[LianLi] Epic fail: comparison of 7HX and A55B

post #1 of 12
Thread Starter 
This post is more of a comparison between the 7HX and the A55B

My goal:  Shrink down my i5-3570k rig down to a smaller case

What I'm using now:  Lian Li 7-HX http://www.newegg.com/Product/Product.aspx?Item=N82E16811112389

What I'm trying to migrate to:  Lian Li PC-A55B http://www.newegg.com/Product/Product.aspx?Item=N82E16811112376

 

SETUP:

  • I5-3570K @ 5.0 Ghz

  • MSI Z77A-GD65

  • SAMSUNG 120 GB SSD

  • 16 GB DDR3-1600 @2000 Mhz

  • Corsair CX-430M

  • Antec Kuhler 920


 


You can see that there is a significant size difference between these two cases.  It is nice that you can actually fit a full ATX Mobo in a case this size.

With the front cover pulled off you can see the fan configurations.  The 7HX actually comes with a total of 3 fans whereas the A55B only comes with 2.

It is all about that AIO water loop that allows me to crank the Ghz on this setup.  I just built a small stable i5-3570k for my mom using the stock Intel cooler, and it couldn't even clock all 4 cores @ 3.8 Ghz stable.  So this is critical.  The 7HX has the drive bays removed in this current setup since it isn't really needed and it helps air flow.

You can see that with the A55B, it has the 140mm fans setup in push-pull, so this is great for getting air across all of the other thermally sensitive components on the motherboard, like the VRMS, RAM, etc.  It also has the PSU front mounted, which is how it is able to shrink its overal height compared to the 7HX.  The PSU is setup for exhausting in the front, so it is an innovative setup.  I wanted to play with this case for the sake of a liquid Nitrogen project I wanted to get up and running in the future.  What is great with this, like all Lian Li cases so far is how modular everything is. The fan came out like a lego block, as did setting up the PSU without tools.  One very handy feature of these Lian Li cases is the ability to easily take panels apart to ease in install and cable routing.  Very nice.

One major negative consequence to having the the PSU in the location it is in is that it isn't easy to get to the power supply switch easily.  You have to pull the front cover off (super easy) and get your finger in there just to switch the PSU.  Kind of a hassle, but not a big deal in permanent installs.  If you're tweaking with Overclocking and frequently changing settings, it can be a hassle.

I finally got everything together and it worked ok.  Not too bad.  Clocked just fine, and the thermals were there.  But where the hell was I supposed to put the radiator now?  The A55B is absolutely not setup to accomodate any kind of water cooling.  There aren't even any ports to run water lines out of the case.  And If I keep the radiator where it is, there's no way a grapics card will fit in there.  So, for me, this was an epic fail.  I still think that this is a very well designed case, for someone running on Air.  So, if running on air is your goal (air heat sink fan) then this is a great case.  Full ATX and full graphics cards with good airflow.

 

Even in this half-wit configuration with the rad just sitting around, I benched it hard with IBT and the case closed and it still performed like a champ.  There are just all of the future issues to deal with that are going to limit what I'll be able to do with this case.  Ivy-Bridge 3570k not being Sandy Bridge, it requires a good thermal environment.  So I'm going to put it all back in the 7HX.

IMG_3388

 

 

Here's the before when running on the 7HX.  I'm only benching hard on Linpack at 4.6 Ghz, because frankly, 5.0 Ghz isn't going to survive a crazy stress test like IBT at this point without the use of cryogenics.

7hx_46

 

As you can see on the A55B, not a change in temps really, nothing significant enough to warrant losing the ease of space.  It would've been nice to have a smaller case though.  I'll give it that.

In hindsight folks, I should've just gotten the right case from the beginning: http://www.newegg.com/Product/Product.aspx?Item=N82E16811112331

Why didnt you just get a 140mm to a 120mm fan adapter then connect the AIO to the fan at the top . If I went ATX the A55 would be my case but its a simple fix

You can fit a 12 inch card in there so one will fit you have to mount the AIO up top. You have options. You didnt seem to have a Graphics card from the start


What you need

Zip ties and tape would have worked fine. You could even find some string and tie it to the top fan hole.

I rather just spend $9 on the adapter then string. Zip ties can cause a big of shaking when the fans spin faster

That adapter would've been a good idea except that it makes the fans concentric. And the 120 needs to be offset from center from the 140 in order to clear the motherboard at minimum. I checked it up top and it couldn't clear the VRMs or pump.

what if you drop a fan and make it a 120 and the cases 140

You mean drop the 140's in the case to 120's? It won't line up to the tabs in the case. If you look closely, you'll see that the 140s are actually deeper than the mobos. Ultimately, there is a better case out there from Lian Li. I think they're clearing this case out for a reason. Still a great case for air use though.

I mean drop of the 120mm for 140mm and 120mm on the rad. If they are discontinuing the case I hope they replace it will just a design. I really like that cases size
