Ok i built a new pc but made a error, its a small case and the psu sits directly above the CPU hs/f (3rd party zalman one) , the problem is the OCZ 500w one i have for some bizaar reason blows air onto the cpu, so the air the cpu is blowing off is comming back with more heat. Luckyly i have a Silverstone extractor that sits inbertween that extracts the air, but its still hotter then it should be, plus if i add a vga card to the case it wont help.
Now i have no idea why psus would blow air into a case, but im ganna have to buy a new one, 500wats will be enough for what i use (average gamer, will have 1 gaphics card in tehre at one point, AMD phenome x4 955BE 3.2 ghz 8gb ram.
so i need a psu that will extract air and blow it out the back of the case. This will allow me to lower fan speeds and lesten noise + temps.
have to 120mm ultra quite temp driven fans on the frount so they blow air in without making a racket, hace the silverstone extractor in the back to suck air out, another extractor on the psu would make great airflow and would be quite,
also if sombody could recomend a extractor expansion slot fan that doesnt make a raket and is silent be fantastic
Wake up man !! PSU's are supposed to EXTRACT from your case RMA that sucker or take it apart and reverse the fan,usually the sticker is in the direction of the air flow,,and most psu's are mounted above the cpu,,,quickly now replace that sucker...
I also thought all psus extracted air so i didnt think twice when buying, and knowingn the heat off the psu can be around the cpu this puts a strain on the cpu fan to be working fulll blast all the time. 4th pc i built nd 1st time iv come across this.
I would look at the raidmax hybrid 2-RX 530w for $54.98 with free shipping plus a $15 rebate at newegg.com. It has a huge 135mm fan, which my superflower has. This size fan should move plenty of warm air out of your case.
i took the psu out of the case again to test and its 100% definatly pusing air downwards onto the psu, which ever way i hold it up, its the same, as for the cpu fan im using a Zalman VF2000-LED http://www.ebuyer.com/product/167783 , i can control the speed if the cpufan via a dial that came with it. When i turn it all the way down it heats up. However when i tun it down a very feint flow comes out the back of the cpu but its hard to detirmin if its just the air passing though from the cpu fan. But its almost notting compared to a generic psu i tested that blasts it out the back or my old thermaltake one that had a fan in the bottom and back. (are psus like this still made i coudnt find one.
I had a look on the psu box and it says 140mm "top mounted fan" , should i of got a bottom mounted one?
