CPU overheats idle in BIOS

Hi,

I have bought a desktop PC with the below spec from PC Specialist 12 years ago. I'm happy with the PC so far and it still works very well for my use cases, until recently. Last week Windows started with some emergency shutdowns due to CPU overheating. I installed a tool (Core Temp) to monitor the temperature and noted the temperature creeping to around 90 degrees Celsius (even without any applications running in Windows), at which point I have shut it down.

This has now gotten worse and the CPU overheats now even without launching Windows. Even when running fully idle in BIOS the CPU will overheat within around 30 seconds. I'm attaching a few pictures from my BIOS and from the cooling unit.

What I have tried so far is cleaning the inside of the case (which was very dusty) and tightening the screws of the cooling unit. I believe I have also deactivated all the overclock settings, these were never activated over the years. Neither helped.

Would you have any suggestions on how I could track down the cause of this overheating issue and debug it? Thanks!

Id say after 12 years that aio has failed and is no longer capable of cooling the CPU. So first step would be to replace it with even an air cooler and then evaluate if it’s worth keeping build going, or start thinking about a replacement

Thanks B4zookaw. I'd definitely prefer replacing the cooler rather than replacing the entire build.

The issues are that ...
- COOLIT ECO A.L.C (ADVANCED LIQUID COOLER) doesn't seem to be available for sale anymore. Couldn't find it anywhere on the web.
- I don't have any experience fitting any liquid coolers or even fans but I'm happy to give it a try.

Is it possible to say whether I need a replacement liquid cooler or if a regular air cooler would also do the job here? I'm not planning on overclocking the CPU.

I'd be looking for a cooling solution which is as simple as possible to install while still being compatible with my old CPU socket size and the size of my existing radiator (if relevant). Would you have any recommendations of compatible products?

Here is a video of my existing cooler: https://www.youtube.com/watch?v=IPJxg8m5PsA

Thanks again.

Yeah, you won't find that AIO available anymore, a very old product. I wouldn't look to replace a 120mm AIO with another AIO, you'd get as good if not better performance with a good air cooler. The Deepcool one that Scott linked to would be good, you can get it in an all black version as well if that is a preference. https://uk.deepcool.com/products/Co...formance-CPU-Cooler-1700-AM5/2022/16166.shtml Or if you want Noctua goodness: https://noctua.at/en/nh-u9s-chromax-black

Fitting an air cooler is not too hard, if you can use a screwdriver, you're half way there. The instructions that come with any cooler will be easy enough to follow.

Thanks Scott and B4zookaw!

I have now removed the AIO and measured up my case. While I like the budget price of the DeepCool AG400, with 15 cm it is too high and I wouldn't be able to close the side door of my case anymore. With a height of 12.5 cm the Noctua cooler for £68 would fit. I will probably go with that one unless I can find another decent cooler in a similar size closer to £30.

You won't go wrong with the Noctual, but they are pricey. I would probably just shop around and get any old 1155 that fits :)

Limit yourself to a minimum of £20 and I would say you won't go wrong.

The cooler is now installed. Installation was easy (except that I had to remove the entire mainboard from the case to insert the backplate, but that's the case's fault, not the cooler's).

The cooler works well. Have stress tested the CPU with 100% load on all cores for 10 mins and the max temp did not exceed 61 degrees C. Not bad.

Thanks again everyone!
