It sounded like a brilliant idea, because with a small hole for the mouse and keyboard wires, (then seal up the open spaces or whatnot) you are running on super low temps with no risk of leaks, or noise at all. It also seems convenient, and possibly cheap? Can anyone confirm such a fridge's existence, or something similar? Posted by: Apokalipse perhaps you mean vapour phase change cooling? Posted by: Jeuk [QUOTE][i]Originally posted by Apokalipse [/i] [B]perhaps you mean vapour phase change cooling? [/B][/QUOTE] What did you call me? Posted by: cwiz vapor phase change cooling is what makes a refrigerator cold. it is used in electronics by making putting the part that getts really cold directly on the cpu... u need to use gell to keep condensation from shorting the mobo. i'll talk more about this later Posted by: Jeuk [QUOTE][i]Originally posted by cwiz [/i] [B]vapor phase change cooling is what makes a refrigerator cold. it is used in electronics by making putting the part that getts really cold directly on the cpu... u need to use gell to keep condensation from shorting the mobo. i'll talk more about this later [/B][/QUOTE] How much does an efficient, decent system of these things cost, and considering I've never even installed a simple water cooling structure, would I ever be able to install this one? Posted by: CrazeD Around 1000$. Posted by: aspire.comptech you can get a custom built phase unit for about 400-500, aor find a used one for between 300 and 400 No point buying a low performance Asetek one... Posted by: Apokalipse [QUOTE][i]Originally posted by Jeuk [/i] [B]What did you call me? [/B][/QUOTE]?? err, I didn't call you anything.. anyway, you can get Asetek Vapochill ones, but they're not the best. Posted by: Evergreen Are phase change systems directly on the die, or is a block used? Posted by: Jeuk Are they really very super difficult to install, and if I make a mistake will everything explode? Posted by: cwiz basically you have a cold plate, which is like an inclosed heat sink. a tube of warm/hot high pressure liquid refrigerant runs to the cpu, a nozzle releases the refigerant to low pressure making it turn into a low temp vapor when it hits the hot heatsink/coldplate. the gas is run thru a condenser that is basically like a radiator for a water cooling system. from that point it is recompressed by a pump becoming a warm high pressure liquid again. depending on the refrigerant and pressures, you will achieve different cooling temps. this process is known as a phase change cooling system, specifically a vapor compression refrigeration system. it is exactly how ~95% of refrigerators and air conditioners work, the refrigerant is just released to low pressure in different ways for each application.

[/B][/QUOTE] The system is complex to say the least, but can installation be done by someone with experience only in putting together common computer hardware (heatsinks, cpus, GPUs, harddrives, etc)? Furthermore, how much of a performance boost can one achieve out of this? I remember seeing an insane video where liquid nitrogen was used to cool a slow cpu which was eventually over clocked like 10 times its max. Since you guys are listing temperature in the negatives is it possible to double an already extremely fast CPU (Pentium 4 extreme edition for example)? Thanks for all the knowledge, guys :) Posted by: cwiz u can get a core 2 cpu/mobo/ram for less than a decent phase change system. i'm not really sure how they get their cpu's to go that high... i think its more than just cooling and messing with the bios u could probably install it if you've built a few computers. i've never done it, so dont take my word for it. u need insulating gell to keep condensation from shorting the board. have you looked into water cooling w/ TEC pads? they are really effective [url]http://www.petrastechshop.com/tecmop.html[/url] u gotta have a good w/c loop to use these though. it goes cpu\thermalpaste\coldplate\TEC(Peltier)\wc block w pump and radiator. u can put one on your cpu (200W+), one on the northbridge (prob 80W), one on the gpu (200W+) and get some w/c sleeves for your ram and HDD's. all for (probably) less than a phase change for you cpu Posted by: joshd [QUOTE][i]Originally posted by cwiz [/i] [B]have you looked into water cooling w/ TEC pads? they are really effective [url]http://www.petrastechshop.com/tecmop.html[/url] u gotta have a good w/c loop to use these though. it goes cpu\thermalpaste\coldplate\TEC(Peltier)\wc block w pump and radiator. u can put one on your cpu (200W+), one on the northbridge (prob 80W), one on the gpu (200W+) and get some w/c sleeves for your ram and HDD's. all for (probably) less than a phase change for you cpu [/B][/QUOTE] decent TEC cooling also needs the mobo to be covered in some form of insulation, to stop the air getting to it. idle temps with decent TECs are often sub-zero, so condensation becomes an issue. you also need a PSU with a good 50A on the 12v rail to power the more powerful TECs. these cost alot... i wouldnt bother with phase change unless OCing is a major hobby of yours. it isnt really any good for 24/7 useage, because the power consumption is also very high, they are loud, and if the insulation on the mobo somehow breaks without you noticing, bye bye motherboard. ambient air hitting a surface at a good -50*C means mucho condensation...

[/B][/QUOTE] So your saying that unless I am some kind of OCD cooling freak that drives CPUs to the lowest temperature as some insane science expirement, one of these would do: [url]http://www.newegg.com/Product/Product.asp?item=N82E16835124007[/url] ?? They seem easy enough to install, minus the whole making a hole in the chassis. I guess my general question is, will the liquid cooling have a significant potential to increase speed, even with an already very fast computer like a Pentium 4 Quad core or something? Posted by: Apokalipse there are no quad core pentium 4's. anyway, I would just recommend a descent watercooling kit for you. a kit won't be too hard to install, but still offer good cooling.

[/B][/QUOTE] yea, build a decent kit, dont buy some pre-made rubbish. I'd say look to spend a good $2-300 on it, or it won't be any better than air cooling.

[/B][/QUOTE] Yeah, my bad, I meant these: [url]http://www.newegg.com/Product/Product.asp?Item=N82E16819115011[/url] Just a tendency to name everything intel pentium :o Thanks for all the help, I guess a simple kit will have to do. Posted by: joshd your better off with a decent air cooler, to be honest, than the cheap watercooling kits. Posted by: Jeuk [QUOTE][i]Originally posted by joshd [/i] [B]your better off with a decent air cooler, to be honest, than the cheap watercooling kits. [/B][/QUOTE] I'll get a decent water cooling system, if you guys can recommend some. It's not just the cooling that's important to me, but I rather like silence :) Posted by: joshd for decent WC, you need to build your own system by buying pump, blocks, radiator(s), tubing separatly, and putting it together, leak testing for a while, then installing it in your PC. if you are indeed cooling a QX6700, you will need a very good block with triple radiator, with 3x 120mm fans mounted to that. WC isnt as quiet as people think. Posted by: aspire.comptech [url]http://www.petrastechshop.com/pecoel.html[/url] I would reccomend this if you wanted to quietly cool your qx6700 vBulletin Copyright ©2000 - 2003, Jelsoft Enterprises Limited.
