I was sitting here and cameup with a good idea. I have a small refrigerator that i never use. I cut 2 80mm in it and then ran piping from one hole to my intake fans and then piping to the blowing fans. I tured the temp down as low as it could go and now my case is about 12 degrees cooler. Just thought i'de share.

Cool! I might try that. My system seems to really get hot when I run graphically intense games! Hope your idea isn't copyrighted ;)

This idea is so BIZARRE it is cool. How about a dorm size fridge and sticking the whole cpu box inside. I like it. No more fan noise, cpu temp cold, store beer with your computer! Thanx RYAN, made me think. Drill a few holes for I/O and done.

BAD IDEA! While this will push some colder air onto your components, you can't control condensation buildup, and risk shorting/killing system components. (Leave and refrigerator door open for a while and watch all the condensation that develops. Do you relly want all that moisture going into youe electrical components?)

A few more notes: I have the refrigerator setu p so that the air has to circulate in the frige befor it can return to the system. Otherwise it would just go strat through the fridge and not get cooled. I also have several fans mounted along the pipes leading to and from the fridge to keep the air moving. About condensation, i have a clocth over the out-put pipe so dust and water are stopped. Also since it is a closed circut the is no way for mostier to get in. PS i live in Arizona so there is no humidity.

"PS i live in Arizona so there is no humidity." While a relatively low humidity environment (like in AZ) may help to decrease the likelihood of condensation, there is no such thing as "no humidity," and the risk of condensation remains a real threat. (current humidity in PHX at the time of this post is 36%) 1. Warm air contains at least some moisture (water vapor) 2. Water vapor molecules combined with cold causes the vapor to liquify. (condensation) To see if condensation really exists where you live, set out a botle of cold beer in a warm room. Let it sit for 1/2 hour and see if water develops on the outside of the bottle. ANY moisture is bad, especially considering the constant stream of cold air from your refrigerator + the heat inside your case would probably produce a more extreme result, especially after prolonged use. As far as your system being a "closed circuit," I have to disagree as well. If there is ANY airflow in or out of your case, it is NOT closed circuit, and moisture CAN get in. (Think open card clots on the back of your case, power supply fan and case fans) If you're that hell bent on cooling, even a cheap water cooling system would be a better solution. (Compare the price of a cheap water cooling rig to the price of a refrigerator, fans, piping and all the work necessary to theoretically make this work) I wasn't a science major in college, but I know enough to avoid this type setup...

UTLLAMA is right. Condensation could form on your system. The dry climate helps, but if the temperature of the air is 80 Deg F with 36% Relative humidity, condensation can form when the dew point temperature of approximately 50 Deg F or below is reached. So if the air is coming out of your refrigerator at 45 deg F the components near this inlet are very much at risk of moisture damage. If the temperature or relative humidity are higher the dew point is even higher. 90 deg with 36%RH will condense at approx 60 deg. 80 deg with 50% RH will also condense at approx 60 deg. So your system is at risk. Computers actually like RH of about 60% this keeps the static electricity from developing, but by driving the temperature down as far as you are you are driving the relative humidity up.
