I have a X5650 Xeon running at 45 degrees Celsius idle. I want to reduce the temperature. I changed thermal paste but I want to also configure it so its cooler. I've heard HT can increase temperatures by 8-10 degrees on modern CPUs but I am willing to try disabling it on mine to see how much cooler it will go. About 2 years ago I went into my Dell Precision T3500 bios and turned on HT. Since the CPU is a 6 core one I doubt I will benefit from HT based on my work load. My question is - if I turn it off from the BIOS will I get any errors or problems when I boot into Windows? I am running Windows 7 Professional 64 bit. Thanks in advance.
