Double radiators on bottom of case? - Page 3

post #21 of 27
Thread Starter 
Thanks Rat.

Since these are completely separated from the rest of the rig, I assume they will just be essentially heat dissipation radiators.

What about the main chamber?

Would it be smart to have three fans on the front at 1450 RPM intake and four fans on the top at 1850 RPM exhaust? How would you work with this area since the radiators have no effect on the chambers airflow?

What about the "stray" fan on the bottom where the radiators are? Intake or exhaust?

Not sure I am following about the "stray fan" on the bottom. If you mean in the lower chamber, have it suck air in, push it between the rads and then the fans on the rad push air out each side.

For the case proper, your thermal load will be minimal from just the HDD, Ram, and mobo VRM's (assuming you are not using a mobo block). With that many fans moving air you will have more than enough airflow regardless of the config.

The real question you are asking I think is negative or positive airflow. I think this is more of a matter of personal preference as the benefit of positive (air coming in faster than out) is it can lower the dust inside your case assuming filters on your intake fans. Negative airflow (air out faster than in) supposedly removes heat a bit better but I think the difference is negligible.

I think you could save some cash on case fans and just have one out the back, one out the top and one or two on the front. You can do more for visual balance and allow you to run them all slower (quieter) but I don't think it will make much difference on your thermals since the majority of the heat will be dissipated by the water loop and out the rad. in the chamber below.

I was thinking something like this:

Any potential conflicts?

Thank you. I may use the back fan vent as an intake but I haven't decided yet. I don't want to deal with an air filter over there but I'd rather confirm that I have positive pressure rather than cut it close and have air/dust squeezing in elsewhere. That way, there will also be cold air blowing on the CPU/GPUs as well just in case.

Any other comments, concerns?

besides the GPU (if its not water cooled too) the rest of the components shouldn't generate generate a lot of heat.

blowing throw 2 radiators with the same air pretty much brings down the cooling potential of the second radiator. you will start to "feel" it in a stress test. my single 240mm radiator with a lot of air blowing thought was really warm on a stress test after 20mins.

bring in as much air as possible with the rest of the case fans and have it all blow in and exit through the radiator. IME thats best.
