Thread: Fan spins later altering from high-Quad Core

Hi, i substituted Intel Core 2 Double E6850 with INTEL Core 2 Quad Q9550 2.83GHz Processor. The board is Intel DP35DPM The central processing unit is cooled through a Zalman CNPS9700 NT. According to Speedfan the central processing unit is at 20 degrees. The fan functions but at complete load? Any recommendations and advices are appreciated.

Forget the BIOS inform. Create it excellent not. 20 ° is ever exported fault, because 20 ° with an air cooling? In any case, 20 ° look to me so little. Far also little. Should have 30 to 45°.

Do not depend exclusively on BIOS for exact voltage measurements, but rather utilize a DVM to measure every voltage rail at the 20+4 pin CPU board connector, and at the 4 pin CPU motherboard link. Regardless, it looks that your power supply unit has failed.

The 4-pin links w / PWM were planned to furnish automatic fan RPM control with a CPU board that supports the so PWM characteristic. Few motherboards are skilled with 4-pin links but lack the PWM characteristic. Upon intallation of a 4-pin PWM fan to such a case, the fan will function on maximum RPM, making the excess noise. For CPU boards that support PWM, PWM check the view in your BIOS setup.
