As I joined the new PC party a month or two ago, I am rocking 2nd Gen i5 – Sandy Bridge CPU. The 3rd Gen Ivy Bridge chips came out recently and have been tested to show that the reason for higher temps than the last gen, is because shitty thermal compound in use under the heat spreader.
Bad start to a new GPU line, where a few cents for better compound could have really made the release more interesting. For now, if you get an Ivy fab chip, know what you are in for.
