I recently bought an X5670 Xeon CPU and slapped a stock cooler on it. I got the Intel DX58OG mobo so that i can maybe overclock it in the future, but as of right now, I cant even run it at stock. I used the Intel Extreme Tuning Utility and the stress test in it showed that my cpu thermal throttled when it reached 90C(when it was 60C idle). So I put some new thermal paste and found that it was now at 45C idle, but when I ran the stress test again it reached around 65C but thermal throttled??!. I went into my bios and set the voltage to like 1.5 and lowered my multiplier to even less than the stock and it is still thermal throttling at ~65-70C whereas before it would reach 90C without throttling to 1.8ghz. Someone help I am so confused, could it possibly be the cooler or some setting in BIOS, any help would be appreciated, thanks.
