You will find using two fans instead on one leads to a great benefit in keeping temps close / at room ambient.. As for those specific fans - they should be fine.. Are they (Your XLFs) better fans? Define better? Higher airflow means better to you?
Then No - The one that comes with it has a higher airflow than those, but a higher RPM which means you can expect the XLFs to be a bit quieter..... However, you have two of these (well 3, but you can only USE 2 on the cooler, unless someone has some other ideas for ways to mount 3~) and only one of the fans that come with it... Either use your two XLFs or mix and match... it doesn't matter to me (because I'm sure the temp diff will be minimal -- but I know we strive for the best in this forum.....I just strive to make it thru another day
) but someone else can tell you what's best with that situation.
Will using lower airflow fans have an impact on temps over those using louder higher airflow fans? Yes. Will this impact be substantial? No, not if you're going between the default fan and the XLF fans...
Can anyone give you an exact temp variation compared to another higher flow fan? I bet someone will try - but honestly this is not possible to test for certain unless YOU do the testing in YOUR environment with YOUR case and YOUR setup...
Be happy you don't have to drop 20 dollars on higher speed higher noise fans... if those single digit temp differences become a bother - upgrade to louder faster fans... if not - don't give it a second thought and be happy with your new cooler! ^_^ Good luck either way, and enjoy the cooler. Even when I was using a single fan I thought it was a massive improvement over the cooler I was using prior.... and once I added that second fan - it just gets better and better~ Now - I can't stop recommending these coolers to peers and putting them in other builds!Edited by Ayekalooter - 6/22/11 at 6:45pm
