Another round of would you eat this?

Still cold to the touch?

I think you'll be fine.  As long as it wasn't too hot.  If it's still cold to touch, I'd say you're ok.

I agree that if it's still cold I would keep it.

If you keep the refrigerator closed, food is good for 12 hours

Wouldn't enter my head to throw anything out.

Definitely I would eat all of those. I've kept yogurt out of the fridge for that long many times if I take it in my lunch... Often the teacher I'm subbing for doesn't have a fridge in his/her room and I'm just too lazy to go track one down. My yogurt -- usually homemade, so it's not even in a factory sealed container -- is in my lunch box from about 7:15 when I pack it until lunch which could be as late as 12:30. No problems. Same with the cream cheese. 

As for the heavy cream, it's most likely ultra-pasteurized. And anyway, it's easy to tell if it's spoiled because you can just sniff it. 

I can sympathize with not wanting to throw stuff out. Last year, we lost power twice within about two weeks for extended amounts of time- so, just enough time to have replaced almost everything we lost the first time. It killed me, but I tossed almost everything again. And then we had a three or four day brownout. Anyway, I have had food poisoning and it isn't something I want to repeat, so I err on the side of caution always.

I'm super neurotic about this stuff and even I would still eat it.

I think it’s fine.
