my pc power supply it gives a noisy sound and I thought it's broken
Solution?
Hello bro its ok the fan of my power supply is noise?
10000000000% Swedish xD
i use cook oil and my pc is not working rn :/ :D
Try to cook some kitchen on top of your psu?
DO NOT DO THIS. DO NOT OPEN YOUR POWER SUPPLY. IT CAN SHOCK YOU VERY BADLY. Also you hear his accent. He's Russian. He he'll be ok.
Obviously it is now powered on. And the capasitors are drained
I'm Norwegian. No danger at all
@@Arcticretro that's not explained. So people will just pop it out and open it
i had a rattle for around 3 mins so i came to watch this video if the noise comes back its a sign that i need a bigger psu and an excuse to buy a better graphics card
Just buy a new fan in aliexpress and replace it lol
Of course, but then the video would be shorter:)
