It's a new build, but it's always had noisy fans. From start to end, they will not stop running. The case is a cooler master which I believe comes with a fan that is not controlled by BIOS (according to technician), so that may be the source of the problem..but my lack of knowledge on the matter prevents me from making a reasonable assessment. Here are readings from CoreTemp: Model: Intel Core i7 870 (Lynnfield) Platform: LAG 1156 (Socket H) Frequency: 1658.23MHz (132.66 x 12.5) Tj. Max: 99 C Core #0: low= 34 C; high= 42 C; Load= 0% Core #1: low 31 C; high 42 C; load= 0% Core #3: 35 C; 42 C; 0% Any input will be appreciated.
