Fan Orientation
<div class="IPBDescription">call me noob plz</div> I just bought a new case for my computer complete with window on the side so I can watch all the neat things that go on inside.
Anyways, the case came with one single fan mounted on the middle of the window. I bought 6 more fans and installed them and everything is hunky dory.
My friend says my fans are all backwards.
If you are looking into my case from the window, the 2 fans mounted on the rear of the case above the AGP/PCI slots are spinning clockwise, as was the fan that came pre-installed with the case. The 4 fans in the front of the case (again if you are looking into the case from the outside) are spinning clockwise.
My temperatures are fine. But who is right? I have no idea really, this is the first computer I have put together. I'm not overheating so I don't see a problem.

So you are saying I should reverse them all and see if the temp is lower?
Damn that. What a pain in the ****.
fan(s) in front of case should suck air in
fan(s) in back of case should suck air out
fan(s) on side of case should be in the middle of some form of modded window w/ neon lights or something inside
[edit]For my case, I went with what seemed most logical to me. My 1st sidepanel fan is directly in line with my CPU heatsink/fan combo, so having them blow air at each other would be counterintuitive. The heatsink/fan combo blows air "upwards" away from the CPU, so I have that sidepanel fan taking air directly from it and rocketing it clear outside the case.
My 2nd sidepanel fan also takes air from inside the case and blows it out for similar reasons, only this time for the video cards and sound card instead of the CPU.
My hard drive cooler in the front of the case takes air from outside and sucks it in -- it's one I can't (easily) change. So I decided to orient my other front panel fan in the same direction. Likewise, my power supply fan takes air and blows it from the case to out the back, so I had my other rear fan oriented in the same direction.
Overall effect: air comes in through the front, goes out through the back or side.

This is off-topic but thats the most hilarious thing I've read this hour <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->
No. No you are not.
I have a total of two fans inside my computer. It regularly has little "meltdowns".
*edit* Uh, three. It has one on the processor, one on the graphics card, and one on the power supply *edit*
- put your hand over a fan
- if you feel air, remember that it points out
- vice-versa
all fans in one area or section should point one way
all in the other should point the other way
you said you have 7, make sure 4 point out
if i remember from thermodynamics, try have the front part as intake (cooler air intake is better, you could exhaust into an oven as long as intake is cool enough)
OR:
-listen to marik and doom, they seem smart
Hmmm...I only have two fans, yet my computer is running at a cool 20 degrees C right now, Athlon XP/GF4 and all <!--emo&???--><img src='http://www.unknownworlds.com/forums/html/emoticons/confused.gif' border='0' style='vertical-align:middle' alt='confused.gif'><!--endemo-->
My fan on the side sucks stuff in. my fan on the back blows stuff out. Simple. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->
As noted, just check that you've got a relatively direct airflow path. Meaning not to have an intake between two exhaust fans, or you'll just be circulating hot air instead of passing maximum cooling.
And no, it's not as simple as clockwise or anticlockwise. Some fans are set up backward. Plus, it's much easier to just plug it in and feel which way it moves the air.
The setting... The shopkeeper (Gord) is on hold on the phone while three kids walk in. They see an open PlayStation on the counter, so they walk over to see it.
Then, the obvious intellectual of the group starts in...
"You see, being that I've taken apart and fixed a couple PlayStations, I can tell you what's wrong with this unit. First up, the power switch is missing... and blah blah blah blah."
"Actually, the only thing wrong with that PlayStation is that I haven't put the lid back on it. It's all fixed and ready to go." spoke the Gord.
"Uhm..."
The intake fan on the side of my case just boosts the air, making the exhaust fans' jobs easier. Though I'm considering picking up an HDD cooler unit, with filtered intakes.. give roughly 2:1 (using 30mm on the HDD unit) exhaust/intake, even with the slot cooler just using a pair of 30mm.
