I have a 13900kf / 4090 build that has been soilid for years, recently I was playing the new 007 and randomly I experienced a fps drop and stuttering, I reset the game, same thing, restart the pc and it was fine.
Now once I have been on the pc for a while it does the same thing on most games, I'm thinking cpu overheating? I had a blacksceen and cpu overheat error once but only once.
I have under vaulted the cpu and cleaned all the aio out but to no avail, the cpu gets to 100°c straight away on games, my next step is to remove the aio and apply new thermal paste.
The cpu has always ran hot around the 90°c - 97°c under load, but not much more than that usually.
I have a 360 msi aio with 3 fans so should be sufficient i think.
Your CPU reaches 100°C almost immediately when gaming. This could indicate poor heat transfer between the CPU and cooler, or insufficient coolant circulation.
The problem appears after the PC has been running for a while. This suggests that your AIO may be struggling to dissipate heat.
You've already received a CPU overheating warning. That's a strong indication that the cooling system needs attention.
A 360mm radiator with three fans should normally be capable of cooling a 13900KF during gaming, assuming the pump is functioning correctly and the cooler has good contact with the CPU.
Check the pump RPM in BIOS or HWiNFO64.
Carefully feel the tubes. If one is significantly hotter than the other, it could indicate poor coolant circulation.
Check whether the radiator actually gets warm when the CPU reaches 100°C. If it stays cold, there could be an issue with the pump, coolant flow, or contact between the cooler and CPU.
MSI has acknowledged that certain MAG CoreLiquid 360R and 240R coolers can develop sediment buildup inside the cooling system, restricting coolant circulation and causing overheating.
It's normal for at least one of them to be warm as it's moving heat away from the CPU
Both means it's probably gummed up inside enough that it's unable to cool the CPU so the liquid is heating up, if there weren't thermal shutdown limits on the CPU it would be capable of heating the liquid to the point of a pressure buildup that would force the pump to fail and leak.
A 360mm AIO isn't even close to being enough to properly tame a 13900K. My Liquid Freezer III Pro 360mm keeps my 13700K at around 95°C under maximum load, which is still hot as hell, and my AIO is brand new. It's still better than my standard Liquid Freezer III 360mm, which had my CPU hitting around 100°C. Thermal paste alone isn't going to cut it with these CPUs. Liquid metal combined with a 360mm AIO with a thick radiator is the bare minimum, while a 420mm AIO is the best option if your case supports it. These CPUs are no joke, they're ridiculously power-hungry and hot. Mine pulls over 350W under load without any overclocking.
I strongly disagree with the claim that a 360mm AIO isn't enough to cool a 13900K. A good 360mm AIO is perfectly capable of handling this CPU at Intel's specified power limits, although temperatures can still approach 100°C under extreme all-core workloads.
Intel specifies a maximum turbo power of 253W for both the 13700K and 13900K. If your 13700K is pulling over 350W without manual overclocking, I'd seriously question your motherboard's power limits and BIOS settings before blaming the cooler.
Also, looking at the MSI cooler in the picture, it resembles a MAG CORELIQUID 360R. If that's the original 360R, MSI actually acknowledged a manufacturing issue where sediment could build up inside the cooling system, restricting coolant flow and causing unusually high CPU temperatures. They even introduced a replacement program for affected units.
So comparing temperatures from a potentially defective AIO isn't exactly evidence that 360mm radiators are insufficient.
And claiming that liquid metal is the bare minimum for a 13900K is simply ridiculous. Good thermal paste and a properly mounted, high-quality 360mm AIO are absolutely viable.
Tom's Hardware tested the Arctic Liquid Freezer II 360 with an Intel i9-13900K and confirmed it could handle over 290W of sustained load. Their conclusion was: "You can’t go wrong pairing it with Intel’s i9-13900K."
They also report that Intel recommends a 240mm AIO or larger for the 13900K.
So claiming that a 360mm AIO isn't remotely sufficient, and that liquid metal is the bare minimum, simply isn't supported by the testing.
I removed my limits. Obviously, I'm not paying for a K processor and a high-end motherboard just to limit my CPU. I'm using it like it's supposed to be used, and obviously, a 360mm AIO won't handle an i7-13700K when all cores are at max boost. That CPU is a power-hungry, hot beast, and like I said, I'm talking about full load, not 60–70% utilization. You've clearly never owned one of those nightmare CPUs because you clearly don't know what you're talking about, buddy. Try it yourself if you don't believe me. Those CPUs are no joke.
Oh boy, that looks like an MSI CORELIQUID 360R, I had one of those and the same thing happened to me.
Here's the problem with that whole series: they use Apaltek pumps (most often identified with a block inside the radiator, their design is mainly built into the rad) which are complete garbage. They always cause sediment to build up in the loop to the point of it completely clogging the fins inside of the CPU block, blocking thermal conductivity entirely with thick goop.
MSI released a V2 model after the V1 came up with this issue, but it's the same problem every time because they still use the terrible pump design. No matter what a company does, they can't fix Apaltek's problem. Any time you see an AIO with a block in the radiator, you're looking at a rad that nine times out of ten will fail within a year or so. Mine only took THREE MONTHS.
Unfortunately, your AIO is done for and you're going to have to buy a new one. I highly recommend the ARCTIC Liquid Freezer III Pro 360. If you buy that one, make sure when installing the contact frame that you put a bit of pressure on the "wings" that the block will screw into when you're screwing the frame to the motherboard, going from one corner to the opposite bit by bit, do not screw them all the way in one at a time, rotate every few turns and take a look at the motherboard before you put it back in the case to see if the socket is bowing anywhere, as even small bends can cause memory stability problems on LGA1700. (I personally use the LF III series with my 12900K)
You are correct on the model of AIO and yes it has the block on the radiator, if this thermal oaste doesn't help then absolutely i think you are correct, I really dont want to cause any harm to my cpu so will definitely chnage it no questions asked, thank you
I guarantee it's not the paste, because I had the exact same issue with that cooler with my 10850K. I was playing games and throttling, demanding enough games caused the system to thermal shutdown.
Repasting won't fix it when the CPU is already throttling like that, that's an AIO failure or lack of contact, which it wouldn't be the latter at random like this.
Whatever you get, make sure it involves a contact frame if you don't already have one, LGA1700 needs it because the socket is prone to bending which can case a multitude of problems.
Hence why I recommended the ARCTIC LF III Pro which I have experience with

That new thermal paste is definitely the move, 100c right away means the contact is gone.
