MSI MAG CoreLiquid P360 Failure – Same Defect as 240R/360R Recall, Just Months After Warranty Expired

[satori.ku]

Hi everyone,


I own an MSI MAG CoreLiquid P360. A few days ago, it failed. One of the tubes is much hotter than the other — a clear sign of severe coolant flow blockage. Without even opening the unit, this is a 100% classic symptom of sediment buildup inside the loop.

MSI officially acknowledged this exact defect in 2022 for the MAG CoreLiquid 240R and 360R models, and even launched a global replacement program (recall) for them. The root cause? Poor soldering quality in the radiator leading to manufacturing residues breaking loose, circulating in the loop, and clogging the pump.

The P360 shares the same design and manufacturing traits — meaning it suffers from the same fundamental flaw. The difference? MSI has not included the P360 in the official recall list.In my case, this failure happened only a few months after the warranty expired. But let’s be honest — this is not just a warranty issue. This is a hidden defect (latent defect) from the day the unit was manufactured. It’s not “wear and tear” or user error. It’s a flaw that MSI already admitted exists in their production process — just not publicly for this exact model.

So my questions:
1. Has anyone here managed to get MSI to replace a P360 with a V2 model (which, notably, was released to solve this very problem)?
2. Any advice on the best way to push for a goodwill replacement?
3. Are there any MSI reps who can explain why the P360 wasn’t covered when it’s clearly the same defect?

This is less about the warranty period and more about a manufacturer’s responsibility to correct a known defect.
Any ideas or experiences welcome. Thanks in advance.

The P360 shares the same design and manufacturing traits

How do you get the conclusion?
Do you see other people reporting the same problem on P360?
I see 360R V2, K360 V2, not P360 V2, where did you find it?
All in all, I don't think there's so many conspiracy theory out there. You might just be unlucky the product wear out right after the warranty period.
If it's only few days, weeks away from the end of warranty, I believe MSI should cover it "if you talk nicely"

The test is simple and irrefutable: one tube hot, the other cold.

• It’s not the pump — power draw and motherboard sensors confirm it’s running.
• It’s not the fans — RPM is monitored in HWInfo.
• It’s not the radiator — no leaks, no physical damage.

The only scenario where heat enters through one tube but never returns through the other is a physical blockage in the loop. And in a sealed AIO, that can only come from internal residue/sediment — a known manufacturing defect.

If it were anything else, the heat distribution and fluid circulation would behave differently. Since they don’t, all alternative explanations collapse.

Ignorance, in this case, is quite bold… not the conspiracy theory.

Thanks for sharing. You actually convinced me more, as it made me walk through a logical reasoning process. By calmly analyzing and ruling out each component, the conclusion stays the same, though I appreciate the chance to revisit it.

I already contacted MSI Spain via live chat, but they refused, saying it (MSI MAG CORELIQUID P360) was “not included in the replacement programs.” That’s why I came here, looking for alternative ideas. In the end, yes, I could go live, analyze, review, and show it’s a blockage in the loop, but I don’t think that’s the nicest approach. I also wanted MSI to be aware that another user is facing this issue, in case they wish to build loyalty and solve it proactively.

if your theory is correct, every cooler with "one tube hot and the other cold" has the same problem and all deserve a global replacement program or life time warranty.
I guess you're not here for help, good luck with the RMA.

Sure! It’s noticeable the difference but if you want to troll, it’s ok I guess

Did you ever get a resolution for this. Mine is showing identical symptoms after getting the V1 replaced through RMA, MSI has basically told me to kick rocks despite it doing the exact same thing.
