Guest Ace309 Posted December 25, 2002 Report Posted December 25, 2002 I've got a modded case with pretty good airflow. The ambient temp in the case appears to hover in the high 70Fs. I have 80mm fans in the lower front (intake) and upper back (exhaust), along with a 3x40mm intake cooling my hard drive in the upper 5.25" bay that feeds an upper-panel exhaust fan. My question is this. My back-panel exhaust fan is right next to the CPU (and therefore the heatsink fan). I'm using a Volcano 7 HSF sucking (blowing air onto the heatsink) with a 1.1ghz Celeron and haven't had any problems. The thing is, with the exhaust fan blowing out and the HSF sucking in, I imagine that can't be good for airflow. Is it worth inverting the HSF so that it blows out, thus feeding the hot air into the back-panel exhaust fan? Is there a reason the HSF shipped sucking instead of blowing?
Guest MentallyNormal Posted December 27, 2002 Report Posted December 27, 2002 Most fans are suppose to blow down on the heatsink,like you mentioned yours does. It cools off the heat come from the heatsink. An i believe that heat gets sucked up by either your ps fans or that exhaust fan. You can always flip your hs fan to suck air from it and the exhaust will get it. You can try it out to see if your cpu temps increase or decrease. But usually cpu fans are suppose to blow air down onto the heatsink.
