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


Recommended Posts

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:

 

afterrepading1hDyingLight.thumb.PNG.7de7b05b07c9f78d4c57636e78afb839.PNG

 

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.

 

afterrepading1hDyingLight2.thumb.PNG.fe54dc9cde2217bc2ff3d9d6eadf9bcd.PNG

 

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.
