Air-Cooling Advice

post #1 of 120
Thread Starter 
Hello!

I'm planning a new PC build and I'd like to go with "high end" air cooling using Noctua fans and a "Corsair Obsidian 750D Airflow Edition" case.

It'll probably look like this:


So that's 7 case fans:
2x 140mm front (intake)
2x 140mm top (exhaust)
1x 140m back (exhaust)
2x 120mm bottom (intake?)

The fans I'm going to use are the Noctua 4-pin PWM fans with up to 3000rpm.

I'm also going to buy this card reader:


That's the "DeLOCK USB 3.0 Card Reader 5 Slot + 4 Port USB 3.0 Hub" or "DeLock 91494" for short.
What I like the most is that is has a build-in fan controller! redface.gif

It has the following internal connectors:
" internal:
2 x USB 3.0 Type-A male
1 x 4 pin power connector
1 x 3 pin fan pin header male"
You can get more information about this card reader here.

I guess the question is clear now. How exactly... do I hook up my 7 fans on that thing? I only know that I'll probably need a fan hub or something.

Can you help me out? Please?

That device has no temperature sensor. You will have to set all your fan speeds manually and then, if you want more or less cooling, change them.manually.
And since it has only one fan header there is no way to run different fans at different speeds - all the fans will run at the speed that is set.

I see no specification about how much power the fan header can supply, so there's no way to tell how many fans it will support.

Also, there is no PWM control for fan speed, it's just voltage control, so 4 pin PWM fans would be a waste.

I'd steer clear of any product where the manufacturer doesn't supply enough information for you to make an intelligent purchase decision. - they're usually hiding some shortfall in the product.

I suggest you take a loo at Phanteks and Fractal Design cases They are much much better than Corsair cases.

You are confusing lots of fan with good case airflow. While we need more case airflow than components, we do not need 2 or 3 times as much. What we want is for the case airflow to flow cool air to all components. This means case airflow has to flow all the heated air coming off of components out of case without it mixing with and heating up the cool air being supplied to them.

You might find "Ways to Better Cooling" link in my sig helpful. 1st post is index, click on topics to see them. 5th is a good place to start.

If by "high end air cooled" you mean no liquid cooling, then you certainly don't need that many fans. More fans just = more noise, no matter how good the fans are. The picture you posted shows a configuration of putting a radiator in the top. That means the two fans at the top are not really there just to be case fans, they're there to cool the CPU. If you choose a high end air CPU cooler, you'll want the fan(s) attached to that instead of the case. The bottom intake usually isn't practical either, nor is it necessary. For case fans with air cooled components, all you really need is 2 intake in the front and one exhaust in the upper back.

When air cooling top exhaust usually pulls GPU heated air up around CPU cooler .. meaning higher CPU temps.

Bottom intake often improves GPU temps because of how GPU coolers dump hot air in all directions .. their airflow is out top of GPU, both ends of GPU, and toward motherboard .. meaning their heated air is contaminating cool intake air in all directions. The least contaminated and direct line for cool air to come from is bottom .. at least in tower cases. tongue.gif

But bottom intakes a often limited by the airlfow area between case bottom and what case sets on.

My 15170600000 of ancien "second" zimbabwean dollar, as for july 2008 : why noctua industrial 3000 PWM fans?

You might get as good cooling efficiency with "normal" noctua F-series PWM fans, or anything else @Doyll and co would recommend, and those would be cheaper and far, far quieter. Those Industrial models were made, well, for industrial purpose, but Noctua started to sell the to the general public for watercooling-and-deaf builders who wanted insane results on high-FPI radiators, at the price of, well, hear-deafening.

Follow @doyll's and @adamjp's advices ; if you want to keep your case, two fans on the front and one on the end should be enough with the airflow edition ; plug them on your motherboard-controled PWM headers and try to tweak them in the UEFI, if you don't have any software control.


By the way, what are your CPU cooler and your motherboard?

hi yea id go 2 separate units like an aero touch screen 2100 it has 5 fan controls setting on temps max and min and 5 temp sensors i have 1 of these and also got 7 fans atm the card reader i got has controls for 2 fans so voila but its only got 1 temp sensor and has a constant digit of it...both these items own me like $45 as i hunt the buy/sells and ebay and gumtree ..good luck..and a separate card reader that is also good im using a dark rock pro 3 witch is a gr8 air cooler

My problem wiht a fan control system like RustyNailed is using is it's all manual control. I used to like manual control, but I've learned how much easier it is to have all fans controlled automatically .. just like CPU and GPU cooler fans are. Once the temp to rpm curves are setup there is noting to do but use the system. Maybe if it gets really hot outside I might have to adjust the curves a little, but that is a whole lot easier than having to remember to turn up or turn down the fans manually.

I'm lazy and only what to 'set it and forget it'. tongue.gif

What were we talking about anyway? biggrin.gif

i do agree with doyll on my asus z97-a i ldid same ,let mobo do it after all is set up it runs it self for sure....but there's something about these touch screen controllers well its aesthetics lol they look good smile.gif

LOL. thumb.gif
Controll fans with motherboard and use the 'fan controller' in 5.25 bays to play with. Can always use the temp warning to let you know if something is getting too warm. biggrin.gif
