Ok, but how are you planning to cool the hot side of the TEC?....I think u need to find out how a TEC works.
You need to keep the hotside of a TEC as cool as possible, to get the Cold side as cold as possible.
If you want to cool the rad with the cold side, what will keep the hot side cool?

That's how the coolit modules work. The large heatsink in all of the modules are connected to the hot-side of the tec module, to cool it down.

sry, it took so long to get back on this, I really appreciate the input. nobody I know deals with TECs so I don't have much outside input into getting something going with em.
I've never seen any of the coolit TEC models 1st hand, only the promo pics that r available. and w/ the shield thats mounted on them, its difficult to tell just where the TECs r mounted. Since I have 1 of their entry level models into w/c'ng (Vantage) I was thinking of ways to upgrade it to something closer to a Freezone or Eliminator. or if that was even possible? idk.
I took a quick preview of the link u left for me, I'm heading back there now for info and ideas... thx thumb.gif

I have been debating back and forth for about a month now as to whether or not I want to use or sell a brand new FreeZone Elite Version 2 with MTEC and latest firmware and software plus mounts that will work with 1155 sockets and 2011. I would use it on either a V Extreme 3770K or an X79 Pro 3930K. I have been friends with a number of folks up in Calgary and they have provided me with all kinds of great deals. When they found out what I did for all the Dell XPS 700 customers, world-wide, and knew that I never asked for anything, they felt like they wanted to help me out. Great people there. I have had a number of Boreas coolers, and right now I am down to the New Freezone and two New Vantages. Anyone have any opinion as to why I should use or sell the Freezone Elite. In my thinking they are "priceless" when new as they will not be made again. Basically the issue with this product was that the cost to make the product pushed it out of most people's reach and the profit margin was just too low. I never had an issue with any product that CoolitSystems has made and they are for all practical purposes the Corsair products, without their name. Use or Sell is the question. I am not overclocking like I once was and am more video,photography, graphics focused and I often think someone else should benefit from the speed this unit will provide. I have never found anything like them, but to hold onto it just because it is a "Classic" doesn't make sense. Thanks for your input!!

I'm interested in this. So please don't kill me xD

Is TEC like Watercooling? What are the difference and how hard is it to maintain and do maintenance?

Thanks!

Hey it is nice to see a few "diehards" dropping in here. Speaking of Rads, does anyone know what happens to the flow through the radiator on an H100 if one of the screws goes too far through the support hole and pushes into the fins below. Does flow get restricted if fins are bent? I don't know if anyone here has ever noticed but Corsair would be smart to change their install design. When screws are going into the mounts on the radiator it makes no sense to have fins below those screw holes unless there is a solid plate that won't allow the screw to penetrate any deeper than the plate. I have found that occassionally a screw can get stripped as it isn't able to hold the weight of a push pull set up and in driving the screw deeper I discovered what the outcome can be. I am having it replaced by Amazon. This is my 3rd one of these and this hasn't happened before but now that it did, I am saying to myself, "What a stupid design. Corsair is asking for a potential problem". Appreciate any feedback. Maybe a bent fin doesn't matter at all but if enough are bent or if the damage was significant couldn't you spring a leak? I have never looked into the actual flow design of radiators and thought I would ask before I go off researching. Thanks all!

Who is out to kill you! XD? Direct water cooler simply passes water through a small heat sink that absorbs the heat and carries it away to a radiator which has many fins that are very thin. the hot water flows through the fins and fans blow room temp air over the fins and the water's heat is given up to the cooler outside air and blown into your room. One of the advantages is that the heat from the cpu is absorbed by water and carried through a closed tube to the radiator rather than being dissipated thoughout the inside of your case, and raising your case temp. It is a cycle that is self defeating in a sense. The problem with water cooling and room ambient temperature is that you can only cool the water as low as the room temp is and that is hard to acchieve unless you have a beast of a radiator and amazing fans. Your other option with water cooling would be to run an air conditioner in your room that the PC is in and lower the room temp so low that the air blowing over the radiator would lower the water temp in the hose to a much lower level. That means a big electric bill and you are cooling the whole room just for a 2X2 inch cpu. So instead you set up a "kiind of AC system" that uses energy (electricity) but on a smaller scale and what this kind of unit does is it uses electrical current to set up a seperation of heat and less heat across two metals. The one heats up but the other drops in temp and it is that which is coming into contact with the warm water coming from your cpu. So you go lower than room temp and thus lower the cpu temp even more which allows for greater overclocking as the heat is no longer a bottle neck in the increased speed of your cpu. It requires energy. Just like an air conditioner or a fridge. A fridge is not making cold air. It is removing the hot air. Ever feel the heat coming away from your fridge. What is left inside is colder because the heat was taken out. Stand outside of an airconditioner and you will feel very hot air that is being removed from the room and the cold air is left to be blown back in. A down side to a unit that overpowers ambient room temp is humidity. If there is humidity in the case, as you lower air temp there is less space between air molecules to hold water vapor so it is forced out of the air and it condenses on your heatsink and if it is significant it can drop water onto computer parts and short them out. Look up dew point if you want to understand that concept. Hope this helps.

I forgot to add that a good unit like the Freezone Elite is a closed system and well built. There is no maintainence. You set it up and make you selected temp choices and it is over. Provided that you don't get a bad pump, they ususally can go 7 or more years without any significant evaporation. Unlike a water set up that you build yourself, you have to do a bit more more work. Something like the Corsair H100 is a self contained no maintainence system but it doesn't have the ability to cool the water beyond room temp. But room temp is usually sufficent and low enough to allow for overclocking. If you really want to spend the cash, you move into the liquid gas category where you are dropping your temps to temps that would kill you if you were exposed to outside air temps of the same ridiculous drops. I spent two weeks at Mount Everest Base Camp and temps would drop from 70 F during the day to 50 below at night. Would have made for great ambient room temps and regular liquid cooling except that the water would have froze, just like I was!! A gas like Nitrogen becomes a liquid at some 300 degrees below zero so it isn't going to destroy your parts!! For fun, fill a granade with water and seal it and put it in your freezer. Keep the family outside because when that water freezes, it mysteriously expands right before it freezes and the pressure cannot be stopped and go to Sears and get a new Kenmore!! All things become more dense as they cool as the molecules are slowing down and the attractive forces between them is not overpowered by the movement generated by heat. Water continues to get more and more dense but when it goes below 34 it begins to expand and when it freezes it takes up more not less space. It is that very poorly understood "miracle" that keeps lakes from freezing from top to bottom for if that happened all life on earth would end!!

Wow...lots of reading here, LOL.

Anyway, theoretically you are able to get the liquid cooled down under room temp with a Coolit TEC chiller, but it's not gonna happen when being used to cool a CPU.
Where water-cooling uses a radiator to get the water temp down, a Freezone or a Boreas chills the warmed up water by using the TECs. But if you do not keep the hot side of the TECs as cold as possible, the cold side won't get colder so it can not chill down the water which will result that the water temp keeps rising
The Boreas and Freezone both have a large heatsink attached to the hot side of the TEC, if you are able to keep that as cols as possible, then the cold side will be able to get the liquid sub ambient temps.
I had 2 freezones in series on a MCP350 with a custom cpu block. With 2x 3000rpm fans I was able to get awesome temps (with condensation n the tec-blocks and cpu-block. On load my 1090T was able to stay under 30C. But the noise was unbearable, like a jet was taking of. Last winter I positioned my pc outside with -10C, my coolant wasn't even measurable, LOL (0was minimum), but I kept my cpu under 20C.
I sure could keep the 2 units at full speed and the fans on their max I would get sub-ambient temps, but my power consumption would go up too..$$$$$$.

Now I have installed a 360 and a 240 rad, with fans on low/med setting. Maybe I'll hook them up with my current setup dunno about that yet. Or maybe I'll just sell them and get a Chiller (not a TEC, but a gas-based chiller smile.gif.

Xeno, Do you know if any folks are still using the CoolIT products like the Freezone Elite? I posted long ago I never did make a decision about whether or not to use my Freezone Elite V2. I do know that by exchanging fans and using a top mount with additional strategically placed fans, all the TEC heat is exhausted out of the case before it has a chance to radiate away from the unit. The right fans eliminate the noise. Have you followed this topic any further? Thanks GB

I have no idea how many people are still using the units. I still own them, but they're sitting in a box doing nothing. I do have an idea to put them into a Lian-Li PC V350, and hook them up to my loop, creating a switch to use either the rads or the 2 units. They still are awesome units to use, I just can't sell them XD.
