Pull is not always better than Push as some people will tell you. For example, in my TJ07, I have my fans set to push and intake cool air from outside the case.. rather than pulling hot air from inside case and exhausting it out. This results in much better performance. The most important factor is that you intake cool air from outside the case
, and if you can accomplish this with pull then that is advisable, but push is acceptable too. The reason I cannot pull from outside air because trying to pull through radiator, and the sidewall mesh is much too restrictive.
There is only Â± 1 degree difference in fan orientation, but if you increase the ambient air temperature by 10-15 degrees your results are going to be drastically different.Edited by nettwerk - 7/4/08 at 7:08pm
