kaya Posted May 26, 2008 Share Posted May 26, 2008 Hello, I was just trying to find a cheap way to cool the water down, and saw these I am just thinking outloud here so please bear with me http://www.newegg.com/Product/Product.aspx...N82E16835108063 would these work as a chiller, or not?

dsoz Posted May 26, 2008 Share Posted May 26, 2008 How would you use it? To me it looks like that is a water pump for use inside a computer. THe water would act like coolant in your car. I don't think that there would be enough cooling from it to act like a chiller. I could be wrong. dsoz Link to comment
Rocket Posted May 26, 2008 Share Posted May 26, 2008 I have water cooling on my computer. How it works is water acts like a radiatior and carries the heat away from the heat source and moves it to a "radiator" that passes thoough tiny fins for more surface area contact. It works quite well. BUT!!! It cannot cool the tank down past ambient. You would need an actually refrigerant to get cooling. So if your house is kept at 75F or below, it could work nicely. Otherwise... Link to comment
krankykris Posted May 26, 2008 Share Posted May 26, 2008 sounds like a terrible idea to me. they're not rated for saltwater or for the volumes that a saltwater tank would need. a water cooling system for a PC is designed to cool very warm fluid to slightly less warm fluid with radiators and etc. there is no condenser for it like a saltwater chiller. not to mention some of them are built with copper pipes and that would spell doom for you tank. just cooler vs chiller should tip you off. spend a little extra $ on your tank and get a chiller proper.

bamackc Posted May 26, 2008 Share Posted May 26, 2008 placing a fan blowin across the "radiator" whould also incress heat transfer i might work set it up and tell us whatt happens Link to comment
wmo168 Posted May 26, 2008 Share Posted May 26, 2008 You should buy an ice probe and install it like mine http://www.nano-reef.com/forums/index.php?showtopic=158556 Link to comment
evilc66 Posted May 26, 2008 Share Posted May 26, 2008 All commercial PC watercooling kits contain metals that will be in direct contact with the water you are trying to cool. This will spell disaster as most of them contain copper alloys. You would be suprised as to how well evaporation works as a cooling medium Link to comment
strapingyunglad Posted May 26, 2008 Share Posted May 26, 2008 Ive got problems with heating in my tank, so are you saying that if I remove my glass lid the heat could decrease? Link to comment
BruiseAndy Posted May 27, 2008 Share Posted May 27, 2008 Ive got problems with heating in my tank, so are you saying that if I remove my glass lid the heat could decrease? Yes, get a fan blowing across the surface of the water and it will decrease even more. Link to comment
Daemonfly Posted May 27, 2008 Share Posted May 27, 2008 Mostly great responses. It's been discussed many times already, and always shown it won't work. Why? All PC water cooling systems use either aluminum (old or cheap ones) or the better copper, both of which would be problematic in our systems. You'd have to use non-problematic metals, like high quality stainless or titanium, but then these don't have very good heat transfer qualities, so it's not worth the cost. Ive got problems with heating in my tank, so are you saying that if I remove my glass lid the heat could decrease? Most likely, but this depends on if you have a full hood or not, and how it's all set up. A properly cooled fully enclosed hood WITH glass lid on tank can actually run cooler, and have way less evap. than a tank with no lid. Link to comment
The Propagator Posted May 31, 2008 Share Posted May 31, 2008 I have no idea why no one has pushed Pelteir coolers on this website given the number of small tanks we have here. A couple good size peltiers would cool down a nano easily I would think. Making the block would be a PITA though. Link to comment
eklikewhoa Posted May 31, 2008 Share Posted May 31, 2008 I have not had any problems with a simple fan cooling the tank....My new tank would reach 90f+ with all the lights on but now is a stable 79f with a few pc fans and the RK2 to keep it super stable. Link to comment
The Propagator Posted May 31, 2008 Share Posted May 31, 2008 For most that will work but some homes are in areas where the ambient temp alone makes AC a must or the tank will cook quite fast with just fans and no chiller. Take LA for example the air is so humid and hot during the summer time that with out AC or a chiller you will cook your tank pretty fast. I think most folks who are asking about a chiller either have no AC or live in a dorm, or may be trying to lessen the burden on their parents by choice or by force and trying to find out the cheapest way to do it. Which in my personal opinion a couple large pelteirs would do it. I am almost positive thats all an Ice probe chiller is. A Pelteir with a probe. Link to comment

Do a google search, it has been done before with great effect. I don't remember where,but someone on the net gave complete instructions on how to make one. If I had any skill in that department I would have made one myself. Good luck! Link to comment
yardboy Posted May 31, 2008 Share Posted May 31, 2008 What's shown is a Peltier cooler, since in the reviews it's stated that it takes 50W of power and cools the processor down to 33 degrees. As Prop says, an IceProbe is a Peltier (the "probe" is the block used for heat transfer) Nano-Tuners had some for sale some time ago with coolers that looked very much like the one shown, but I looked and they don't offer them any more, don't know if there's a problem with them or not. Titanium may not have as high of a heat transfer coefficent as copper but it's good enough for a cooler, it's what all chillers are or should be using. Industrial condensers switched to titanium long ago, with only a 15% increase in size to make up for the lower coefficient. Bottom line is, find out what the heat transfer metal in that cooler is, and if it's titanium or stainless, it could work. Contact Nano-Tuners to find out why they quit carrying them and let that be your guide. Good luck. DIY RULES!!!!! Link to comment
The Propagator Posted June 2, 2008 Share Posted June 2, 2008 http://cgi.ebay.com/Gigantic-62mm-545-Watt...1QQcmdZViewItem 545w Pelteirs for $21.00 each and they are potted ! I think I am gonna buy a couple some time and try them out. Link to comment
BKtomodachi Posted June 2, 2008 Share Posted June 2, 2008 545 watts? Uh... AFAIK the whole tank I'm planning uses less than this combined when every single piece of equipment is turned on. Are you sure thats right? Link to comment
The Propagator Posted June 3, 2008 Share Posted June 3, 2008 Yes thats correct ( by their auction text any ways ). Chillers that are capable of any kind of pull down worth noticing do draw a lot of voltage and or amperage. Link to comment
filefish949 Posted June 3, 2008 Share Posted June 3, 2008 To convert a horse power rating (HP) to Watts (W) simply multiply the horsepower rating by 746 HP x 746 = W just get a chiller, they are tried and true, there are plenty of other things to DIY in your tank i know they are a bunch of money but if you buy a 1/10 chiller used for $300, years from now you will sell it for $300, if you spent $150 on a DIY project, years from now you will get nothing for it Link to comment
The Propagator Posted June 3, 2008 Share Posted June 3, 2008 No way. You'd be lucky to get $200.00 for 2-3 year old 1/10th chiller. Ebay is the only place you would even stand a chance and then you would have to do a buy it now and hope for a sucker. But your right you cant get much in selling your projects but thats the Idea any way. You don't put much in them to begin with ( or you wouldn't have chosen a DIY project to begin with right ) On the other hand, I see window conversion chillers selling on Ebay all the time for $200-$250, and new 1/10th HP chillers going for $300.00 - $330. I certainly wouldn't pay you $300.00 for a couple year pld chiller when I could buy it brand new for $30.00 more though. Hell you can get a CL85 for under well $200 for up to a 12 gal tank and up to 7 deg pull down. Link to comment
RedTurq Posted June 24, 2008 Share Posted June 24, 2008 Why not just put this near your tank. http://www.youtube.com/watch?v=zR9CA8lJGvs Just connect the fan to a temp controller or just run the fan all day and have the heater regulate the temp. Either way you are using same amount of wattage more or less. Link to comment
