Need Advice On My Air Cooling Setup

post #1 of 7
Thread Starter 
So my case is a Lian Li PC-A70F. It has two 140mm intake fans and two 120mm exhaust fans...

I've replaced the front intake fans with these Xigmatek fans..

And rear fans with these..

As far as a CPU cooler i'm going with a Noctua D14 since it will be on a Z77 mobo and Ivy Bridge CPU.

Ok heres my questions... I wanna go with a fan controller since i don't wanna molex all these fans and run them at 100%... Here is the controller i'm leaning towards.

Is this a quality controller or should i be looking at another. I will need one that will control at least 6 fans.. Also is my fan choice good?


My main question is should my rear exhaust fans be pushing more rpm's and cfm's than my cpu cooler and intake fans?

Yes that`s a good fan controller, and rear fans must have higher CFM than front fans!

And DONT get NH D14 get NH C14 or TR Archon or Prolimatech Megahalems or TRUE 120 black those have less weight and performs near, also would be enough for 5GHz i5/i7 IB

That's a good controller.

The air coming from the cpu cooler is going to be slowed down quite a bit by the heatsink, so really you just need enough exhaust to remove the heat it produces (or rather, displaces) and keep the front to back airflow in your case moving nicely. The Lian Li is very streamlined for this, so you shouldnt have a problem keeping things cool without up speeds. I would set both front and rear case fans at 800rpm, check temps, and go from there. The Lian Li may come with splitter cables that allow one end to go into the mobo for rpm monitoring.

imo the NH-D14 is a fine choice.

Well my front intake fans at max are 1000 rpms/65 cfm. The exhaust fans are 1800 rpms/ 75 cfm. So the exhaust are slightly higher. Also got to consider air will pass through the HDD rack. If i have my HDD's and SSD there, that will slow my air flow down too.

I was considering the D14 and Silver Arrow but i couldn't find anywhere yesterday when i was checking for everything so i went ahead and listed the D14 as my choice. Haven't actually bought a CPU cooler yet so it may change by the time i get everything.

I say you NH D14 is HUGE, better going H80/TR Archon(dual fan)/Megahalems Push pull(XSPC/NF P12/Scythe Slip Stream kaze jyuni 110CFM)/(XSPC Xinruilian 2000 RPM /Noctua NF P12/Scythe Slip Stream kaze jyuni 110CFM)/TRUE 120 Black(XSPC Xinruilian 2000 RPM /Noctua NF P12/Scythe Slip Stream kaze jyuni 110CFM)/TR venomous X rt 2x stock fans, NH C14

those are a bit smaller and have the same performance or even more depending if Megahalems or any other like megashadow,Super mega, Venomous X/XRT push and pull

I`m talking about this bcuz I have one NH D14

Dude. Look You have a natural. Don't waste any time or energy with exhaust fans. Your big aluminum case comes with empty spaces where steel cases have grills. Those of us with steelies have to buy a special nibbler to get rid of our rear grills, and here Lian Li has done it for you.

 

Look at item 2 in my sig. If heatsink fans can draw that much air through a case, why bother with exhaust fans?

 

Instead, put a 140mm fan in your five-slot 5.25 bay. That will even give you moar intake, some of it in a direct shot to your D14.

 

If you r-e-e-e-ally want an exhaust fan, put a third fan on the D14 (Noctua will send you the hardware free if you ask them and include a copy of your invoice in the request). Then you will replicate my rig from item 2.

 

Oh. Be sure to remove all the unused slot covers from your backplane.

 

Have fun!
