My 2700X is getting up to 115ºC Tctl and then shutdowns itself even at STOCK.
- Cooler is h115i (Water temp 30-40ºC)
- Board is Crosshair 6 Hero and 6101 BIOS
Does Corsair LINK backup those readings? Under Prime95 stress and even the pump on quiet my slightly OCd 1800X barely hits 70.
There was another person on here with an overheating problem, Does the Ryzen 7 2700X run HOT? which turned out to be a BIOS problem, and I'd say a reading of 140*C is either a sensor glitch or reading glitch which is throwing off the other readings, especially since Corsair has long since compensated for the offset temperature and matched the package and CPU temperature readings in their software, as well as AMD having corrected Ryzen Master's temperature readout.
I don't care about what number it shows, I care about that number affecting my CPU so the system Shutdowns. Last BIOS, last everything and Ryzen Master shows also the same high temperatures.
Everything in stock the CPU lowers its speed to 3700Mhz because of that and still reaches 90ºC or more.
Reflashed BIOS, Clear CMOS, run stock settings....
I think this CPU is broken.
Where did you get the last BIOS for your Motherboard. According to Asus the latest BIOS version for the Crosshair 6 Hero is: ROG CROSSHAIR VI HERO Driver & Tools | Motherboards | ASUS USA
BIOS - Version 6004 - 04/19/2018
AMD Chipset - Version 512038 - 02/24/2018
Found this post from Tom's Hardware Forum about the CPU watercooler you are using also causing the CPU to overheat. It is old but may still help you find your problem: Corsair watercooling H115i installation - cpu overheat - [Solved] - CPUs.
