New Fan Placement

[TehMaster]

Hey Guys. First post on my new name!! Anywayz, i am installing a new case fan (or 2) and would like somebody's imput on if it might disrupt my air flow. Right now, i have 5 case fans: 2 front intake, 2 rear exaust, and i side intake. I am installing 2 new 92 Tornados. I know, they are loud as all hell. Like a leaf blower. Anywayz, i want to install one on the top for exaust, and the other on the side as another intake. Do you think the top fan will help, or just mess up air flow?

Thanks Guys

WELCOME TO THE FORUMS!!!

The top exhaust fan is a great idea, it lowered my temps 5 - 7 degrees F. Also the sideintake is another great idea. See if u can duct those 2 side intakes to your cpu hs/f. That would be sweet.:p

[maxima88]

I'd install one of those tornados on the side cover to blow onto your vid card to help cool it down. I have 2 fans on my side cover, 1 for my cpu the other for my vid card. Helps keep my temps down and increase my o/c.

[ArBiTaL 24]

Top mounted fans are cool (lol) because that is where the heat gets trapped, when it rises (heat rises you know!:D);)

Seriously, very good idea.

[slater3333uk]

the top fans a good idea

i would strongly recomend that you duct the two in the side panel to your cpu and graphics heatsinks respectivly.

Yep- second that idea:D

[TehMaster]

hey guys. OK, this is messed. I installed both fans, one on side, and one on top. But, the only thing it did was make things a lot freaking noisier!!! My temps didn't change at all. Infact, it might have made things worse by like 2 degrees C. i dont understand. Maybe the top fan is pulling out too much air, like its pulling out the cool air too or something...... i just dont know. Any help?

Thanks, zack

[slater3333uk]

it could just be that more case airflow is not what you need you may need a bigger heatsink or something like that

as for the temp rise it could be that one of your case fans is working against the cpu fan and its depriving it of air check its rpm if its reduced this could be the problem

im feeling my top fan right now.... yup, getting rid of all that hot air.

[Rickster]

TehMaster top blowhole theoritical is good. Why hot air rises to the top and the blowhole exhuast the hot air. The only problem I can think of is that there are too many wires blocking that blowhole on top. A Tornado should work fine. I don't know if im right. Im still new but what I know is that you would probably want to have cold air keep coming in very fast and hot air exhuasting very fast. So to do that create yourself 2 convection systems which you have already did. the front intake is probably to cool your harddisk then the hot air rises to the top blowhole. Then you sidepanel blowhole pushes in cold air and your rear exhaust exhausts them as quickly as possible.
Thats all.
BTW try to clear up the wires first and see your temps. if it doesnt drop then only duct. If your temps drop don't bother to duct.

[Rickster]

BTW dont curse as me! Im still a darn new newbie. I only know though this forums.

[TehMaster]

ok guys....... i think i might try slowing down the top fan cause i think it is drawing out too much air, even some of the cool air that is coming in. I am also going to buy extension cables for all my power cables n such so i can route them around the sides of my case, instead of having them flow through the middle.

Anybody know any good sites that offer cables for cheap?

I found a site called cablestogo.com, which has 14in 5.25 INTERNAL POWER EXTENSION CABLES, which i need atleast 10 of for about... 2.99

amd well, i dont want to spend 30 bucks on some extension cables.

Anwyay, if anybody has any good ideas for me, or knows of any great prices for stuff, let me know.

Thanks

keep that top fan blowing out.... i said the same thing when i put mine on. It just blew out cold air. If you wait a few hours and let things start to settle then it will start to blow out hot air.

Also about those power cables, get some electrical tape. Just this weekend I got some and i wraped all my wires. If your running an AMD mobo then grap those "special" pentium power cables and wrap them togeather. You will never need them. Wrap them tight and stick them behind your power supply or some place where they wont get in any way. Wraping power cables also helps with organization.

Dont wrap your IDE cables. Just buy some round ones. If you wrap them they just look like crap (I guess it doesnt matter what it looks like if you dont have a window). If you have a lot of extra IDE cable then just stick it in a cd rom drive slot.

[UnWishedLegacy]

I think a Tornado for a blowhole may be a bit drastic, you could try using a fan with a lower CFM or perform a 7volt mod on your fan (loads of guides around here)- this may (if its the problem) stop the suction of air into your Heatsink/Fan, and reduce your noise levels.

But ducting is definatly a godo way to go- assuming you have the space avalable in your case.

[TehMaster]

ok, i have already wrapped those extra cables........... and i have a lot of elec tape in my case.......... most wires are taped to the side of the case or something, have all ide cables rounded (total of 4). the extra ide cable is cramed into the extra floppy bay.

But, i still want to get extension cables for all my power cables so i can route them along the sides of my case, and not have them hanging anywhere.

For the fans, even if they run for a few hours, i still see no change in temp when i have the extra two on (side intake and top exaust) and when they are off. My comp runs at about 30 C idle.
I just dont get why they dont make a difference. I would think the top fan would significantly lower temps because it is getting rid of the hot air. The side intake (1 of 2) blows right onto my vid card, but it seems to make no difference.

And last, anybody find good prices or a good site to buy those extension cables from? The only place i have found is www.cablestogo.com

Looking for ideas!!

[orion25]

Maybe put the tornados both as exhaust. That way they will use the cracks in the case to draw more fresh air in and supplement the intake fans. What are the CFM's of your intakes?

[MoonWolf]

Get a cheap fan controller and slow that top fan down. This will allow the cold air being brought into your case by the side blowhole to have some effect before it is vented out.

[TehMaster]

Yeah, i am planning on getting a fan controller. The 2 front intake both have a max of 32CFM, both the rear exaust have a max of 32CFM, and one of the side intakes has a max of 32CFM. The other intake on the side and the top exaust have a max of 119CFM.

The problem is that the 2 bigger 92mm fans (top and side) are both Vantec Tornados. They have 12.5 watts each, so i need a good fan speed controller. So, im going to buy the VANTEC NEXUS NXP 201 to control them.

I do plan to slow down the top fan some. I'm thinking about replacing the 2 fans for other 92mm fans, because they are soooooo damn loud.

Oh, by the way, i have a Swiftech MCX462+ HS with a YS Tech TMD fan (70x70x15mm, 5600rpm, 36CFM) blowing on it.

[Rickster]

Yep wrapping those cables is a good idea. I just used maskin tape.CHEAP! Wonder that will work. I hope it doesnt blow or anything. But i dont think so. Do have the sidepanel fan blowing in. You want constant airflow, and the cracks to let air in might be too little. I wouldnt know

[Genn]

Just a little reminder about tape, it creates a nice stiky residue after you take it up. I know I use it for a while. If that doesn't bother you or you don't plan on changing the interior of your case, go for it, it's cheap and easy.

[WA2]

if case is ok on temp..why install them?

[Dave65]

What ever you do DONT use duct tape,if you ever have to take the tape off it leaves a sticky film on your wires

[[EG]~NaTz~]

dont take anyones oppinions. top exhausts have been known to help if u want the truth go and smoke test ur machine.

[Rickster]

Well thats why i didn't use duct tape. Maskin tape is slightly easier to remove than normal tape. And some arent so sticky thats y i chose them

[husky_ky]

Zip tie's my allie in my campaign againt the evil Dr. High-Case- Temp:cool:

[Rickster]

Some people find zip ties good but personally i don't. Reason being u can't really wrap them as good as tape where tape you can wrap them as if like a rounded ide cable

[Dave65]

I totally agree:D

[husky_ky]

Didn't realise he's talking about IDE cables :rolleyes: i personally just stuff them into empty 5" bays and tie them down:cool:

[Rickster]

Nah I was talking about power supply cables and molex cables. I don't think I wana wrap my IDE cables. Heard they might cause interruption.

[BlueWraith]

Power supply extensions? Bleh... why spend that much on some molex extenders when you can buy 18guage wire (yellow, red, and black) for $5 each for more then enough wire. Just get some heatshrink and solder the connections togeather to expend the leads. As for the mobo power, take some expandable mesh wrapping and some more heatshrink.. looks great. :)

[Rickster]

blowholes are important tehmaster. hotair rises right. so you need that to exhaust that hot air before it goes to the CPU and the CPU will suck in warm air. I dont think it will mess up airflow. your plan will work is just a matter of placing those side intakes
