Review: Amd 6000 series temperature cure - I have a 6600xt and like most 6000 series amd gpus mine ran pretty hot especially on the hot spot which is on the pcb and not the die on these cards. I had tried repasting and repadding twice and no change in temps. I used this putty on the pcb and tg duronaut on the die and my temps dropped 15c on average. As for working with it I recommend gloves as it leaves behind a residue but it was easy to use and did not make a mess.
Review: it is incredible how well it works, best product out there - it is incredible how well it works, best product out there, a year later after installing and the paste is not even close to dry

### ⭐⭐⭐⭐⭐ Difficult to Work with Yet Worthwile
*by C***T on December 17, 2024*

I got tired of getting worried about buying the right size thickness of replacement pads after buying two XFX RX 7900XTX Merc310 video cards I wanted to repaste with MX-6 on the GPU die. I never trust OEMs on using premium thermal paste or pads, and I was right. One card had too little paste, the other bubble areas from pump out. Forget using the spatula for anything other than just grabbing a bit of this stuff out of the bottle, go for full coverage rubber, nylon, whatever gloves. I learned it's best to start the flattening process yourself with a single finger. Use the spatula to cut off excess, but be ready for this stuff to come apart and get stuck to your gloves when you least expect it. Cleaning the surfaces with 91% or above isopropyl alcohol helped it to stick especially on the VRAM. **One major note. Expect to use 1 full bottle of the larger size of this stuff per graphics card (GPU). Each VRAM row in my card was 8GB, so 3 full rows of VRAM for the 24GB. Add in the capacitors, ICs, other originally covered with pads and I can guarantee you it's best to have a full large bottle versus 1 small bottle per card!!** it was worth it though. The VRAM temps alone from this stuff dropped about 8C without load and almost 10C under load. Was it perfect application..probably not but who cares.
