Question about CPU cooler upgrade Acer predator 3000 RTX 4070, how to keep cpu cool while gaming?

That is the one that most people here have used with great success on the Predator Orion 3000 systems. They use the slightly larger version on the PO5 and PO7 systems. No need to repaste or remove the stock brackets, just use M3x10mm screws instead of the ones supplied. Typically people see around a 15C difference in temperature at almost all loads. You should be able to add a heatsink to the SSD, but it's normally not needed. Where the SSD is located and where the memory is located is dependent on your actual model, they have been making Orion 3000 machines for many years now. Your full model number is usually on the same sticker as your serial number, it should look something like PO3-xxx-xxxx. Typically installing the one memory stick is tight, but doable even with the cooler installed.

Looking good! :)
