    Lightbulb PC Cooling

    Anyone here know the best way to keep a PC cool, as tempreture is often getting up to 48c (on cpu, system temp of 40/41) when playing games now. Have 4 80mm fans on pc (2 rear, 1 side and 1 CPU) as well as 2 fans on PSU. Just noticed that the 3 on rear/side are all blowing into the case. Which would be the best to turn around so that i can a flow of air gowing through the pc, as i am guessing it would be a lot better to have 1/2 sucking air out and 1 or 2 sucking air in.

    I think one on side should be sucking out, but then would the warm air being blown out of the PSU be sucked back in by the rear fans?

    At least at this time of year the room is cooler so it isn't as much of an issue but in summer they will be blowing in warmer air.

    PS can't afford water cooling as they are other things i want to buy first

    edit: normal temp when not playing games can be keep under 35c without the CPU fan running high spped

    you are meant to have the fans at the back blowing out really.....

    fans at front/side blowing in - that way you get a good flow of air.

    make sure there's no shite built up inside and clogging the fans/covering the heatsinks. And other than that i wouldn't worry - the temps aren't that bad, 48 under load is perfectly acceptable (what processor you running?)

    sorry know nothing about doing any sort of pc cooling.

    If it's a stock HSF that u got with the processor then their always a bit shit and never cool as well as a decent aftermarket one like a Coolermaster etc .. also they use thermal pads and not paste which isnt the best for conducting the heat ... Arctic Silver comes in handy here to put between cpu and hsf. next ... fans at front blow in, fans at rear blow out... through-flow.

    If you want it reallly cool ... Water cool it ... see pic in post above

    yeah would like water cooling but would rather spend the cash on a new graphics card.

    It is the standard HSF that came with CPU (64bit AMD 3500+) so could look at upgrading that. Never saw the temp go over 45c before, gradually seems to be increasing overtime, or maybe the games are just straining it more, Have got a 120mm so could try and fit that to the front but need some big screws or something to go through it, but with the 4 fans + 2 PSU fans + graphic card fan and small mother board fan, there is already a fair amount of noise from them. Will turn the rear fans around to blow out cheers all

    EDIT pic above seems a little ott hehe

    Need Posotive Case pressure, so really more intake fans than exhaust fans.
    I've got one on either side of the case....and one in the front, and one blowing out of the back, also a dual fan psu blowing air straight through.

    Remeber the golden rule! Allow enough space behind the PC for the air to escape. If there is no room behind all you do is trap the air in.
