i see you want to have your computer in your room, i used to have my pc in my room as well but it got very annoying, it was too loud so i shifted it and also becuase it distracted me when i had to do some homework or study, so i think you do need some good quality quiet cooling, have you considered watercooling because that is quite a system you have there or if you are going to overclock.

302050 2004-12-11 21:37:00 >t the back of my case is 2x 80mm fan spacings

it is preffable to fill both fan spacings with fans. if you only use one fan block the other space off otherwise the rear fan can suck hot air back in a loop. if you want a quiet pc try not to install a front case fan, they are simply way to noisy for gain in airflow.

302051 2004-12-11 22:45:00 Your reacting to an issue you haven't conformed you actually have, don't add anything to it unless you have proof of a heating problem .

If on the other hand your relying on the standard HSF and a no-name PSU and you want the thing to be quiet, I would be more inclined to replace the stock CPU HSF with a more efficient Heatsink and quite (slower) fan . What's the power supply (read the label), does it have acceptable, quiet, cooling (the PSU should be you major air/heat extraction unit) . The next biggie to look at (or in some instances the first) is the graphics card, does it have one of those jet turbines on it, can you fit an after market, quiet cooler .

As has been stated, if you can get acceptable cooling and air extraction without adding fans, block the un-needed fan holes to improve airflow efficiency and reduce noise .

302052 2004-12-12 01:22:00 yes thats true, maybe i am overreacting, but better be safe than sorry. Re prescott, i am going into year 13 next year, but i am not like some people who will just leave their computer going all the time, i will turn it off every night, its just habbit, as for study and homework, thats a big issue i will have to contend with. I was considering purchasing a laptop, but for the money needed for an ok laptop, i could just not afford it, this machine has been quite budget, only costing me about $1400, while leaving me with a machine that will perform ok in 2 or 3 years, not super fast, but obviously do what i want. I really dont see the point in everyone having a laptop for uni, just more stuff to go wrong, and a lot more money that could be spent on fees etc. Tux (606)
302053 2004-12-12 02:08:00 yea same here, im gonna be year 13 next year aswell, i _might_ be looking into getting a laptop aswell but im not to sure yet Prescott (11)
302054 2004-12-12 02:09:00 In fact, it's probably best to leave unused fan spaces open . :D

Blocking these holes will force the air sucked or blown by the powersupply fan to go through any small apertures there are, say in the floppy drive (if there is one), or CD/DVD drive . This will reduce the air flow .

What you need is air flow . It doesn't matter how good the heat "sinks" and their fans are, the heated air that comes off them has to be removed, and replaced with cooler air from outside the case .

If there isn't a good flow of air through the case the CPU or video fans just stir the air in the box . That doesn't keep things cool .

302055 2004-12-12 03:14:00 I should've explained myself a little better .

The fan holes that should be blocked, IMO, are the ones provided to mount extra case fans in the sides, top or rear . Where an inlet hole is provided for a front case fan below the drive bays, this should be left whether a fan is in it or not because it is the standard place for the fresh air inlet and more useful in that regard than the other locations, in general . Unless you've got a hot graphics card or some such, the rear fans serve little purpose for a standard setup, a good PSU is all you need for extraction with passive venting low in the case . This is only applicable for a tower case of course .

302056 2004-12-17 12:18:00 its finished, i checked the heat and it turned out to average 51 degrees, but it errored once giving me a reading of 71 degrees, still think i need cooling? Tux (606)
302057 2004-12-17 12:53:00 51 degrees is fine :). If that's your temperature you don't need extra cooling. However, I recommend running Prime95 for a few hours, and see what readings you get then... george12 (7)
302058 2004-12-17 15:13:00 dude... two words... under and volt...

undervolt your fans... most run on 12v rail right? Just get your dual 80mm's have them both shooting out, swap the 5v around with the 12v on watever your fan connects to.

Viola.

Or you could even get one of those flip switches from dse or jaycar and make it so you can have 12 volt fan or 5 volt fan. Maybe even get a 3 pole and have an off position.

Simple!!! :D:D:D
