I have an msi z690-a pro wifi motherboard.. i've had a hard time so far getting this to be cooler with the aio x73 kraken and ddr5 c40 5200mhz corsair.

although at this point i think the issue is the "watercooler" setting in the bios, i think changing to boxed will lower the wattage limits and make it better. I'm going to retry with this change later on and see if that brings this down.

I have it at 5.1 fixed and 3.9 and 3.9 on the ratio along with bios volts around 1.28v and llc is tight, i think 2 or 3. Cinebench will avg 88 but hit 100c at times.
What ratios are most setting and what voltages on average do you end up at.. obvious voltages can vary but trying to get a ballpark on things.
Thanks in advance

These CPUs can get hot if you allow it. 1.3~ will pull nearly 290 watts at 5.1 GHz if I remember correctly. I do my VRM stress tests at 5Ghz 1.35 and it is usually around 330 Watts for just a 12700K. A higher LLC will put more voltage in as well. Open HWinfo and see what the power draw is. You may need to lower the OC or delid the CPU.

Edit: This is my voltages I use but it greatly depends on the LLC and how good your CPU is in the first place. Mine is very well binned.
CPU-P / CPU-E / Voltage
54 / 41 / 1.35v
53 / 40 / 1.3V
52 / 39 / 1.25v

CPU / RING / Voltage
54 / 41 / 1.35v
53 / 40 / 1.3V
52 / 39 / 1.25v
Thanks, so are these for the 12700k, not the 12900k?
Still useful as a reference. Are those bios voltages or load?

I couldnt run cinebench when i had tried a cinebench load voltage of around 1.255 or so, it threw an error, i think i may have had the bios 1.275 at llc 3ish (msi more loose bigger num) , i was hoping i could do 1.25, i guess my chip isnt a great chip.. i think it probably rings in at 5.1 round 1.285-1.30 with tight LLC2ish. I havent tried 5.2, but im guessing if temps are high at 5.1, 5.2 wont be better haha.

Both really. But these are from the 12900K actually. They are the voltages I input into the BIOS. So it will be lower under load because of the vdroop (for me).

Sorry I didn't mean ring. Its E-core (Atom cores). Ring needs to match the atom or be lower I believe. Unless you disable the E-cores.

With MSI, they push the shit out of things without being set to boxed cooler. Thermal issues are due to that alone.

Test both without a manual OC on the CPU and see. It's very clear.

Just for reference, prior to changing to "boxed cooler", i confirmed it shows 4096w in hwinfo

prime 95 blend package levels are at 261 watts max, avg 85-87c, peaks to 100c, 1.270 volts or so loaded
cinebench is at 241 watts (27,423 score), initial 84c, then within seconds 100c, avg 85-87c, 1.264 volts or so load

real world photo / integration render, peak temp of 92C (i dont think it was using avx, which i have at -2)
I think i have the bios around 1.285 or so and llc3 but need to confirm

I did test while still "watercooler" setting, i had the ratio's at auto and voltage at auto, temps still spiked to 100c, will be trying the boxed mode soon.

Had the same thing on my MSI, anything other than boxed shot temps to 100c.

12700K. 1.35V @ 5GHz. This was only possible after deliding the CPU. Hovers around 96c~ in Prime95 max power. Unless you have the means to cool these CPUs I would just leave P1=P2 at 240w

well, changing to boxed type didnt help alot.. though cinebench at first didnt hit 100c, but 97c instead, eventually it did hit 100c, i confirmed i had the bios set to 1.29v and llc3, avg cinebench maybe 83-84 instead of 85-87, watts went from 241 to 227w for this test.

I guess ill still consider lowering from 5.1 or trying again to lower volts, or still do the washer mod.

WHAAAA? 1.9V!!!!!!

Also have you tried just seeing what the performance is of stock. You may not gain anything worth the trouble. Just depends on what your doing.

Washer mod is dumb. You'll end up in a worse place. Those 3rd party brackets will be better but it also requires tinkering to get the tension right.

even at 1.22 load and 5.0ghz (bios override mode, LLC2), i still hit about 96C on the cinebench after a few mins (avg maybe 80c).. also, if you change the ratio, it tries to switch the mode back to watercooler from boxed to the full 4096w
1.25 load was more like 83c but 98C or more (at 5.1ghz)
5.1ghz and 1.22v load/bios was bsod.

What would stock be defined as? Box cooler mode + auto on ratios and auto on volts and auto on llc?

Auto CPU everything. Cinebench R23 will be around 27K. Full OC of 5.4Ghz gets very close to 31K. Gaming...IDK. run some benchmarks and find out.

Yea I have done that at least with the watercooler 4096 mode, Temps shot to 100c at times

Well thats not normal. You should be around 80c~ unless your manually overclocking because your voltage will be around 1.15v-1.2v on auto.

Remount the cooler, make sure that isnt the actual problem.

I may remount tomorrow,

I did make one small progress, sort of, setting the bios to offset, negative 0.030, this seems to ring in at 1.30 or so under NO load and about 1.22 or 1.20 under cinebench load and its somehow surviving.. this at 5.1ghz / 3.9 again and boxedcooler wattage. Max temp now at 92C, avg 78C. When i tried 1.30 LLC4 override, i was getting about 96C under full load (vs 100C if i left it at watercooler mode). So the boxed mode helps by at least 4C no matter what.

Im puzzled by making it even 5 mins into this test with offset and load of 1.20v, i tried a manual llc2 (tight) at 1.23 even and had issues with bsod or cinebench errors. With the offset, idle it will hit 0.66v

It would have been nice to have 5.2ghz here, but if this pans out on 5.1 ill leave it be. (i guess ill try occt small variable no avx and maybe overnight on prime95 blend no avx)

UPDATE:
Well i did put the #6 washers on just now (managed to find locally), changed the thermal grease, noted that half of it was pushed to the side somehow last time (mx5), went with mx4 this time, did 5 dots, x pattern, one bigger one in the middle.

Same settings again, so far in the same amount of time as the last test before, it hit 90c, last was 96c, avg 67-76 (p95 blend avx2 is still on), minutes later its still only at 93c. So id say there is a 4-6C drop from the washers (or from redoing the paste)

side note: Im still having the issue that i had with the non wifi z690-a msi board, where if you change the ratios to any other value, you lose the nic lan in windows, error 10, have to shut off and hold in power button for 20 sec and wait a few mins.. however even after redoing the cpu cooler/washers this time, i still have no lan card working this time

From the picture it looks like half the IHS is not making contact.

Edit: From looking into this washer mod, I think the real problem is the backplate. So many are plastic these days. I had zero problems using EKWB waterblocks because they all have metal backplates. Your probably losing connections because the CPU isn't making proper contact with the pins.

Ah this is true, the lga1700 i got off amazon is plastic, i think the official one is plastic too. Well either way its improved now, quite a bit, even put the case on during this p95 blend (with avx2) test, 94C has been the max, 81c now the average (case adds 1-2c, that was obvious but i wanted to see).

Im still running the 1.30 LLC4 with -0.030 offset i tried earlier, i forget if i have the it on watercooler 4096w or boxed 241w , its 5.1/3.9/3.9 ratios, 5088 or similar reported max in hwinfo. The load is as low as 1.13 during p95 with this arrangement. (as i typed this it went up to 97C, still under 100c, case still on though so plus 4 with that, good to know, still ok relatively speaking)

Part of me is curious if the paste is offset again but if all this holds, im leaving it as is, 5.1x etc.z

EDIT: so far everything working great, my gaming/vr msfs temp only hit 73C.

It's not so much paste being pushed to the side, it's the cooler not making contact on one side. Mounting issue. When you remove the cooler, the paste should be even across the whole IHS.

With 20c ambient a stock 12900k with a u12a gets up to around 76c peak. Its never hitting the power limit in cbr23, it hovers around 220 watts. The best i can do for cinebench was 5.1ghz and a score of 30k with the cpu peaking at 91c at 270 watts.

If you have similar ambients and you end up with higher temperatures with your 360 aio something is not right.

So i had about 10 hours of successful prime95 blend with avx2.. max temp 94c during the period (side of case off, otherwise would have been 2-4c higher i think): (this all post washer mod and repaste with mx4)

summary of settings/results:
xmp with vddq at 1.35
ram volts at 1.35
ram speed on auto but at its 5200 mhz

Ratios 5.1/3.9/3.9
Offset mode negative and 0.030
Cooler set to "boxed" 241watt mode

Gaming max temp (MSFS/vr) : 76C (case panel off)
P95 blend 94c 10 hours (i think the draw was something around 1.2v or maybe a little less)
Cinebench r23 10 min morning test today: 83C max temp this time, 241 watts used, 27085 score
OCCT small without avx was hitting around 94c i think (at least last nite)



So at this point id like to figure out a few things.
I saw some posts about folks getting under 200 watt power draw, unsure how that is achieved.

I see many posts of up to 5.4ghz and similar, i'd also want to take a shot at at least 2 cores being 5.2 and maybe the ecores at 4.0ghz ..

**i tried initially leaving everything the same and raising to 5.2 on two cores, i found the volts on loading windows were 1.42, way too high.. unsure why the voltage rose with same offsets.

I tried a higher 0.08 offset but that didnt seem to bring the under load voltage down, more like 1.3v
Confused on that part.. also confused because in the past i swear you could enter a voltage like 1.30 and then set its offset, not just have the offset, seems the bios picks its voltage on boot up, i did notice a 1.40 or similar after changing ratios, i guess that is an indicator.

two cores at 52 is stock turbo. You aren't getting anything extra that auto wouldn't do. If you are getting 27K in R23, that is a stock CPU.

I now have ran with offset 0.03 negative.. and 5.2 ghz all core, 4.0 ecore, 4.0 ring, llc4 its about 1.15-1.16 again with small ffts, avx is set to enabled and -2, box water type cooler 241watt max
P95 will hit 90c after about 10 seconds and not exceed 94 on small ffts over 1 hour. Cinebench averages 73C with a max of 83c

After all this, i tried cinebench r23.. i only got 27,400 for a score.. and realized in hwinfo, the max cpu speed is only 4888.0 mhz..

So i tried setting it back to the 4096 watt watercooler setting, sure enough, it was ringing in at like 5099 for the frequency on the pcores and the score was more like 28,400

So much data i've looked at at this point, im pretty sure others with the 360 type coolers were staying 95c or less and getting 28,500 type scores (or even had avx on 0).

So i guess either my cooler is still not sitting evenly on the chip, or in my situation/chip i just cant use the watercooler setting to boost the avx mode any and have to settle for what i get.
Or i dont get how people are getting 28k + scores with r23 and not hitting 100c during the test with the 4096w limit set (and about 5-5.1ghz avx mode)
