Question What is wrong with my CPU ?

[kubacs]

Yesterday I was playing a game and my computer randomly shut off, I turn it back on and I saw a CPU overheat warning. This kind of scared me and I started to question my aio if it has died (corsair h80i). I start monitoring my CPU temps and turns out, my idling is really weird, I often idle between 40-60 degrees, and spikes of 10 degrees happen quite often, a few times a minute. I have openhardwaremonitor and my max while idling spiked up to 71c.

This happened out of nowhere, and was completely fine for years before, only happened once before but that was when I tried to render a video without gpu acceleration. Anyways, I decided to swap out my AIO cooler thinking as it was dead with the original ryzen wraith cooler, and put new thermal paste on it, and the results have not changed. I still get very high temperatures while idling and gaming, and when gaming earlier today I saw a high spike of 96.3c, which is crazy.

So to date I have completely cleand my case & replaced thermal paste with old aio, no change, then changed cooler back to wraith and again replaced thermal paste, no change.

Is this normal? What could possibly be happening, this is completely out of nowhere.

Ive also attached openhardwaremonitor log which i ran for 30 mins if anyone wants to filter through that and check out my temperatures, this log is purely while idling and afk.

My specs are:

CPU: Ryzen 7 3700x
CPU cooler: corsair h80i (now wraith)
Motherboard: B550m mortar
Ram: 32GB ddr4 3600mhz
SSD/HDD: nvme m2 wd blue
GPU: rtx 3060
PSU: corsair tx750m
Chassis: zalman z11 plus
OS: w11
Monitor: benqxl2540k


Help would be appreciated, thanks.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

(corsair h80i)
Does the radiator dissipate heat or is the tube and the cooling block/pump block the only things that are hot to the touch?

I'd lay good odds that the pump failed in your AIO (they don't last forever)

to be honest didnt think it would matter as my chassis and gpu dont have anything to do with my cpu cooling.

anyways the fan was exhausting and i think it was.

Put back the wraith cooler and temps seem to be kind of improving? theyre still quite high though, often reaching 90 and above when gaming

On the contrary, yes your chassis can help with cooling. Good airflow is essential. What thermal paste did you use when you repasted? What method did you use to apply it?

The 3700x is a 65w CPU, so shouldn't be getting such high idle and gaming temps IMO. Those CPU's have decent efficiency. But, the wraith maybe the issue now. It's just not good at cooling.

10c spikes on Ryzen 3xxx/5xxx are normal, as all cores will boost, hence the spikes. Nothing to worry about there.

It can also be that way too much paste was used (any more than required to fill the microscopic scratches and pits acts as an insulator). Or, paste was reused when mounting a different cooler, thus introducing air (an insulator).

yeah suppose youre right there, anyways the case is a zalman z11 plus (yes still stuck in 2013), not sure how the airflow in this is really, probably not as good as something new. Ive got one intake at the front, cpu cooler and one exhaust at the back.

Thermal paste is arctic mx4, however it is slightly old ish? I got it around 3 or 4 years ago, looked fine and spread fine. I put a small rice grain size in the middle of the cpu for it to spread evenly.

Thing about the wraith is that it actually has better temps that my corsair h80i.... still high though.

I use a rice grain size on the centre of my cpu, should be perfect, been doing it like that for years without an issue. I also never reuse my paste, every time i take some cooler off I always make sure to properly clean with isopropyl alcohol, and then reapply new thermal paste.

 

[Roland Of Gilead]

Once you've opened a tube of paste, I'm pretty sure it has to be used within a certain time frame. The paste could be off.

It might be an idea to get a new tube, and try again. Arctic MX-4 s fine for your needs. Noctua Nt-H2 is also a very good one.

The rice size method although often advised, perhaps isn't the most reliable way. You could try the 5 dot method (just google) or layer the paste all over the chip, using a plastic tool to apply the paste thinly, and evenly across the whole chip.

Let us know how you get on.

grain size of rice doesnt really work for the ihs on amd chips its best to spread it due to bigger die size.

also 120 aio are not that great for ryzen 7 3700x.

also wraith is pushing it on a ryzen 7 3700x

your better with a thermalright burst cooler. or aio 240

 

[Roland Of Gilead]

A Peerless Assassin would be a good fit there. Cheap and powerful.

Temps seem to be improving, but I might play it safe here and order some new thermal paste, i am probably pushing it as i got the paste like 4 or 5 years ago.

Before I used the rice method when I took the cooler off it was spread fine, anyways, ill give the 5 dots a go.

Thanks for the advice

Worked fine really, the 120mm aio was also completely fine and never really went over 75 tbh, wraith seems to be working right now, lowering the temps from that crazy 95s down to 80-85ish. Not really in the market for a new aio atm, but ill have a look at the thermaltake. Thanks

Will take a look at that, thank you

Optimal temperature for all Ryzen earlier than 5000 series is up to 60-62c, over that boost is increasingly lost.
