Question AIO dead?

[legio1_x]

My CPU is overheating when under no particular burden. Note that this setup has been stable for 3 years (did have a GPU upgrade 2 years ago) so for this to suddenly happen today caught me off guard.

What happened in detail:
This afternoon I noticed a slowdown. I wasn’t doing anything hard at the time, just web browsing. At the time I thought I simply had too many tabs open. Within 30 minutes the slowdown was unbearable (e.g., opening a folder took several seconds to populate). In hindsight I should have registered that the fans were spinning frantically but at the time I didn’t. Instead, I rebooted.

After the system booted I got a high cpu temp warning. In disbelief I opened Hardware Monitor and got to watch the cpu temp tick over from 105c to 106c. Naturally I shut down. Not having any great diagnostic tools available, I immediately grabbed the IR thermometer from the kitchen and took temps from various parts of the AIO and the system as a whole, hoping to get some idea how heat was moving thru the system. Recorded temps are below.

Max reported cpu temp: 106c

Values measured with IR thermometer

• AIO top of pump: 37c
• AIO radiator fins: 27c to 29c
• AIO water line #1: 43c
• AIO water line #2: 39c
• Other parts (gpu, memory, etc.): 21c to 24c

The massive delta between the water lines (measured thru the insulated hose) and the radiator fins led me to think there was a blockage preventing the coolant from circulating (i.e., AIO is dead). But, as I said, I’ve only ever used air cooling before so I’m hoping for advice from someone more experienced with AIOs.

Key system components:
OS: Windows 10 Pro
CPU: Ryzen 5 5600
CPU cooler: MSI MAG CORELIQUID R 84.36 CFM Liquid CPU Cooler

I believe that particular cooler is known to fail.

MSI Issues Recall for MAG CoreLiquid 240R and 360R AiO Coolers - Sediment Build-Up

MSI is recalling its MAG CoreLiquid 240R / 360R AiO coolers due to the possibility of a blockage occurring in a "small percentage of the liquid coolers." ...

They had a recall.

Clearly the AIO system is NOT removing heat from the CPU fast enough. I'm guessing the rads fans are all working well. The temp difference between water lines indicates there is SOME fluid flow around the system, but that difference is not huge. Rad temp is low, so clearly the fans are doing their job. Most likely problem is slow flow of cooling liquid. This can result from any of several causes (e.g. loss of fluid, damaged pump impeller, slow pump speed, contaminant blockage, etc.), NONE of which can be repaired simply. Replacement of the AIO system is your best choice.

Not the best of news but at least I have a clear course of action now. Thanks.

Consider a air cooler as a replacement worst that can happen is you replace a fan.

You really only need a AIO on a high end cpu and you are overclocking it. If you search the reviews on air coolers you will find that the modern air coolers are as good as AIO unless you buy really big AIO like 360
