Temps go high with air cooling

[msacco]

Hey, I'm using the Peerless Assassin 120 SE with my 5800x, been using it for a year now and lately I'm starting to notice some heating issues, when CPU is running at 100% temps reach a maximum of 90.5C(not staying there, that's just the peaks).

While some comments I've seen online indicates that it's not a big deal, first of all I'd prefer not reaching these temps, and second my cooler used to work much better.

When I first installed it the CPU was running on around 40C on idle and around 75-80C when CPU is running on 100%. Now it's running at around 50C on idle and 85-90C at 100%.

According to benchmarks, it seems like that cooler should be able to handle the 5800x decently.
 

I wonder what I should try, is it just reapplying thermal paste? Should I replace the fans to better fans maybe? I don't really care about noise, maybe I can slightly boost the fans RPM somehow to make it work slightly better.

I'm not familiar with air cooling degradation since there shouldn't really be any, any suggestions?

 

Thanks.

@msacco You are measuring with the same room temperature?  Checked for any dust buildup?

I bought the cooler exactly a year ago, so temps should be around the same, my AC is always on too, temps are probably not exactly the same but 10C difference is surely not the case. I did try to check for dust, cleaned a bit but there wasn't much to begin with.

Then I think you are right, next step would be to re-paste and see if it makes a difference.

I expected the thermal paste to last longer tho. I used the thermal paste that I received with the cooler, should I maybe try some higher quality? I don't want re-paste every year. I use the X method btw, I found it to be pretty decent.

Thanks.

The TIM that came with your cooler is actually pretty awesome. It was the way you spread it that is the problem. I have that cooler, and can say for a fact that my X3D never comes close to your temps.

The one thing I'm certain about is that the spread with the X method consistently works fantastic for years now, so it's surely not that.

Everyone has their preferred method for pasting. On AM4 I am a spreader. I find it works best for me.

 

I am arrogant for reasons you do not need to know for now. Though I try to be humble about it.

 

Edit:

 

Just the fact you said you get a good spread with the X tells me you are using too much.

a few years back i had a similar case, for me replacing the fans with higher quality fans(noctua) solved it but i cant tell if its the same issue or not

OP didnt mention their case though? Also, fan performance have normalized by a lot, the custom C12 on Peerless Assassin is a neck better than Arctic P12 and Noctua F line.
