CPU / MOBO hissing under load

[JimAroo]

Hi,

After wrestling with my E6750 to get past the 3.2/3.3 Ghz FSB wall, i managed to get it to boot into windows at 3.4Ghz. I'm conserned about stressing it longer than 10 minutes as everytime i stress my CPU i get a Hissing sound.. this instantly stops when i stop stressing my hardware.

My temps are all fine:

MB: 43°C
CPU: 36°C
Core0: 49°C
Core1: 49°C

Anyone know if this Hissing sound is anything to be wary about?

Sounds like a capacitor is hissing under load, which is nothing to worry about.

Phew, I'm glad, just a little paranoid about Mobos, as the last 2 i had randomly booted up to find they had No BIOS (Must have been eaten by the bios monster or something).

Thanks.
