Na. Intel built the CPUs, and so they know how hot is safe. Throttle temperature is set at 100c, and emergency shutdown is at 130c.
Be aware that you can't use your intuition with temperatures on modern silicon, and that you can't compare the readings from new and old CPUs. An Athlon XP that read "40c" might well be hotter than your "90c" Core i7, because the temperature sensors are in different places and reading different things. Trust the manufacturer.
