If the problem disappears (for a while) when the freezer reaches 32F, then I know what the problem is.

The GE Profile refrigerators (and likely other models as well) often don't defrost properly, especially in humid climates. So they can develop ice buildup internally, especially if the air vents at the back of the freezer are blocked by frozen food. Once that happens, that ice can interfere with the cold air circulation booster fan that runs when the freezer temperature is too warm. Then you get a LOUD buzzing noise from the fan blades, as they bang into the ice.

The immediate "solution" is to be sure nothing blocks the air vents, and then to melt the ice that interferes with the fan. You can turn the fridge off for a while (with the food removed so it doesn't spoil), and/or get a hair dryer and heat the inside back of the freezer, until the ice melts and falls away from the fan. (Just be careful not to block the nozzle of the hair dryer, or it may burn out from overheating!)

But the ultimate solution is to buy another refrigerator, one that is NOT a GE! And that makes me sad, because GE used to make GREAT refrigerators. My last GE refrigerator is nearly 20 years old, and still works well, and it does so QUIETLY.

Eeeh, this will prevent you to spend more than you have. Carefully unplug your fridge, remove it from the wall for about 1 foot wait 15 mins and plug back and let it stay there for ever.
