my computer is quite noisey... having no money to spend on a quiet fan i sat tight and dealt with it...

so, one day i decided to open the side of my PC case, letting some cool ambient air in. so, since my computer is under a desk, with its left side (front facing us, so our left) facing a piece of wood, i opened up the case a little, leaning the open part of the case against the desk 'wood supporter', leaving a gap that is about 1inch along the top and sides...

my CPU fan speed fropped about 1000 RPM, reducing noise considerably, and my CPU temp dropped from about an average of 53 degrees C to 48 degrees C and my chipset temp from 33 degrees c to 29 degrees c... it is a lot quieter now...
 
??????

You fixed your computer noise by leaning it up against a desk? I don't get it. Either you've got a soundproof desk, or your computer wasn't very noisy to begin with :)

don't have money to spend of a quiet fan?? dear god they only cost like 9 dollars... how do you manage to eat??
 
Computers with open case always run cooler.
I am curious, what kind of CPU cooler are you using? Usually coolers with heat sensors and variable fan speed have two seetings. Your fan probably switched from full speed to quite mode, but I would expect the difference in rpms to be more than 1000.
 
Actually, strange as it sounds, computers with open cases frequently run HOTTER. I know this sounds strange, I was skeptical myself until I actually tested it. If you have your fans set up properly in your case they should pull outside air right over the CPU and then out through the PS. With the case open air just flows in and out everywhere.

There was a nice piece in Maximum PC mag awhile back that discussed this at length, which is what prompted me to test it.

Of course it goes without saying that you have to have the PC in a well ventilated spot in the first place.
 
Yeah that can definately be possible in a machine with really good air flow. However I've always noticed a 5-10C drop in CPU and system temperature when I run without a case, especially in the hot summer months But that's probably because I'm real cheap with the fans and a lot of the cases I've got are cheap (e.g. cluttered).

You are right though, it's all about putting the right air where it needs to be, and then getting rid of it efficiently. If you remove the cover, then the front case fan isn't doing a hell of a lot of good.

i run my PC with one side open as well. i don't know why i don't open the other side up too.

anyway, i drilled a hole from my studio room to an adjacent closet in my wife's office. since the PC sits in the opposite closet, there is no noise in my studio.
 
If your computer ran cooler and quieter when opened, that points to one fact: there wasn't enough exit space for the air in the first place.
 
Tim, that's the case with a LOT of systems though. That's what I get for buying cheap cases where you have to cram everything and there isn't an extra exhaust port in the rear.

It's not such a big deal though. I mean if my CPU is at 50C then that's sort of hot, but not that hot. If I take the case off and get it down to 45C well fine. The only time I do that is when I'm overclocking, which is something that I've just sort of given up on recently (just work, is all I ask, hehe).

webstop: i am using a thermaltake volcano 7

i want to try and get those switches that change the fan speed for when i am recording...

well, when i said i couldn't afford a quiet fan is because i would have to order one online, and then the postage costs as much as 20 fans... so that is why.
 
Lucid - I''m not sure if it'd work or not. Having fans on only one side of the enclosure might do more harm than good.

It's all about getting air into the enclosure :) If fans are only on one side, then there isnt' much of an airflow.

The idea is good, though. Maybe someone with more experience can give us some more tips :) I've been meaning to ask how people deal with fan/computer noise in their studio. I live in an apartment, so I can't drill holes or anything like that, hehe.
 
there seem to be intake and exhaust fans!

two for the front and two for the back!

'they' need to make cool chips...
