Nice, good call on the case. Good luck with your overclocking!

Yes Overall it has better airflow and since I might go with a AIO it was the best choice.. I do have a question about the AIO's, what does the 420 stand for in the title of the Arctic Coolers, I thought that menas it has 4 slots on the rad for 4 fans or I am guessing I wrong here as I was just looking at the arctic coolers and they had 3 fan on the rad and 1 for the vrm? if that is the case I am guessing go for the 420's..

The OC I got too 51 and 43 on the ring still at 40 on the ecores.. but I had disabled my HT. which did not do much for the OC.. I am still wondering what the max voltage I would want to apply on the VCore.

I am really interesed in this cooler:

Nice price and it has a VRM fan..


EDIT: It booted @53 now to test. it booted but was not stable. I went down to 52 and seems ok for now.. probally as high as I can get on air.. will look for more reviews of the above cooler but initially it looks good..

Well I found out what the maximum voltage for 12700k which is 1.7v. so I am curious to what the OC'ers think a 24/7 voltage should be.. I ask because I want to know not that I will not attain said speed on air..

 

[maestro0428]

Whats your LLC at? Yikes, 1.7v, thats a ton of voltage. Mine is set at 1.4v on CPU Vcore. The 420 stands for the mm of the fans, 3x 140mm is 420 and 3 x 120 is 360mm. The one you picked should work great, just make sure it will fit in that case cuz it is BIG. Disabling HT should let you lower temps and allow for a bit higher clocks.

No my voltage is not at 1.7v that is the max I can set it at according to Intel. I have it on 1.50v @52core.. OK I will need to probally need to see if the case I am getting will fit 3-140mm fans..

EDIT: I am not finding many cases to fit the 420 Rad. I am just going to go with a 360 and that should be fine.. I am just all screwed up with cases that I ordered and cancelled and Amazon charged me for one and it did not even get shipped. so I am going to wait until that clears from my account.. I dont want it getting shipped even tho I canceled it and have 2 cases..

 

[The_Nephilim]

well seems to be chugging along at 1.5v @52.. still have not found a reference to a safe 24/7 speed I googled and searched this forum just posts with probally bad info. but still no mention of safe voltage 24/7.. I guess I will just leave it and see what happens.. I could probally go higher but it will probally heat up real quick after I OC the CPU more..

 

[maestro0428]

1.5 is a high IMO. Mine is locked at 1.4v with 5.2 all core and 4.0 ecore. Some people run theirs even lower, but mine has been at these clocks/volts since I got it which was several years ago now. But not every chip is the same or motherboard. What are your temps like?

 

[The_Nephilim]

Well I was just running OCCT with the CPU + RAM Test with AVX Instructions it was hitting between 74-82c I was going to try and start decreasing the voltage but I know it will not go at 1.4 or lower @52.. but I can retry it but it will boot at 1.4v but test crash out..

Will try to lower a little..

 

[The_Nephilim]

Well it seemsto like being at 1.5v, I tried all from 1.45-1.5v and it was ok at 1.5v again.. I was just wondering what the reccomended safe 24/7 voltage would be? I mean if the temps are fine and I am not going over Intels max voltage it should be fine or no?

EDIT: I did find a guide and it had mentione good upto 1.52v but the limit for NON LN is 1.7v.. so I am guessing I am fine. I also read about setting the individual cores high then set some others alittle lower.. I might mess with that I will have to reread that guide of sorts found here..

 

[The_Nephilim]

OK I went back to 5.0ghz a d 1.33v. it should be good long term again.. maybe If I get the water cooler I will retry for higher.. thnx everybody

Well I am dipping my toes but it seems the question that elludes me is what is a safe 24/7 voltage for OC my CPU.. I was at 1.5v but I don't know the longterm effect it might have. noww I am wondering if going as high as 1.6v would be wise?

 

[maestro0428]

1.4 is locked on my 12700k

 

[The_Nephilim]

1.4 is locked on my 12700k

hmm that is wierd. but is it locked on the mobo?

 

[maestro0428]

Yes, I locked it to that, I could use variable voltage, but it seems more stable at 5.2/4.0 at this point mostly because I am running four sticks memory. My LLC I believe is set to 3, but I can get shot of my settings if that will help you. All settings are fully stable, but it is an ASRock board, (my MSI board is running a 12600k) as I rendered video for hours on end the last few days on it with no problems.

 

[The_Nephilim]

well I am just trying to get a good OC without breaking my CPU in theprocess. I had it at 5.2 but @1.5v some seemed to think that was to high. like I been saying I still have not figured what a good 24/7 volts should be. I did see in the whitepaper from intel the volts can goto 1.72 without LN. now does that mena I can safely goto 1.7 and OC as long as the temps are in check??

OR will going that high break something..

 

[maestro0428]

No, dont go that high. Id say 1.5v is too high for air cooling. I dont know much about undervolting, but I do know that some people are pretty good at that.
"Thanks to an unlocked multiplier (the "K" suffix in 12700K), overclocking is really easy. You can just adjust the multiplier freely in your motherboard BIOS or the XTU overclocking software.

The highest stable overclock was 5.0 GHz, at pretty high voltage of 1.4 V. Going higher was not possible, not with AIO, nor 1.5 V or more.

While 5.0 GHz matches the stock single-core maximum boost, given the results and considering the massive increase in power consumption I don't think it's worth overclocking the 12700K manually."

Well Time Warp and I have a AIO and I just ran the same test as I quoted above but the temps were in the 58-66 on the p cores.. so it was a definite decrease in temps..

I am going to see what happens with a higher OC.. maybe try for 5.4ghz.. suicide..

 

[The_Nephilim]

well I was able to get 5.3ghz @ 1.65v but it was not entirely stable I might have been good at 1.7v but I decided to lower the clock too 5.2 @1.53v it was stable there.. I am guessing this is the wall for this particular cpu but I could probally aqueak it up a bit with some fidgeting of the voltages and such but I am going to try using this OC for a whil and see how it does..

but the good news is I did get the vcore too 1.65v and the CPU did not pop.. but I figured at that high a voltage it was not good for 24/7.. I will leave it where it is at for the forseable future it was fun..
