Hello...
I have 3 case fans in my computer...
I have it blowing in...
The inside of my computer is fairly cold...
My room is not hot... not warm but fairly even...
Is that good or bad?

hmmm, although its might not sound much, the idea is to remove the heat from within you comp box, to effectivly do this flow through is important
it no good trying to pump shit loads of air in if it all cant get out.
best bet is to try and have an air intake = air exhaust
if you have 3 case fans installed then all the holes to let the air out will be blocked
try reversing at least 1 of the fans if not 2, so airflow will increase over the board and out of the case
its pretty technical but if you have all your fans blowing inward, and no way to get that air out you will create a positive pressure inside the case, and this will infact increase the internal temp, same will happen if you have all the fans blowing
this theory comes from speaker technology, where high powered subs get fried cause the airflow is too low or is unable to escape.
room temp ( ambient temp ) will effect the comp temp no matter what you do as the air has to come from somewhere and go somewhere
It's a nice theory, but translates poorly to computers.ts pretty technical but if you have all your fans blowing inward, and no way to get that air out you will create a positive pressure inside the case, and this will infact increase the internal temp, same will happen if you have all the fans blowing

I have yet to see a computer case that wasn't riddled with holes, vents, loose joints, etc.
The concept of "establishing pressure" ( be it positive or negative) in the average PC enclosure is laughable, IMO.
Furthermore, using the typical 80mm case fan, "airflow" through a mid-tower sized case doesn't occur either. Simply put, a axial 80mm fan just doesn't expel a stream of moving air coherent enough to be described as a continuous "flow".
All the pretty pictures of case interiors with arrows depicting the flow of air ( Apple seems fond of this image) are figments of the marketing department's imagination.
Grub, ignore for a moment the theory of case fan placement and concentrate instead on your temps.
Which you failed to mention.

The only consideration I heed is that heat rises so the rear case and PSU fans blow out, while my case front blows in.
I doubt it makes a lot of difference (my temps aren't low) but at least it's following the laws of physics to a degree.

How far are you willing to follow the laws of physics?Originally posted by Chewie UK@5 March 2004 - 08:17

Have you tried any other configuration?
You really have nothing to lose, as you've already admitted that your temps "aren't low".

Very true clocker, 80MM fans that people use in their cases just dont give a nice air flow. They can bring in cooler air, and expel hot air, but they dont have enough CFM to create a nice breeze in the case.
Im my previous case, which was a mid tower, I was able to put one of my 120MM panflos on the 5.25 rack, and another in the middle way back of the bottom middle of the case, and I was able to acheive the constant air flow.

Not very far, mate.
I really don't see the point of spending hours/days/weeks fiddling around with modding to allow overclocking because you just end up spending less time actually using it.
Some may consider my Thoroughbred to be too hot at ~50C and I should look into getting it down but, really... it's well below AMD's recommended max temp of 90C and the amount of difference my high temp is gonna make to it's lifespan isn't even worth the effort of working it out!
It would've been nice if manufacturers had thought a little more in designing board formats; why put the CPU at the top of a tower case if heat is an issue? Similarly, why are GPUs situated on the underside of gfx cards when they're in a tower case? Shit, people spend weeks poring over real or perceived heat issues and these simple design features could've given them some sleep!

I agree with what you are saying, particularly about case and component design, but there's a point you've overlooked.
Amd's max temp is the temp above which you are likely to do permanent damage to the chip. They are NOT guaranteeing that the chip will be stable if you operate at temps close to the maximum.
I often find that instability occurs (especially hangups) when Amd chips approach 60C, and often much lower if the chips are overclocked. But that's just a direct consequence of the physics involved, which is why it is important to get lower temps than normal if you are overclocking.
.Political correctness is based on the principle that it's possible to pick up a turd by the clean end.
Chewie,
Many of your concerns will be addressed with the new BTX form factor...coming soon to a theater near you.
It looks to be a little better although they still insist on describing the "airflow" that will cool the processor then continue on to the memory, etc.
Bollocks.

So i should put 2 fans blowing in and 1 blowing out?
