News Noctua's Offset Mounting Bars Can Lower AM5 CPU Temps

[Kamen Rider Blade]

Busier weekend than I thought and didn't have time... planning on tackling this after work today.

Cool, no worries. Do what is necessary.

I'm not sure who "all the people" are that are bitching about AMD's CPUs running hot as they are totally reasonable temps for modern performance oriented CPUs

Since you're going to have to re-mount anyways, you might also want to try the new hotness in Thermal Paste.

I needed to undervolt my 12900K to get it down to 89C with a D15

You're also using an X3D version, which is has a lower default operating voltage, a lower TDP profile, and a lower Tj Max spec.

And that reminds me that another thing about overclocking makes a difference: what paste do you use? I use Thermal Grizzly Kryonaut which is among the top performers. For reference it performs about 3C cooler than the popular Arctic Silver 5. I applied it to my RTX 3080 Ti as well.

Ok... results are in. Before I post all the info let me just say that I am pretty sure I can disassemble/reassemble this PC blindfolded now with all teardowns I've done with the initial 7000 series meltdown back in mid-April to now testing the new offset bracket.

That being said... here we go. @Why_Me make sure you take a look too. Cool stuff.

Starting at the top... the original brackets and paste as seen on the chip/cooler on initial disassembly. Top right is the new offset brackets.

Bottom is the pea sized method I use... with the obvious difference seen on cooler due to the offset... and the spread on the chip.

This was running an all core burn test and as you can see the offset bracket made a difference... I am very impressed with the 3C difference the bracket gives. Very impressed.

The Corsair paste didn't do much... it was at best equal but certainly not better than the MX4.

What's sad is after running the last tests with the Corsair paste and seeing the temps slightly higher I just couldn't leave it like that... even if it was only 1C. So I tore it down AGAIN and went back to the MX4 paste.

I ran another test after and the MX4 remains a solid 1C cooler than the Corsair paste. Not a huge deal in the grand scheme of things but I still went back to the MX4. At any rate this was fun... and as you can see the offset bracket definitely made a difference.

Thanks Noctua.

Dude that is AWESOME!!!!! I'm sure you helped some others out there as well. Great work - now grab a beer!

Try using the "Buttered Toast" method for Thermal Interface Application, the Pea method isn't that great compared to the "Buttered Toast" method.

It's been tested to give you the best results by spreading a very thin even layer between above the Heat Spreader.

Thermal Paste Application Techniques

The best technique to apply thermal paste is something that is often debated, and as a whole the internet has not decided on a standard technique. There are many varying techniques that are recommended, so in this article we will best test a variety of techniques to see which performs the best.

Thanks! It was fun and hopefully helped someone out. These offset brackets are definitely worth the $5 I paid!

Ok. I've always used the pea method but not against giving this a try. Will have a look.

Thanks!

I prefer the "Buttered Toast" method, a nice thin even layer where you can't see the Heat Spreader will gurantee that you don't have any air bubbles for Hot Spots to occur.

Just give it a try, take your time, I usually take my time as well.
