Im glad it all worked out for you! You've done really well to not have the cooler blocking your first RAM slot too
Just to note: Im not sure if your using 2 RAM sticks or 4, but if your only using 2 sticks, most motherboard recommend using slots 2 and 4 anyway. So if you are using 2 sticks, and using them in slots 1 and 3, id have a quick check of your motherboard manual to see which slots it recommends.
EDIT: Thats a really impressive temperature drop aswell!
