ehume I just did that experiment in item 2 . . . as an experiment. I wanted to see what a push-pull could do. Since then, I suck from the front and let the air find its own way out the back. The experiment only showed that the pull fan of a heatsink could evacuate a case.

TELVM Interestingly I always do almost exactly the opposite of what you describe in item 2 of your sig, ehume.

I cover and seal air tight each and every opening in the case, except those in front of intake fans and those behind exhaust fans, which I clear to the utmost. And I'd never left the back or the top rear exhaust fan positions unpopulated, nope nope.

More than one way to skin the cat I guess :-) .


My 2600X with an NH-D15 ontop maxes out @ 54C / 129F running Cinebench R15 (22C / 72F ambient):

Empty rear window.

I leave my rear windows untenanted after I remove the grill. Instead, I use the pull fan on whatever heatsink I am using to entrain case air and exhaust the case. Item 2 in my sig illustrates the method. But one thing I have learned over the years: Gorilla tape will do a fine job of covering the cut edges.

^ Wise words from ehume there.

I can physically feel the air off the front fan exiting the back of the gas against the glass side panel. This is why open test bench test results aren't always indicative of real world performance.
Now, if you really want to improve your case airflow you will take some tin snips and cut away the rear "grill" of your case. It is really not a grill but a perforated wall. See #2 in my sig for an old trial of this. You cover the cut edges with Gorilla tape, and if you have a problem with little fingers, there are finger guards for sale: you use fan screws and #10 nylon license plate nuts (available from auto supply stores) to hold them on.

I love the D15, but I also love the D14 with new fans.

It beat D14 by 1-2c on i7 920 @ 4.3GHz, and D14 is as good if not a little better than D15, so yeah it is better .. also about $50 which is a steal for how well it performs.

It is also less money with only one fan that you plan replacing with TY-143's anyway.
But TRUE Spirit 140 Power with TY-14e's is even better if it will fit.

Bottom line, my AIO is dead and I'm having second thoughts going to AIOs again ... I have 2 of those fans here and I remember that on the NH-D14 there was a 8º improvement... curious about D15.

Thank you all!
