Hii I have a Dell Inspiron 537(not the slim) and it currently has the 0U880P motherboard and I am wondering if I can upgrade the Intel(R) Celeron(R) CPU 450 @2.20ghz 2.19ghz to an Intel Core 2 Duo E7500 Processor 2.93 GHz 3 MB Cache Socket LGA775. I have updated my BIOS to A03. I have done tons of research and I noticed this CPU was supported but I just wanted to make sure on my own that the CPU will work with my motherboard. Also I am having trouble finding a heatsink fan to go with it, any suggestions?
