Aging oaked porter

I brewed a bigger (1.088) porter on new years day and oaked about 6 weeks. The idea is to let this beer rest to enjoy around Christmas. I can age at 60-65f or about 40 in the kegerator. Which would you do? I know ideal is around 50 but that’s not an option. I’m definitely leaning towards 40, but wanted opinions.

My vote between the 2 options is 40*

I agree, 40 till Xmas would be the better way to age. You already. Aged warmer for 6 weeks on the oak. Long-term aging warm has no benefit that I know of, and could impart some staling.
