Intel recently launched their latest 22nm Ivy Bridge processors and against everyone’s expectations it runs pretty hot which also limits the overclocking. Guys over at Overclockers.com took the matter in their hand and started investigating the reason of high temperatures. They have found out a potential factor which could be causing high temperatures. Upon carefully removing the IHS (Integrated Heatsink), they found out that Intel is using TIM to transfer heat between the IHS and the die. In case of Sandy Bride, Intel used fluxless solder and according to Overclockers.com fluxless solder transfers heat much efficiently as compared to TIM and this is probably the reason behind high temperatures. You can check our review of Ivy Bridge based Core i7-3770K to see how hot it runs.
There is no response from Intel on this issue yet but we’ll keep you guys posted.
