As far as I know 60-65°C is the Max temp for my chipset Z77. And it never gets that high anyway unless there were extreme circumstances ie: High overclock or a bad power supply as well as really high ambient temperature. I cannot say for sure what the H61 chipset temps should be but considering the Z77 is a performance chipset for overclocking and the H61 might have a lower TDP so The Max temp might be slightly lower than the Z77 depending on the MB. I am sorry I do not have a link or more number regarding this topics but it is generally believed that most 1155 socket chipsets operate at roughly ambient temperature, give a few degrees.....
