A770 Coil Whine
A770 Coil Whine
Hello everyone, I bought an Intel Arc A770 with 16GB limited edition and after a quick test I’m happy with its speed and quiet operation, aside from the coil whine. I’m not sure if this is typical. The issue I faced was unusual—initially very loud, but after about 10 to 15 minutes of stress testing, the noise decreased below what I could notice (around 37dB at 1800RPM fans). Do you have any advice on how to test or resolve this?
In general, you can't really do anything about coilwhile. It's like silicon lottery.
In theory, swapping parts might feel like getting a completely free upgrade. It's essentially a risk. Hopefully, you'll end up with a GPU you actually enjoy using.
Fixing coil whine isn't always possible; using thermally conductive epoxy in chokes might help, though it's not a sure solution since capacitors can also produce this noise. Whine has existed since power supplies evolved—replacing transformer buzz with a higher-pitched sound over time. As power demands grow and switching methods change, it’s becoming more common to hear it. I’ve noticed whine in my light bulbs, a surround receiver, even an old Atom motherboard. It’s somewhat bothersome, but you adapt, especially when playing games quietly. Game audio should usually mask it, unless you’re in a completely silent environment where it becomes overwhelming.
You're right about it being a lottery with a high cost. It might be better to skip it, even though I'm inclined toward A770. Also, my 1660 isn't too low, so I could hold off until the next round.
It's not something you'd usually try, as manufacturers typically handle it themselves and it tends to be costly. Sometimes the issue isn't with the device itself—on my setup the problem was the SoC, which seems to happen with chips too. Getting a new card without any issues is possible, though it might develop later. My surround receiver didn't complain when it first came in, but my 4090 tends to whine over time, even if it doesn't affect gameplay.
It seems the system warmed up over time, slightly slowing clocks and moving it out of the whine range. A possible fix was to cap it sooner. Alternatively, another factor might have affected it thermally. Still, if replacements are happening, please share your experience with the new unit.
It seems there are significant and unpredictable changes in current flow from low to high loads. Over time, the load stabilizes, making the coil whine unnoticeable. These interpretations might occur simultaneously.
