I recently acquired a new Gigabyte K8N Pro and a AMD64 3000+. I got the Thermaltake Polo 735 and i cant seem to figure out how to secure it to the motherboard. The fan came with large screws to fasten it down, but the holes are too big for the screws. Is there a special trick to this? or do i need to just got out and get some old fasion bolts and washers to fasten this thing down?
