Yes I do had the same problem with my core 2 duo E4500. I installed a slightly larger heat sink that somewhat solved the problem. But ultimately I have go in for an upgrade of mobo and processor because of Windows 8 lol. Gigabyte mobo with AMD FX 6300 6 core processor. Because of too many reinstall and automatic repair I have exceeded maximum limit of automatic authentication of windows 8 by windows server. So hereafter I have to phone up Microsoft help line to activate my windows 8 each time
on reinstallation or repair. Please down load and install speed fan or coretemp software and monitor the CPU temperature.
