E5450 Undervolting causes serious issues, system remains noisy
E5450 Undervolting causes serious issues, system remains noisy
I have an E5450 in an Asus P5E-VM HDMI. With a stock Intel cooler rated at 90w TDP (actual 80w), I achieve about 50c idle and around 80c under full load, sometimes reaching 85c. I've adjusted the voltages for NB, SB, and PLL to their lowest settings while keeping Prime95 stable, but the Vcore never drops below 1.225v before instability starts. Others report getting as low as 1.15v or closer to 1.1v, so I’m puzzled why mine doesn’t reach 1.2v. I’m not pushing the CPU beyond 3.0ghz and the issue persisted even before adjusting other components. Any advice would be greatly appreciated!
My suggestion is to keep the DEFAULT settings initially, then:
a) swap the CPU cooler, and
b) ensure the FAN PROFILE is optimal (obtain from the Asus website for that motherboard).
The NB and SB models don’t include fans, so adjusting their settings isn’t necessary.

BIOS SETTINGS must be used instead of fan software, but ensure a better cooler is in place to avoid temperatures above 80°C often. A third-party option like SPEEDFAN might work with a new cooler. Update: the recommended fan software is "ASUS Q-FAN 2," though it isn't listed on the site. If you have Vista or newer, the software should function if it's compatible. You might still have the CD or Q-FAN 2 installed.
Photonboy explains the situation clearly. Since there’s no fan software available, you must rely on BIOS settings, though it’s recommended to use a cooler that doesn’t exceed 80°C often. A third-party option like SPEEDFAN might work if you upgrade to a new cooler. An update mentions the fan software should function with ASUS Q-FAN 2, but it isn’t listed online. If you have Vista or newer, the software should be compatible—possibly still on your CD or installed? He notes he’s not overly concerned about temperatures, keeping them under 85°C, and prefers a silent fan profile in BIOS. He mentions difficulty finding a suitable undervolt due to motherboard constraints and that a better cooler would cost too much.
