First off, I have read the sticky But then I also read the CPU Temp list and this still seems suspiciously hot... I used PC Wizard to make these measurements when the PC was idling: Hardware Monitoring : ITE IT8718F Voltage CPU : 1.12 V +3.3V Voltage : 3.38 V +5V Voltage : 5.15 V +12V Voltage : 1.29 V VTT : 1.73 V VBAT : 3.14 V Processor Fan : 1038 rpm Chassis Fan : 10 rpm Power/Aux Fan : 10 rpm FAN3 : 1132 rpm Processor Temperature : 39 °C Mainboard Temperature : 29 °C : Processor : Thermal Diode Intel Core 2 Duo (Core 1) : 53 °C Intel Core 2 Duo (Core 2) : 48 °C : NVIDIA GeForce GTX 260 : nVidia Driver GPU Temperature : 52 °C GPU Ambient : 40 °C GPU Fan : 40% : The strange thing is that the case shouldn't be anywhere near that temp; it's got a 25cm intake fan on the side, another intake at the bottom front and a 12cm outtake fan on the back. I put my hand over the outtake fan and even under a heavy load of gaming it's not more than lukewarm. But the core temp under load rockets to high 60s, not healthy. Any ideas what could be causing it? I can't do much more to increase the airflow; all the fan points are covered and the 25cm behemoth is bringing in enough air from outside. EDIT: The two 10rpm fans aren't connected to the motherboard so I would guess that's why they don't have accurate readings; they're clearly going more than 10rpm by eye!
