CPU temp spiking

[ms152902d7]

Hi *,

As of yesterday, my CPU temp started to rise towards 100 C point usually constantly being between 90-100 C w/o any reason.

I haven't played around with the hardware/BIOS settings or added new hardware or software for what's worthwhile and I am not overclocking and haven't ever overclocked this system. If I look at the metrics in BIOS the core/socket is between 45-50 C, after Windoze starts they reach 100 C in 15-20 seconds.

I tried everything to diagnose the issue: there aren't any CPU resources draining processes, I even the thermal paste even when there was no sign of uneven distribution on the CPU copper piece of the AIO liquid cooler (I have an MSI MAG CORELIQUID 360R AIO CPU Liquid Cooler), checked and cleaned all the fans and they seem to be ok, updated BIOS, turned Intel Turbo off as well but still no luck.

I'm running on an MSI MPG Z490 GAMING CARBON WIFI(MS-7C73) and the CPU is an i9-10850k.

A few years ago I had another similar issue on a different system with Hyper-V adding a NIC that default configuration made the CPU crazy and it wasn't caught by process monitors or HWMON, but that is not the case now.

Please see attached. Please disregard the spike at the end. It is associated with doing a bandwidth test running on 1 Gbps

Any ideas?

That whole CoreLiquid -R series is prone to a fatal sludge buildup, you can sometimes notice this by the pump making unusual noises, like so, like so or like so for example. When this problem happens, the coolant does no longer move through the system and your CPU can quickly overheat. You will also have low performance from thermal throttling, or even overtemperature shutdown.

The little coolant that is stagnant inside the pump unit will be at boiling temperature, but the coolant in the radiator will be at room temperature, as it's not moving through the loop. The sensors (correctly) report the insanely high CPU temperature, which makes the fan control put the fans on the radiator into overdrive. But at that point, the radiator is completely decoupled from what's happening at the CPU, you might as well have ripped off all the tubing. The fans are trying to cool down a coolant up there in the radiator that is already cool.

So this cooler needs to be replaced by MSI as soon as possible.

While everything Citay states is correct, the only thing I'll note is that MSI only allows a certain serial range to get replaced......I'm not exactly sure what that range is. Hopefully your's fits into that, either way, I'd probably contact MSI.

Yeah. But even if it doesn't match their official serial number range, it would be clear that a similar type of failure has occurred, so i'm reasonably sure that MSI would replace it anyway. What's more, as was posted here, even with the CoreLiquid -R V2 series (the newer version that is not supposed to be affected), some of those can develop the problem after a while. So if you ask me, the whole CoreLiquid -R series should be avoided. I would sell that one (once it was replaced) and get a different cooler. Right now, the new best price/performance AIO is the Arctic Liquid Freezer III, plus they might currently sell off the Arctic Liquid Freezer II at really good prices.
