I have no idea where it came from but a siren nose just began sounding. I quickly checked my temps. My GPU was at 54 C my CPU which I have a constant epox probe on it was running at 35 C which for idel is slightly high but not EXTERME. I quickly shut off of the PC and went into BIOS. I NOTICED NOTHING. I checked all my readings and I noticed a few slighther high temps but not by any means enough to worry about. I wasn't do anything demanding at the time... Any ideas.. I noticed NOTHING ouit of the norma nd I was simply on IRC.
