Ask not for whom the bell tolls. It tolls for me... Bong! Bong! Bong! Setup a Dual Bong Cooler in my mega-loop. For those not familiar with my WCing system...check out this thread: Yes, Another Car Radiator Thread....Major 56K Warning! Nothing new in the Bong Cooler--idea has been around a long time and done by many others. So far I am averaging res temps that are 3.3-7C (6-12F) below ambient. I've had this bong cooler setup for a couple of weeks now. However, I started it in a tub and moved it into a permanent setup today. My current cooling setup is as follows: Res> Pump> Manifold> 3 PCs> Manifold> Stacked Dual Car Rads> Bong Coolers> Res Each PC is a single loop--Cpu, Nb: 1-1xGpu, 2-2xGpu Here's the pix--apologies in advance for the quality of some of them: That's the big picture. 1/2 of the cooler top is not on in that pic. The housing for the stacked dual car rads and fans can be seen in the background. Res with the top on completely. I knew that I was going to want/need to look/check/get in there periodically....so I cut the top in half! Anything else would have required me to shut down the rigs and cooling system, and remove the bongs just to get a peek inside. Worked out pretty good. Cheapo $26 cooler from wally-world.
