Intel recently released Ivy Bridge named 22nm processors and all the launch day reviews pointed out that they run considerably hotter than their predecessor, Sandy Bridge. Along with 22nm manufacturing node, Intel also introduced tri-gate transistors with Ivy Bridge.
There were some reports that high temperatures of Ivy Bridge might be due to the fact that Intel is using TIM inside IHS instead of flux-less solder but testing by a PC EVA forums members showed that its not due to the TIM.
Surprisingly, Intel has admitted that their latest Ivy Bridge platform runs hotter and its because of the increased thermal density which is the result of 22nm manufacturing node. Intel said, “users may observe higher operating temperatures when overclocking”. They further added, “This is as designed and meets quality and reliability expectations for parts operating under specified conditions.”
This means that even though Ivy Bridge runs hotter but one shouldn’t be worried about it because its designed this way and it meets all the quality and reliability expectations.
