Ok, friend is telling me it helped lower his temps. He use a plastic box thing for his reservoir. But his put his radiator inside the box. Theres about a gallon of water inside the box. Would that be better or help by putting the radiator in the water? Iv seen people do similiar things before.
i know, the water would take the heat from the radiator. Theres enough water in the box, that it wouldnt raise cpu temps.

He ran his tubes to the radiator, then put the radiator under the water in his reservoir.Kind of makes sense, that the amount of water would help dissipate water from the radiator.

Anyone else do this or elaborate why this would or wouldnt work.
 
Once built a system similar to this. Using an old glass 10-gallon fish tank for the reservoir gives the best results. A 1-gallon reservoir is too small for the smallest rad to make a difference.

Now, if the 1-gallon "glass" reservoir was in the loop and the rad in a normal location with fan, then the temps should lower more. Vlassic or Mt. Olive glass 1-gallon pickle jars work great for something like this. MorrisGS does F@H with the jar outside his bedroom window with the lines running to it. this time of year his temps are really low.
 
You are effectively making the "reservoir" your new heat-sink by dunking the radiator in it. It will work great for short runs but eventually you will heat all of the water up until it finds balance with the heat load. For intermittent loads you can do lots with a big res because your system has lots of thermal mass. If your load is steady for hours or days then all that matters is how much heat you can dissipate.
 
Yeah, well my setup now. I have 2 radiators. I have 1 120mm and 1 dual 120mm radiator. I am using a 1 gallon jug for my reservoir. i figured that would be better then using one of those reservoirs that only hold a really small amount. Iwas tempted to do it myself. But if its not going to make a difference. I'll just leave it a lone.

thx for the help
