AMD Ryzen 3700x overheating issue on the heatsink
Your motherboard suffered damage after being fried, forcing you to replace it. While rebuilding your PC, you encountered difficulties removing your AMD CPU from the heatsink. You applied the thermal paste incorrectly, used a hair dryer repeatedly without success, twisted the CPU, attempted to scrape it off with a blade, and soaked it in isopropyl alcohol before trying again. Now it won't budge. Consider consulting a professional technician or checking for hidden components that might be obstructing removal.
Typically, you simply grasp the sides of the CPU and give it a firm twist; it should come out easily. A sharp movement usually does the trick.
I've already attempted flossing but couldn't reach the area. I gave it my best effort—tried to move it, but it stays in place. Even using a hammer safely didn't help.
You've apparently done everything possible, but it seems the CPU is firmly attached to the heat sink. Pushing too hard could damage the CPU or detach the heat spreader. Since I can't inspect it directly, the best option is either to remove it and install a new one or swap both the sink and CPU until you find a solution.
I began to consider that. Examining the images attached earlier suggests the gap between the IHS and the heat sink appears quite reflective. I can't be sure one way or the other, but if the CPU remains fixed there might indicate factors beyond just thermal paste.
Obtain a adjustable wrench. Hold the heat sink tightly as you rotate, either straight on or by twisting. The tool provides you with leverage. Success is assured.
I would use a sharp blade and strike it with a hammer to push it into a corner.
