My bad. My use of 'convenction' would be what you call passive cooling (natural convection). If the fluid is mechanically moved (i.e. a fan blowing air), that I would call forced convection, so we are in agreement. Water cooling a PC while novel, is not of practical benefit that I can see. Once you get the heat from the processor into the water, you now need to get it into the atmosphere. If you have a chilled water system and cooling tower in your house, you're home free, if not, you'll probably be blowing air through a radiator to get the heat from the water to the atmosphere, so you're back to fans blowing air, albiet in a different spot. Direct compression refrigeration has been used for processor cooling ( http://findarticles.com/p/articles/mi_qa3751/is_200405/ai_n9388151/ ), extremely painful to do, but possible. |

But I wasn't using big heavy video cards; and the cabs aren't being moved around at all. |

I've built several cabinets and when possible I leave the PC in a case. If they aren't in a case, I mount them to the side of the cab. I wouldn't buy a computer case just to mount it to the floor of a cabinet. Air flow hasn't been a major issue since these are full sized machines and I'm not using components which require much cooling. We can debate the heat issue all we want, but in practice I have several machines running for years. |

thank you all for the input. i just want to be sure as i have my cpu overclocked and the power supply has a fan right over it, drawing air in off the processor and then out the back of the case. so i'm just a bit concerned with it being overclocked. thanks, tony |

If you keep the loading off the cable into the card, even the friction from the card to MB connector will keep the board pretty secure. --- End quote --- Zip ties work too. Regarding temperature issues, can anyone cite a single occurance of a standard non-overheating PC, overheating in a standard upright unventilated MAME cab? The closest thing I can find to it ever happening was a guy running a Dell laptop (which already get so hot they can burn you) inside a half-height cab. I think the overheating MAME cab is a myth. |
