Sandwich water cooler system

I had ever o/c celeron 366 to 682 Mhz by using double peltiers water cooling system.The system was cooled enough to get ice at the cool plate.Could it ran more than this? that always the question in my mind.I though all the time to tweak this point.To push this system ran more than this it must be changed in some details.There were some points esp.used more peltiers,lower the water temperature,more power peltiers. more power water pump.In my home-made water jacket,it didn't have enough area for the thrid peltiers.So how could I increase peltiers? I add them in the rear side of slotket.You may think that isn't it work? Yehh it worked.. I had tried to add 30 mm peltier in the rear side of my 300 a that I had o/c it .It decreased temperature about 10-15 c.So I will try this concept to slotket too but I will used 4 peltiers,2 cool plates and 2 water jackets. And I will keep the water temperature as low as I can,use more water pump to optimize the results.

Installation

I used my home-made water jacket one in front and one for the rear side.I used 4 peltiers, one 90 watts and the other three rated 36 watts each.
I used two cool plates 80*80 mm that equaled to the two peltiers. For the water pump I used two small fish tank water pump rated 40 l/hr and 60 l/hr resprectively.Then held it together by nuts and screws. I had tested this system outside for searching the leakage.There were several points of leakage so I used liquid solder to solder it and checked it again. I had did it several time to make sure that no leakage was seen.then I put it to my system.The set up system was the same as the old tested. My mobo was Abit BX6-2,that I had reconstructed it already to measure internal diod temperture.I used micron pc 133 to made sure that ram wasn't the problem. My vga card was TNT2 m64 and I used another power supply rated 250 watts to make sure that there were enough power for four peltiers.A small water tank was used to reservior.and two pump to pump the water to each water jacket seperately.

Results

After installed it already,I started the water pump and peltiers first to got the system cool enough. I noticed there was ice on the cool plate within 5 min and the rear cool plate in about 9 min.The front got cooling faster than the rear mighted dued to the big pipe in the front side.This project gave me a lot of fun. The system was too cool so I looked in the MBM monitor to find out what was the temperature.With Asus slotket I could not seen the internal diod temperature so I look for the probe temperture. It decresed to zoro celcius and then stoped at this level although I could cool down the temperature of both cool plate to subzero.I didn't know why it didn't read.
After the system was cool enough I changed FSB to 133 MHz.It posted at 735 MHz.It could ran at that speed just a while before it locked up although I changed voltage setting to 2.5 .It still unstable.I had ran this system with my pentiumIII at FSB 133 MHz. before so the peripheral system mightn't be the problems.All of this causes might be due the cpu itself eg. the system wasn't cool enough,more voltage was need,or the chip itself couldn't ran at that level.
I had got the screen shot too but the picture was burr so I didn't put it in this page.Here is the close-up of the double water cooler system with ice around both cool plates.In this setting as you saw from the picture ,there were water drop around the water jacket .Condensation was my problem too. But I didn't insulated it yet because of I wanted to see what was going on around the cool plates. Condensation can short circuit and caused your system damage so If you want to try ,watch out! To prevent condensation ,I needed a closed system around this to prevent air contaction.That is my next task to do.Dued to my limited time to work in this workshop .I will changed my peltiers to two 90 watts peltiers.The results of putting another cooling system to the rear side,it worked .I can put the system far more than used one water cooler alone.But the results couldn't compared to the used of peltier in the rear side of celeron 300a becuse of in 300a the core in built in pcb but in slotket the cold should tranfer from the cool plate to spacer and to slotket pcb and pin to the cpu core.So less cold than expected .I will change some setting and will come back soon in sandwich water cooler part II
