I recently replaced my motherboard, cpu, and memory, getting a 990fx ud3 from gigabyte and an fx-4300 cpu. In bios and in every hardware monitor I've ran, I get cpu temps as low as 4 degrees celsius, which is ridiculous. I can run prime95 and almost get it up to 30, and then it immediately drops down to around 10 degrees once it's shut off. Using the Dark Knight II Night Hawk Edition cooler from Xigmatek. I tried using a different cpu and got the same problems, so it's looking like it's definitely a mobo problem. What do I try next?
