A noob question before i finish up my build tonight, so i will be installing the Rad (H100i) inside of my top Rosewill thor case. So in order to make the fans PULL AIR the front of the fan should be up looking at the top of the case or looking down to the case. Yea is a noob question but i have been working on my build all day and im burned out... you how is that feel, when you can't think straight no more jajajaa.
Use a proper fan on the radiator. If you were to use a pressure optimized fan and not the cheap junk that came with the "kit" you would have the exact same temperatures. It is also much easier to clean a rad. using a pull configuration because you do not have to take off any fans. Just take off the radiator. Blow it out and you're done!
You don't want them pulling hot air from the inside of your case over your rad. You want them taking cold air from outside the case. This of course puts warm air into your case but as long as you have fans in the back exhausting your kosher.
Not sure on the exact cfm or count of your fans but ideally a slight positive pressure which this will also contribute.
In the end, no need to take anyone's word for it. Try both and let the temps tell you what you want to know.
