| 775406 | 2009-05-20 05:45:00 | You're talking about CPU fans? All standard fans push air toward the back of the fan, eg down onto the CPU. | wratterus (105) | ||
| 775407 | 2009-05-20 05:47:00 | i was told that one sucks air on to the cpu cooler and the other sucks air through the cooler then up and off the cpu cooler | nedkelly (9059) | ||
| 775408 | 2009-05-20 05:47:00 | Hey I am wondering if any one knows what direction AMD and INTEL fans move air Usually pull air down through the fan and out through the heatsink. You see some cases that have a tunnel from the side cover over the CPU fan so that it can pull cool air from outside the case. |

| 775409 | 2009-05-20 05:50:00 | so do they both suck the same way? | nedkelly (9059) | ||
| 775410 | 2009-05-20 05:52:00 | so do they both suck the same way? Yup, just double-checked a couple of AMDs in the workshop and they are sucking down through the fan onto the heatsink. |

| 775411 | 2009-05-20 05:56:00 | one sucks air on to the cpu cooler and the other sucks air through the cooler Other what? There is only one fan on a CPU - whether or not its Intel or AMD. And they all push air onto the heatsink, always have. |

| 775413 | 2009-05-20 06:18:00 | That one's pretty straight forward, you need the constant flow of force-fed air onto the heat sink to prevent instant burn-out. Where the manufacturers do have it cocked-up is the case fans though. Every case with a single extraction fan is doing it the wrong way round. Extracting air means the case has slightly less air pressure than the surrounding environment. Less air pressure means less cooling air available (this is NOT ideal). Also, when you switch off, the last action is sucking air into the case (via all other inlets) - hence the monstrous internal dust build-up (a la vacuum cleaner), even in spotless homes. 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. Fresh air being forced in = better cooling, and slightly more air pressure than the surrounding environment means the final action is puffing air out of the box - no more dust bunnies! Try it, it's one of the simplest improvements you can make to your desktop box. |

By all means add an intake fan at the front, but flipping the rear fan is a bad idea. If your power supply has an exhaust fan (and almost all of them do) then your 'remedy' is even worse, because it just shuttles cool air round in a circle between the rear fan and the PSU fan, and does almost no real cooling work. ...means the final action is puffing air out of the box - no more dust bunnies!Rubbish. You'll still get just as much dust in the case, no matter which way round you flip the fan - you're still shifting the same volume of dust-laden air through the interior of your computer system. |
