Was playing Battlefield 4 tonight, when my system turned off, and rebooting with a POST message saying: "CPU Over Temperature Error" First time I have ever seen that, and usually my CPU never gets higher then 50. I took my headphones off and noticed that my system seems a bit quieter, no pump noise really. Turned off the system. Let it sit for a bit, turn it back on, and noticed my GPU temp got to 50c on boot, it doesn't even hit 40c in games. Stuff seems to be fine now though at idle, GPU temp is 26c (still a bit high) CPU at about 23c (which is normal). I have noticed that lately my pump has been acting funny, but it is hard to tell that it is actually working now.
