Hello all, name's Kane. My father recently got himself a new computer and gave me his old one, and as a gamer I've been looking to get the most bang for my buck out of this system. Me and him took it down to parts and cleaned everything, along with an alcohol wipe and brand new application of some Arctic Silver 5 thermal paste (straight line applied). It's only been a day so I'm planning on letting it cure for another couple of days before I attempt overclocking (I had heard that was necessary, but I'm not sure), but first I need advice from the good people of this fine forum! My CPU is an Intel E8500 (Wolfdale) sitting at 3.16ghz. It has a new application of Arctic Silver 5 thermal paste, and a ThermalTake CL-P0497 cooler on it. Under Idle I've noticed a discrepancy in temperatures, and I've tried multiple different programs and they all report the same. Under complete idle my cpu's have a temperature range of about 5C. The first one stays around 34-35C, but I cannot get the 2nd core to drop below 39-40c. I read about how it could be stuck, so decided to run the Real Temp sensor test and had some odd results. I'm not quite sure how to interpret them, so I'm hoping you all can help me. My questions are two-fold. One: Is my computer safe to be overclocked with the load and idle temperatures you see in the image? I plan to push it around 3.8 ghz, nothing too high or fancy. Just want a little boost. Two: What is up with my CPU and why is there a discrepancy in the temps under idle, and to a lesser degree, load? Is my CPU going to be fine to handle the load of OC'ing? And are there any tips or things I could do to help my system or fix anything that might be wrong? Sorry if I seem a worry-wart, I just want my computer to be in prime-shape for overclocking, never done it before and I don't want to bust my system. Anyway, thanks for reading and I hope to hear back with some good answers! EDIT: Forgot to mention, room temperature at the hottest part of the day is about 30c, dropping to around 26c at night. Don't know if that affects anything but felt I should list it.
