Wine Crumudgeon advice?

[sharky]

Sorry if I spelled it wrong. With keeping a group of Cabernets I have two options A) room temp on the eastern coast of the U.S. where temps indoors can reach as high as 89F or in a refrigerator where the temp is normally around 70F? I have heard that an ideal temp of ^*f is preferrred but on my budget it would be a luxury to buy a fridge just for my wines. I normally try to keep between 8-12 bottles of the Cabs on hand for personal consumption or visitors, any advice is well apreciated.
