Upside down? The Lian Li PC-V1000B Plus II..

I am purchasing a Asus P5W DH Deluxe with an Intel Conroe.

I've heard you must invert the motherboard with this case. Anyone heard about this? Do you know of any articles discussing this?

How much impact with this have on cooling?

Thanks!
 
Will this impact cooling though? Some of the reviews seems to believe this inverted/upside-down mounting actually helps cooling.

Will it work with a Asus P5W?
 
It may cause problems. A32N I beleive had problems with upside down mounts.

The reason being is that hot air (and liquids) will rise to the top as opposed to go down. This being said the case has more heatsinks at the top where the liquid in the heatpipe would normally rise to. So putting it upside down would leave those heatsinks empty because the liquid is trying to move the heat to the top (which would now be the northbridge or southbridge i beleive?
 
I have the same case, and mobo. It was fine. If your going to be doing some heavy Ocing, then you might want to replace the heatsink. That is what I ended up doing.
Don't rely on the reported mobo temps. The onboard temp is from the SB.

I dont blame your for writing this, because there is alot of misinformation on this subject, but people really need to stop spreading this rumor.

I have built three computers using an A8N32-SLI in upside down cases (2x Lian Li PC-101, and 1x PC-767). Also I used a P5B Wi/fi Deluxe in a PC-101. All 4 of those heatpipe cooled computers are running cool and the motherboards dont even come near overheating. Actually the one in the PC-767's temperature dropped compared to when it was in a Centurion 532 right side up.

As I said, there is alot of misinformation on this subject from people who claim fact on something that they assume, but have never tried to test. The truth is, heat pipes do NOT rely on gravity very much at all. Think about a bit of water at the bottom of a straw, the surface tension and capilary action hold it in there, gravity doesnt affect it. That is why the wick is inside the heat pipe, to create a directional flow.

You will be 100% fine with a heatpipe motherboard in an inverted ATX case.
 
I was talking about convection not gravity. I just stated the reason some people had problems in the A32N.

Many other factors can affect the fidelity of the heatpipe cooling solution in a upside down ATX case.
 
Properly designed heatpipes are NOT affected by gravity. They work fine no matter which direction they're orientated.

The notion of warmer fluid rising to the top of their container is pretty much just gravity in action. And the heatpipes in modern PC equipment have no problem with this. They can be oriented in any direction.

A properly designed heatpipe has wicks in it and will function as well upside down as it will right side up.

I'm putting a p5b deluxe in a v2100b (inverted) and there shouldn't be any problems
 
i would not mount a mb upside down in that case . i've done my research and it shows that northbridge temps are higher in inverted cases. it's been done, but i wouldn't unless you're planning to get aftermarket cooling for your northbridge.
the case itself is great tho, great quality and cooling. and with my vf900 works wonders in it since the mb is upside down and the heatpipes are in the correct direction on the gpu

- What "research" led you to believe this?
 
Anybody know if a Tuniq tower will fit in one of these cases? I'm thinking about buying this case, it looks good.
 
Well I called Asus and they said don't do it. Their boards with heatpipes need to be mounted right side up. I bought a V series case when they first came out and had the A8NPremium board with it. It ran hot as hell so I replaced the case and had much bettrer temps. If the mobo manufacturer says don't do it you should probably listen.
 
I have had it go both ways using the LIan Li PC-V1000B. With my old mobo, an ASUS A8N Sli Premium the Northbridge was hot enough to burn fingers. I added an aftermarket cooler and all was well.
My present Mobo is a Gigabyte GA965P-DQ6. It runs quite cool, no problems inverted. I did turn the case upside down for a day to see any difference. I noticed that it ran about 4c cooler - not enough to matter.
It would, therefore, appear that different heatpipe design will react differently.
 
inverted design sucks IMO. I just switched my Antec P180 for a Lian Li V1200plusplus, etc

Temps went up 10*C idle 🙁

Went from 3.5 Ghz to 3 Ghz from 1.55v to 1.3v

Yes this is with proper cooling -- as much as the case will allow.

If you have put your rig together right, you wouldn't be having problems. I actually have the bigger Lian Li server case (see sig) and my mobo temps are COOLER than the non-inverted case I had the rig in. Yes, cooler. The previous case was a huge one as well, so it isn't the 'openness' of the case. Why is the rig as a whole cooler? Because the different temperature zones of the PC have been cordoned off in the inverted cases and ariflow in these regions is maximized. The PS is kept in the bottom with the hard drives with arflow comes across the HD's and is exhausted out the PS. Up in the motherboard "chamber", air is brought in from the window directed at exactly the hottest region(s) of the motherboard: chipset, vid card, CPU & ram. This air that is heated up by the components is then pulled out of the back of the case by another fan.

Again, if you put the rig together right and don't have a rat's nest of cables everywhere impeding ariflow then you should have, at the very least, the same temps as a non-inverted case.

Just my .02 and some have said it's not even worth half that. 🙂

exactly, a heat pipe will work just as well upside down.

no it actually wont be the same. mount any mb with heatpipes upside down and you'll notice immediate differences. i've done enough reading on google and on forums to know better than to mount a heatpipe mb upsidown. If asus says not to mount it upside down, i'm pretty sure you shouldn't

and yes this case will fit a tuniq tower, its wide as hell.
 
There's so much bad information in this thread, it's stunning.

And you checked temps in the morning at a room temp of 60F, and then finished getting it transplanted into the lian li in the afternoon when the room temp was around 75F? Seriously, you need to back up this kind of experience with some more numbers.

Not just, but way too many people just throw out their cpu/gpu temps on forums without giving the more important temperature along with it: ambient temperature before and after. Without that, all other temperatures are worthless numbers with no real meaning.
