You're planning to purchase a 7800X3D during Black Friday and combine it with liquid metal. You're considering using a conformal coating to protect the side of AM5 processors if the liquid metal might leak. The tape you found at the hardware store claims to handle temperatures up to 275°F or 135°C, which seems suitable for modern processors. At just $10, it's more affordable than premium shipping options on Amazon. If this solution doesn't fit your needs, you may want to explore alternatives such as higher-temperature encapsulants or additional thermal management components.
Avoid using liquid metal on the 7800x3D. It offers no advantage and doesn’t provide any real benefit. Ryzen CPUs handle thermal management well, so LM isn't necessary unless you're connecting directly between the die and the heatsink. For better performance, stick to a solid paste and a reliable cooler. AM5’s thicker IHS caused some problems before, but that mainly affected higher-power models like the 7950x and 7900x. The 7800x3D and 7700x didn’t gain much from delidding since they ran at lower power. This setup usually works for similar applications, though I still advise against it for your CPU.
If it helps keep mobos from getting wet, it should also help protect the CPU from liquid metal. Just make sure your motherboard supports ECL technologies like the B650e Taichi (lite), AORUS Master, X670E-A/F, etc. Avoid this approach if you don’t want to overclock. For better temperature control, consider lowering the system’s temperature by removing parts—this is the most effective method unless you’re ignoring advanced cooling options. The 7800X3D runs quietly and efficiently, making it simple to maintain temperatures well below freezing. Proper insulation matters, and building a dedicated CPU block can help connect to an AC unit for optimal cooling.
??? There is 100% a gain in thermal performance using liquid metal on an IHS and cooler. The risks are there yes, but they are manageable, and thats why OP is aksing.
You're thinking about pairing an ASRock X670E PG Lightning with an AM5 CPU. It seems to offer overclocking potential, though it's hard to compare specific models clearly. The board was notably affordable and many issues were fixed via BIOS updates recently. I'm weighing the option of swapping the CPU for a direct die, but thermal solutions are currently unavailable in the US. My setup will use two 360mm rads in a water loop (7800X3D + 7900xtx), so I feel the extra warranty cost isn't justified. Liquid metal appears to be a more budget-friendly and less complicated choice for heat management. I'm open to swapping later, but availability this time wasn't an issue.
Opt for the B650 Taichi Lite instead of the X670e PG Lightning. It offers significantly more I/O and features like postcode, ECLK for X3D OC, which the X670E lacks. The garbage IHS and insulating cache layer could make Waterloop nearly ineffective—heat from CPU cores won’t reach the cooler properly, and GPU air coolers usually handle temperatures well without extra cooling solutions. Trying to overclock X3D will need serious precautions, like a cold phase-change loop or a dedicated AC unit. It’s safer to stick with AIO cooling and skip Waterloop, especially since temperature differences won’t help the GPU performance.
