God, this 760T is so ugly it needs a bag to look at...
Anyway, if you remove the top plastic cover airflow should not be obstructed and I can't see any reason why it would heat up this much. Maybe put some 120/140mm fan on the case fan spot above your memory sticks to blow some air on them? Below 70C should be completely safe for that kit, not that I'm an expert though. I won't believe you run more than 1.5V DRAM Voltage either.
As Pook said, unstable memory can't hurt your RAM. But it will hurt your OS, eventually.
