I'd have to agree with you in regards to pushing the GPU to hard. I noticed when I first ran the game with reflections on, my fans automatically started to become more audible than usual. Then, when I would downsample, the fans again worked harder. In the end just cranking my fan speed up to 70% from 30% helped reduce graphical abnormalities.
Right, that's definitely your GPU overheating then. There are two things you can do to make your life a heck of a lot easier, and play without worrying:
1) Manage your rig's airflow. How many case fans do you have? When I had overheating issues with my SLI GPUs I slapped in two more (high quality, and low noise) case fans. 1 side intake, blowing cool air directly onto my GPUs, and one top exhaust, sucking hot air out of the case. That helped keep my temps down
drastically. You don't need high speed fans, you just need to make sure the air is flowing over your GPUs, and then right out of the case. It works wonders, and allows you to push your cards harder
2) Download MSI Afterburner. Set up a custom fan curve. This is even more useful than installing extra case fans, because the program manages GPU fan speeds automagically. So when your GPUs are idle, the fans will run at around 20-30% speed. When you're gaming they will set themselves accordingly, bumping up to 50-60% most of the time, and jumping up to 70%+ as and when they need to. You don't need to worry about setting high fan speeds yourself, and the cards will only get noisy when they need to be noisy.

Well worth taking the time if you're into modding games like Skyrim to look like next-gen experiences.
