Question High temperature with Thermalright Peerless Assassin 120 Black

[Nikelat]

Hello,

I bought Thermalright Peerless Assassin 120 Black tower type cooling for my Ryzen 5 3600x processor, but my processor easily sees 80 degrees in any stress test.

I am sure that I applied the paste correctly, I removed the gelatin on the metal block, the fans are facing in the right direction, I tightened the screws well, I think there should be no contact between the processor surface and the metal block, and I can't think of any other problems other than these.

My case is MSI Vampiric 010m and there are 3 Arctic F12 fans at the front and 2 p12 fans at the top. What do you think could be the source of my problem?

If 80 Deg C is the max you see, you're fine. Is the dust filter up top on the case during those temps? Remove the front panel and see if that helps improve your temps, if it does then the case you have is the primary issue with a lack of venting in the front fascia of the case.

While I wouldn't call 80°C dangerous, it is on the hot side.
(what exactly is acceptable differs from person to person, some are fine running their CPU in the low 80s, others panic when they hit the mid 60s, some people prefer a cold system, others prefer a quiet system)
So some basic things

• have you pulled off any foil that might be covering the cooler? (at the bottom where it goes on the CPU. Forgetting that can happen to everyone)
• properly applied thermal paste? (It's just there to bridge tiny gaps on the surfaces, but if you use "too much", it will just be squeezed out.)
• how is the fan curve set up? Does the fan properly ramp up when you stress it?
• Do the temps improve if you set the fan to fixed max speed? (if not, there might not be proper contact to the CPU and the heat simply never reaches the cooler)
• it comes with two fans, are both running properly?
• you said you tightened the screws well, but it might be too tight and things bend. Try loosening them a tiny bit and see if things improve.

You said it hits 80 during stress test. What kind of stress test? Synthetic tests that hit the CPU full power like OCCT or prime95? Or CPU heavy benchmarks?

Hello, I thank you for your help and start my message by answering a few questions asked.

1- Yes, I removed the gelatin from my cooler.

2- I removed the front panel of my case and the glass on the side and ran the Power test via OCCT for 1 minute and during this time my processor hovered around 84 degrees. I would like to post an image, but I have no idea where to upload the image.

3- Yes, 2 of the fans are working properly and their directions are correct.

4- I think I applied the thermal paste properly, when I first applied it, I saw 81-82 degrees and I applied it again, thinking that it was less because of this, and when the result was the same again, I tried to apply the 3rd one and when the paste that came with the cooler ran out halfway through the application process, I added some of the mx4 paste I had and tried it and the result was the same again.

5- I think I have assembled the metal block properly, but when I tighten the 2 screws at the top and bottom to fix the block, I cannot reach the end completely, after a certain tightening, I don't know if it is due to the spring structure of the screws, but there is a squeaking sound and I stop turning it more because I feel like it is spinning for nothing. Should I tighten it to the point where tightening is almost impossible?

6- As for the fan speeds, I think they should be set to run at 100% at this degree, I will check this.

I can answer this way for now.

Unfortunately, my English is not good, so I am using Deepl as an intermediary, so I apologise for the communication problems.

 

[Nikelat]

Sorry I almost forgot to write this, during the OCCT test my processor was drawing 100-105w power and the voltage was hovering around 1.2-1.3.

Air choked. All coolers need air to function.
Highly restrictive front panel of the Vampiric 010.
[+]
Using fans not suited for high(er) flow restricted areas. The F12s are more suited for exhausts/heatsinks, and the P12s for intakes/radiators.
[+]
Fans in the roof of a case are to the benefit of most gpu coolers; gets the gpu waste heat out faster, but at the cost of warmer cpu thermals. For tower air coolers, these fans can be a disruption, like drawing air up and out of the case before the fans on the heatsink can grab it and move it through said heatsink.
Well, it's not a total disaster, as there's still preheated gpu air to use...

I have already answered most of the things you mentioned in the items above, I opened and tested almost every part of the case and the results were the same.

Anyway, while browsing the bios settings ‘’ When I saw that ‘Core Performance Boost’ and ‘Procession Boost OverDrive’ settings were on automatic, I turned them off and tested them again and I think I got interesting results. My processor did not go above 60 degrees in OCCT's 1-minute Power test. In 1 minute, the power usage was between 60-65w and the voltage was between 1-1.05.

I'm asking out of curiosity because I'm not knowledgeable in such matters, but can 40w energy and 0.2 voltage really cause a temperature rise that will make me 20 degrees difference? Please enlighten me on a subject that I am very surprised.

 

[Nikelat]

Additionally, I want to ask about this: I'm not sure how accurate it is, but I've seen people on various forums reaching temperatures of 80-85 degrees with these settings and a stock cooler. It seems strange to me that I'm seeing similar temperatures with a cooler like mine. Shouldn't I be seeing lower temperatures at least?

I have not used your particular cpu but it only takes very small increases in watts and voltage to greatly increase the temperature. When you play around with the overclock option on intel K series cpu you see huge increases in tempature for very small increases in the power limits. That is why a lot of people water cool the 13900k cpu when they mess with the power limits.

Most amd cpu say you can run them at 95c with no issues. You are not even close so it is not likely worth worrying about. I would change whatever you turned off back to auto and use get the extra performance. I guess you could do something like cinnebench 23 and compare the scores you get with the option on and off to see how much difference.

It depends on your use case but only a very small number of applications run all cores at max. That is why they test with cinnebench it is pretty much worst case so if you have no issue with that other application will be far less.

I will bet your temps during more normal usage are much less.

You have to be careful about comparing tempatures with other people. Most commerial reviews etc do not report the raw number they report the amount it is over ambiant. After being on these forums for a while I discovered there where people who run computers with no ac in the house when it is almost 40c air temp. Don't know how you sit and use a computer but in poor countries it seems a lot of people do.

If you were to crank the ac down in your house you likely would get better numbers.

In the end AMD says your temp is fine.
