Noise and Thermal Testing, Overclocked

Lian Li's PC-A55 is the first time I've actually been nervous about thermally testing a case. The CPU cores were already pushing the mid-to-high 80s at stock settings under load; how was this whole thing going to fare when I bumped up the clocks and pumped more voltage through the CPU and graphics card? As it turns out, it wasn't going to fare well at all, and I'm thankful we live in an era where our hardware has thermal protections in place. Ten years ago, I likely would've had to replace most of the testbed after this.

CPU Temperatures, Overclocked

GPU Temperatures, Overclocked

SSD Temperatures, Overclocked

On the charts it doesn't look as bad, but keep in mind that the Intel Core i7-2700K's cores were actually hitting 95C with the case elevated, and 98C without. The GeForce GTX 560 Ti was also peaking at 95C. All of this in a room with an ambient temperature of about 24C, a temperature which isn't terribly uncomfortable or unreasonable. If the PC-A55 had a hard time dealing with a stock system, it flat out couldn't deal with any kind of overclocking. What's worse, look at how heat builds up around the SSD and imagine what would happen if a mechanical drive were used.

CPU Fan Speed, Overclocked

GPU Fan Speed, Overclocked

Our Cooler Master Hyper 212 Evo was being pushed as hard as it possibly could and the CPU thermals were still hitting the maximum spec. The normally efficient custom cooler on the ASUS GeForce GTX 560 Ti had just as hard a time, with the fan basically maxing out under load. Lian Li's design has virtually no thermal headroom. With the elevated testbed, the GPU does better, but even so it places last out of our set of cases.

Noise Levels, Overclocked

The PC-A55 basically winds up being our worst-case scenario on almost all fronts. While it remains quiet at idle, under load it's very noisy and uncomfortable to listen to, due to the fact that the fans running inside are all going at full bore. As a side note, because of the aluminum shell, the top of the case was actually almost painfully hot to the touch when tested under these conditions. Putting the case on a flat surface helped thermals a bit, but also gave noise one more place to escape, causing it to run even louder.

    I'm a Mac junkie now, but rewind 4 years back and I used to build my own tower PCs like no tomorrow. I loved to pick out the best of the best components and put them together only to sell what I had done and start over again. To me, Lian Li has always stood for excellent looking aluminum cases, but they were bloody expensive then and are still today. I dreamed of a Lian Li case bak then, but I never got to build a PC with one of those beauties. :( It's great to see them still making top-notch stuff, though. Some of the better companies faded into oblivion, like SuperFlower. CoolerMaster used to make some good stuff back then, but no longer. :/ I'd put my money on Lian Li if I still had the passion to build tower PCs.

    ...did you actually read the review?
  • JarredWalton - Saturday, June 16, 2012 - link

    I'd guess not. He looked at the picture and said, "That's a nice looking case!" Too bad it doesn't have the performance to back it up, unless maybe you just want to run a Core i3 CPU with now discrete GPU? Buying a $110 case for such a PC seems a bit much, though, and it still performs like A55.

    There is a smaller ATX case, the Lian Li PC-V700. It is 21 x 40 x 50 cm. And it holds six 3.5" disks.

    Yeah. I have a PC-G50. It is smaller than this ( 14.5" tall or so ), and has 3 3.5" drive slots. With the Add-on 4in3 bay adapter, I've had 7 HDD in it at one time. Plus it added a 120mm intake fan into the mix.

    It is not the perfect case for a couple of reasons. but I am very happy with it. However, it is by far in my mind a better design compared to this.

    Move the PSU horizontal, sideways, and reverse ( with perhaps an adapter cable going out to the back ). After removing the drive bay from the bottom of course.. Then add ventilation for the PSU intake, front, or side ( both ? ). Just thinking out loud here . . . Still lots of things could be done to improve this design. Obviously.

    My guess is that this person did not read / understand the article title. Never mind the article its self.

    One thing you do have to keep in mind however. Individuals have a mind of their own. Just because you or one of your cohorts gives equipment a bad review. Does not mean that someone else has to agree.

    And there is a lot to disagree with sometimes, from the articles / reviews presented here. Everyone's priorities are different.

    Hehe, yea, I was just about to ask the exact same thing! Thank you for the in-depth and informative review, appreciated!

    Lian Li makes some great cases, this may not be one of them but there are a lot of other models so if you like the look of this there probably is a case for you in there somewhere. I have a PC-9F that is quite similar but a bit bigger than this that's just great.

    If you use Macs then what in the world are you doing on this site poser? This site is for computer enthusiasts and those into the latest and greatest, open standards and system, fastest machines around that can be upgraded and overclocked. Apple products don't fit under any of those headings. Maybe if we created an "overpriced preschool computing" Apple would fit nicely. No one wants Apple crap around here buddy.

    Who made you boss, kid?

    It sure was that guy Anand, who probably owns every Mac ever made.
