| 654337 | 2008-03-30 21:05:00 | :help: My PC Case has a 12 cm side fan. The temperature inside was average about 38 degrees After I disconnected the side fan, the temperature stays about 32 degrees... Has anybody got an explanation for this - I feel I just have to understand it!!!:drool |

| 654338 | 2008-03-30 21:19:00 | its not the number of fans but how they work together to give your case airflow that is important. Often a side fan will be blowing across the airflow created by other fans and so stop the hot air being moved out of the case causing temps to increase. Manufacturers of the lower end cases put side fans etc in because it helps sell more cases. It is more effective to have good fans blowing the air from the front and fans sucking from the rear to move the cool air in from the front, past all your hot bits and cool them down and finally get blown out the rear. www.silentpcreview.com has some pretty good articles on fans and placement. |

| 654339 | 2008-03-30 21:38:00 | a lot of cases really do have poor cooling design. most are made to look good. to many fans (or high air speed) can cause layering, where the airflow goes in and straight out without actually circulating and cooling anything. also it depends on what temp your quoting and where its measured. the other thing to look at is where the pc is placed, ie under desk, by a wall/cupboard where it can suck the hot exhaust air back into the intake. very easily done with big side fans. |

| 654340 | 2008-04-03 05:39:00 | well, what do you reckon would happen if i took out the side fan and turned it around so that it's no longer output but input? | pingu45 (13461) | ||
