If your motherboard is running hot, or guide you on how to safely remove the heatsink . Let me know which model of Case you are using so I can suggest appropriate cooling solutions .
Ensure the chassis has a fan pulling air over the motherboard area, even a small 40mm or 60mm fan can significantly lower temperatures on a passive board. intel d33025 motherboard specifications hot
Here is the secret: While the Atom CPU is low power, the (the large chip next to the CPU) is an old desktop chipset built on the 130nm or 90nm process. It was designed for Pentium 4s, not Atoms. The 945GC can draw 15W–22W on its own, and on the D33025, it often sits right next to the CPU with no active cooling. This heats up the entire PCB, raising the CPU temperature indirectly.
