Hi. I have one question : I just bought amd athlon 64 x2 5000+ without cooler because in my PC there is amd sempron 3400+ with stock cooler. When I inserted new athlon, the speed of fan was at maximum and PC would restart after several minutes. After that I used hwinfo, looked at temperature of athlon and it was starting from 60°C till ~95°C and shutdown. Is that just a cooling problem or something else? Normal temperature at sempron is around 44°C. Motherboard is GIGABYTE M61PM-S2, CPU is sempron clocked at 2.41GHz and temperature is around 48°C.
