Any advantage to mounting motherboard upside down?

[Rubycon]

I see this tray allows you to turn it 180.

Haven't seen it upside down - would there be any advantage to doing this thermal wise and for cable management purposes?

 

[Howard]

Mm... I think in most cases (no pun intended) the CPU HSF would have access to cooler air.

 

[Rubycon]

Well it was very easy to do! Flipped the tray around.

Yes of course.

EDIT: So far so good.

Have you noted any difference in thermal performance??

Not to point out the obvious, but heat rises...

 

[Rubycon]

No real change but seriously the 830 is like having a case with no doors or side panels since it's meshed. It has no profile for chimney effect and hot spots aren't really a problem. Now I have to say the X1900XTX is like a blast furnace and the cooler rejects all that heat outside so that really does help. Even if it should have letters spelling out the name of "Pratt and Whitney" on the cooling paddle.

LEDs on the RAM.? Must be a girl thing Nice set-up, don't let any rouge waves get to it.

I don't know what those (LED's) are for other than eye candy - I didn't put them on there and I guess it's ok. Looks like the system has some expensive as heck channel bank with the cover on when the lights are out.

There's 1000x more chance of a beer getting spilled on this thing than water from the pond.

Well, if your motherboard uses heatpipes for cooling, I would not recommend flipping the mobo upside down since this would make the heat rise to the chipset instead of taking heat from it.

Heat pipes work in a gravity free environment...like outer space dude. Links plz.
Heat pipes wick thier fluid back to the base.

EDIT: Plz read in total http://www.cheresources.com/htpipes.shtml

Some heat pipes don't have a wick and depend on gravity to pull the fluid back to the heat source. See "Grooved Tube"

Damn the man who invented flathead screws. :|

EDIT: So there's a wick in the grooves of a grooved heat pipe. I wish they'd made it clearer.

I've heard reports that A8N-SLI Premium boards overheat when in an inverted mobo case. One of my classmates has that problem and he has himself an old vid card cooler to cool the NB (he superglued it on).

 

[Rubycon]

Yes it has a heatpipe and this was considered. It was stress tested and did not seem to run any hotter at the blocks than normal.

They won't let me use the IR scanning image system to profile my system but it's amazing what a round of drinks will accomplish. :evil:

 

[GalvanizedYankee]

We need links...Lots of links.

You've read the one I linked above before Howard. Read it again

Well the system is on a ship that moves so the gravity is not static. Not that it would make a difference but then again what do I know?

EDIT: I have a program called burn bx that's supposed to be a chipset heating tool. I'll grab the Raytek and run this and pretend I'm in a Star Trek episode scanning for whatever.

Is the above a rhetorical question?? I think your as dumb as a fox.

What else could it be?

Oh and that thing is getting hot. The heatsink at the bottom is over 55C and climbing and it's a good 15C warmer than the southbridge which is actually north now. :laugh:

EDIT:

Ugh no sleep tonight. Btw what is the breach point of these heat pipes? I know the chips would probably be on the brink of phenolic ablation but seriously if the freon stuff in side goes really high will the seams give way and this thing explode?

 

[RallyMaster]

The heatpipes won't explode, but your SB certainly will

I have the old AMD HSF. I wonder how much power it can handle? This would be a great experiment to try with a 500W CO2 laser. :evil:

We have some fifth order fresnels over the stage that can collimate sunlight into a beam that will light a cigar instantly and make those mercury oven thermometers rupture (isn't that stuff still bad for you? ) so that should be interesting. Can't destroy it though because AMD needs it in case the chip dies.

 

[Howard]

I doubt there's enough fluid (mass-wise) for it to exert any dangerous pressures. If all of it evaporates, though, the heat pipe is pretty much useless.

 

[Rubycon]

I'm surprised the uber casericers haven't brazed a bourdon tube pressure gauge on the end of their heat pipes. With careful plotting it could probably serve as a crude form of aneroid thermometer.

Interesting idea, but how would you preserve the low-pressure environment?

I suppose a sign gasser would have the know-how to do this. (small manifold/make up tee and nipple, etc.) Obviously it would require a supply of the active agents used in the heat pipe too.
