Processor Weird signs appear as unusual markings on the device.
I was cleaning my computer recently. While doing so, I removed the CPU fan of the Ryzen 5 3500x to replace its thermal paste. I also took out the processor from the side near that golden arrow and noticed some black and greenish spots. It doesn’t seem like a burn mark, and the CPU is running normally. My other Corsair CV-550 PSU stopped working without any sparks, noise, or odor. What could have happened? I need some advice.
Uncertain about the risks, but it seems to resemble a burn mark. Searching online shows similar images. It might indicate a faulty CPU or memory. The PSU could also be the issue, though I can't confirm. I can't guarantee the CPU will function properly. My best advice is to upgrade to a higher-quality PSU if possible.
If it functions properly, it seems unlikely you need to be concerned—attempting to clean it if there are no burn marks might pose more risk than benefit, since damaging a pin could disrupt communication between the CPU and RAM. There’s no visible evidence of burns or damage in the socket area that matches this spot. If everything appears intact, it’s best to leave it as is and let the CPU restart; if issues arise later, you can address them without undue worry.
I still switch to a more modern and higher-quality PSU, ensuring it isn’t a sign of an issue. It’s not about power output or voltage levels, but if problems do occur, a better PSU will handle surges, shorts, and other issues faster. This helps avoid total damage or reduce the impact during such events. Since the CPU appears burnt, it seems the SOC pins—known for high power and voltage—show signs of damage.
Green indicates oxidation, which is unusual for the pins. What's its age? Are there any related damages on the motherboard, socket, or cooler plate? Which thermal paste was applied? Did any of it leak between the IHS and cold plate at that spot? Was anything dropped, spilled, or dropped onto the socket? Following the earlier advice, download and execute Prime 95 with short FFTs for an hour. If everything functions normally, it's likely fine. But if you're using your CPU's integrated GPU for the monitor, run Furmark for an hour and check for visual issues. As long as tests show no problems, it should be acceptable.
