Fan noob needs help...

post #1 of 6
Thread Starter 
Ok, so I have an Antec DF-85 case (scroll down for sum up)

- 2 x top 140mm fans
- 2 x rear 120mm fans
- 3 x front 120mm fans (2 of mine are damaged, so decided this would be a good time to change some fans, well mostly all )

The front and back fans (total 5, 120mm fans) are the ones I really want to replace, the noise and vibration of the fans have been bothering me even at the lowest rpms, the (Antec Tri cools) http://www.antec.com/Believe_it/product.php?id=ODE5


Been reading these threads and perosnally decided that the Scythe gentle typhoons should help make a difference, the only thing that is so confusing is deciding on what ones would really make a difference. Lot of options...and I am a noob when it comes to this stuff, but seems easy enough to do. The forums have sparkd a dark, hidden OCD within me haha.

I was also wanting to replace the stock fans on the Noctua NH-D14 (the 140/120 in p/p), also with typhoons.



The way the case is set up the exhaust fan right behind the noctua is 2.5 inches away. So I was thinking just use a higher rpm version such as the 3000rpm typhoon when it's released should be able to keep up with w/e I put on the noctua...

From what I understand it doesnt really matter how much the intake fans are taking in so it woud be safe to assume the the AP-14's / AP 15's would be fine for that? or should I go with lower rpms. No I do not have a fan controller also another fun thing the 1st fan from the noctua is ~10.5 inches from the 1st top intake fan, and a few inches off from being centered, and a hot swap thing interfering with air flow a little. Same thing with the second intake fan for the gpu, and the third is just on the bottom where my ssd/hdd are with a bunch of unused PSU wires so w/e can really go there. Oh and all 3 do have air filters!

So first two I am thinking maybe an air predator since they would concetrate more of the air flow towards the Heat sink and the GPU? Though I really can't find much relevant information on the air predators. Probably be more than ok with w/e typhoons.

Help would be appreciate. I know I suck and should read more but im just lost in this whirling world of fans.

Oh currently everything is at stock settings, and the tri cool fans are at lowest setting with their own controllers...getting about 28-30c idle and 38c under load. room is kind of cold 65ish F.


attatched a pic with fan locations and sorry for the bad wiring setup really no clue what to do with the bottom wires not like I can hide them any where else silly psu hehe.

More useless info when I do get this all set up, will use NEXUS Silicon Fan Mounts, and my friend said he could get me some spare acoustic sound dampening stuff I could line the comp with.

SO basically will typhoons be sufficent enough to replace the 120mm Fan? and suggested models, to go inside DF-85 / Noctua NH-D14.

Read ehumes big fan guide pretty pro stuff made me want to register here =) 1st post muahahaha look forward to joining the community! and trying to be active

Also sorry if im asking stupid questions -.- it's like im learning to speak a new language. I know these fans will work just not sure if im going over kill...or even sure where to place certain rpm fans gah

think I covered everything i wanted to ask...Thanks if you managed to read this, or even understand it!!

I figure this:

Front and side be intake.

Rear and top be exhaust.


Intake fans should have higher CFM and good static pressure.

Exhaust can have lower CFM and doesn't really need a high pressure.


- as what I have been reading in here.


I will myself be having Sharkoon SystemFan-P's 120/140mm for intake. They have a high CFM.

Exhaust would be a mix of the Corsair H50 stock fan and my CM 690 II Adv. stock 140mm fan. Their CFM is at about 60, and it's good.

Then I'll have a 80x15mm SilenX fan on the right side too.

On my H50, I will be placing two Noctua NF-P12's in Push/Pull...


I don't know if it helps you, but the whole intake/exhaust thing helped me

When I gave my daughter a choice of all the fans I had for the front of her case, she chose the Gentle Typhoon AP-12 - 800 rpm and very quiet yet pushes air. Scythe is not ordering them any more, so the current stock is the last. Runner-up was the Yate Loon D12SL-12 (low speed, available with LED's).

Currently my D14 is in the basement waiting for fan testing, but it is still wearing what I consider the fans of choice for it: two AP-14's with a TY-140 in the middle. I ran it for months at full throttle with the NF-P14 in the middle. The noise was actually pleasant, even though the case is only a half meter from my ear. BTW - with only 20 inches between me and the front fan, I too use an AP-12 for front intake.

For the top of your case I would recommend blocking off the rear fan position and putting an AP-14 in the forward position as an intake to feed cool air to your D14. Here's what my own setup looks like:



With three 120's in front you will have a better setup than I could ever have. Your case is the first Antec case that natively has good airflow, IMO.

Have fun with it. Go with the GT's. Your ideas are right on.

=) Sounds like it will keep things frosty and silent.


Ehume: Thanks for confirming what I was thinking of...Placed an order -.-

Scythe Gentle Typhoon 120mm x 25mm Fan - 1850 RPM x4
Three for intake, 1 for noctua front =)


Scythe KAMA-FLEX 135mm x 25mm Fan - 800 RPM x2
Going to use these for the top fans...Though I will experiment with your idea and try to use just 1 for top front intake and try to block the back one. What would you recommend to block it off Duct tape and cardboard ^^?


Scythe Kaze Maru 2 Slip Stream 140mm x 25mm Fan 1200rpm x1
Going to replace the middle noctua fan with this one, and probably mount the 140mm noctua to side intake.

Only sad thing need to wait for the 3000rpm fans to come out...So till then the 2 antec fans will run at full speed.

Side note...was reading your stuff about shrouds. Had an old logysis fan laying around gutted it and attatched it to the front noctua...I have to say it was a pain in the butt getting the fan clips off and putting them back on, looks ghetto right now (See attatchment) and bent some fins but fixed that right up. Orderd some 25mm meghalem clips, they look a bit easier to use. Even though it isnt exactly straight there is a slight performance increase of about 1-3c, might just be my ambients.

Will give an update when I get the fans in and installed. First build ever, aand I have to say it's fun messing around with it. Though I havent even opend up the case again to see how much fun I will have with wiring. Just wait till I have to do it.

This may sound stupid also but I found an old movie case holder, big and wooden I think I can fit my computer in there. Gonna go explore that option and mod the crap out of it soon as I have some extra cash. A case within a case and foam lots of foam.

Also white, that is the air flow i have right now minus side intake.

That's gonna be loud for the front. I find even the AP-13 a tad loud for my taste. But we pays our money and we takes our choices.

Good. You can report back here on how well they do. It's a fan I know nothing about.

I went to a hobby store and bought a sheet of construction plastic. I spray painted it black:
