Inverted Heat Pipes

Okay, so I ordered an Asus A8N-SLI Premium mobo to go in my Lian Li PC-V1000. I've heard a lot of comments about heat pipes and haven't been able to get any word from Lian Li. Their tech support doesn't seem to work (or least least not with firefox). While looking at alternative coolers I shot this email to Thermalright:

How well does your VGA cooler work when mounted in inverted cases like Lian Li's?

And got this back:

Hi,

Not well.

For Thermalright.

So... With all these comments spread about this forum about how mobo owners shouldn't worry about heatpipes in inverted cases I'm confused. Does anyone actually have any numbers to support this either way?
 
If heatpipes are inverted, the liquid that's supposed to evaporate and carry the heat up sits at the wrong end of the sink, far away from the hot point on the processor. In turn not absorbing heat. You're going to get significantly worse cooling capabilities with it inverted.
 
Don’t do it!

I read about the problems but insisted on trying it myself. The chipset cooler/heatpipe gets so hot you can literally burn yourself on it. Flipping the case upside down (with the motherboard right side up) reduced the temperatures drastically! On a side note, it’s possible to transfer heat downwards using wicked heatpipes. Unfortunately, Asus uses evaporative heatpipes.
 
I have myself quite a quandry then. I guess I'll be looking for a new case. Damn Lian Li, I wanted to stick with them.
 
depends whether they are wicked or not

Me confused.
Your going to get a new case because a 'heat pipe' type video cooler wont work inverted :confused:
 
Motherboard heatpipe. I was talking about VGA coolers because they got back to me first.

Now I got this:
Dear Sir,

The motherboard cannot be mounted upside down if it has the heatpipe. Doing so will cause the system to overheat. Thank you!

Sincerely,

ASUS Support Team

I'm going to try and return the mobo to Newegg. I'll need to pick a different mobo. Suggestions? Need a good reliable board, don't really need SLI. Athlon 64 with ability to upgrade to X2 or FX. I could just downgrade a notch to the A8N-SLI Deluxe instead of the Premium.
 
OK, I got you now.
And yes, you are right, you do not want to run A8N Premium inverted.
Check out the DFI boards
Water cooling the board would be the [H] thing to do :)
 
Same PC, tested back to back

Coolermaster Wavemaster (not inverted)
CPU: 35c
MOBO: 29c

Lian Li V1200 (Inverted heatpipe)
CPU: 37c
MOBO: 39c
