THOSE fans definitely aren't going to get anywhere near that.
1) Restriction.
2) they're bitfenix fans, 'nuff said.


And no, I don't think you need to do much better since the top fan is to cool the VRMs

Ok, thank you for your advice.
post #293 of 2323
hi dave, i have been reading this with great interest.

i am building a custom case with 4 inlets, 2 each side of the case and a 4 fan push pull config with my AIO cooling on a 240 rad, what i would like to know is, i purchased 4 noctua nf s12b FLX and 4 nf s12b ULN (yes i know you dont rate the noctua's highly). the FLX have a top speed of 1200 RPM with an airflow of 100,6 m³/h, against the ULN 700 RPM and an airflow of 56,9 m³/h. which would you recommend for intakes and exhausts. i was thinking the faster flx's for the intakes going with what you are saying about increased airflow and better sp and using the lower rated ULN's for the rad on a push pull.

I really have no idea why you bought noctuas. Buy Gentle Typhoons, the FLXs barely have enough static pressure to make it through a filter

Why doesn't anyone listen and buy proper fans?

hey Dave what case cooling setup do your recommend for the Silverstone Raven RV03 case?

I currently have the following setup.

1. two 180mm penetrators that came with the case as bottom intake
2. two enermax t.b. silent fans as intake (near the CPU cooler
3. a 120mm Scythe KAMA FLOW2 as read intake
4. the original silverstone 120mm top exhaust fan

plus, the CPU cooler: silver arrow extreme as pull pull.

here is the case, if you are not familiar with it.
http://www.silverstonetek.com/raven/products/index.php?model=rv03&area=en

i current don:t have the optical drive and the hard drive cages installed. i heard that having them allows air from the front intake fans to be easily channels towards the CPU cooler.

I'm about to get the last few parts for my PC below tomorrow I haven't built a PC in a long long time (AGP, IDE Single Core) and I was having a bit of a last minute panic about the source video I was watching to get my advice https://www.youtube.com/watch?v=cUzdNcZeM-s at 1:07:55

(http://uk.pcpartpicker.com/p/2WLLK)

Intel Core i7-4770K
Noctua NH-U14S
Asus Z87-PRO
G.Skill Ripjaws X DDR3-1866
Sandisk Ultra Plus 64GB
2x Seagate Barracuda 2TB 7200RPM
1x Samsung Spinpoint 1TB
2x Sapphire Tri-x R9 290
BitFenix Ghost
5x BitFenix Spectre Pro LED 56.2 CFM 120mm Fan
Corsair RM 850W
DVD-RW

Question 1

I was wondering how to set up my fan for intakes and exhausts, I made a quick and dirty JPEG of the layout, including a third HDD that i already had around.

http://imgur.com/RcdsxtZ

I numbered them all so you could say for example 1 - Intake 2 - Intake 3 Exhaust ect, there are six extra fans in total, five of them are Bitfenix Spectre PRO's and the 6th one is that fan that you can see at point number three, the Spectre PRO's are actually going to be number one through five and the "free" fan that came with the case will be moved to number six.

Room gets a -little- dusty, but not incredibly dusty in case that makes a difference, I don't really like dust in my case as I'm very forgetful to clear it out, but if its going to cost me a lot in temperature then I'd rather get used to cleaning a case than have bad temps in summer.

I'm not even sure if i have enough fan connectors on the motherboard to plug in the 6th one

Question 2

Can the CPU cooler be orientated in any direction? and if so should it be up towards fan 1&2 or back towards fan 3?

outside of the intakes and outtakes questions I am a bit worried about the first R9 290 blowing hot air over the second R9 290 but there doesn't seem to be anything I can do about that or is there?...

Questions 3

Can the PSU be turned upside down the receive the hot air from the bottom graphics card and then vent it out of the back of the case (where there otherwise isn't an exit) or is that a bad idea / impossible?

One of the reason why i was asking these questions was because I was following along with this Asus NA building a Haswell PC video https://www.youtube.com/watch?v=cUzdNcZeM-s and at 1:07:55 he starts explaining how he will have fan 1&2 as intake fans and the people in the comments were saying that it was complete madness and that 1&2 should be exhausts without a doubt but then there is part of your guide that says you could have all intakes except one exhaust and I wasn't sure again

Thanks in advance with replies. (and apologies in advanced for not going with the fans you would suggest as I was taking the video as gods truth up until the last second I was about to build it, he gets 4.8ghz overclock and -says- it stable with this exact cooling but its more than likely staged and pre-binned tongue.gif)

The NH-U14S might work in both orientations. There's no problem with the physics in the heat-pipes or the base or whatever. Regarding the outer part of the cooler's fins, those are cut off at the bottom, so might not hang over your memory sticks (you chose RAM with large heat-sinks). It's overall probably always best to orient the cooler to blow towards the rear.

The "Fan 2." position in your sketch used as exhaust can steal the fresh air that comes from the bottom front intake fans and make the cooling in the case worse.

Silverstone once built a case where there was intake at those top "1." and "2." positions and it worked great. I'd experiment with that just to satisfy curiosity even if it seems stupid. With that much intake (Fan 1+2+4+5 positions), you could remove the slot covers for all the unused PCI slots next to your graphics cards and that could turn out great.

Here's a demonstration video about that 2008 case with the top intake: https://www.youtube.com/watch?v=Qe-2ZqmSGug

It obviously can work pretty great so those Youtube comments you mentioned were probably just short-sighted.

Alright thank you, i'll do fan 1-2 and 4-5 as intake and 3 as exhaust, instead of leaving the PCI slots completely open, hot about something like this just for piece of mind? http://www.quietpc.com/gel-pci-brackets seems to be dust filtered PCI covers, The video was pretty interesting as well!

I'm worried about fan 6 (if there is enough ports on the motherboard to plug it in) I was thinking Intake but the second graphics card will be pushing hot air down towards it which conflicts, but if i make it an exhaust then it might steal cool air from 4 and 5

Thank you. I took a read and it's very interesting.

Ugh, I can't barely feel airflow from my bitfenix front intakes, I'm thinking about replacing them with:

Phanteks PH-F140HP/TS
Cougar CF-V14HB
Corsair AF140-CO

Which would you recommend for better airflow?
