Do you mean at the top of the mobo where you have the standard 8 pin ATX connector from the PSU with an additional 4 pin one next to it? That's the 12v EPS connector and is optional. It's only needed for very high power requirements from say a 2nd GFX card or extreme overclocking. I plugged mine in anyway but will be disconnecting it tonight when I'm fiddling about with the AIO fans.
 
Two 8 pin on the top of the MSI board (numbered 1 and 2), only going to be using number 1.
TY for the power usage info mrk.

No manual with the MSI board bit peeved with that, are all the new boards supplied now without manuals?.

LOL I got a CD with the MSI Motherboard and no manual.No need for either in 2021.Have not had a CD player in 10Years
The MSI cheapest one to buy is quality board all around and does all what the expensive motherboard can run at and exceed them as of today.

EG: Dual Rank Gear 1 DDR4 CL4000MMhz Sub timings not even tuned cause no need
 
No manual with my Gigabyte board either and their website doesn't even have a manual to download, only a quick start guide and BIOS guide which is seriously annoying as I've had to faff around finding stuff out myself through trial and error lol.

I've done some more tweaking to my build btw, The Freezer II's fans have been disconnected from the in-line cable which connects to the pump and VRM fan, the rad fans are now connected via a Y splitter to the CPU_FAN header on the mobo, and the pump/VRM power cable is connected to the SYS_FAN4_PUMP header on the mobo. I had to use some PWM fan extensions to get these cabled up as Gigabyte decided to put all the non-CPU fan headers right down at the bottom right of the mobo so naturally normal length case fans in a case like the 5000D won't reach without an extension if you cable about tidy cabling.

I also disconnected the EPS 12v connector and left it tucked behind a velcro cable tidy in the event one day I get a new GFX card that requires the extra power (RTX 40 series???).

With this new config I've noticed the idle temps of the CPU have dropped back down to 27/28. I guess it's a combo of the extra EPS connector being disconnected so there's less heat being generated around the CPU by the power regulators, as well as the rad fans being run independently to the pump which has its own stepped speed curve in the BIOS so no longer runs at the same PWM % as the rad fans like it did before when they were all connected to the single AIO connector to the CPU_FAN header.

I may just change the pump's speed to a set constant like 50% only until the CPU hits 70 degrees at which point it ramps up. This keeps the pump running at a constant rate at all other times only speeding up when all cores are maxed.

It's been fun though, been 5 years since I pretty much rebuilt the main PC. Learned a whole bunch of new stuff the last couple of week :cool:

Just a side note for all those with a Freezer II that might do the same thing, the VRM fan and pump do not report any speed via PWM, so don't expect to see any RPM readings in BIOS or in any software. You'll know it's working though as you can see the VRM fan spinning through the side panel window.
 
Used the AI Asus o/c thingy to set my 12700k/Freezer 2 280mm up, some cores at 5.3 some at 5.2 and allcore at 5.1 which isn't too bad at 1.34v. Not golden but not awful :)
 
I will not be OCing tbh, don't really see the point when chips nowadays are so powerful at stock. There isn't a single game where all modern flagship chip models are a bottleneck. Even at 1080P we are now GPU bound!

Forze 5, Metro Enhanced, RDR2, Cyberpunk, all of these games for me barely scratch the CPU utilisation and they are multi threaded games that share the workload across all cores.

I'll keep my fans on near passive silent until things change :D

I'm quite overwhelmed overclocking the 12900k probably don't need to?

Set turbo core ratio and then adaptive voltage,then AVX off set done. If you want actual setting I done up two different BIOS settings with adaptive voltage,quick and easy to follow.Not the complicated crap some people are talking about.
 
Is it necessary to clean install Windows after upgrading the CPU and Motherboard? It was already a clean install on my 9900K and seems to be working fine so far with 12700k.

Ah!, if you can disconnect the fans from the pump that will let you flip the fans over on the rad from push to pull, meaning if fitted to the front it would suck air in. (through the dust guard).

I don't have the clearance to the MB to fit in the rad/fans to top mount, just room for 2 fans to push air out of the top.
