| 214675 | 2004-02-11 10:31:00 | Hi Guys Got a portable chilly bin today. You might think 'so what', but this Bin is special. It has a freezing system in the lid, that runs off the cigarette lighter plug thing in cars. 12V. I wish to use this lid - when attached to me case - to cool my computer. I'm just wondering what I'd need to do to make this possible electric wise. How simple would it be and what would I need to do to make this freeze system to work from the computer power supply - not to be powered externally? The supplied wire has the end that plugs into the car electric port, is it a case of chopping that off and attaching one of those white 4 pin computer plugs to it and power it like that? Is the electricity supplied from the Computer Power Supply needed to be converted from AC to DC, or is it already DC when it reaches the motherboard? Any help in this would be appreciated. Rev Species 116 PS The reason for this is my CPU is hitting 60 degrees c, but has a recommended heatsink. |

| 214676 | 2004-02-11 10:51:00 | have a look here (www.overclockers.co.nz). these are the things that the chillibin uses. check out the forums for instructions on how best to set it up. have you checked what your case and room temps are?? |

| 214677 | 2004-02-11 11:01:00 | Thanks Tweak'e CPU at 57 System at 39 Room at sweltering levels ;) It is my room driving up the heat. but I don't need a room cooler, I need a computer cooler ;) I like the heat, my computer doesn't. I looked at the imediate link you gave, but there are no instructions on that particular page. Do I need to search a few links deep? Rev Species 116 |

| 214678 | 2004-02-11 11:14:00 | ask in the forum (http://forums.overclockers.co.nz/) 39 case temp is way to high unless your room temp is also very high. the temps should drop down to a resonable level if you can lower the case temp. |

| 214679 | 2004-02-11 15:43:00 | Hi Guys Found something useful to my plight :) : ----------------------------------- PC 12V Cigarette Lighter Panel - $25 The PC 12V Cigarette Lighter Panel comes pre-installed on a 5.25" silver faceplate, and plugs direct into your power supply. This handy device can also be used to power other items such as CD players, mobile phones and other accessories that use a 12V car cigarette plug. ----------------------------------- www.pccasegear.com.au Has a NZ branch too :) Rev Species 116 |

| 214680 | 2004-02-11 19:05:00 | What wattage is your PSU? Cause if its small it could cause problems, ie lack of power to other sources??? Please correct me if i am wrong. |

| 214682 | 2004-02-11 20:18:00 | I think you will find problems with the power supply not being able to handle the load. Either find a power supply that will handle the extra, or add another power supply just for chilliBin. The bins use a device called a "Peilter", and it does use a fairly high current. |

| 214683 | 2004-02-12 02:42:00 | Using a peltier device to cool the inside of your PC may not work quite as you expect. Due to thermal dynamics you room temp will need to be allot lower then your inside case temp. The biggist problem is the devices are designed to "draw" heat away and cannot produce a cool air flow in the way you need it. Best you could do is use a radiator system and re-cycle the air in the case. The other big danger is condensation build up!! My thought was to attach the device to one of the case pannels but you would still need to draw the heat onto the surface of the pannel. The other problem is they need ALOT of energy to work and you may end up needing a 400W plus PSU just to power the device!! |

| 214684 | 2004-02-12 03:13:00 | The Peltier effect is the reverse of the Seebeck (thermocouple) effect . A thermocouple produces a potential which depends on the termperature diffference between the hot and cold junctions . The Peltier device uses a current to produce a temperature difference between the sides . This can be up to 60°C difference, depending on the current, and the ability to remove heat fronm the hot side . A chilly bin cooler will need quite a high current . . . probably 8A or more . This might be a problem for a computer supply . You'll find that a heavy duty 12V supply will be quite costly . The other problem is that it's going to be a cobbled up system . You will have a smooth plate which gets cold, and a finned "hot" side with a fan to move the heat away . You might be able to fit a finned "heatsink" and fan to the cold side to get a stream of cold air to feed into the box . I think some cool air into the box might be a good idea . How about a board with a fitting to a 4" plastic hose to an inlet fan of the tower? That could be fitted at the bottom of a sash window . Or an airconditioner for the room . :D I've actually got a Peltier cooler for a computer: it's just the size of a CPU, with fins and a fan on the hot side, which plugs into a disk power socket . That works . But I think you'll get better results with a simpler, conventional approach . ;-) |
