Recently I've been having a weird issue with CPU temps and for the life of me I cannot figure out what's going wrong, nor which part must be failing in order to properly exchange.
New CPU and Mobo with the same cooler from my previous build. At first everything is fine, then one day about a week after build, I notice the fans wind up pretty loud, so I check temperatures. Idle at 40c. Prime95 26.6 pushes it to 75c in 2-3 seconds, climbing up into the 90's before the 1 minute mark. First I check the AIO Pump; running at 3,000 RPM. Then I feel the hoses; one warm, one cool. Check vcore voltage; 1.216 stable and 1.248v under heavy load. After this, I decided to remount the cooler.
This is where things just get strange. After I remount (and once simply after tightening) - and this happens every time of which I've remounted at least 4 times now - temperatures are fantastic! 27c idle, 58c in Prime95 blend test and 67c in small ffts, and the cooler stays whisper quiet. However, the next day, or two later, without touching anything, or changing any settings, the same issue starts. Loud whining fans, high idle, burning hot stress test.
Once again the cycle starts, check everything, remount cooler, all is well, then all goes to hell. My best guess here is CPU, but I'm really at a loss.
On another note, the core temperatures under slight load jump ALL over. Under 4-4.7% load Core 4 seems to be the biggest issue, consistently showing 50c then 70c then 50c and so on. Core 2 also does this but at relatively 1/3 the frequency of core 4. Cores 1 and 3 occasionally show similar readings but generally remain in the 50c range.
