Lian Li PC- Q08 itx case : Specification & Feature

^^ .. so, even if you can fit the rad with the existing fan, you'll have open_outside_air->fan->radiator->PSU_wall kind of setup? Not very effective, I'm afraid.
 
I was thinking about this setup: radiatior with intake: 140 fan intake too: atx psu with the fan facing the motherboard, so it will put out hot air. it should work.....I think :D
 
Thanks for the information. This looks like a promising case. Can't wait to see some builds with an h50 in it.
 
.. and (@ those who said newegg is asking too much for this case) it's sold out already

i have my h5o pulling air out from the case, and it works just the same with air intake to case.

in either case, u can always position the fan outside the case and have the rad inside the case if you must, if u don't mind the look of extra fan outside the case. actually that's how mine is setup atm.
 
yes, that's certainly a possibility .. imo, however, that works against the purpose of the case (computer case) which is to enclose things ...
 
It's sold out at the Egg, anyone here manage to snag one? Pics when you get it? :D
 
They have the red and silver versions up on Newegg now too. Is it me, or does it look like it has better airflow than the pc-v351?
 
Not sure if anyone has posted this, but I emailed Lian-Li's tech support department asking what the max CPU heatsink height is for the PC-Q08. This is their reply:

Hi IsLNdbOi,

Thank you for your interest in Lian-Li&#8217;s products. 190mm will be the safe length for CPU heatsink.

Thank you very much.

I asked him twice. The second time, I asked him this:

So we can use a 190mm tall CPU heatsink even with a standard size ATX power supply installed?

Thanks again,

I think he misunderstood it. Case is about 8.9" wide, ATX PSU is about 3.4", take out about 1/2gap between PSU and side panel and another 1/2 for standoff and thickess of mobo.
8.9-3.4-.5-.5=4.5"=11.43cm
 
Yeah, he most likely misunderstood. Not that I was planning on using a tower type heatsink in it. I will be using a Corsair H50. Hopefully it will fit.
 
I'm tempted to get this case over the pc-v351 just because it looks a lot cooler, and holds more hard drives natively. Speaking of which, I'd think an H50 would fit just fine, especially if you were to take out all the hard drive bays and run them out of the 5.25" spot.
 
Ok, I asked him a third time:

Can you please make sure if they will fit before I order them? You say 190mm length, but I did not ask what the maximum length is.

I want to know what the maximum height / how tall can the CPU heatsink be, not the length.


Surely someone at Lian-Li knows for sure?

Thanks again,
IsLNdbOi

Dear IsLNdbOi,

Sorry for the big mistake previously. I didn’t calculate the distance of PSU and it makes there is only 100mm left for heatsink.

Sorry for the wrong information again.

Well, there ya go. You can get a tower hsf in there if you remove the PSU, which is optional anyway. ;)
 
When I was planning to get one of these, I figured you could just stick an H50 in the top exhaust fan. Remove the bottom HDD cage for big GPU's and you got plenty of space for a nice mini-itx gaming system...

But blah, I think I'll be going back to a regular ATX again... D=
 
My guess is the issue will be significant part of the radiator (and fan) being blocked by the PSU ... otoh, putting H50 in the front is not exactly straightforward, as that fan is 140mm and H50 uses 120mm mounting holes.

Whats wrong with that idea?

Yea it would be blocked, but probably work better than any other low-profile cooler you could stick in there.
 
mmm, ill still wait, have a shop whos got pre order in say they will test an h50 in one for me :)


OTher than that, custom watercooling (240rad in roof) ;)
 
I bet the h50 would fir at the top & Would still work fine even though the PSU will be doing its damnedest to block its airflow.

Air moves in the path of least resistance. So even though the PSU may be blocking a fair portion of the airflow, the fan will still suck the same amount of air out. Where that air is coming from is a different story that can only be told by thermal imaging.

I agree with the air moving/expanding toward the area of lower pressure (and that's what a fan effectively creates in front of itself by moving the air that was just there out). I don't see how this leads to "the fan will still suck the same amount of air out" conclusion between the partially blocked and unblocked situations and would appreciate if you could explain the physics behind it.
My take on this is as follows:
1. Consider a fan flat against a continuous wall. How much air will it push through? Zero. Consider a fan fixed in the middle of a large volume, far away from the walls. How much air will it move? A theoretical fan MAX. Now, barring any type 2 phase transitions, most physics phenomena are smooth/continuous changes. With that, I believe, changing from "up against the wall" to "in the middle of large volume" situation will result in a continuous and smooth change in the amount air pushed through by the fan ... which leads me to think that the situation with partial blockage is worse in terms of airflow, not to mention a potentially shorter lifetime of the fan due to uneven wear on the bearings.
2. Think of a container with a small hole and higher pressure inside than the outside pressure (that's what the fan effectively creates). Will the pressure equalise quicker if the hole is bigger? I think so (and the examples are plenty)

Now, I just looked into OCZ ModStream 600 PSU -- it has a 90 degree sector toward the meshed/exhaust side of the PSU below the fan blocked by a piece of mylar. I believe this is done in order to make the air flow around PSU components before it exits. If what you are saying were true, OCZ would have been better off blocking all of the fan opening except, perhaps 10% toward the side with the modular connectors, as this would result (according to you) in the same amount of air travelling through more of the PSU components on its way out through the meshed side. For whatever reason they did not do that.

The case seems great, but i really would like to see it in proper steel. this case only weighs 2.73kg. I just find that stupid :)

I'm saying that even if there is a gap, air will still flow through. Your example of a fan against a wall makes perfect sense only if the PSU is right against the fan. If it's not, then air will still be sucked in through the gap. The point that I was making was that even if the PSU is close to the top 120 exhaust, air will still be exhausted out of the case. The only difference between a small gap and no gap is the area of air that's affected. In an open-air scenario, air from all directions will be sucked into the fan. When blocked by a PSU, the areas behind the PSU don't feel the effect of the fan, and thus the air in these areas doesn't move. The fan is still pulling the same amount of air through though.

As far as uneven wear on bearings and whatnot, I'll agree with you. The differences in pressure over the long term may increase wear unevenly.
 
no, the amount of air moved lowers drastically, though the loss can be mitigated using the proper fan. try using a fan with and without a filter, you can easily feel the airflow difference with your hand.
 
Has anyone seen a mITX motherboard with USB3.0?

This is the only way I've found (without using most mITX boards' PCIe 16x slot) to get USB3.0 for the PC-Q08's front USB3.0 ports. This only works though if you have a mITX board with a mini-PCIe slot.

USB3.0 Half Mini Card
http://www.iointerconnect.com/c0_1.php?pid=6&bid=2&cid=17


I haven't found any place that sells it.
 
Nice. Don't have the money to upgrade to a new motherboard and new processor though.

I wonder if the company that makes this mini-PCIe USB3.0 card can sell to end users...

doesnt matter.. Ask the manufacturer of the board your looking at & they will msot likely tell you that the mini pcie slot only supports wifi. I Got that from 2 manufacturers already.
 
Nope. Zotac technical support has stated on the Zotac forums that the mini-PCIe slots on their motherboards will work with any mini-PCIe card.
