is this temperature curve (with peaks of +10°C a normal curve)? is this symptom of bad temperature sensor?
I see this running 3DMark "Fire Strike Stress test" (result 99.8%)
Ryzen 1500x + arctic MX-4 paste
MSI B350 Tomahawk
Ram Corsair Vengeance 2x4GB 3200Mhz
Sapphire Pulse RX 580 8GB
SSD EVO 850 Samsung 500GB
Seagate Barracuda 2TB
Thermaltake SE 530W
Windows 10 Pro 64
All drivers + BIOS updated (no new driver available at the moment 27/01/2018 15.50)
Thank you all
That's a normal Ryzen curve. Don't ask me why, amdmatt might be able to tell you why that happens, but I see the same thing on mine when I'm doing any kind of heavy work.
