Have Threadripper 1950x on ASUS ROG Zenith Extreme motherboard with liquid cooling system. In usual case there is no issues with the temperature, average 30-35 °C.
But sometimes when Windows 10 x64 goes to a sleep mode, CPU temperature becomes very high (90-95 °C) and system doesn't response.
BIOS is the latest v0701, CPU is overclocked to 4.0 GHz. In the attachment CPU-Z report.
