Fans suddenly run at 100% and computer shuts down

[GoeGad]

Hi!

I bought a Lafité Pro 14" some months ago, but first now I have begun to configure it.

I think I have the same problem as discussed here: https://www.pcspecialist.co.uk/forums/threads/fans-keep-powering-my-machine-off.80664/ Unfortunatley, there is no conclusion in that thread.

When the computer is idle, the fans sometimes go from 0 to 100% abruptly. After one minute or so with the fans running like jet engines, the computer is shut down in an uncontrolled manner. No BSOD, no orderly shut-down procedure, just blackout. The computer does not even feel hot. Why does this happen and what can I do about it?

I have installed HWMonitor to log the temperature, but I haven't been able to see the temperature at an unexpected shutdown. When running HWMonitor the fans sometimes rev up gradually to bring down the temperatures from 91°-94° C to around 50°. I don't know why the temperature has risen in these circimstances, but the behaviour is what you would expect, not a total blackout. Obviously temeperature management works properly sometimes, but sometimes it seems to panic without reason.

Some observations:

• The fans don't run when the display is off. If I lock the computer (Win+L) the screen will go black after a short time, and soon the fans will go silent even if they have been running quite fast.
• There is nothing special to see in Task Manager when the fans start running like crazy. CPU and memory are on 10% utilization. The computer does not feel hot.
• I left the computer overnight with nothing more than HWMonitor and Task Manager running. In the morning it was still running, lid open and display shut off, no audible fans but quite hot. When I logged in the fans started cooling at almost full speed. HWMonitor displayed CPU temperatures around 95°-99° C. I enclose the log. At this time the computer really felt hot, but the fans managed to bring it down without any crash.

What is happening here, and what should I do to make the temperature handling work properly?

My best advice would be to Phone PCS and tell them the issue and that you will be sending it back to them to have is checked out. You paid for a Gold Warranty so I would use it. ( downside to this is you would be without a computer for a bit ).
