Hey there, I bought a 7900XT reference card from CEX in the UK. It's used but comes with a two-year warranty from them. I've seen a lot of discussions online about AMD and junction temperatures—some people say repasting improves performance. The card has no visible warranty stickers on the screws or anywhere obvious, so you shouldn't worry about that. I'm using an ASUS AP201 case with plenty of fans and good airflow. After running Cyberpunk for about two hours with RT Ultra at 1440p and XESS on ultra quality, I get around 65-75 FPS, which is my preferred balance between quality and frame rate. The card is undervolted but has a higher power limit and memory clock; it's stable overall. The main concern is the junction temperature, though. It's worth mentioning I play with a headset and can't hear anything, so the fan speed seems fine.
The highest safe operating temperature for RX 7000 series cards is 110°C, meaning you're still 17°C short. As long as the card isn't throttling its performance, which shouldn't happen if it's truly at the max, a repaste probably isn't needed. If it gives you peace of mind, that's okay—but keep in mind there are small risks, like damaging the thermal pad or mounting issues that might raise temperatures further and require another fix. In short, I'm saying go ahead only if absolutely necessary.
Hey team, this was definitely the worst situation we faced because it got overclocked and boosted too high. I’m going to stick with what Blades suggested and let it run as is for now. I’ll only reconsider a repaste once my bank account recovers from the £2000 loss this week. Also, running the card at its standard 308W limit seems safe—just about 84kHz at the junction and only a 120MHz drop on the core clock. Thanks to AITech and YoungBlade for your support.
I might be a bit delayed but I tend to go off on tangents today. Unless you're extremely power-hungry, try keeping the power limit under 100%. You can reduce it to 85%-95% without noticeably hurting performance. Reducing voltage is a smart move since as long as the card runs smoothly, you significantly lower power use without sacrificing speed. If temperatures get too high, adjust fan settings to spin faster. The trade-off is more noise—it's up to you to balance comfort and efficiency.
In the end I followed these steps: I reset the power limit back to zero and adjusted the undervolt settings, which improved clock speeds in games. The 360W setting is available if needed, but I prefer 62C for the GPU and 84C for the hotspot, which matches my current configuration.
I'm back again, guys. Even though I mentioned I was going to leave as is, I ended up opting for the repaste and saw some great improvements. The hotspot temperature dropped by 10°C while lowering the fan speed by 100rpm—exactly what I was aiming for. I did notice some bare die near the center in the OEM paste, possibly due to pump-out or poor application. I used Thermalright TFX because many said it’s thick and resistant to pump-out effects. I’ll keep an eye on its performance over the coming weeks and months, but the early results have been really promising.
