How to cool Define R5?

Hey guys,

 

I tried to think of a good way to cool down the R5 and I've found the following setups. Please tell me which one is better and why~ You guys are pretty much all a lot more experienced than I am. :)

 

Please note that I really really don't want to remove the top moduvents...

 

1) Setup A:

Front: two 140mm fans + 280mm radiator + two 140mm fans (push/pull), intake

Bottom: one 140mm fan, intake (with a 280mm rad, there's no way to put another fan in the bottom)

Rear: one 140mm fan, exhaust

Similar to this build: http://pcpartpicker.com/b/QwJV3C

 

2) Setup B:

Front: two 140mm fans + 240mm radiator + two 120mm fans (push/pull), intake

Bottom, two 140mm fans, intake (with a 240mm rad, two fans can be installed in the bottom)

Rear: one 140mm fan, exhaust

Similar to this build: http://pcpartpicker.com/b/j7HNnQ

 

3) Setup C:

Front: two 140mm fans, intake

Bottom: two 140mm fans, intake

Rear, one 140mm fan + 140mm radiator + one 140mm fan (push/pull), exhaust

 

What do you think of those three setups? Which one is better?

Also, will it help the temp if I install another 140mm fan on the side panel as intake? (It's a bit inconvenient but if it's very effective, I can take it, haha)

 

Any help is appreciated! :)

Could you tell where you plan to place the rad and if the front are intakes or outtakes?

Yeah, right guys? Guys?

I did specify where to put rad and intake/exhaust in all three of the setups.

You should probably use the top as an outtake radiator spot...

Yeah, but I really really really don't want to remove the top moduvents...

So in the first one you mean all the stuff under front in intake?

Yeah, right guys? Guys?

option a looks to be the best balance. most fine filters are restrictive 40-60%, so

two 140 in (filtered) and one 140 exhaust will give a slight positive pressure for

dust control. push/pull is not necessary as plans are to run the fans slow and

4 fans makes more noise than two. the 2-4° possible temp drop doesn't warrant

the extra cost. the extra fan on the floor is optional, but unnecessary.

 

option b is wasteful and will cause noise and unbalanced temps as the 140/120

combo will have no equalization.

 

option c i do not recommend single fan radiator AIO, except for GPU cooling.

yes. you can also check out the build I listed that's similar to the setup.

So you suggest to put two 140mm fans + rad in the front, pushing are in; and then one 140mm fan on the rear side, exhausting hot air out?

The reason I want to add bottom fans is because the air pushed in from the front is hot because of the rad. I fear the temp inside the case will be too high without a cool-air-intake. What do you think?

it is kinda the trade-off of "silence" and not using the roof as an easier ventilation

option.

 

option d would be the 2 front 140 fans, one 140 floor fan, AIO in the roof (exhaust)

and flip the rear i/o fan to filtered intake (unless location is in a cubby, then exhaust).

I would choose whatever cooles the rad best and creates negative air pressure, since negative air pressure results in the least dust.

Silverstone has a great article about positive vs negative and other airflow related stuff: http://www.silverstonetek.com/techtalk_cont.php?area=en&tid=wh_positive

I'm pretty sure positive air pressure results in the least dust. Even the link you provided suggested so...

Right, I know the option d you provided is better at cooling the temp down. But at least for now I really don't want to take the top moduvents off... I guess for me, I'm willing to take a bit of the trade-offs of silence, haha. :)

Sorry, I mixed to two, I ment positive

If I ever get a Titan X, do you think mounting a gpu cooling rad (something like nzxt kraken g10 + x41) at the rear exhaust fan spot is a good idea? Given that the rest of the setup is similar to setup A.
