Hi folks, a couple of months bqack i built a new rig for 3d rendering at work. cpu: Core2Quad mobo: AW9D case: http://www.overclockers.co.uk/showproduct.php?prodid=CA-020-AK&groupid=701&catid=7&subcat=507 cooler: Stock retail Now, at idle the cpu temps were 50°C, which at first i felt were a little high, so i replaced the cooler with one recommended to me; http://www.overclockers.co.uk/showproduct.php?prodid=HS-017-AR&groupid=701&catid=57&subcat= But its made maybe 1°C difference, which is not worth bothering about. At load it hits approx. 65°C. On friday the alarm sound because PWM1 went overboard. Questions: 1. Any recommendations on different case or cooler to try to bring the temps down? May be worth trying the cooler 1st as its the cheapest option. Maybe even reseat the cpu with some Arctic Silver, dunno? 2. What are the PWMs? mobo manual went walkabouts, so i don't really know. 3. System temp is low, so maybe a new case wouldn't make much difference. Thanks for any advice.
