Fan Location in Arc midi R2 - Page 3

post #21 of 42
Thread Starter 
Thank you sir. I was reading another thread you had on the subject yesterday. I showed the boy both cases and asked him which one he liked. I think he picked the r4 because it had 4 USB ports. Didn't tell him what it's for though. Will be picking up the rest of the parts in 2 weeks. I did see today how to put para cord on the wires. Looks pretty good.

Well that 8 way splitter looks like it would make things easy. Plug the aircooler in ch1 and all the other fans on the splitter.

8-way hub or a couple 4-way splitters as shown. The splitter can be daisy-chained to give 7 on one PWM header. All the cabling fits behind motherboard so not an issue. Hub needs more depth than splitter.

I keep thinking about para-cord but when I think about all the work involved I chicken out. biggrin.gif

FYI
Velcro cable tie in bulk is super cheap and can be used on everything. I use 10mm width in computer, 16mm-25mm for extension cables, garden hoses, etc. Cut off a piece the length needed to secure whatever... and being Velcro it's reusable. biggrin.gif

Looks like a lot of people are sold out of the 8 way. If I went with a couple 4 ways, would one go on cpu fan and the other on cpu opt? The one on cpu fan would have the cooler I'm guessing.

Let you know if we try the cord. Just need to get a tool to remove the ends.

Yes, CPU opt is like a Y splitter for CPU fan.. uses same PWM control signal. Or if you only want one lead from motherboard going into back you can plug the 2nd 4-way splitter into first. As long as one of CPU fans is plugged into splitter CPU socket (4 wire socket with RPM lead) motherboard can read rpm.

I'm not sure motherboard actually uses rpm. I think the PWM signal speed is based on percentage and not on actual rpm... In the same way voltage control only changes voltage. The rpm is for us, not motherboard.

Sunbeam Universal Molex Pin Remover Kit looks good, but I really don't know.

I saw a tutorial somewhere that did not use heatshrink, just heat / melt the para-cord and roll it with finger onto pin.

Doyll, ordered one of these today, http://www.frozencpu.com/products/20988/ele-1196/Swiftech_8-Way_PWM_Cable_Splitter_-_SATA_Power_8W-PWM-SPL-ST.html. Looks like they changed the power connector. I started to change to a fan controller, which I really liked, but think this will be the best route for my son. Ordered the D-14 and a NF-F12 pwm and Nf-A15 pwm to replace the stock fans. Also ordered some NF-A14 pwm's for the case. Hope I got the right fans, if not, that's what they'll be because my ocd on going over all this is about to make my head exploded. Think we will be skipping the para-cord for now. He likes the closed case instead of the window. Probably bug you again when I need to set the parameters up on these fans.

Thanks for letting me know how it's going. thumb.gif

They make the hub both ways. Don't think it makes much difference.
NH-A14 PWM are very good fans. A little pricey, but very good.

FYI,
Could have ordered the NH-D14 2011SE (has PWM fans) and a universal mounting kit NM-i115X and saved a few dollars.

Well all I need is the case. I have the R4 and Arc Midi R2 with window panel at stores nearby. I keep reading the airflow is better on the Arc R2, but how much better? My son wants the 4 usb ports up front, but now I think he likes the look of the solid side Arc R2 better. If the Arc R2 is that much better on air cooling, I'm going to have to hurry up an order one. I have 5 Noctua NF-A14's to replace and add to the case. I guess I could order a usb hub, but to get the potential of true 3.0 would it need to wire off some sort of card since the case ports use my one 3.0 mobo header?

Would you try these fans with LNA adapters on first or see how loud it is without?

Also, am I safe on power requirements for these fans? I don't recall seeing a power rating on the splitter like I have on fan controllers.

Thanks in advance.

If you want an in-depth review of both the define r4 and arc midi r2, here are links to OC3D's videos on them:
Define R4: https://www.youtube.com/watch?v=_NM81822_ag&list=PLBDE3358367DB7324&index=22
Arc Midi R2: https://www.youtube.com/watch?v=SVqFb2eKN_4

I personally own the Arc Midi R2 and I really like it. My specs are Folding/BOINC rig in my sig. Airflow in this case is excellent; I removed the top hard drive cage and kept the stock fans. In the front I added a Cougar Turbine fan (for context: http://www.newegg.com/Product/Product.aspx?Item=N82E16835553009) in the bottom slot (I have two hard drives in the bottom HDD cage). I also run my power supply with the fan up which has not affected my temps on anything else at all. I have all the case fans (three stock Fractal fans + 1 Cougar Turbine fan) connected to the Arc Midi's fan controller, which I keep at the 7volt setting all the time. I also run the fans on my Corsair A70 (stock fans) with their included resistors and they are plugged into the cpu fan connection of the motherboard, but they aren't pwm fans (aka constant rpm).

I just wanted to include my 2cents.gif on your cooling situation: you don't need to have your fans constantly changing their rpm setting. It is possible to have a cool system that has a nice balance between noise level and cooling performance. My computer is nearly silent and the only noise I really hear from it is a very low and consistent hum, which I personally find soothing.

For context, my computer is running BOINC and Folding@home 24/7 unless I am playing games or doing maintenace so it never gets a break from me or heat. My gpu never goes over 65 celsius, my processor hovers around 50 to 55 celsius (there are other non-related factors that result in my cpu being a little warmer than I'd like).

EDIT: I might have either the back or top stock case fan connected to a motherboard fan header (also not PWM) due to the Arc Midi's fan controller only having 3 connectors and I don't have any splitter cables.

I have no problems with supplied USB headers. That's using webcam, mouse, keyboard, HTPC remote, 3TB HDD, as well as USB sticks. Maybe someone with more USB experience will jump in here.

Yes, on all motherboards I know of both the CPU fan and CPU opt use same PWM signal.

I would set up the system with all fans speed controlled by motherboard. Possibly GPU too if it's high heat / power consumption, but usually when GPU is working the CPU is too.

As Genesis said, fans don't have to be variable speed based on system load / heat. To me it's only common sense to do it. Notebook / laptops do, CPU coolers do, GPUs do, CLCs do, custom loops do, cars, truck, motercycles, etc. all do too. So why not the case fans too?
