I’m running an AMD Phenom in an AM2 socket motherboard. I want it to have a CPU and GPU block, the video card is a Nvidia Geforce 8800GT.
The temperatures have been very high in my case and I need a reliable and effective water cooling system to keep the temperatures down.
I’m looking to find a UV Light Filtration Unit that Can kill Legionairres in a heating system with high flow and Temperatures that are variable with a high temp limit of about 140 Degrees Fahrenheit. Thanks
Can you add a little salt to the drinking water for cows to keep it from freezing? Can it hurt the cows. Temperatures have been in the high 20′s to low 30′s at night and I would like to put maybe a tsp of salt in the water to see if I can keep it from freezing.
The cup of cold water would be inside a room. Since heat transfer flows from higher temperatures to colder, the water is gaining energy from different sources of higher temperatures. I know that an obvious answer is the Sun. What else though?
Thanks!

The other morning I noticed a large puddle of water coming out from under my washer. This puddle appeared after I heard a gurgling sound. Last night I was in the kitchen washing the dishes and was running the washer at the same time, when the wash cycle turned over to the rinse cycle and the water was draining from my washer, it began to bubble up out of my kitchen sink! And it was dirty water too…it looked like stuff was floating in it, like the pipes are dirty inside. Why did this happen? It happened again this morning, that when the wash cycle turns over into the rinse, and the rinse cycle turns over into spin cycle, the water bubbles up out of the kitchen sink. The laundry room is inside the bathroom, which is right next to the kitchen. I imagine all of the pipes are connected somehow. My husband thinks the drain leading from the washer is clogged and told me to pour Draino into it. I do not think that is the answer. Thanks for your help!
Good point about the cold weather. I live in the northeast, and we have had several consecutive days where the temperatures have been in the teens and twenties during the day, then in the single digits at night. Maybe that has something to do with it?
