Thanks!
So far, both my RX580 and 1080Ti are both undervolted, and never need to work above 75C.
This liquid metal mod is quite unnecessary for me at this moment. But I may still perform the mod. Then OC the card and see how far I can push them.
Or further reduce fan noise is also a good idea.
Just take my time to apply liquid metal to RX580 and W3690. Success!
And now, with undervolt, even running Furmark, my RX580 won't go over 75C, and don't even need full fan. And I need 10min Furmark to make it achieve 75C temperature. The cooling is definitely more effective than before.
On the cMP, the effect is again very noticeable. The CPU now can hardly go over 76C with roughly idle fan (system ambient 33C). With AS5, it usually stabilised at 78C with fans spin up to around 1350RPM (my own fan profile). And that figure was with 30C system ambient.
Even I don't really need it, but quite happy now. Let the liquid metal do its job is better than let it sitting in my tool box.
The next one will be my Hackintosh's 1080Ti, but I really need some time to study how to open the PNY XLR8 1080Ti properly. It doesn't like normal card. e.g. It seems the backplate cannot be removed. An interesting card.
------------------------------------------
Update 1: 1080Ti also done. Crazy effective now. Can run Superposition @2000MHz and the GPU can just touch 71C. Again, that's 15C cooler straight away.
Anyway, learnt something. Those colourless nail polish works.
When I apply liquid metal. I usually apply it to the surface, then turn it upside down, and use the
syringe to suck out all excess liquid metal (the liquid metal will looks like stalactite if too much. So easy to determine).
However, this time, due to the fan connector is so tight. I don't want to pull it too hard just in case break it. So, the cooler was attached to the card all the way when I mod it. Therefore, it's not that easy to turn the card upside down. So, I skip that part, and just apply liquid metal like normal thermal paste application. Apply it, looks good, then put the heatsink back on.
But this time I am over confidence. The PNY cooler is really well manufactured. The gap between GPU and heatsink is really tiny. Even the liquid metal looks thin enough to me. Actually, still has little bit leak at the corner position (when I put the heatsink back on).
Therefore, some of liquid metal "touched" those resistors that right next to the GPU die.
I didn't know about it. Just re-assembly the Hackintosh and fire it up......no image. Change the output to use iGPU via motherboard HDMI, the Hackintosh still working, but the computer can't see the 1080Ti. Oh~ I may damaged it.
So, open it up again, and I see the leakage now. Then I use forceps and some tissue to remove the leakage, and try to put the heatsink back on a few times. Make sure nothing will spilt out and able to touch those resistor again.
Once finish, re-assembly the card (and the Hackintosh). The 1080Ti back to alive!
So, those nail polish works, nothing really breaks. And I am a happy Hackintosh user again
