Antec 900 side fan direction?

OK, I've always had the two front and one side fan as intake, using the top and rear fans for exhaust. Well, I put foam filters on the front fans, and reduced their speed to medium. I mainly wanted to try to cut down on the amount of cat hair that love to pile up on the outside of the fans, as well as my CPU cooler. I wasn't able to properly attach a filter to my side fan, so I reduced that to medium as well, but until I can get better VGA and CPU cooling, I wanted to help keep it cool as much as I can, so I turned the side fan back up to high.

When I opened my case to do this, I had to blow some air in there to clear out the cat hair. I only have one cat, but damn if she's not an annoying *****!
It seems that it is mainly entering from that side fan, so I was wondering if would cause problems if I made the side fan as exhaust as well. I think this will help reduce the amount of times I have to go in there with canned air (usually about every two weeks lately), but should also keep it cool.

So will this affect the 'pressure' in my case much?

I've also finally decided that while I really like my case where it is, I think I'm gonna have to get it up a little higher off the floor, so that should help as well.

Anyways, any suggestions would be highly appreciated.

He didnt note ambients but you can get a general idea, its best to test yourself. His results:

Intake 70C
No fan 69C
Exhaust (No filter obviously) 68C

I personally made my side fan blowing inwards since it cools the video card and my top vent back exhaust pulls that hot air out, and my Noctua shoots part of the hot air out of the top vent as well.

Putting it higher up will certainly help, especially if you have pets and carpet. Personally I like a side intake but there are those that have higher cfm fans that feel a side fan ruins their overall case airflow. Blocking it off is not recommended if you need it to keep temps down on your graphics cards. I'd imagine higher cfm exhaust and air filters would be a godsend

Mine is currently an exhaust fan, i took off the plastic, and zip tied it to the wire mess. Its currently a 80mm, but I didn't think a 120mm would fit... Anyone want to trade?

I wish Antec had a step-up program so I could get a 902. Air filters FTW. I actually wish I had carpet, might hold onto some of that cat hair more. But sadly I have nice hardwood floors.

My GPU load temps don't go higher than 65c with it as intake on medium, so I already got him beat...heh...thx tho!

EDIT: also noted that he had the fans speed set to 60%. Mine is at 100%, since noise is not an issue for me.

When I was running on air it seemed to keep my cards cooler with it blowing out. Helped remove the heat off the cards from the case.

Turn that puppy around
I have filters on my front fans also. Blasted cat hair!

Thanks all! Think I'll see what happens when I turn it around!

+rep!
My antec tri cool fan is silent, is crazy.

Well, it's no official 'long-term' testing, but I'm running about a degree warmer with it as exhaust. It's no biggie, but I really miss my one degree, so it looks like I'm putting it back to intake, and gonna have to put the case up on some milk-crates.

Ah well, at least I'll be able to look at the side window more.


EDIT: actually looks to be a few degrees warmer. Time to shave the *****...cat that is...

How does it affect the overall temperature of your case over time? Try it with a long gaming session or loop Vantage.

Are you using the plastic window thing that came mounted on it?

Also, what size fan are you using?

A 120mm Tricool, and yes I have the plastic on, otherwise I'd have even more cat hair. I also don't think you're getting my question. I'm was only really trying to reduce the cat hair build up by making it exhaust. With it set up as it was, my temps were great, unless it was overly warm in my apartment.

Yeah I think I might do that, but when it was intake a few minutes ago, my 9800GTX idle temp was 39c-41c...now as exhaust it's a solid 45c. Also the 8400gs was idling at about 45c-47c and is now 51c.

Well, thats an easy one if you think about it, filters... that would be truly the only way. Sucks for me, my heat sink is so big, that i cannot fit a fan on that plastic thing and use it, my heatsink is like 1 inch away from the panel.

You can easily turn the plastic around so the fan is on the outside of the panel.

OP, do you have a fan on the inside of the HDD cage blowing in front of the cards. If not, you could move the panel door fan to the inside of the case blowing air from the front. Turn the two fans that would be blowing inline on high and leave the others on low or medium.

Are you talking about the black thing that attaches to the cages? If so, with my current layout inside, I couldn't fit that on, since my 9800GTX is a big mofo. However, I'm also thinking of rearranging some things; maybe moving my burners and Audigy front panel to the bottom, and putting the HDD's up top. Though I still wouldn't be able to fit an internal fan, due to my GPU.

The HDD cages are very adjustable. I was able to put a fan in the black thing on the cage when I had my Ultra installed. You have to move the HDD cages forward just a hair and it will fit with the fan right up next to the card. I believe the Ultra is the same size as your GTX.

just so you guys know.....I have the a900, overclocked quad, and a big gpu......

I ran before and after tests, including both directions, and the side fan only threw off the balance and made my temps slightly higher.....exhaust or intake...it doesn't matter...

I highly doubt antec did the math when adding the side fan capability. I made a thread reporting the results and what I did with it, and I had like 3-4 pages of replies from people saying the same thing. It seems the fan configuration you get stock is perfect....if you throw off that balance it messes with the flow.

To get to the point.....I took that perfectly good 120 fan and gutted it since acting as a side fan was useless, and turned it into a shroud for my TRUE, to help with air friction noise.....that's how useless the side fan on this case is.
