X370 Taichi hot hot hot

Whitecrawler wrote: It all started last night. My wifi adapter wasn't connecting, so I restarted to remedy the issue. Upon restart, I noticed my SATA hdd and Blu Ray drive weren't recognized. Booted to UEFI, no SATA drives there either. Opened case to pull drives to test in different PC, hand slipped and touched the X370 chipset heatsink. Lava hot. Literally burnt my hand. Drives worked fine in other PC. Waited for Taichi to cool over night. Started it up, drives found! Opened HWmonitor to check temps. Everything looks great for about 5 minutes, but then mainboard instantaneously jumps from 38C to 105C! Opened ASRock utility, says all temps are good. Restarted, SATA drives missing again until cool down. Been running a 3.7ghz overclock with RAM at 2933mhz for almost 3 months without issue. Hoping the new case and overboard cooling I ordered off Newegg solves my woes. But I have to ask, is my board toast, or near future toast?

Weird, first post about something like this that I am aware of.

Some of the system's SATA ports are provided by the SOC portion of the CPU, but I don't know which ports are from the SOC and which are from the X370 chipset.

The extreme and fast jump from 38C to 105C, that has not been like that from day one, right?

If not, something has changed. Been working on that PC lately, and possibly something happened? Any chance something is causing a short circuit between say the back of the board and the case? What do your PSU voltages look like in a monitoring program, all at the 12V, 5V, and 3.3V levels they should be?

That is, unless a component on the board itself has failed, or soon to fail.

If it was my board, I would be inspecting inside the case and behind the board. Also trying new SATA data cables is a thought. But IMO attempting to cool the chipset heatsink is just treating a symptom rather than the problem.

I would reset the bios back to defaults and see if the issue goes back to normal with no overclock.
