Power supplies, North Bridges, Ram, Video Cards (if they are attached anyway), network cards, hard drives,anything that generates heat. Thats just the computers. Then you need to figure out what other equipment in the room that generates heat.
If this is a possible design for a server room then you need to think alot more professional than a car rad and AL blocks! Anything you use for a heat exchanger, be it s radiator or bong or whatever, will need to have cooled/heated air going through it to maintain a level of consistancy. You cannot cool/heat air without active cooling/heating. Active cooling being AC of somekind active heating a heater of somekind.
If this is for someone's business you need to find out all the variables of where this equipment will be installed. You will need to know how the piping will be routed, the amount of drop and rise the fluid will be traveling, the size of the piping, ect ect ect... It all starts with where the stuff will be installed. Then you take what you know there and start designing the system around that. Once you know how to route the piping and where all the equipment is going to go, then you need to calculate the heat dissapation of all the equipment that will be cooled. Once you find the total wattage of heat output of all the equipment then you can send that information to a company that designs heat exchangers. They will then make a custom exchanger to handle the load and they should give you the needed flow rate variables. Then from that you will have to figure out how to get that amount of flow through all of the attached water blocks on all of the equipment and through the exchanger where ever it will be installed. They should also give you an idea of how much active cooling/heating you will need to cool/heat the air that is going through the exchanger per ambient temp to maintain a safe level of operating temperature forthe equipment.
For example X is ambient air temp Y is the temperature that the air will need to be maintained for a consistant operatating temp, Z is the amount of cooling/heating needed to maintain Y.
If X is 100F then they will tell you that Z amount of cooling will be required to keep Y consistant. OR if X is -30F they will tell you how much HEATING will be required to keep Y consistant!
In something as expensive and important as a server room you want your operating temps to be within a certain range and consistancy. That is the only way to properly control things IMO. I would always want the temps of the cooled components to be consistant within a set limit. To cold and it can cause problems and to hot and it can cause problems. The heat exhanger will have to be retro fitted with some kind of electronic ciruitry that will turn on the AC or the heater to maintain the Liquids temperature to keep the components at the safe operating temperature. And of course this would all have to be approved by certified engineers in plumbing, electrical, and heating/cooling and then approved by the local building code people.
This is not going to be acheived by a car rad and aluminum blocks.
Now if you are just doing this in your house for a personal project then a car rad and AL blocks would probably be and option. But if you took this to a person in charge of a expensive sever room that is critical to be up 24/7 you will end up in the hospital getting the security gaurds boot from you a$$. Or at least you would in the USA.
So maybe explain in greater detail what it is you are thinking of doing with this project. Is it for a personal thing or someones business? And whatever the answer to that question is you then need to be a lot more spacific about the equipment being used (ALL of the equipment) and how it will be installed and in what enviroment (what kind of room, top floor/bottom floor, size of room ect. ect..).
Otherwise we are just wasting our time here.
