Hi, after lots of research on these board (thanks) have spent the weekend building a new rig with the following:

i7 12700k
Liquid Freezer II 240
MSI Tomahawk Z690 WIFI
Lancool 215 case
32GB Viper Steel Ram
Old (for now) 1050TI GPU
M.2 500GB SANRIENT ROCKET

System boots into BIOS, fans all work, but in the BIOS page the core CPU temp shoots up quickly to the point the motherboard send the warning (at which point I ams shutting down) by which time it is in the 90s. Have loosened off and re-tightended the cooler block, but still the same. Any troubleshooting tips? - thanks

Did the AIO come with an LGA1700 adapter kit? Alder Lake is a different height to previous CPUs....

From the instructions on the Arctic site, it seems the liquid freezer II comes with 1700, but I guess it's a good shout in case it was an older model that came without it?

As for the pump, you should have a cable going from the pump into one of the PWM headers which looks like a fan speed, then you'll have a second cable presumably PWM from the fans, so as long as you see RPM being reported from the connector from the pump you can be sure it is running.

Yeah, that was my thought. Would explain it not making proper contact...

I'd expect if it does have it, there'd be a big ass sticker on the box proclaiming it.
 
UPDATE - after reapplying the thermal paste and tightening it all back down I seem to be settling in mid 50s whilst in BIOS - no idea if that is about right or not. Still not 100% sure about pump speed as the mono is not reporting it (have tried to set pump speed to 100% regardless of CPU temp). Anyone using this could share how they have set up in BIOS would be most appreciated (I'm am using an MSI z690 BOARD), Thanks for the help so far
 
Did you remove the thin bit of plastic from the copper part of the pump? I actually left this on my Freezer 2 and it was throttling hard. Wasn't until i removed the block to see my mistake.
 
Mid 50s idle still isn't right, mines sits at that under load in games.

I don't believe there's a way to specifically change the pump speed on the new Arctic Freezers. It's based off what the fans are set to as it's one cable to the CPU header.

Edit: Looking online someone got an official response from Arctic. Fan speeds of 40% or greater will lead to the pump running at 100%.
 
CPU’s do run in hot in bios as it runs at full speed and full voltage but I would assume the pump pwm is running the low or you left the plastic cover on the block
 
In the Bios my 12900k reads the temps a little higher than windows does. Around 35 were Windows idle is somewhere between 27-30. All my cpu's have been like that over the years. Also i have been in there a lot recently overclocking the cpu and ram. It's a dark art learning these ASUS settings these days.

Let your system idea for 10 mins and tack a temp then let it sit in bios for 10. They run hotter but I’m not in the 90’s I was just point out.

There's very little difference in it, I wasn't talking about 90c temps either. The point is it shouldn't even be idling in the 50s in the BIOS unless his ambient temps are 30+ so stating that "CPU's run hot in BIOS" just seems incorrect.

Thanks for the further comments, haven't had much time to progress anything the last few days but will pick up again on Friday - first thing I will do is check the fan speed profiles - they may be running to low which in turn is keeping the pump running low. Will update in sure course!

do you remember removing the plastic cover on the block before mounting
 
Using the same chip and motherboard here.
Updated the BIOS, and all to default, only applied the XMP for my RAM and adjusted the cooler fan curve.
Using the NH-D15S (easier to unlock the GPU when needed), maximum temperature was 72C on benchmarks.
True, loads of fans and the O11 Air Mini helps, but even the 240mm Arctic Freezer should return much better thermals.
I'm quite sure the required mounting kit is missing or some serious error when installing it.
