I'm wondering how to get the best cooling performance out of my case. I read somewhere that optimal airflow would be to have the front two fans on low, with the rear fan and the 200mm fan on medium.

i've just had all 4 sit on High.

The Antec Nine Hundred has two 120mm fans mounted at the lower front f the case, a 200mm fan on the top of the case, at the rear (where a PSU would normally go. The PSU is mounted at the bottom), and a 120mm fan at the rear top. I have just a lame CPU fan (probably 92mm or whatever), and a 120mm fan on my PSU. The PSU is mounted upside down, due the the case having the PSU mounted on the bottom.

What would be the best way to keep a video card cool? I can install two more 120mm fans (On the side of the case, and there is a mount on the back of the drive cage thing for one), but would prefer not to. I'm in debt already.

I have the same case, and I have the two extra fans. All of them are on low, and all of my components are sufficiently cool.

To keep your video card cool, your best bet would be to use RivaTuner to manually increase the fan on the video card. I have noticed that the fan on the side of the case does keep the video card a bit cooler, due to the fact that is blowing directly on it. However, increasing the GPU fan speed with RivaTuner makes a much larger difference.

I've only just heard about this 'RivaTuner' in the last 24 hours. Would you be able to provide an explanation of what it is and what it does, and perhaps a link?

Oh, how mucher higher is my chance of damaging the fans by leaving them on high all the time?

I've had the fans on my Antec 900 running wide open for several months without a hitch.

I don't think they would be damaged (maybe in the long run they would wear out a bit faster...), but it's just that I like my fans to sound like fans, not like a jet engine.

Gotta love Google, eh?

Thanks. Much appreciated. I don't have much time for googling things right now. Running between this computer, a old really bad laptop i'm trying to install Ubuntu onto, homework, and my guitars.

I really appreciate you guys actually going to the trouble of typing something into google for me

I just sold my antec 900 to a budie but I had it for 2 years and ran the fans on high all the time left it on all night and all day. The case has good cooling. I would not think running your fans on high will not hurt it If you can put up with the extra sound. The worst part of the case when I owned it was all the dust. Thing was like a vacume cleaner. It was also kinda a pain to hide all the cables but you can do it. Easy to buy antec tri cool fans to change the color or replace them if they go out.
