| 775415 | 2009-05-20 09:38:00 | so do they both suck the same way? If you are only talking about a CPU fan both will suck air out of the case and push it on to the heat sink in order to cool the CPU. Do you mean that the fans (CPU) revolve clockwise or anticlockwise to achieve the same result. All fans (for CPU )to me revolve clockwise which unless you put it in upside down would mean that the fan would blow rather than suck. What, really, is your question? Most vacuum cleaners have fans in them. You can use use some vacuum cleaners with the right attachments to spray paint for example. If the fan was sucking I guess you might get a load of paint inside the cleaner. If the fan was blowing you may get the desired result or not. To check this wave your hand over the PSU unit outside the case. Can you feel warm air coming out? So if you can it is blowing air out of the case and cooling the PSU. Therefore it will be sucking on the inside but from where you are it will be blowing. We have been though this issue before. |

| 775416 | 2009-05-20 11:42:00 | Hey I am wondering if any one knows what direction AMD and INTEL fans move air both blow air on the cpu heatsink. however there are a few odd heatsinks that are specially designed to work the other way around. The oh-so-simple remedy is to simply flip your case fan over, reversing the air flow - so it blows cool air into the case. 4 screws out, flip, 4 screws back in, done. very bad idea. that will suck in all the hot air from the other rear fans (such as psu) and will cook the pc. what you really need to do is fit a front case fan that flows more than all the rear fans. the downside to that is it increases the noise. tho that won't help a lot with dust build up except it tends to blow out what it blows in. if your seeing dust build up aroudn the edges of the case it measn the inlet isn't big enough. |

| 775417 | 2009-05-20 13:09:00 | Alrite then, grab yourself a copy of SpeedFan (www.almico.com/speedfan.php). Run it. Then flip yer fan & run SpeedFan again. (I did this long ago when testing this method out. It aint newbie waffle. It works.) Cook your PC? Oh dear. |

Hmmmm..... I have not yet seen AMD or Intel fans in a case other than over the CPU. Some people I note have the case on the floor so the front fan can suck the air through the case along with all carpet fibres and dust mites etc. Some people have a case on the desk with a side fan which can also blow greeblies into the case. Before anyone says there house is 100% free of unwanted dust I suggest they look out the window at or near dawn or dusk. You may see particles floating or not in the room you are in. |

| 775420 | 2009-05-20 19:35:00 | Here's some simple experiments for you - to go with your simple logic . Wet your hand (to amplify the feeling & negate the warmth of your breath) now hold it in front of your mouth . Blow on it - exhale . Now the reverse, inhale . Which one makes your hand feel cooler? Got a reversible vacuum cleaner? Give that a go . Which airflow direction makes your hand cooler? Blowing or sucking? When you burn your finger - do you blow cool air onto it? Or suck warm air away from it? Or, let's take it up in scale & swap appendages for electronics, hence bringing it back to the original argument . Take the side off your desktop box . What would you rather use to cool the insides with, a fan or a vacuum cleaner? In summer, does your car's air conditioning blow cold air into the cabin? Or have you reversed the fan to suck all the hot air out instead? (You might be onto something here! Don't give up your day job yet though . ) How's your simple logic going? Actually, I do remember one case manufacturer that provided a rear intake fan rather than exhaust - Lian Li . |

My case has a 100mm fan in front that sucks cold air in and another at the back that sucks hot air out. Only problem . my ash tray sits right in front of the front fan. The smoke rises verticaly and when it reaches the fan it turns 90* straight into the case. I've often wondered what it would do to cooling if I reversed the fans and sucked fresh air in the back and out the front |

I've often wondered what it would do to cooling if I reversed the fans and sucked fresh air in the back and out the front Blow ash all over your desk. But it would still cool - its airflow - so long as you reversed both, and you have good cable management. Although the PSU does the same thing too you know. |

Actually, I do remember one case manufacturer that provided a rear intake fan rather than exhaust - Lian Li . You really don't understand the principles involved here, do you . Go find yourself a physics textbook . Find the section dealing with energy, specifically heat transfer . Read it . You might also want to consider the fact that your blow / suck experiments are badly flawed - if you want to prove something, you need to design your experiment in such a way that any external influences are identical for each step (or removed entirely, but that isn't always possible) . |
