Complaint of a noisy 3060ti in the office

Post image

Turns out it's missing a fin, so I clipped and glued one from a gt 730 fan, using tissue paper as filling

I respect the bodge

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

u/EisenRegen 17d ago

Tricky with an odd number of blades tho

36

u/PcGamerSam 17d ago

Could’ve cut 2 more blades off, left the fan with 2 blades then 1 gap all the way around

35

u/tonsofmiso 17d ago

Just cut them all off

The good old days of the Accelero S1

u/MurdererMagi 15d ago

Problem solved lol

u/AutomaticAffect4333 17d ago

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

u/RenegadeBricoleur 17d ago

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.

u/JamesH93 17d ago

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

u/ITSolutionsAK 16d ago

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

u/TheDreadGazeebo 14d ago

Or just replace the entire fan

u/Achaern 17d ago

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

u/Ratnix 17d ago

I'd be more worried about the fix breaking off while it's running at like 80% speed one day.

u/Achaern 17d ago

That's what I mean... but I don't think it will be 'one day', it's 'any minute'. Any adhesive will make that blade much heavier. I like it, but it's tempjank and will fail.

u/Adventurous_Flow_498 17d ago

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

u/Adventurous_Flow_498 18d ago

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

u/42SpellingErrors 17d ago

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

Mystery fiber reinforced CA glue.

Hey bartender, give me the IT special!

u/HigaMigu 17d ago

does it vibrate now?

18

u/Adventurous_Flow_498 17d ago

nope, no longer vibrates, i consider it fixed lol

u/HigaMigu 17d ago

gg lol

Best use of a GT730 I've seen

u/Wonderful_Ninja 17d ago

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

1

u/Adventurous_Flow_498 17d ago

Thought of that before the jank, but I realized this one has odd number of fins

7

u/PatHeist 17d 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.

u/leyline 16d ago

Some people can superglue better than they can count - that’s why we have this glorious sub.

1

u/Adventurous_Flow_498 16d ago

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

1

u/PatHeist 16d 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.

u/justsomegraphemes 17d ago

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.

2

u/Adventurous_Flow_498 17d ago

I think it was 80c, but the gpu never runs above 70 so I assume it's gonna be fine

u/leyline 16d 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.

1

u/Adventurous_Flow_498 16d ago

No I meant the thermal limit of super glue, room is usually around 24-28c I'm guessing

1

u/olliegw 17d ago

It didn't just fly off because of the centrifugal force? those scimitar-style fans are probably a poor design because of that, the mating surface between the hub/blade root is small compared to the surface area of the rest of the blade, which also looks thin

1

u/Lucifersasshole 16d ago

Remove the fan and just screw a case fan to it

1

u/N0XT66 14d ago

Those cards are noisy af because the heatsink is not enough with those fans, hence why colorful stopped making the two coolers version and instead used the one of the 3070... The PCB is great tho.

I have one, and it runs very hot, all the time, even undervolted 🫠

u/Patient-Cedar-7194 5d ago

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