Symptoms of overheating without an overheating card?

I'm among the group of people who's too poor to afford water cooling at the moment, but concerned enough about temperatures to keep GPUz running on my second monitor while I game.

I have an R9-290, which as you've probably heard is designed with a target temperature of 95c. I have the Catalyst software set to ramp the fan up starting at 75c, just because.

Recently while gaming, (specifically Half-Life: Source), I encountered some rather serious graphical corruption that I've often seen attributed to an overheating GPU, but at the time it occurred my GPU was running around 65-70c. I happened to be recording with Fraps at the time, so I've included a clip showing what happened.

Any idea what is going on here?
