Yes fans on A1 sucks. Sometimes they even aren't stable on the cpu. I replace mine with another and clocked my A1 to 1000Mhz.
Anyway it is not the reason of underclock. But bacause the first models had a 800Mhz cpu, later the same model at the same price was selled with a clocked down 933 to respect adverstisment.
I suggest to post your auction on calssified on aw.net, a lot of people are interested in XE.
