I recently got a acer aspire running linux debian 8.3. I want to do some upgrades like ram and maybe the proccesor and maybe the gpu. Just to make it a bit faster. Also is there anyway to upgrade the cooling?
By the time you upgrade the components, you would have spend enough to get a fully working system that is newer, I would not bother upgrading the system, sell it and use that money towards a faster one. A used system with a Core i5 CPU would be not much over $100 for a first gen i5. And an i3 would be even cheaper.
