Undervolting the 3080 can help a lot with thermals and sacrifices minimal performance up to a point. I undervolted my 3090 and it improved thermals by like 5-10c depending on the workload which lowered the fan noise and as a bonus lowered the coil whine. I don't have numbers on the power draw though but it should be a significant difference

To be honest, a 1500 dollar grapics card that has audible coil whine is appalling. Why didn't you RMA it?

  I did RMA it once. The new one had the same issue and it took a month to get to me. So I didn't want to go through that again. The coil whine also only happens on certain games. Most of the time there isn't any

    Make sure you take the case cover off and get a paper towel roll and put it up to your ear. See if the sound actually is the GPU or the PSU. I've had this a time or two, swore it was the GPU and it wasn't. RMA'd the PSU and my "GPU coil whine" was gone.

I ran a beefy (3 power inputs) 3080 undervolted and you don’t really lose more than a few percentage points of performance and it ran great on my 650W with a 3700X. I much prefer a little performance hit to loud fans

Undervolting can even improve performance: my stock 5700 xt runs at 1.2V and reaches 110°C hotspot. It then drops the frequency a few hundred MHz to stay below the temperature threshold. By running it at 1.1V it reaches 90°C hotspot, below the 110°C threshold so it runs at maximum frequency constantly. Many GPUs (and CPUs) have their stock voltage quite high because it improves yield for the manufacturer. Unless a GPU is really bottom of the barrel regarding silicon lottery, it can usually be undervolted without issues. This is however less true for flagship models which are already pushing the silicon as far as it can.

  > Many GPUs (and CPUs) have their stock voltage quite high because it improves yield for the manufacturer. The higher voltages don't improve yields since manufacturers usually bin parts by testing them at higher voltages, decreasing them until the part passes the whole test suite for a grade. The primary pressure on stock voltage is headline numbers like core count and clock speed that consumers have been trained to compare by decades of marketing. This is especially obvious with laptops and desktops geared at gamers, which will often come with an even higher voltage than the recommended stock Intel profile at a detriment to performance and efficiency - doing it just to be able to list higher numbers on the specs page at the expense of the usability of the machine.
