I have an old X7DAL-E+ motherboard. Since moving to Hong Kong from Australia the CPU alarm screams at the slightest provocation (HK is a lot hotter generally than Sydney). The manual says its set to alarm at 75 degrees. That means that whenever I am playing a modern 3d game the alarm screams the entire time (even with the A/C on).
Looking in the bios and manual I couldn't see a way to change it from 75 degrees to 90 degrees.
