[Request] How long does it take a can to reach equilibrium temp in a fridge?

Curious how long it would take for a 12 oz aluminum can of liquid to reach an equilibrium temperature inside a normal, average fridge. Assuming a normal fridge, and obviously how much the fridge is opened during the time, but I’m only interested in the perfect scenario of it staying closed for however long it takes. I suppose if you want to go above and beyond then it would be cool to know how a single open of the fridge would affect that! I’d also be interested to know how much the math changes (assuming it does at all) depending on what the drink is, such as the difference between a soda, beer, or like a sparkling water.

(The can is starting at room temperature)

using newtonss law of cooling with a typical fridge convection rate the can hits within a degree of 4cc in about 35 minutes from room temp if the door stays shut the whole time

Practical observation doesn’t seem that they cool that quickly.
