madboy33 Posted June 7, 2003 Report Share Posted June 7, 2003 Hi allI fitted a new case fan about 4 weeks ago, the question is thisHow do i know if it is the right way round?1 Are the blades supposed to be facing inwards and the motor sitting against the case?or2 Are the blades supposed to be facing outwards with the motor pointing inwards?

mark2 Posted June 7, 2003 Report Share Posted June 7, 2003 Where have you fitted the fan, do you want it to suck cool air in or blow air out ? Quote Link to comment Share on other sites More sharing options...
madboy33 Posted June 7, 2003 Author Report Share Posted June 7, 2003 I want to blow air in markIt is fitted at the back, i will take a picture and post back Quote Link to comment Share on other sites More sharing options...
madboy33 Posted June 7, 2003 Author Report Share Posted June 7, 2003 here is the picture the motor is against the back of the PCis that right ? Quote Link to comment Share on other sites More sharing options...
mark2 Posted June 7, 2003 Report Share Posted June 7, 2003 Looking at your pic as it is fitted you need the fan to rotate clockwise, can you see the fan when it slows down Quote Link to comment Share on other sites More sharing options...
Guest ellas Posted June 7, 2003 Report Share Posted June 7, 2003 no the wires should be facing outwards,look at the psu fan you can see the wires thats how the case fan should be same as psu fan. Quote Link to comment Share on other sites More sharing options...

Guest ellas Posted June 7, 2003 Report Share Posted June 7, 2003 madboy you want to blow the hot air out,its sitting right next to your graphics card with its fan so you need to get rid of the hot air. Quote Link to comment Share on other sites More sharing options...
madboy33 Posted June 7, 2003 Author Report Share Posted June 7, 2003 ok thenby the looks of it the fan was the right way round in the 1st placejust changed it round motherboard temperature has gone up from 30 degrees to 36 degreesalso cpu has gone up from 40 degrees to 45 degrees Quote Link to comment Share on other sites More sharing options...

Guest ellas Posted June 7, 2003 Report Share Posted June 7, 2003 quote from overclockers In a computer case, air heated by the CPU, video card, optical drives, etc. rises and 'gets stuck' at the top of the case. This raises the case's ambient temperature and causes all internal components to run a notch warmer than favourable - a common culprit for system instabilities. This is where the chimney blowhole comes in - it blows all that hot air out of the case and helps keep the inside of the case at a comfortable, near room temperature. Case fans in a chimney blowhole setup usually exhaust air, or blow it out of, the case. Quote Link to comment Share on other sites More sharing options...
mark2 Posted June 7, 2003 Report Share Posted June 7, 2003 Are the temps still rising ?? maybe run a comparison test for an hour with it installed either way ? Quote Link to comment Share on other sites More sharing options...
madboy33 Posted June 7, 2003 Author Report Share Posted June 7, 2003 turned the fan back around to the way it was and the temps are lower than before Quote Link to comment Share on other sites More sharing options...
Guest ellas Posted June 7, 2003 Report Share Posted June 7, 2003 madboy them temps are still fine dont forget though you have a geforce 4 to think about that generates a lot of heat the case fan is most likely to help keep that cool.

madboy33 Posted June 7, 2003 Author Report Share Posted June 7, 2003 so are we all saying that blades facing in are the right way?i can feel the air being pushed out of the back of the case Quote Link to comment Share on other sites More sharing options...
Guest ellas Posted June 7, 2003 Report Share Posted June 7, 2003 madboy all I can say is my wires (the red and black)are between the fan and case,look at your psu fan from the back of the case and it should be fitted the same way,best one to talk to is paul Quote Link to comment Share on other sites More sharing options...
