Started out by adding a second radiator to my stock Thermaltake 735 system. I modified the top PSU bay by enclosing it with plexiglass. Cut a hole in top for second radiator, then mounted radiator and 120mmAerocool fan inside psu bay. Mounted two 80mm fan on the back for added air flow. With just the 120mm, I’m moving about 60cfm. When the two 80mm are turned on, it pushes an extra 48cfm through the radiator totaling 108cfm. This is in addition to the stock Thermaltake radiator mounted on the back of the case. The stock radiator is also running a Aerocool extreme120mm (89cfm). The second radiator has lowered my temps 5 to 6 degrees. The full system runs through Two Thermaltake Auqabay M4 HDD coolers, CPU, VGA, and NB chip coolers. HDD, CPU, and VGA all have thermal probes and are controlled by the Coolermaster Aerogate 3. All fans are also controlled by the Aerogate. With such a big case (Coolermaster Stacker) four UV cathodes were used along with two white cathodes (these are used just to light the case if I need to work on it. No more flashlights in the mouth while adjusting wires) and four blue lazer led’s for the front of the case. (These respond the the HDD activity). All lights are controlled by Sunbeam’s lightbus giving me the capability to control each light in four different ways. Water Temp is read by Thermaltake’s T-probe. I Dremeled a hole for the display in one of the removable front plates and clicked it in place. One other thing that I found really cool was this sticky foam padding (2 - 3 mm thick) that I used on the floor of the case and also around the top PSU bay. This stuff works great It dampens sound and also sealed all the small cracks in the top PSU bay giving me an air tight compartment for the airflow to my top radiator.You can get this stuff at WalMart in the craft dept. or at any craft store. Just peel and stick.
