Cieling Fan...Up or Down? For heat removal
I've run mine DOWN for 23 years, all year around. I've never seen them
remove heat though. I just don't see the benefit of the fan when it is running in the UP mode. -- Steve Barker YOU should be the one controlling YOUR car.

Considering we're going into the hot season?? thanks Doesn't remove heat from the room but by blowing downward during hot season, the additional movement of air over your exposed skin will cause quicker evaporation of your perspiration and thus cooling of the skin. In the Winter, blowing upward will somewhat force the warmer air that accumulates at the ceiling outward and downward to the level at which you live. You wouldn't want the fan blowing directly down on you, then, as the additional evaporation would chill you. Tom G. |

I have a digital therm and noticed that even thought I FEEL about 10F cooler , the room has actually increased about 0.5-1F ?? Blowing down btw. wtf? |

Yet my body feels about 10F cooler. Didn't help the computer temps which is one I had hoped since the air flow has now increased. Nothing I try works. |

I guess it did add heat because the digi-therm shows nearly 1.0F
increase and the fan is blowing DOWN? Heat rises. Heat that normally lived near and in the ceiling is now being circulated through the room. Also, the fan motor dissipates a few watts as heat though the effect is probably minimal. Didn't help the computer temps which is one I had hoped since the air flow has now increased. I'm assuming you've already blown all of the dust out of your computer, particularly the CPU and power supply. Next step is to add or replace the case fan (separate fan below the power supply or on the front of the case), or add a "slot cooler" or blower that occupies one of the PCI expansion slots in the back of your machine. Shouldn't set you back more than $20. You don't need a fancy lighted turbo-speed L337 overclocker's fan, a simple generic one is fine. |

Try each on a separate day, and see what works.
Window AC, I find they cool better if you point a fan towards the AC. Not sure why, but it works better than having the fan blow out from the AC. -- Christopher A. Young You can't shout down a troll.

They just add airflow, which keeps you cool but not the computer.
The bigger the blades, the more energy-efficient it is. What you want is to move lots of air very slowly, not a little air very fast, for energy considerations. For cooling, I blow air from the basement floor through a flexible duct onto my computer chair, on the hottest days. The resulting heating of the basement floor keeps the house warm then through November. I threw out the heat pump in 1978, when it became apparent it was chiefly a sink for repair dollars, and went to fans. I think it has to be a hobby, though. A woman isn't likely to put up with it. -- Ron Hardin On the internet, nobody knows you're a jerk. |
