Creality Ender 3 v3 SE | Hot End Fan Fix 

I just got this problem and the damn thing broke 1 day after the machine's guarantee expired lmao, now I gotta go back to the trenches and find a super over the top upgrade that will fix my printer for a LOOOONGGGG time (thanks for the links) UPDATE: I replaced the fans and installed this upgrade (ty for the tutorial) turns out the ceramic liner got melted (apart from the fan) because of the excessive heat and is messing up my prints. If you have this problem as well AFTER doing the whole fan replacement, get yourself a: Ender 3 V3 SE Hotend Kit replacement. They are about 17-18 bucks and will fix any weird heat related problem you get if your heat sink fan died.

I have the same printer and I just started getting that same noise after having the printer for about a month. Your video was the first to pop up. I think i will buy a couple Noctua fans and replace both fans to help make the printer quieter Don't stress about the camera angles, they showed everything we needed to see.

My KE does the same!😂 That little tube I think you heat up and the metal melts and solder the wires together.

fyi, that electrical connector you are using (the clear tube with the white bands towards the ends and the metal in the inside middle) is not a crimp fitting. It's meant to be heated with a heat gun. The metal inside is a low temp solder that will melt and solder the wires and the clear tubing is shrink tubing that will shrink and seal the connection.

Yeah, that fan sounds like it's already worn out. I suggest getting some fans with actual ball bearings. The " hydraulic" bearings don't always work at different angles.

ok so I just want to add my case... I was having some noise and then it became like very bad. First I thought it was the filament guide was broken, but then, after opening the hotted I`ve noticed that the fan was making this noise. I watched this video and was already thinking of purchasing a new one, because everyone was saying "yep, it's gone"... So, since I was going to swap it, I've thought, well maybe I will try to clean it up. If you set the nozzle temp to 50 deg, the fan will start... so I removed the fan from the cooler, and let it run on my hand... for my surprise, it wasn't making any noise... So I've screwed back and set to 50 deg... and the noise started again... so I thought... it has to be the vertical position... I removed again, and ran on my hand vertically... no noise... So I thought... probably the screws... I've added back but only put 2 screws diagonally... and the noise was there... then I've started unscrewing a little bit while running... and the NOISE WAS GONE... So what I think it... the holes are not flat... when you screw too tight, it bends the plastic case of the fan and it starts to scratch somewhere inside. So I would recommend testing this and see how it goes... for me, leaving the diagonal screw not too tight fixed the problem.

Try to look at some rc hobby shops that sell ECS for brushed or brushless motors which have the same size of that small fan.I hope that will work

fan is on backwards EDIT: glad you caught it... Always remember, ugly side blows.

1. got a free replacement from creality. but as soon when this one fails im going to upgrade it all with a noctua fan (will it work? 2. im sorry but i watched ur video just to make shure that i dindt switch up the 2 fans in the motherboard. i've been dealing with a blob of death for the last 2 days but i think im good now

Love the confidence to post a video on a fix when you don't know what you're doing 😂

Mine does the exact same thing when it first turns on. Drives me nuts. Been looking to fix it or replace it!

I have had big problems with getting replacement fans from creality. Getting the wrong fans and the connectors are always broken. in the bag.

I got the fan from Creality on Amazon delivered in two days. What has me upset is the printer is less than 6 month old and the fan is already shot. I have two of these printers and I've already had to replace the BL Touch on both of them. I run them from a Sonic Pad which I had to buy extra usb to serial cables since these printers have no usb onboard. I assume it's because of the Sonic Pad hack they worked up, the printers will not resume a print. They ask if you want to resume then they drive the hotend down through your print trying to home first. I'm about done with Creality at this point.

Hey, bit of a random one, what are the fan screw sizes as I received a new hot end but I threw away the old one with the fan attached 😅 got a new fan but struggling to find the screws.

The fan ends are micro jst 2 pin and I believe pin pitch is 1.0mm

This holds up to the heat in PLA/PLA+??

Had exactly the same issue... got a few drops of 3in1oil, noise gone... given that it is a brushless motor, oil poses no problem... been quiet for a couple of months now...

You need more distance between the fan and the heatsink otherwise you already saw youre getting back pressure from the fan.

mine is new and sounds exactly the same.. it's annoying because its sounds like it's about to die

So, do you not have any problem with printing these parts with PLA? correct? This not melt, all ok?

I had problems with the nozzle melting i printed it using petg, what kind of filament did you use to make it? 🎉

I don’t have a heat gun or soldering knowledge. Any other recommendations to fix it with regular tools and a new fan? (I have KE, not SE btw)

Can anyone tell me if he’s using pla to print that part??? I feel like it would melt lol I know dumb question

Is it a 2010, 2020 or 3010 fan? I found a 4 pack of 24volt 3010 hydraulic bearing fans on Amazon for $6.99- 30x30x10mm 24V Fan DC Brushless Cooling Fan 3010 DC 24V Compatible with 3D Printer Extruder Hotend V6 V5 CPU 2Pin (4 PCS)

Also sounds like it may be wrong voltage

My KE does the same damn thing...trying to figure out how to replace it, because the fans I bought off Amazon seem to have the wrong sized plug.

What's the original fan spec's and size?

Здравствуйте. Скажите пожалуйста, как работает данный апгрейд спустя месяц?

This was painful to watch lol

great video, but i really hope that next time, you will turn your phone around when filming other stuff than tik tok :)

Whats the other mod you have with the white fillament? Where do i out the other fan
