hemirunner426 Posted June 18, 2002 Share Posted June 18, 2002 which system do you guys think would be be best in this application??? any ideas... its an ATX case... i've read that you should have that fan blowing air into the case for a positive pressure... then i've also read for an ATX case you should have that fan blowing out the hot air so it doesnt fight with the PSU FAN... any ideas?

Guest xiphias Posted June 18, 2002 Share Posted June 18, 2002 the ideal setup would be to have a fan at the front of yr case sucking cool air in and an exhaust fan under ur psu there to suck the hot air out... thats how mine is setup and case temps have dropped bout 10 degrees ©. Also an idea would be to have a fan on top sucking hot air out since hot air rises... just a thought Link to comment Share on other sites More sharing options...
hemirunner426 Posted June 18, 2002 Author Share Posted June 18, 2002 in order for me to "correctly" put a fan in the front of the case i would just have to buy a new one... there are no spaces there to put a fan i've tried the case fan running both ways... with it blowing hot air out... the case temps have dropped around 7C... but CPU temps have risen about 3C... w/ it blowing cool air into the case... case temp rises about 7C and the CPU temps drop about 3C its a weird trade off... i have no clue which one i should go with... another thing i've noticed is the case (by touch) feels cooler with it sucking out the hot air im just worried that the HSF is being choked by this setup i could "set" a fan up against the vent holes infront of the case... im not sure if that would help any though since there is so much restriction...

Guest xiphias Posted June 18, 2002 Share Posted June 18, 2002 its strange to see cpu temps rise after case temps have dropped... this is certainly not the case with my PC... very strange indeed. Hopefully some other members can shed some light on what is happening here. Link to comment Share on other sites More sharing options...
tobeh Posted June 18, 2002 Share Posted June 18, 2002 just cut a hole in the front of your case and put and attatch a fan there using some screws,simple!you want it blowing out of the case, also ideally you want a top blowhole blowing out and a side blowhole blowing onto your cpu and gpu Link to comment Share on other sites More sharing options...
hemirunner426 Posted June 18, 2002 Author Share Posted June 18, 2002 the only reason i can think of why cpu temp would rise and case temps drop would be because the fan is drawing all the hot case air over the CPU HSF and out the back... when the fan is turned around... it blows cool air onto the HSF causing it to drop in temperature... but that air is heated by the HSF casuing it to be useless for cooling the rest of the case Link to comment Share on other sites More sharing options...
Lezend Posted June 18, 2002 Share Posted June 18, 2002 from my experience, do not put intake fan. if you have aluminum case, you shouldn't even need intake fan... all fan should be exhault because intake are bad for case... it bring in dust and craps. people said that you need air flow... that just blow... you don't need air flow... if all the heat get vaccum out.. there no need... you always want it to be a dust free environment .. best is to keep it isolated vaccum dust free...best optimized. my pentium 4 never get dusty and the best idle temp i got is 22C.

hemirunner426 Posted June 18, 2002 Author Share Posted June 18, 2002 since i've installed the vocano 7... my CPU temp at idle is around 39C... and at load it hits about 50C... never above, which is nice, because before i installed that HSF it would idle at 45C and hit almost 60C at load... my case temperatures are reporting though at idle around 45C... and at max they hit 50C. When the case fan was blowing air into the case... it would hover at 50C +- 1C and never move. Right now the case fan is sucking the air out of the case and the case in general feels cooler to the touch. The front (were the drives are) used to be hot to the touch, but not anymore... same with the side panels. I dont understand why it would be so high though unless the temperature is being read from a nearby heat source... IE.. the chipset (nForce 420)... i do have the onboard g/f card overclocked... but its getting replaced soon w/ a gForce 3 so that might lessen the temperatures in those areas...

tobeh Posted June 18, 2002 Share Posted June 18, 2002 Lezend: ever tried fan filters?all cases need to get air into them thats what the little holes on the sides and front of most cases are which bring in dust, the best way to stop dust is to have some filters on fans blowing in and block up all other holes and you should clean your pcs gubbins and bits every once in a while anyways!

Lezend Posted June 18, 2002 Share Posted June 18, 2002 Fan filter and noise damber is nothing but insolation to the heat. I said you don't need intake fan (fan that blow into the case). All you need is exhaust fans (blow outside of the case). If you have exhaust fan... The air will flow in by it self and it will enter the inlet grill. This will minimize the dust which is suck into the case by fans. Link to comment Share on other sites More sharing options...
