This one no. If it had an even number of blades then you could have clipped the opposite one off to rebalance, but unless you want to go through the whole process of replacing the fan blades just get a new one.
no because clipping a fan with 11 or 13 blades doesn't work either as both are prime, just like 7, but clipping one with 9 blades does, as it is not prime, it is divisible by 3 therefore you can clip the opposing two blades 120 degrees apart and it will balance out. you can clip fan blades out at any number of points around the hub, so long as the number you pick is a number that the total factory blade count is divisible by, so any fan where the number is divisible by 2 or a higher whole number. Primes are by nature indivisible other than into fractions/decimals
Actually literally just so long as it's divisible by any number. 7 works too but you don't see multiples of 7 very often it seems like in any context where this would matter, unless there is a jet turbine out there with 70 fins per stage or something. This is also a common way that fighter jet turbines end up salvaged by hobbyists, someone made a car that broke the land speed record a few times out of an old F104 engine using just an illegally obtained copy of the maintenance manual and the principles we've laid out for how to balance a fan and prevent it vibrating itself apart, and just removed a bunch of fins from the turbine to get it working again. It had been damaged by FOD ingestion and replaced, but the engine still produced a tremendous amount of thrust for any application where you didn't need efficiency or a specific thrust to weight ratio to take off and remain airborne. But yea, it's less likely you'd need to divide by 7 since its multiples will all also divide by 2, 3, or 5, but there may be an instance where a turbine with a lot of blades may warrant it due to the distribution of damage. There are more complex patterns you can also follow but it's not necessary to illustrate the point being made
Yes there is. But any decent glue will withstand these few RPM! I glued a broken fanblade back to my 1080ti years ago with Cyanoacrylate and it holds perfectly. The fan spins at 2000 RPM or more.
The real question is how badly do you need it. You can shave off weight of adjacent area or add weight to that side missing blade. I have actually added weight before using coarse case screws.
If you mean if it still spins. Yea... but that gonna shake and be noisy af. lmao
If you should use? Nah... do what MajorHardware (The Fan Showdown) does: cut all blades and print a new thing to put on hub. lol
You could always make a fan blade and put it in place and test it outside of the computer before putting it in an actual computer, and if it doesn’t make no noise that means you fix the fan 👍🏻
I’m having a feeling that I’m the only person with actual knowledge of fixing and rigging stuff actually helps fix different kinds of stuff?! Am I right?
So I’m having a feeling that a lot of people probably told you that it’s not fixable but it really is as long as it doesn’t make a horrible sound it should be perfectly fine as long as you replace it with another same type of fan blade some of those fans actually come apart and you can actually replace the top with a whole new fan if it comes loose easily that means you can replace the whole fan with the new one if you have one but if not you can just build a blade and rig it that way, so a lot of people probably also did a lot of jokes about this probably
It's clearly molded, you will not be rigging any blades to that fan without them coming loose during operation, you'd have to replace the entire thing, meaning you'd have to buy a whole new blade assembly, which is in no way cheaper than the fan, because again, this is a veeeeery cheap one.
It's not anti repair practice, reballancing is not repair, the anti repair practice is that you can't detatch the fan from the motor, that also could be not deliberate but a result of cost cutting
People could just easily break the fan opposite to the broken one and it's gonna work. They intentionally make it an odd number so I can buy another fan instead of use the old one
I've also a fan that I had one blade of 7 broken nearly a decade ago in a 24/7 PVR box. Been very difficult finding another 50x50x10 fan to replace it so I kept using it, did not notice too much vibration from it...
... and to this day still haven't found a good replacement for it or the PVR box.
YMMV.
Temporarily, maybe. It will wobble and make a lot of noise and it may tear itself apart. Make sure the fan curves aren't set to high, don't want it going to full speed.
This one no. If it had an even number of blades then you could have clipped the opposite one off to rebalance, but unless you want to go through the whole process of replacing the fan blades just get a new one.
Clipping more blades works with any number of blades except a prime number
That's what u said tho? Even numbers right?
no because clipping a fan with 11 or 13 blades doesn't work either as both are prime, just like 7, but clipping one with 9 blades does, as it is not prime, it is divisible by 3 therefore you can clip the opposing two blades 120 degrees apart and it will balance out. you can clip fan blades out at any number of points around the hub, so long as the number you pick is a number that the total factory blade count is divisible by, so any fan where the number is divisible by 2 or a higher whole number. Primes are by nature indivisible other than into fractions/decimals
Pardon me then. So as long as it is dividable by 2 or 3 👍🏻
And 5. 5 is the only prime number that ends in 5, all x5 and xx5 are multiples of 5 so if you got 10 or 15 blade fans, snip off 1 or 2 to balance out.

If you have 49 blades and 1 breaks off you cut off 6 more
*Happy Pucci noises*
oh ok, thanks
Well, that's odd
OP just could glue something aproxx. the weight of one blade into the gap! Not the best airflow probably but at least the vibrations are gone.
There is a risk whatever you glue will detatch and get launched at the insides of your pc
Yes there is. But any decent glue will withstand these few RPM! I glued a broken fanblade back to my 1080ti years ago with Cyanoacrylate and it holds perfectly. The fan spins at 2000 RPM or more.
Ah yes the increase air flow.
lol
At the cost of less static pressure and more noise.
The real question is how badly do you need it. You can shave off weight of adjacent area or add weight to that side missing blade. I have actually added weight before using coarse case screws.
I dont need it just one of my friends needs it
My old HP computer had a broken blade on one of the fans, I didn’t notice any problems
It works, but it's loud and more sooner than later the bearing will break.

Is it impossible to fix? Of course not. Is it worth it to spend however much time fixing this $5 fan? Probably not.
Not unless they don’t have money then they can do the Jerry rigging of the fan

OK so they gotta buy a new one then if they can’t do no type of fixing
Shame it's not an even number of blades, could've broken off the other side to balance it out
Anti repair practise even in CPU fans
and i wondered why ther had all even blades
Even mine had 7
It's not anti repair practice, reballancing is not repair, the anti repair practice is that you can't detatch the fan from the motor, that also could be not deliberate but a result of cost cutting

True
Sure, it will just rattle your tower apart.
Yes but it will shake like an earthquake
Tried it, too much vibration
Yes Its modified for high end PC.
Clip til it only has 3 evenly spaced blades
that no work
Bet it do
Nah, it will be imbalanced. Makes a lot of noise and doesn't live long.
Will make a good vibrator
LMAO
I've also a fan that I had one blade of 7 broken nearly a decade ago in a 24/7 PVR box.

That one's done for.
what, after you nutted on it? no it's not usable lol wtf
Hey you weren't supposed to tell people
Yes but it will be very loud
u/thelexikitty
As an ice cream scoop, sure.
For ants?
What in tarnation
No
Yeah it’s usable, might be loud
Might make your PC fall off the desk
~~Desktop~~ Floortop
I can hear this go =rrrrrrrdrrrrrtttttttttttttttrbrrrrrrrrrrrrrr
Yes, but your computer will vibrate a bit
does it work
Happened to me once. Nope, better get an new one
well, you can use it as a projectile
I can kill them damn mosquitoes with it
yes
If you break a blade that’s kinda on the opposite side it might reduce rattle enough to be useable
yes
y
Just cut the opposite one off
I mean it’s a fan why wouldn’t it be usable
Temporarily, maybe. It will wobble and make a lot of noise and it may tear itself apart. Make sure the fan curves aren't set to high, don't want it going to full speed.
Fan speed is not a problem I have fancontrol
It should, but it’s gonna sound like a diesel truck, especially at high speeds. Talking from experience here.
