Fractal Design S - best static pressure fan? Noctua - Thermalright - Phantek? please help - Page 6

post #51 of 109
FD Define (S/R) is geared more towards more silent operation. (The S a bit more as the R)
But because of the front door, it has more difficulties "breathing" compared to the ARC.
Thus the Define will always "run hotter" compared to the ARC. Cases geared towards "silence" almost always run hotter as their "regular" counterparts

Of course it is possible to make the Define "breathe" more.. just up the fans & fan speeds... but that kinda cancels out the whole "silent" part.

I would not be surprised if in the same conditions (ambient temp, load, incase temp) the ARC would actually make LESS noise as the Define.
Someone should do this test... since the ARC & the Define are virtually the same case, except for the front door. smile.gif

All very true.
I will only add that with the Define R2 to R5 having a door in front make it very easy to increase front intake area by simply opening the door .. for those few times the system in them is running extreme loads. wink.gif

I just noticed you can't take the front door off from the define S lol. How much of a difference in temperature is it when you open the door?

This will be a factor of the static pressure of the fans (thread coming full circle lol). More static pressure will allow the fan to pull air over obstructions at a higher rate, so with a fan optimized for static pressure the change will be smaller than a fan with lower static pressure and similar flow. Either way you will get a higher flow but the amount of change will be based on the static pressure.

As said, depends on fan pressure to some extent, but even using 1.5 -2.0mm |H2O fans I could see 4-6c lower temps and fans ran at lower rpm with door open. All of my build have case fan speed temperature controlled by CPU and/or GPU temperature.

I don't have any data of actual airflow area of the strip vent on either side of case, but it is significantly less than with door open .. maybe 20% as much?? I've probably already said you might find some of the articles in "Ways to Better Cooling" of intereest. Link in my sig. Opening post is index, click on topics of interest to see them.

Uggg, I guess the thing I like about the r5 and S is the sound blocking front and top, I guess I would simply pick a case thats designed for higher airflow before cutting up front.

I settled on the R5 last night, I guess if there was a real hot day and I needed more ooomh on cooling I can jsut open its front door

lol yes indeed.

I think if my fans ever went to max here, my boxer would decide the computer was alive and take it out lol

Not necessarily. A fan's static pressure on output does not always directly correlate to ability to draw air. In fact, some fans noted for their high static pressure are notoriously bad at their ability to draw air through any type of restriction.

Static pressure is rated on the exhaust of the fan only.
