I’ve got an Inno3D RTX3070Ti and I’m wondering if I should be ok using some liquid metal thermal compound on the gpu die? Here’s a pic showing the original thermal compound from the factory. I got some liquid metal thermal paste from AliExpress and wanting to give it a try and see if it’s actually any good. Speaking of the liquid metal paste I got, had anyone heard of or used something called Upsiren LMTG100? Is it actually any good?
I know liquid metal compounds should never be used with aluminium heat sinks and just wanted to confirm if my gpu is ok to use the liquid metal? I’m pretty sure my hsf is made from nickel plated copper as it feels way too heavy to be made from aluminium but just wanted to confirm this before I go and ruin my gpu cooler. Any advice would be greatly appreciated.

I have no idea about it “being ok to use” on this gpu but i dont think you need it. Are you going to overclock it by a big amount?
Use ptm7950
Just use PTM and stay clear of liquid metal if you’re not into heavy overclocking, which I assume you aren’t based on the fact that you own an Inno3D 3070ti.
PTM is a way better solution for long term use and not even remotely as easy to get wrong.
I doubt anything will be damaged by the liquid metal alone (disregarding spillage/user error)
Have you squeezed any out of the tube yet? Looks like the side of the box calls it “liquid metal silicone grease,” so idk if that’s some Google Translate error or what
use ptm7950
I used PTM 7950 on my RX 6800 XT and I’m getting 56C core/60C hotspot with 220W and fans barely touching 50%. PTM is much safer and if even if I go like 312w on my card it is staying 65C At core, 80 hotspot with fans at the same 60%. Undervolting is the key. Before the PTM I was getting 90C hotspot.
Given all the fancy gaskets around factory liquid metal to stop it going where it’s not supposed to – remember it’s both conductive and highly corrosive to solder – I’d say it’s a less than great idea for long term use.
PTM7950 is what you want. Extremely good performance, truly exceptional longevity & long term stability. Won’t dry out, won’t pump out, won’t go sparky walkies like LM.
I would highly recommend using PTM7950 or Thermalgrizzly Phase change sheet.
I applied it on my laptop 7945HX and 4080mobile.
Temps before repasting: (Same fan curve/cooler setting)
1. Cinbench performance mode: 103C (Thermal throttling)
2. Cinebench performance mode per core CO: 101C (Thermal throttling)
Temps after repasting: (Same fan curve/cooler setting)
1. Cinebench performance mode per core CO: 86C
2. Cinebench performance mode, PBO 10x, +200MHz OC and per core CO: 92C
