osamio Posted January 12, 2011 Report Share Posted January 12, 2011 I have a soundstream DTR amplifier, and with the way the feet work, if you mount it horizontally, it leaves about 1-2 cm between the amp and the wood it's mounted too. I cut out the square for the exhaust fan in the wood where the amp will be mounted above it, now the question is, should i point the fan down so it sucks air away from the amp, or should i face it toward the amp so it blows air over it? It is a tight space so i think the suction will have an affect..as well as blowing, will one work better than the other or does it matter? 2009 Cobalt LT Pioneer Headunit 2x Pioneer 6 1/2 (stock amp) 2x Pioneer 1" tweeters (stock amp) 2x Pioneer 6x9 (stock amp 4x Pioneer 6 1/2 Pioneer GM-6400F Soundstream DTR 1700 R.I.P 2x Champion series PRO 12" subs 0 AWG Big 3, Stinger SP1700 battery To come: New or repaired DTR!!

skittlesRgood Posted January 12, 2011 Report Share Posted January 12, 2011 its the same thing either way. the air blowing out of the fan is the same volume as the air being sucked in. that is if its in an amp rack. if your just mounting a fan to move air over the amp then i would have it blow at it. remember a fan needs to breathe. if it doesnt have the same open space and the surface area of the fan, in front and behind it, then you are choking the fan. so if a 3" fan only had 2cm in front of it... it wouldnt move much air. can you post some pics of the setup? i can help you out on the best cooling option if i can see what you want done. If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

The fan is actaully 2 cm plus an inch of wood away from the amp, i was out working on it just now and it was easier to drill holes through the wood the size of the fan, as opposed to mounting the whole fan into the wood, and theres plenty of room behind the fan, i think based on how the way the air is gonna flow, i'm gonna have it blowing on the amp. I can't find my charge for my camera battery or i'd show u the setup. thanks for the reply 2009 Cobalt LT Pioneer Headunit 2x Pioneer 6 1/2 (stock amp) 2x Pioneer 1" tweeters (stock amp) 2x Pioneer 6x9 (stock amp 4x Pioneer 6 1/2 Pioneer GM-6400F Soundstream DTR 1700 R.I.P 2x Champion series PRO 12" subs 0 AWG Big 3, Stinger SP1700 battery To come: New or repaired DTR!!

skittlesRgood Posted January 12, 2011 Report Share Posted January 12, 2011 but the inch of wood is just a tunnel correct? then the 2cm opening is still what i was talking about. but anyways, is the fan blowing at the bottom of the amp? because it wont do much there. air needs to flow over the heat sink. mostly over the sides where the MOSFETs are mounted. the center of the heat sink gets hot as well.
