If you purchase a new processor then it will come with a fan so no need to worry there
Not true I'm afraid, a lot of CPU's (AMD in particular) come as OEM rather than boxed, if buying OEM then you would have to get a heatsink and fan seperately.
What does the MOB support intel or AMD, what type of memory does it support, does it support SATA etc etc, these things will be in the manual that will hopefully come with it.
I did a search for the MOB model you quote but could not find the model number you are saying the nearest I could find was a -800 not an 88.
I don't wish to sound rude but I think you should of done a bit of research first before buying!
