ditto Correon... I also have probe, I've set it right beside my cpu wedged under the heat sink(contact with both). My pc supports core temps; when comparing prob at idle(29c vs 36c)/load(39c vs 45c) about the 5-7 degrees lower than program, case temp 25c. Beware as it fluctuates depending on temp in side case. Cooler in winter and hotter in summer.
