Code: Select all
boot_delay=1 initial_turbo=30 arm_freq=1050 core_freq=500 sdram_freq=500 over_voltage=4 temp_limit=70 gpu_mem=320
The high one is very good for the fan, as its height does't create problems for the fan placed on the top, while the small one is perfectly sized for the SOC (using the middle line), and the usb/ethernet chip (using a lateral line).
Which one do you suggest me for cooling?
Also, do I need a thermal adesive or only a thermal paste?
If in your opinion I don't notice a significant temperature difference between the 2 types, will you suggest me one of them or a part of each one (for praticality)?
I tried to connect the fan to the first 2 right GPIO (5V) but it didn't start, when if it is connected to my PC motherboard (12V) it starts, what do you think the problem is?
Is my setup safe or would you change something?
I know that these are a lot of questions but I didn't want to open a lot of different threads only for me, and I'll be glad of any of your answers, thanks in advance
