I am looking for a smaller AIO, a 2-fan version (either 260mm or 280mm) with a wide socket compatibility. Any recommendation?

You can poke around in the Cases & Cooling sub and see what other recommendations you get there, but if you don't mind fan noise then EVGA has (or at least had) a good 280mm AiO:

Sadly it was on sale for $80 last month and that is over. Might go back down again for Black Friday but who knows? In any case, read some reviews since this thing can get loud with the stock fans. You can fan swap it. I have not seen any 280mm units outperform this thing in reviews (yet), and it keeps up with 360mm units quite often. It has been on the market for awhile so as always, make sure the mounting hardware is compatible.

Multi-core benchmarks take it instantly to 100C/260W. I do not think I can blame lower scores to the motherboard. The chip does "Max Turbo" at 5386 MHz, which is fleeting at best, but it seem capable of 5287 MHz on all cores indefinitely, at least in this benchmark. Prime95 brings it down to 4.8~4.9 GHz.

I think you should temporarily limit the PL1 and PL2 until you can get back on an AiO because the Scythe Mugen 5 isn't equipped to handle such a CPU at stock values.

Had to return Arctic Liquid Freezer 420 because the cold plate did not fit the socket. Running 13700K with Mugen 5 right now, and I do lose out some speed at multicore benchmarks.

That seems odd, the Arctic 420 supports LGA 1700.

I have to say, I am very pleased with how my new rig turned out. It was everything I wanted it to be in terms of performance, how cool it runs and efficiency and is a literal quantum leap above my previous rig. Alder Lake and Raptor Lake have a bad reputation for being power hogs, but the both of them can be easily tamed if you're willing to undervolt and or underclock. Having done both, my CPU is still blazing fast at 5.2ghz for the P cores and 4.3ghz for the E cores, yet the package power is just 180w at less than 1.2v when maxed (see my HWinfo screenshot on the previous page) and the package temp is 84c with air cooling. I call that efficient for a CPU with this many cores running at 5.2ghz. The memory controller is also top notch, offering great performance and stability running high frequency DDR5.

So all in all, I highly recommend Raptor Lake to anyone

Just noticed you already posted them!

Would you mind letting me know your BIOS setting for your undervolt/underclock settings exactly? What did you change?

I will try that. On a related note, undervolting vcore even by 0.03V tanked the performance.

It's a clearance issue with MOSFET heatsinks. Like a quarter inch or so.

Thx. I will definitely keep an eye on it!

I just used a negative offset for the voltage going to the CPU of -0.100v. May want to start a bit lower than that though and test stability using CBR23. A good first negative offset to use is -0.025v and work your way up from there. Once you do this, your motherboard's voltage output will switch from auto to adaptive. Also, in the CPU power management section you can find the PL1 and PL2 settings. I put those at 220w each respectively. Now as far as the underclocking goes, you just have to find where the ratio section is in the overclocking section and manually enter whatever value you want for the P cores and or the E cores.

I set mine to 52 for the P cores which corresponds to 5.2ghz and left the E cores at default, which is 43. Raptor Lake is the easiest CPU I've ever tuned bar none.

 

[Carfax83]

Yeah if you want to keep default clock speeds, then you can't undervolt too much. Might be better just to lower the PL1 and PL2 values. My CPU is clock limited to 5.2ghz for the P cores all core boost so it doesn't bother me. The performance gain from 5.2ghz to the stock 5.5ghz all core boost is marginal, especially if you have a 4K monitor and you're totally GPU bottlenecked.

But the reduction in temps is huge. My CPU after 10 minutes of CBR23 loops is around 84c at about 1.18v and this is on air cooling.

 

[lopri]

BTW these are easy CPUs to tune because they are pushed to max out of factory. There isn't much you can do. Unlocked multiplier has absolutely no meaning with current crop of AMD and Intel offerings. BClock tweaking is a luck of draw. Memory divisors are obscure and even memory controllers are pushed to max out of factory. (see how impossible to clock Infinity Fabric)

The most an end user can do is brute-forcing cooling. Quite boring if you ask me.

I agree completely. I'm happy about it though because it means less time spent messing with voltages and doing stress tests.

What CB R23 MT score are you getting with your current settings? My rig is simply set with a 175W power cap and everything else on auto. CB R23 is 34,600.

I uploaded screenshots on the previous page. Single run CB23 yielded 39,233 and the full 10 minute loop yielded 38,539. This was at 220w.

What clock speeds are you getting at such a low power cap?

 

[coercitiv]

He can if he uses V/f point adjustments. In fact one can overclock with higher voltage AND undervolt at stock clocks at the same time.

You might want to consult with some others who own your board to find out if other AiOs have clearance problems due to the cold plate. Honestly I have no idea if the EVGA 280mm unit will be any better or worse in that regard. It's probable that all of Arctic's AiOs will have a similar problem if they all use the same block as the 420mm unit. Other manufacturers may fare no better.

PL1/PL2 set to 175W everything else auto. CB clocks are about 4.7/3.7 during the run.
What are your max temps during the run?

Wrong Thread..

At the time it was 78c as I had the heat turned off in the room where I keep my PC and it was cold that day. With the heat on though it would have been 84c.

Your case is holding your CPU back because if I recall correctly, we have the same heatsink. The Noctua NH-U12a is a really good heatsink for its size but it needs a good case to get rid of the heat energy it removes from the CPU quickly.

Just got the following
Gigabyte Z690 Aorus Ultra DDR5
Gigabyte Aorus 2x16 DDR5
Intel i7-13600K
Lian Li Lancool III
Noctua NH-D15

bringing forward from my old build
Nvidia RTX3070
Seasonic Platinum 650W
Samsung 980 Pro 1TB

Should i be nervous about the PSU? Dont really feel like upgrading it. this thing has been a beast.

Your PSU will be fine with that rig. Upgrade later if you buy a more power-hungry GPU.

You have a CPU to update the BIOS or does that mobo support CPU-less updates?

 

[evident]

Gigabyte boards have a feature called Qflash plus... put the bios on a flash drive, stick it in the designated port. press a button on the motherboard when its off with no cpu or memory installed. an LED will flash for a while and then turn solid when it's done. really foolproof.

Your PSU will be fine with that rig. Upgrade later if you buy a more power-hungry GPU.

Thanks for the input.

Also I was totally set on getting an MSI Z690A and DDR4 but there was a newegg deal a few days ago for the gigabyte board and the DDR 5 for $300, which made it the same price or a little bit cheaper. seems like the Gigabyte board also has more features than the MSI one at that price point. I think DDR4 and DDR5 are at price parity especially with these bundle deals coming.

 

[Pneumothorax]

I'm building out some 13600K builds and noticed some significant discrepancies in the Core VID's. I have one copy in a Gigabyte Z690 motherboard that has a Core VID at 1.40 at 5.1ghz and another copy running in another gigabyte z690 with a Core VID of only 1.25 at 5.1. Is this silicon quality differences as the lower core vid chip runs much cooler with the same thermalright peerless assassin cooler?

 

[Tech Junky]

discrepancies

It's called silicon lottery. There are variances from chip to chip.

Hey!

Can someone help me with undervolting my 13900k
i did undervolt using Intel XTU ,but temps are stil high. Current vCore offset is -0.07V , power limit 220W Pcores - 57 56 53 Ecores 44 44 44 44 43

also, is it oke to run 13900k on 220w with -0.07vcore offset and with clock speed i mention ?

Temps are over 85C in cinebench, in corona render a bit lower...
