[SOLVED] Downright evil CPU temperatures in new build; stock cooler on whirring overdrive

Hello guys

This is my build which I put together just last week: Ryzen 5 5600G, Gigabyte A520M DS3H, 2x8gb 3200 mhz RAM with heatsink, Antec 550W PSU, all in an ordinary tower. Win11 Pro x64.

Ever since I built it, the CPU fan has barely seen any rest. It's in constant whirring. I installed Gigabyte app centre information suite along with Core Temp to get to its rooot and the CPU temps reading (in both) were outrageous: 68-77 degrees C while idling, 80-85C if I opened any folder or the web browser. And the noise is terrible. How is this even possible. I mean, it's not demanding even for run down machines, much less for a build like this. I know something is wrong. The lowest temp I've seen is just 48C. Sometimes the temp is 80-82C in just idling.

The CPU is running with the stock cooler. It's got no thermal paste on. The guy who assembled it said on my enquiring that the stock cooler comes with thermal paste on and there's no need to apply it again.

I understand that this is not normal for any pc and I'm a little worried. I just want it to run normally.

At my end, I edited the System Fan 5 PWM-Temp curve in BIOS after watching a few youtube videos but to no avail.

I need help to fix this issue.

Thanks in advance.


PS: I don't game or edit stuff. I live in a tropical country but the day time temps where I live are stay at around 30-35C.

then change the thermal paste
That's it? Nothing else needed? Means, it doesn't come with thermal paste on, right?

Just forgot to add to the post, during the few days after the build and before I got a good UPS there were numerous power outages in my area causing it to shut off right away. Could that have caused this problem? Don't judge me please, I'm new to all this.

No that wouldn't cause your problem. First things that come to mind are:
  1. Cooler installation - Such as poor thermal paste application or not mounted correctly.
  2. Poor airflow within the PC - You say you have an ordinary tower, can you describe the fan setup, such as intake/exhaust and mounting position.
  3. CPU cooler is simply inadequate for the task at hand - I could understand under 100% load at 35C ambient, however you shouldn't get extreme temperatures under light loads.
  4. CPU voltage too high (unlikely).
Your ambient temperature is high but your temps still seem too high.

The CPU is running with the stock cooler. It's got no thermal paste on. The guy who assembled it said on my enquiring that the stock cooler comes with thermal paste on and there's no need to apply it again.
Yes it does but something clearly is wrong with this machine so it's worth a re-paste to rule it out. It may be the thermal paste is fine but the cooler simply hasn't been mounted correctly.

Why System Fan 5, where do you have the CPU fan plugged into?

A high idle temperature is indicative of a poor cooler installation.
When a stock cooler comes with pre-installed paste, the error is likely improper tightening of the cooler.
It needs to be done a bit at a time in a criss-cross fashion.
When you buy new paste, use alcohol to clean off the old paste.
Apply a small drop(methods vary)of paste on the cpu and reattach the cooler.
Do not use too much paste. It will spread out under heat and pressure.

What is the make/model of your case, and what is the fan arrangement?
Any cooler needs a good source of fresh air to do it's job.

I agree with posts above - best point to start is remove the old paste and clean off, re-apply good paste properly, and tighten down properly. FIND the instructions for exactly how much of that new paste to apply, and specifically for YOUR CPU chip, then follow them. Too little is bad, but too much also is bad, and there MAY be instructions on whether or not to spread it before mounting on the CPU chip top. Sequence of tightening the cooler down onto the CPU is important to get it straight on and just the right tightness.

Many CPU coolers DO arrive with thermal paste already applied. BUT in almost all such cases that film of paste is protected by a thin clear plastic film over it, and the installer MUST remove that protective plastic. Sometimes that is NOT done and that certainly CAN cause overheating.

Case if off brand, local made. It's otherwise fine I feel.

Stock cooler is plugged into the mb. I should start with paste reapplication.

The guy who assembled it
Ask him if he changed any settings in the bios, he might have pushed an overclock to make it run faster which makes your cooling run crazy.
Core temp also tells you the clock the CPU runs at so maybe you can figure it out by yourself, if it always runs at maximum clocks even when not doing anything you will have to change some bios settings.

Following the advice, I'm in the process of reapplying thermal grease and so have disassembled it. During the assembling I asked the guy to flash my bios to the latest version which he did, and I later I've seen my cpu run at top speed, 3.89ghz and 3.91 thereabouts, in my bios. I have not tweaked any of the settings myself.

Once I'm done with the heat sink thing, I'll put it back on and run core temp to check the cpu speed. I'll update you then and follow your counsel. It should take a few days, as I've ordered stuff from online. Thank you.

Hi

Sped up the process and this is the result now. No let up, it looks like.

I see sudden hikes and dips in cpu utilization. It like goes to 55-60% in an instant and then drops down to 3-5%. And the cpu temp too rises to 80-82C instantly and stays there.

Rarely I see this, like immediately after startup: https://postimg.cc/6Tb66BLc

I would deeply appreciate your help.

even without the fan spinning. that idle temp is too high

Your CPU should be running at 3.9Ghz and max 4.4 on one or two cores, having all cores boost up to 4.7, even if this only happens sometimes, means that you have an overclock going and as long as the cpu is overclocked anything else you do will not fix the cooler running at max. (other than getting a much better cooler)

I didn't even put the chip on the mainboard, much less overclock a locked chip. How can I disable this?? Anything to do in the bios? Yes, the ultimate solution would be to get a solid after-market cooler, which I'm not opposed to, but before spending cash I should like to try things on my own.

Take pics of your bios settings and show them here so that people can tell you what to change.
Or start with resetting them to default and see if that makes it any better.
