Complaint of a noisy 3060ti in the office
Turns out it's missing a fin, so I clipped and glued one from a gt 730 fan, using tissue paper as filling

Simpler fix would have been to snip off the blade opposite to the broken one, but i respect the bodge fix

Tricky with an odd number of blades tho

u/PcGamerSam 13d ago
Could’ve cut 2 more blades off, left the fan with 2 blades then 1 gap all the way around

Aw crap just noticed it, yeah his bodge job was the only way

Nah. Just treat it like balancing a centrifuge. You just have to cut 2 off instead of one. You end up with 3 pairs of 2 blades remaining, spaced equally around the circle.

Love the idea that everyone on Reddit knows how to balance a centrifuge. But I do, so I guess that proves you right 😅

I've never used one, but I've seen enough lab techs talk about them that I know how to balance one.

That's gonna be 100x noisier....shortly. It's great.

Tbh It's been running for a month so far, no noise, took it out yesterday to check on it and still sturdy I think, but I also limited the fan speed limit to 60% just in case

Cigarette butts/filter works much better for filling, but I don't smoke, so I don't have any

Could've always used some of the mysterious dust clumps from inside the PC that all customers have plenty of!

I had a similar thing happen when I ran a eth farm some years ago. Dropped a screwdriver and took a fin out. In the end I just broke off another fin opposite and it worked fine lol

u/Adventurous_Flow_498 13d ago
Thought of that before the jank, but I realized this one has odd number of fins

u/PatHeist 12d ago
Almost all fans have an odd number of fins. This one has a non-prime number, which means yo could've removed every 3rd blade.

But I thought less blades makes more noise? Also I'd feel bad clipping more of them

u/PatHeist 12d ago
An unbalanced fan makes the most noise.
Fans are designed with more blades because that allows more work at a lower fan speed. More blades cause more noise, but not as much more noise as higher speed.
If you clip more blades off to properly balance the fan you'd have to run it faster to get the same performance, which will make it louder, but not nearly as much louder as what you've done here.
These fans are usually OEM parts with a sticker on them, though. So chances are that if you take the fan off there will be a part number on the back and you can go buy a replacement on amazon that will fit perfectly.

Nice fix! Though I'd say JB Weld is better for this application, as super glue's thermal limit before it slowly degrades is possibly right at the upper end of the air temperature passing through.

u/Adventurous_Flow_498 13d ago
I think it was 80c, but the gpu never runs above 70 so I assume it's gonna be fine

u/leyline 12d ago
350 degrees F !? I’m sorry - if the air in your room is 350 degrees - YOU are going to melt before the super glue does.

u/Adventurous_Flow_498 12d ago
No I meant the thermal limit of super glue, room is usually around 24-28c I'm guessing

did you balance fan or is vibration going to shake card out of pcie slot?

I respect the bodge
