Test and Experience with GPURisers 20 W/mK Thermal Pads on 6900XT

[Memmento Mori]

So again i had some fun with my 6900 XT and was curious if changing thermal pads will make a difference on my card (was just bored to be honest...) 

 

I found this thermal pads - GPURisers 20 W/mK Thermal Pads and found as well just some information's or reviews on them like: Kritical 20W/mK pads vs GPUriser 20W/mK pads 

 

 

 

Originally i wanted to buy the Kritical Pads, but they were sold out and the PGURISERS were on stock in UK so it was for me a clear decision...

 

As usual i made a temp testing before the change:

 

 

GPU Temp: 62 C

GPU Memory Junction: 64 C

GPU Hot Spot: 75 C

 

I forgot to get more pictures of the replacing at it self, as i was already to inpatient and wanted to see the results ASAP   For this reason i could not do any kind of reviews, I'm not patient enough lol...  Respect to all reviewers on this place  

 

 

Just to explain, i got the following information's from XFX about the pads thickness: 

Front:

VRM 1.5mm , 2mm

VRAM 1mm

 

Back

VRM 1.5 mm

GPU, VRAM 3mm

 

I as well repasted the GPU about 6-8 months ago with LM and as you can see there is no corrosion on the cooler at all which means its copper   Anyway here are the results after the exchange of the pads:

 

 

GPU Temp: 59 C

GPU Memory Junction: 72 C

GPU Hot Spot: 71 C

 

Compared after the test the results and noticed that the GPU Memory Junction temp increased by 8 degrees while all other temps were down by around 4 degrees on the GPU Hot Spot and  2 degrees on the rest. So i just took it appart and could see that on the Memory modules are no imprints on the Pads. So i just replaced the original 1mm thickness by 1,5mm pads and tested it again.

 

 

GPU Temp: 60 C

GPU Memory Junction: 62 C

GPU Hot Spot: 72 C

 

This time the temps looked OK and the final result is basically 2 - 2,4 degrees on the Memory and VRM... The decrease on the GPU hot spot could be a result of dipping a bit more LM on the cooler and I guess it has now a better contact with the chip...

 

So im happy with the result in the end, now i just hope they will not degrade that fast   but time will show. 

 

Any experience on your side ppl? in general what is a good result in Degrees for changing pads on the GPU? 

 

Thanks for any input

I haven't tried replacing pads on my card (yet).  What's interesting is the delta between core and hotspot temps.  You have about a 12*C delta.  I have over a 50*C delta on mine.  MSI says its fine.

I dunno man, your temperatures seem to be fantastic on your card.

This is interesting stuff - I might give it that W/mK 20 a try in future builds ! 

FYI, I use a custom 3x8 PCI power 6900XT primarily on a 24/7/365 work machine, but I still 'tuned it' just the same with MPT bios tools, 10 W/mK thermal putty on the VRAM (+ Gelid GC Extreme paste on the front and back of the die) and a Bykski water-block back in the spring of 2021...still running strong and showing exactly the same temps now at a given ambient.

 

Stock 'air-cooled' on day one vs water-cooled with thermal putty w/ custom MPT, noting also the different core voltage and PL loads:

I did new pads on my 6900XT, but it also got a full cover HeatKiller block at the same time.  The pads I used were the same pads I've been using for a very long time on all my cards, which are the Fujipoly ultra extreme.  I am just always on the look out for deals, since they are expensive pads.

 

The only card where I saw some major temp drops was with a bunch of highly OC'd 7970's.  The workload they were running was basically FurMark on the VRMs. I was able to lower VRM temps by more than 20°C after swapping in the higher quality pads.
