Should i be concerned about the temp of my 13900k?

[analog swallow]

I have my 13900k installed with a 240 AIO.

Im idling at around 35-40C, drawing anywhere from 15-70 watts, depending on what windows is doing in the background.

However, when i stress test the CPU in Cinebench, it fairly quickly reaches 90-95C, and if i sustain a load on it, itll go beyond that, 95-100. Its drawing almost 260 watts at that point, which i know is a lot to ask of a 240 AIO to deal with.

Should i be concerned about this? I've already disabled the "Asus performance enhancement" setting in bios, that lets the cpu draw 300+ watts.

I havent yet tried to play around with the pump speed. That will be the next thing i try out though.

Thanks for any inputs/solutions!

240mm is definitely not enough cooling for a 13900k

You'd want 360mm AIO minimum

Either that or power limit it

You won't get full performance but at least it won't thermal throttle on you

[analog swallow]

Damn 😄 thats what i feared.
Do you have any tips as to how i go about limit powerdraw? Ive never really messed with cpu overclocking/underclocking before.

I think if i can just limit it to 240 watts or something like that, and increase the pump speed a bit, it might be alright. In everyday use and gaming nothing is going to utilise that cpu 100% anyway. Ill look at getting a 360mm AIO soon though

Adjust PL2 in bios

[analog swallow]

What does PL2 stand for if you dont mind? 😄

[noble mauve]

Power limit 2

Aka power limit when boosing

[analog swallow]

Should be under cpu settings somewhere im guessing in bios?

[noble mauve]

Depends on motherboard bios and manufacturer but most likely yes

[analog swallow]

Thank you! What would you say i should limit it to? Clearly its having some trouble at 260 watts. So maybe 220? And if i limit it at 220, would i be giving up a lot of performance?

[noble mauve]

i would say try 205 watts

[analog swallow]

Wow okay, thats not a very big performance loss. Ill try 205 watts. Thanks!

@noble mauve so in my Asus BIOS, its locked to auto 😦 i cant change it from auto. PL2 is also called "short duration package power limit" in my limited research 😄

Yeah for that 13900K you will need a 360 or bigger AIO.

Also, definitely worth installing a contact frame to get the absolute best surface possible for heat transfer.

[analog swallow]

Thank you! Ill definitely look at getting a good 360 AIO

[ocean wolf]

If you shoot for a contact frame, it looks like the Thermalright frames is going to be your best bet.

[analog swallow]

Ill look it up! Never heard of contact frames before, so will have to read about it for sure! 🙂

Here. You just need to watch the first 10 minutes or so.

Thanks a bunch! 🙂

Figured this out, just had to write 205. There was no indicator that i was able to write though. Should be limited to 205 watts now. Will test if my temps are alright for now

Hmm, i just ran cinebench for about 5 minutes, and my computer shut off after about 5 minutes. The package temp never rose above 90C though 🤔 and it was only drawing 205 watts as i set it to.
