Tech Time Episode II: Attack of the Fans

What is a good way to evaluate/improve the airflow in my computer (such as switching fans around, moving cards, etc), unless a case temp of 107F/42C is ok. If a web site spells all of this out, let me know :-P Thanks
Comments
Take the case cover off.
Place a large 6" or bigger fan next to computer.
Turn fan on.

Damn...Your pc must be just a wee bit noisy to say the least... [img]http://216.15.145.59/mainforums/wink.gif[/img].
Are you still using standard IDE cables?...I'm asking since there's rounded ones that improve the airflow inside the case as well as looking pretty neat...

The web server has 9 fans running in it. [img]http://216.15.145.59/mainforums/smile.gif[/img]

But on the other hand you're probably not right beside the server several hours at a time everyday either,right???...

My webserver only had 2 fans, a 6 inch fan and a 9 inch fan, i took the 9 inch fan out when i noticed that the temp was fine without it, and there was so much airflow in the machine that i ended up with a coating of thick dust over the intake...

I was thinking they were going to call me and tell me it was too loud. :P Of course, when you've got another 500+ in your data center, it really doesn't matter. [img]http://216.15.145.59/mainforums/smile.gif[/img]

mod it so it comes out the front
then you got snow cones and a cooling system.
I'd add 2 fans. An intake-fan on the front down and an exhaust-fan on the back top (above the power suppyl).
That way you get an airflow from front/down over the cpu to back/top.
With this configuration I gaet a casetemp. of 33C on a simmilar system (although I only have a 1.2Ghz CPU)
Intake in the front.
3 in the back:
The powersupply is outtake (duh!)
A fan under the power supply is an intake.
This blows right over the CPU.
A fan that sits in a PCI slot right under the grafics card is another outtake. But there are alot of wires and crap that probably are interfering with the airflow. I don't want to add more fans because I'm in a dorm room and don't want to keep both my room mate and me up!
Generally, you want a flow in your case from bottom front to top back.

Well, since I am getting an upgraded vid card and another HD, that means I needed a higher wattage power supply. This resulted in my realization that my system temperature, which was already on the high side, would be getting even higher.
Needless to say, I've ordered a 120mm fan for that back opening now [img]http://216.15.145.59/mainforums/smile.gif[/img]. And a slot fan for below my PCI slots...
My 1.4 Althon XP is also running at 132F/55C with Seti@home on. The max temp for my chip is around 150F, but that doesn't mean that is what it should be. Is my chip too hot too?
I wish my looks could be as hot as the computer. Hehe.
The standard temp of 132F/55C is a little bit high.
A too high max.temp will cause frequent crashes and can (in extreme cases) fry the CPU. Don't worry about that. Here you're in the safe range.
A too high standard temp doesn't cause crashes and won't fry the CPU on the spot, but it reduces the CPUs lifetime.
Standard temp should be around 45C, at most 50C.
55C will affect the CPUs lifetime.
A stonger intake can help.
You might also try to clean the CPU-heatsink. High-end Heatsinks often have very thin grooves for heatexchange and they tend to get bunged up with dirt. This reduces the heat-exchange and thereby the overall efficiency of your heatsink.

That 120mm fan, and a single 80mm fan should be sufficient if your case has decent airflow. If you're really desperate, you could cut a hole in the side of your case and mount a fan there.

(my fans are in)
As for noise with these fans, the 120mm I got has a manual speed control. The loudest fan is still my Power Supply fan, and you don't notice the added ones.
As for why I needed the 120, this case had a BIG vent hole in the back...and I was getting loop air flow right out the power supply and back in over the CPU...not good.
As for why I needed the Slot fan, well...I just installed a new top vid card that will put out a lot of heat when used...and I want to vent that right out the case instead of up to the other fans...
