Intel's Ivy Bridge chips run hotter than predecessors when overclocked
You may want to hold on to your wallet if you intend to grab hold of a new Ivy Bridge processor and overclock it. Overclocking in this context refers to forcibly running a microprocessor at a faster speed than intended by the manufacturer in order to gain a higher level of performance. The problem is that Intel's new Ivy Bridge processors get dangerously hot when pushed to the limit, to the tune of 68°F (20°C) hotter than a comparable Sandy Bridge processor.
According to PCWorld, an Intel (NASDAQ: INTC) i7-3770K processor operated at 4.9GHz by increasing the CPU voltage will see the processor temperature rise to about 212°F (100°C), the temperature of boiling water. Several theories were offered, including the greater number of transistors, lower default operating voltage chip or the comparatively less mature 22nm manufacturing process used to make the Ivy Bridge processor.
As reported on The Inquirer, Intel has maintained that the Ivy Bridge "meets quality and reliability expectations for parts operating under specified conditions." The company does however confirm that "users may observe higher operating temperatures when overclocking."
In a nutshell, overclockers may want to avoid Ivy Bridge for now.
