I have a custom loop containing a Barrow D5 pump and glass reservoir moving approx. 350 l/ph. This runs through a Bykski water monitor and then feeds an AMD Radeon RX580 water block by Bykski, then an AM4 Ryzen 9 5950x cooler by Bykski then through a 240x40mm copper rad and a 360x30mm copper rad before re-entering the reservoir. Now, My temps in the system are as follows. Water temp: 30c GPU: 30c CPU: 70c. These are at idle with approx 2% CPU usage. This is after replacing a Freezemod cpu cooler which was showing 79c at idle. So, I gained some cooling with the new CPU block, but even at the reported temps, the metal CPU block feels as cool as the rads, tubing and reservoir. Is it possible that the CPU diode or whatever detects the temperature is off and if so, How would I take a true reading? It makes no sense that every thread I read, most report an idle temp within the 30-40C marks and those are the temps I have in the whole system except for the CPU. My Motherboard is an Asrock X570 Phantom Gaming 4. I have even tried curve optimising, several times, but it would seem that I have a bottom of the batch CPU, because every time I attempt to run it, at some point, my system ends up BSOD. So I have stopped trying. The thermal paste is Noctua NT-H2 and was just replaced last week when I installed the new CPU block. Oh, and the CPU block was lapped before I installed it. Checked with a razor and it is completely flat. Now, I will add that this CPU was not always this way. It seems to have gotten worse after the curve optimization had a catastrophic failure. When I first purchased this CPU, I downloaded Ryzen Master to do a curve optimization on it and lower the temps. I have never overclocked it as I wanted the lowest temps. I could achieve. So, I ran the curve optimizer on a core by core basis and ended up with most, if not all of the cores at -30 for running voltage. Then a few months later I had a bsod. Rebooted and everything was defaulted. This was when I noticed the temps were way up. I tried the curve optimizer again and it will not complete, crashing me to bsod, or locking. This is EVERY time I run the core by core Curve Optimizer. I believe I got a CPU that should have been an 8 core, due to major core instability.
Any and all help would be appreciated Thank you,
