Recently I upgraded my computer from an intel Core 2Duo, to a Phenom II X4.
I've ran into severe heating issues. I've never had heating issues in the past with my case. I've tried the stock heat sink, and a new heat sink. If I run prime95, within a couple minutes the temperate is up to 65+. I've had it spike to 70 degrees while Idle. The cpu and the heatsink are not hot to the touch, which is what I would expect with this issue. I kind of suspect its a bad heat sensor. The other temperatures in my computer don't go over 40 or 50 even under load, except for my gpu but its known for running hot.
Speed Fan is showing a constant 50-60 degree temperate underload.
CPUID HW Monitor has recorded it with 50-70 degrees with a median of 64.
I am thinking of sending the CPU back in to get exchanged, but would like some input/feedback.
Oh and just to test the airflow of the case, I removed the side and put a fan on high right next to it, it lowered the ambient tower case to 28 degrees, while the processor stayed at 55+ with just having World of Warcraft open.
and just to make sure I am doing it right because I am driving myself nuts trying to figure this out.
I am taking a bead of the thermal paste onto the heatsink, spreading it thin with a credit card till it cover the whole heatsink, but so it smooth also. Putting it on the cpu, twisting just a bit to spread it and then clamping it down.
I just reput in the second heatsink, and found it fit with a slightly tighter bracket stting, still getting 60 degree readings on it right away without much load.
