Question Is it my CPU cooler that’s faulty or something else

Issues with high CPU temps and I want clarity that the issue is what I think it is.

Had this gaming PC for 4-5 years with next to no issues. Yesterday had my internet dropping out on my PC and only my PC despite the internet still being functional and online just not on my PC. The following day the computer shuts itself off randomly.

A red light appears on my motherboard during startup, not entirely confident in my knowledge on this or rather what specifically it’s trying to warn me of outside of ‘issue with one of your components’.
So I load it up again and check a few programmes i have to monitor things in the PC such as core temp etc.
My CPU on start up, starts at around 70-80 Degrees Celsius and will gradually climb to 95 and will try its best to remain there but will continue to climb to 100+ before i eventually shut it off myself but during this the core speed drops to 0.55Ghz when it’s base speed is 4.70Ghz so i’m pretty confident in saying it’s thermal throttling.
So i reapply thermal paste and it made no difference so my next thought is the cooler. The fans are still operating and the radiator is practically spotless with no visible clogging. So my last thought is the pump but i’m financially strained at the minute and there’s too many issues with the PC for me to bank it all on one thing that i’m 70/80% sure is the cause of the problems. I have no reliable way to test the pump and I don’t want to run my PC incase the temps damage the CPU or whatever else.

So based on the information I provided and i’ll try to provide more if possible, would the pump on my CPU cooler seem like the issue ?

I wanna clarify that I know thermal throttling slows down the processor but is it normal for the temperatures to start off so high especially when the computer hasn’t been turned on in a few hours? Would thermal throttling turn off network adapters and GPU to prevent overheating?

What BIOS version are you currently on?

Take the side panels off your case and pass on what you're seeing as the stickered sides of the PSU. How old is this unit?

Page 0, they don't specify what the LED indicates but since you're in front of the system, you can either read off of it and tell us what it corresponds to or you can pass off an image of the LED area and we can corroborate your assumption.

That sounds like your AIO's not doing it's job or the mounting on the CPU isn't proper.

Had this gaming PC for 4-5 years with next to no issues.
The processor you own was released in Q3, 2022...can you clarify what parts were recycled from your older build?

Please include the make and model of your case.

Sorry for the delay! Currently looking at new replacement parts.

Apologises for the delay, having trouble finding an appropriate cooler replacement in stock.
Bios Version - Gigabyte F2
PSU - CoolerMaster 1250W MWE GOLD V2 - ATX 3.0 PSU
Case - (Having trouble finding the specific model) It’s from cooler master and the closest I can find is -Elite 302

As for recycled parts, I might have been mistaken on how long i’ve had this PC since I haven’t replaced anything in this PC yet so to adjust, I’ve had this PC roughly 2-3 years then(bit of shock from this felt longer lol).


As for the red lights, it starts off with the light on the left being displayed then switches to the one on the right shortly after. I’m currently on my phone and I’m not sure if this website is compatible with phones and as such Im having difficulties uploading the photos.
 
AIO coolers do not last forever.
In time, the mechanical pump fails or gets clogged. Or air intrudes through the tubes requiring replacement.
Think 5 years.

I suspect the cooler is the issue.

Fortunately, your case looks like it has good airflow and a simple twin tower air cooler replacement will do the job.
Thermalright peerless assassin is about $50:

The cooling capability is about the same as the H100.

I did some digging and according to the manual(it doesn’t label them specifically as to what light corresponds to what but assuming they follow theno

Yea I think that is the issue too just abit perplexed by the motherboard red lights.
Thank you for the recommendation I was just looking at that one aswell!
 
My phone is not having a fun time with this site but as i was trying to say. The LEDs that are displaying on the motherboard I BELIEVE (don’t quote me because the manual doesn’t do the best job explaining) corresponds to CPU issues and then switches to DRAM LED shortly after the CPU LED goes out. Sorry for the mess of replies.

Picture you can upload to Imgur View: https://imgur.com/upload

Can you monitor pump rpm ? I suspect it may not be turning or too slow.

First time using Imgur so hopefully that works. I’m a little hesitant to turn on my pc at all, the weather is pretty warm and the CPU overheats to 95+ in maybe 2-3 minutes but from when i was checking BIOS from the other day 2 of the fans weren’t being picked up but were still running and i’m not entirely sure if that was the pump or not, currently going to research it a little so i can try get the information as quickly as possible for when I do boot it up since i won’t have much time.
 
Checked the BIOS and the only fans that are being displayed that are linked to the CPU are:
CPU_Fan - which is operating properly and I assume that’s the fans for the radiator on the cooler
CPU-OPT - which isn’t functioning at all or atleast isn’t showing up in BIOS
