Double radiators on bottom of case? - Page 2

post #11 of 27
Thread Starter 
I'm liking the thought of having the radiators INTAKE on the bottom since that's where the cool air is, but correct me if I'm wrong because looking at this diagram, I don't know what would happen in the middle there.

If you outtake, you will be getting rid of the cold air. I think it would make more sense to outtake where the actual components are?

Please correct this if it's incorrect.

What happens when 2000+ RPM fans are blowing air directly inwards and towards each other as the diagram suggests?

I think you should put an exhaust fan on the question mark area.

The question marks are there just to represent that I have no idea what's happening when the air from the radiators is being sucked in. These are 3000 RPM fans so I'm not sure if that will cause issues with the air intake. Does anyone know?

I think only one of the red question marks can be used for exhaust anyways. Is this advisable?

best setup here. but recommend putting a divider in the middle to eliminate turbulence.

What kind of gap is there on the inside between the two radiators?

Your drawing at the top illustrates my point, I would NOT have the fans pointing in because they would fight each other. Put a intake fan blowing cool air into the space where your ? is and have the rad fans blowing out from the middle. The closer the two rads are the more this flow makes sense. Coolwaters has it right.

Why is this the best? Would push/pull in this formation be better or just push? Why not intake the cool air in?

What about the top chamber of the case? Should I have these regular fans intaking then?

Someone posted in another thread that bottom radiators should be intaking so that the above vents don't intake used air if the radiators were set up to exhaust.

I appreciate the input, just looking for some evidence!

Thank you!

EDIT: Just saw your post Rat. That makes some sense to me. But why have an intake fan bringing cool air in only to exhaust it right back out? What about the top chamber (which is completely separate from the bottom)? Should I use the top vents to outtake and the front vents to intake? I don't believe I will have fans on the back unless I should. Should I?

i take it you have an M8 with the pedestal? if so, the rads being in that bottom pedestal exhausting hot air out wont affect the rest of your case, the air will hit rom temp before the heat travels that high.

I'm actually planning on getting an SMH10 when they're released. It's essentially an STH10 with the top chamber removed. This is what this build will be for.

I'm just trying to figure out what will be the most efficient way to cool since in the M8, I had two radiators top mounted venting out of the case and the rest were intaking, which made sense since they would bring in cool air and since heat rises, it would vent out the top. I'm sure there were some holes in this theory as well since the radiators perhaps were hotter than normal since they were up top and venting out?

Do radiators work better venting or intaking? Does location (top or bottom) even matter?

Radiators work by having good enough air flow to effectively carry away heat The main thing you are trying to do is get that good air flow through the radiators. Having high speed fans face each other will cause buffeting which could stall the airflow and make the middle a high pressure area. It would be much more efficient to have them face out so the middle is the low pressure area and maximize the flow of air through the rads. Since you are pulling in room air, pushing it through the rads and out you will get the best performance in that setup.

In the end the slight delta from either set up will be trumped by the efficiency of those dual monster radiators. You will have more cooling performance than your setup will need and the few C's of difference will have no impact on how much you can overclock. Your CPU and GPU's will probably top out before the thermal load becomes an issue given the setup your talking about.
