Chirping fan noise on MSI RTX 4070 Ti Super Expert
Hey all,
I’ve been hearing a strange chirping noise from my MSI RTX 4070 Ti Super Expert. It’s definitely coming from the GPU fans, but only at certain RPM ranges. For example:

A few times around 40–45% fan speed.

Over the last 3 months I’ve also noticed it occasionally at 55% and 78% fan speed.

The exact RPM zones seem to shift depending on the driver version, which makes me think it’s PWM/fan curve related.

I don’t hear it during stress tests — only when the fans hover around those specific speeds.

All fans seem to spin perfectly fine (no grinding or wobbling), temps are normal, and the noise disappears if the fans move past those “zones.” From what I understand, it might be some kind of resonance issue with dual-fan cards, not coil whine.

Here is an example: https://voca.ro/1g9nu1uBJ1Un

Has anyone else with the same card (or other MSI dual-fan GPUs) experienced this? Did you fix it with a custom fan curve, or is it just one of those harmless-but-annoying quirks?

I can’t hear anything unusual on my end, just the usual fan hum no chirping or coil whine. From your description it sounds more like a resonance issue with the fan curve rather than typical coil whine. sometimes dual-fan GPUs exhibit this at certain RPM's. You could try adjusting the fan curve yourself it’s usually straightforward and often resolves these minor quirks.

Actually, yesterday I heard it at any RPM speed, but today less - it seems random. Actually, this sound is more like a low-pitched squeaking from the fans. And it is so weird because I have never seen both of GPU fans fail in less than a year of use.

most fans you can take apart and add a drop of oil to its bearing
then carefully clean it an put the sticker back on

Look for skateboard bearing oil or sewing machine oil. Chainsaw and similar machines also have decent oil for that. Or bike chain oil, but make sure it's "thin" bike chain oil. You don't want anything too thick. And just a tiny amount, don't over do it. Most fans have a sticker or cover for easy access to the bearings or the shaft. Both ways should work in most fan designs.
Use many types of oil before and most work anyway.
If the fan is a "standard" size, it's probably cheaper to replace the fan if you actually need to buy a bottle of oil but if you have access to some, it's "free". If you get a new fan make sure the fan and the connectors are the same.
My current CPU fan and one of the case fans are about 5yo and no problemas ever. I guess luck also plays a part. You live in a very high humidity or dusty zone? Could also be that. Could also be that the fan is damaged/misalign, either from factory or it got drop by you, the couriers or the warehouse people. Sometimes the damage is so minute that it only has symptoms later on.

I also have a case fan that's been spinning since 2016 with no problems. I live in a region with low dust, and the humidity here is actually pretty low (in my flat, at least). I clean my PC at least once every couple of months. I spent some time adjusting the fan curve, and now the shift from 40% to 50% is less noticeable and became quieter.
