i have this Dell computer a Studio XPS-9000 with 9 GB of RAM, Core i7 processor 985, 3.33 ghz. At first, when running Cubase with several VSTi’s and plugins it was super quiet. Then the computer fans started to rev up after about 3 months when the Play button was pressed. Called Dell and they sent someone out to change the fans. Which were a little dirty but not real bad. After this, Cubase ran smooth again. Now it revs up with 3 instances of Halion Sonic, 18 mono tracks 16 bit, and 16 midi tracks. i open the task manager and the cores are running pretty even (all cores are unparked) but the computer starts to rev up. i thought that this was a pretty powerful computer and would handle my Cubase app. i also record my vocals right in the room where the computer is so, the extra noise is not a good thing. Is this because of the Hyper-threading deal (first generation i7)? Should i disable any Cores in the BIOS? i hope this is understandable. Kind of a noob . Oh i forgot, i got the computer Jan. 2010. Thanks for all help.
