They are both 1000's and I have a 2000 on the front drawing air in. Now the 1000's are very very quite and the 2000's are nosiey as you like.
I added one of these - http://www.overclockers.co.uk/showproduct.php?prodid=FG-006-GE
to the front connector as I have it going straight up the back and connecting to the psu this takes the fan down to around 1700 rpm and the noise different takes it down a noise category if you know what I mean. Sounds very good now and cooling hasn't been noticeably effected.
The fans are great and the fact they come perfectly braided is a bonus
