Hi this is my first thread. I am currently running an old dell computer which i have upgraded every now and then and I have bought a new case for it. The thing is The dell i have at the moment has a fan that is connected to the back of the computer on the mesh and has a tunnell that directs the air to the CPU. I have another CPU fan but it doesnt fit as the conector is strange.on the motherboard. What do i do? Will I need to buy a new motherboard for this new case? Or wil there be a fan out ther? Im not sure of the make of the motherboard But When i find out I will Post it up.
