upgrade NH-D14 stock fans or are they good enough?

[Baumy15]

getting new stuff this Saturday and im wondering if its worth the extra $27 to get these 3 fans (in the part list) http://www.pccasegear.com/sc/fTl
or are the stock fans more than enough to remove heat? also are those fans good and reliable?

thanks

The fans on the NH-D14 are much better than those fans.

really? I know not to believe fan specs but I honestly thought they would be better? so should I remove them and get one for exhaust or forget about it all together

Their airflow is a little lower, but they have better static pressure and are much quieter. You wouldn't really need more airflow, but you could add one fan on the end of the cooler if you really want to be 100% sure you're getting the best possible performance out of the cooler.
