From my experiance if there is a difference it is ~1 degree so the less dust build up is more appealing to me. Ive never heard somebody say anything about more or less longevity in you fans before that is interesting. I cant see it making a huge difference in life span but maybe.... Have you experianced this?

I'm seconding everything MainStageNews has said; unless you're on a custom loop, or an AIO[All in one kit] with high FPI/thick rad (which I have yet to see in the AIO market) just run pull unless you like dust buildup in your case.

Honestly yeah there will be 1-2, maybe 3C difference depending on room temp and other variables, but nothing that will affect OC's.

I have lost a couple of fans pulling air through the rad when I first got into water cooling. Feeling how hot the air is coming out I just figured it wasn't a great idea in the first place. I haven't had one go out in push mode and I've been water cooled a couple of years now.

1c is no biggie for sure though but I do recommend some kind of filter (Pantyhose trick works better than nothing). My filters get dirty and cleaned every couple of weeks, my rads are clear so it's worth it to me.

Compaddict may I ask what kind of fans failed on you in a pull config? Were they designed for radiators because I could see a regular old case fan not designed for rads eventually failing but something like a Noctua or GT that are better designed for these type of applications shouldnt fail I would hope but I guess stranger things have happened lol

I can't give exact numbers (in terms of degrees), but I have never seen Push-Pull NOT give a 15-35% bump in performance (heat dissipation)....
