Antec Lanboy Some advice on cpu fan air flow

post #1 of 13
Thread Starter 


Hey guys, I have an Antec Lanboy air case. Antec recommends putting all fans as intake no matter where the location is. This is how it currently looks like...

- One 80mm Masscool fan to blow directly on top of the RAM chips (I couldn't fit a 120mm in there cuz of my CPU cooler
- Two 120mm stock antec fans on the side to cool GPU and sound card
- CoolerMaster Hyper 212 Plus with optional 120mm in push/pull facing UPWARDS (pretty much an exhaust since the top of the case has vents)
- Everything else is stock antec intake fans

So my main question really is, should be CPU Cooler be facing in another direction per Antec's recommendation? I mean the way it sits right now is pretty much an exhaust. I was fearful of pointing it DOWN (intake) because it would heat up the GPU/Sound card. And I don't know about pointing it to the rear, because the rear fan is suppose to be intake (too much turbulence?). So Should I point it towards the front facing the ram chips?

Any input would be greatly appreciated! Thanks

In that case the goal of a fan is to blow directly at the components that need to be cooled. Most newer video cards can run a bit hotter while remaining well with in tolerance. I would go with what Antec recommends.

Well, with all of those fans blowing air into the case, you should end up with a positive pressure zone. as a result the top of your case is already an exhaust, so I would recommend keeping it the way it is, because the other orientation will disrupt the flow of air in your case... But then again, I am not a professional.

So would you recommend facing the CPU cooler towards the front or down?

Well the way I have it right now, my CPU cooler is pulling hot air from the case and pushing it through the top of the case (vented)

The antec insturctions doesn't say anything in regards to CPU cooler and which way the fan should be pointing. It only mentions all case fans should be pointing INWARDS

I'll probably shoot Antec an e-mail...and hopefully they give me a good answer....then I'll update my thread title so anyone else who buys this case won't be confused

Push comes to shove, you want to go with the flow.

I would not put it blowing on my RAM.

I'm a positive pressure, air channeling,and leak tapeing kind of guy. So I'm not real fond of the Lanboy, but what I would do personally would try the different configurations. That's why we have temp sensors; besides, thermal paste is cheap.

That hyper 212 is fairly narrow. How much room would be between it and the Video card in a downward orientation?

it fits fine...plenty of clearance between the sound card and hyper 212, looks like 4 inches? video card is even further down....if I want to force air down, then I just switch the fans...but if I want to go side to side (front or rear) then I would have to pull the cpu cooler and reposition it...which is kind of a *****...haha

Well you can test two of the four evils with out pulling the cooler. Let me know what you come up with.
