Question Problems with my AIO

[jasonbirder]

I've a 12700K running at stock cooled by a Lian Li Galahd 360
I have doubts as to whether its cooling correctly
In BIOS it does say its running at c3300 RPM (CPU OPT Header) but my tempretures (in HW Info) bounce all over the place really rapidly - which you would think would be damped down by a reasonable sized AIO...
It won't run Cinebench (multicore) for more than about 4 mins before temps hit 84 degrees at which point my computer restarts...
Anythoughts?

include your complete system hardware specs along with your minimum and max CPU & GPU temperatures during regular use.

The throttle point for intel is 100c. 84c seems wrong.
You may be measuring something else like the cpu package.

Look at the minimum cpu temperature for a single core.
It should be perhaps 10-15c. over ambient at idle if your cooler is mounted well and functioning.

This seems more like BSOD, but 'restart on system failure' may be enabled, so the stop code doesn't get displayed.

Also, why is it in the CPU_OPT header? CPU_OPT follows the curve of CPU_FAN. That's fine for secondary fans, but less so for the pump, except if you have a rather flat curve set for CPU_FAN.

OK...i've sort of sorted it...but its left me even more mystified!
After undervolting by -0.05v my tempretures have come down about 5 degrees.
I'm at about 10-15 degrees above ambient at idle...and I ran one pass of Cinebench multicore with tempretures topping out at c80 degrees...with no restart. (Previously it would last about 4-5 minutes of a cinebench pass then freeze and restart)
That seems to say to me that my cooling system is functioning OK...if there was a problem with the AIO i'm sure it wouldn't last 10 minutes at 100% utilisation on all cores without something nasty happening...
TBF the temps (topping out about 79-81 degrees) on that cinebench run seem within expected ranges (particularly as its warm here and my rooms about 26 degrees)
WHich raises the question...why was my computer restarting itself so often

I've got a flat 100% RPM as its the Pump for my AIO

I think one run of Cinebench is a bit too early to write it off as fixed...

Aye, you posted that you have the pump in CPU_OPT, which follows the set curve of CPU_FAN. So whatever is plugged into CPU_FAN is set to 100%.
If fans are plugged into CPU_FAN... they're rather loud, aren't they?

THey the Lain Li SL fans...they're odd they don't take their fanspeed from the mobo in PWM mode...they follow a curve from their own sofftware...

Well, that throws me for a loop. I don't, and have never used software for fan/pump control.

I'd rather not either but they don't have enough pins to be controlled from the fan headers...very strange....

There's clearly something I'm missing then. The real problem is the crashing, which 1 run of Cinebench isn't enough for - and if it was the 10 or 30 mins preset runs, those definitely aren't long enough.
