@george ok so i just figured something out. I removed my power supply hat that i have on my pi so i could connect my serial terminal pins and get you a log, and behold the suspend function works when i powered it on with the usb c port. so seems that for some reason supplying power through the gpio pins for some reason wont let me use the suspend function.

@zensation The radiator can be matched with raspberry pi. A separate fan is OK. Normally, it is not necessary to add aluminum alloy fins on the CPU.
