Use the new speedfan and offset your core temps by 15C it is alot nicer to use than TAT and speedfan can sit in your taskbar giving you warnings if your CPU gets hot.
Also is it normal for E4300's to be v hot!? I am running @3.0GHz 1.3375V (in BIOS about 1.29V real) with F@H running and the stock heatsink seeing 60C loaded temps!
I am getting water sometime next month but would love to know what other people are getting with the stock cooler under load.
