okay i have this mobo and i was wondering if there is anything besides air inside those heat pipes? are they solid? or hollow? i have some conserns about my plans and the heat generated by them here are the specs from newegg.com thanks for the help
............................ what? im as lost as i was when i started this thread what kind of gas? would it be a bad thing to cut them? is the liquid a condensed form of the gas? or what i need more details then that. thanks for the replys tho
there is, im not kidding, water in them, the pipe is under a vacuum so the water is in gas form at normal temperatures, you "could" propably cut them open and mod them to work as water coolers, havent tried yet though
don't remember where i saw it I think it was here or xtremesystems, but inside is liquid and what appears to be rystal granules that line the wall of the heat pipe and act as the thermal wick.
Heat pipes contain a very small amount of liquid in them. Unlike what most people think, the heat pipes do not contain any air. The liquid is put inside the tube under a vacuum. To allow for the vapor to return from point A to Point B after heat is applied the heat pipe uses a wick structure (either mesh, slinters, foam, extrusions, etc) to return the evaporated liquid. Most PC heat pipes use de-ionized water or some similar chemical. If you really want to know more about heat pipes I recommend you read this book: http://www.amazon.com/Heat-Pipes-Fifth-Theory-Applications/dp/0750667540 If you want to get custom heat pipes you can buy them here: http://www.enertron-inc.com/heatpipe.asp And yes, I have bought heat pipes from them for an ISEF competition project in my Sophomore year. edit: Been there done that (was my ISEF project coincidentally lol), and it works quite well depending on how you design it. However, you can't cut them and use it. Won't work as you can't get a vacuum again. edit2: Sorry to hijack the thread, but any one here know where to buy plate like heat pipes like those used on laptops?
Some heatpipes do have air in, there will never be a vacuum inside though as some or all of the operating fluid will be in it's vapour phase. The pressure is reduced so that the water boils at around the operating temperature of the components to be cooled, the water vapour then travels through the heat pipe to the cool end (or coolest point in a multidrop system) where in recondenses. The energy absorbed from the components in boiling the water is transferred to the fins at the cool point when the water recondenses. The water then travels back to the hot point and the cycle continues. The wick is incorporated to move the water back to the hot point even if it's above the cold point. For heat pipes that are operating at extreme temperatures the water may be replaced with a different liquid. The flat heatpipes used in laptops are called planar heatpipes, you might find a manufacturer if you google that term. Moriquendi
okay well the reason why i ask is because i have some heat pipes that are covering the MOFSETs on my mobo and they are tied into the North Bridge and South Bridge block. i dont want them to be i want to remove the NB & SB from the loop and take care of them seperately the MOFSETs will have small fans blowing on them from start-up to shut-down so im not worried bout that at all what i am worried about is cutting the pipes and ruining the cooling power of them any suggestions?
i have a link at the top of the page of my mobo so you guys think that i shouldnt cut the heat pipes to use the current heatsinks that are supplied?
Correct. Cutting the heat pipes will destroy efficiency of the heatsink. As for watercooling the NB, take a look at the MCW30: http://www.swiftnets.com/products/mcw30.asp If you haven't done WCing before: http://www.overclockerstech.com/water-cooling-guide-for-beginners/
ive been thinking about seperating the MOFSETs from the NB & SB block and as you can see they are kinda connected with heat pipes
A normal-sized heatpipe using water as the medium has an internal pressure of 0.1-0.15 bar. That kind of vacuum can be easily made at home with a simple pump or a syringe. The hard part is sealing the end of the pipe.
