CVT whine

Most days when traveling the 38 miles it takes to get home, if I drive more than 65mph on the interstate, the CVT gets really whiny by the time I'm in the last mile or two. Does anyone think a larger transmission cooler or adding a transmission cooler might be a good idea? I'm just thinking that if it is struggling that much to make the car go...even under normal highway speeds...that cooling things down might help out? I'm not getting any ecm/transmission codes, so I know its not overheating. Perhaps the "gear" whine is normal. Thoughts?

I'd have to do some research like Mike says to see what causes this. I've not experienced it myself. Does it feel like it's slipping or just get noisy and work as normal?
