Question Do AM5 chips run hot or what ?

[krzyimprt]

Am I crazy to think my CPU hit 95c? idling 37c, gaming 40-65c, rendering 70-80c. prime95 96c.
Peerless assassin 120.

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.

Ambient room air temps would also help us two fold. Adding info about the number of fans in your case and their orientation would also help us two fold.

They are designed too boost power and temps to 95°C.

That case isn't helping with cooling at all, though.

It shouldn't hit 95c limit with that cooler if it had good flow. If you have any disks in top cage, move them down and replace with an intake fan, Air coolers are just as good as air flow in the case. Prime 95 is not meant to find temperature under load but to check for stability in case of other troubles. It's a troubleshooting tool. If your programs and games run stable up to 80c, no need to torture it to limits it would never reach normally.

The picture seems to show that the CPU cooler is spinning, but the rear fan is not. This will contribute to the cooling performance of the system.

What's wrong with my case?

 

[drivinfast247]

What's wrong with my case?

Does it have front intake fans?

 

[Eximo]

At quick glance, Cooler Master HAF 912 or similar?

I recognize the stock rear fan, drive racks, and the top fan hole design.

Should have a front intake fan buried in there, but if it is as old as I think it is, every case fan needs replaced anyway.

 

[Buffer0195]

every case fan needs replaced anyway.

I second doing this. Your CPU fans might be okay, but I would make sure that rear fan activates and add one as exhaust to the top of the case.

If that doesn't help ensure you have thermal paste applied, I use Arctic MX4.

As a last resort you may want to clock down your CPU multiplier. Follow a guide online and be comfortable resetting the motherboard settings if you do this.

 

[krzyimprt]

It has two 120mm intake fans. They probably have over 50,000 hours on em. Any suggestions? Preferably PWM. I thought about Noctua's but god are they expensive. Rear fan is spinning fine.

I like Thermaltake fans for how inexpensive they are compared to my personal experience with their failure rate. You can check here for some that I've used that are not LED fans.

That CPU should hit 95°c while running Prime95.

Yeah, but what's the need for Prime95 when nothing else loads system that much ? Unlikely ever will.

I'm just saying that's how these 7xxx are designed to operate.

 

[CountMike]

They are as well as 5xxx but doesn't mean it's good to operate at or close to temperature limits . over 80c and already some boost is lost.

Just cheap PWM fans:

[sonofjesse]

Peerless 120 is good and I have no issues on my AM5.

A better case design would not hurt for sure.

Look like the only time it hits 95C is when your doing PRIME 95.

I know people are obessed with PRIME95 for years.

But if you using your PC as normal and staying under 95 I don't think I would worry.

Most newer cases dump all the 5.25 bays and provide 2 or 3 fans to intake. Really helps a lot.

Didn't AMD themselves say it's fine to operate at those temps?

Again, it doesn't mean they should.

Why not?

 

[Eximo]

Why not?

Higher temperatures mean greater thermal expansion for one. Two, you have increased internal resistance, the higher the temperature the more power you have to push through, so less efficient the warmer it is. Three, chemical and electrochemical reactions work faster at higher temperatures. So anything going on inside the chip at the microscopic level is accelerated. That would be things like electromigration or crystallization effects.

You better set up a meeting with AMD engineers and let them know their mistakes.

They know all that, therefore limited 3 year warranty. Also a spot that is overheat indicator. Throttling when just couple of degrees hotter than maximum allowed temperature. Ryzen before 5000 series had over 30 degree margin.

Remember, engineering is about designing a product or solution to meet specifications. If those specifications call for a disposable product designed to last 7-10 years, that is what you get. If they were designing a chip to last 25-50 years they would do things very differently.
