Fan Location in Arc midi R2

post #1 of 42
Thread Starter 
Not sure if I should have put this here or the case section, but here it is.I tried to go water cooling, but just can't over that hump yet. Trying to build my son a machine that will last a couple years as he goes off to college. His birthday is at the end of next month and we will build it together, so I need to finish getting the parts. He currently has a core duo that is getting tired. He's into gaming, usually on team speak or Skype and watching youtube at the same time. Lately he has done a little video editing from the gopro, but that was done on my machine. Unless I need a bigger case, I've narrowed to the Fractal Arc R2 midi and R4. My goal is to possibly overclock to 4.2 with air cooling. The current build is as follows:

I7 4770K (already purchased)
Asus Hero Mobo (already purchased)
Noctua D14
G-Skill Trident X 2133 16G
Samsung 840 ssd 128 (already have)
WD Caviar Blue 1Tb (already have)
Possibly another 7200 hard drive
Evga GTX 780 acx cooler or ASUS Gtx 780 or MSI
Cooler Master V850 850 watt power supply (already purchased)

I've used a pic of an R2 midi and plan on removing the center bays. I've put several options as to fans and flow. The ssd will go on the cable side of the case, unless that is a bad idea. So now the questions.

R2fansproposal_zps7a50b7eb.jpg

Does the hd cage on the bottom hurt the effort of fan #1?

If I have only one hd, can I remove the bottom cage and mount it to the floor? If I add two, can one be on the floor and one in the bay below the cd drive or just stick both in the lower cage?

If I can get the graphics card to go in top slot without problems from the d14, I planned to remove the remaining card plugs on the back and mount and external fan for more rear exhaust. (Red fan 3 in pic). Would this be needed?

Would fan #2 and #4 both be beneficial, just one or none?

Are the factory fans any good or should I replace them?

Most importantly, if all these fans look good, what the best way to hook them all up?

Thank you for putting up with my noob questions as I have never oc'ed and never put this much thought into air flow on a build, since I've only built 1 machine since the P3 1 gig.

Almost forgot, would there be a need for a fan on the side of the case or leave it shut?

Thanks again in advance.

Midi R2 is perfect fit for all. Just get the one with the window.
As my system, the bottom HDD do not affect the airflow. Just remove the plastic sliders on the HDD cage.
Stock fans are good, not super strong, not super loud. But will work. All you need is to get airflow through the case. I run my fans at 30% (400 rpm), and temps are fine on a OC 3770k.

Both Arch Midi R2 and Define R4 are very good cases.
  • Of course the HDD cage affects airflow from fan 1.
  • Yes, on the floor or on bottom of optical bay cage.
  • Mounting graphics card in the middle area with PCI slot covers removed it might work better. With HDD cages removes and bottom fan there will be plenty of airflow to graphics card intakes. The heat will move up. Buy 3 good fans like Phanteks PH-F140HP PWM or PH-F140XP for front and bottom intakes.
  • Problem with NH-D14 is it does not have PWM fans. Only the NH-D14 2011SE has PWM fans. All Cryorig. Thermalright, Phanteks, coolers have PWM fans.
  • Factory fans are pretty weak. I always use cooler / radiator fans for case because the grill, filter, cables, etc. create resistance similar to a cooler. Use fans above to replace front and bottom fans with PWM fans you can use motherboard and even graphics card PWM control for case fans. The advantage is case fans only speed up as components need more air to cool instead of running fast making noise all the time so they supply needed air when components it..
  • I would not use that many fans. I've done several Defines with 3 intakes and one rear
  • (or not) exhaust with very good results. For example my sig rig idles 700rpm @ 24-28c CPU; 1000rpm @ 28-30c GPU. Full load 950-1050rpm @ 43-48c CPU; 1300-1800rpm @ 45-55c GPU. I can just about hear case & CPU fans and GPU fans are a little louder it at full load. Air temps inside of case are a couple degrees above room temp. You might find the links in my sig helpful.

Thanks guys. Do you see in any pros or cons between the r2 and r4, or is just personal preference?

Doyll, do you lose noticeable graphics performance with the card being in the second slot? You already answered a question I thought of this morning in that it is better to control the case fans with the mobo. By adding two fronts and one bottom, what kind of connectors do I need to get everything to work off the mobo? Please pardon my lack of knowledge here, but the first comp I built had one fan and the second was on an antec 300 illusion that had a bunch of fans already installed.

Thanks again.

Depends on motherboard and what the different PCI-E slot spec is. Honestly I haven't had any problems with cooling regardless of position. As long as intake supply cool air to cooler intakes and heated cooler exhaust is pushed / pulled out of case all is fine.

Arc Midi R2 and Define R4 are very similar. R4 is probably a little quieter with sound deadening and door in front of fans, but using PWM control on case fans means the only times they run fast enough to be heard is when gaming, number crunching when system is working real hard.

Oh, I raise case up so bottom gets better airflow. Quiets down bottom fan too. wink.gif

Thanks. The diagram in the manual says the top slot is PCIE _X16X8_1 and the second slot shows PCIE_X8_2. Then in the box below it says slot 1 is PCIE 3.0/2.0x16/x8_1 slot and the second shows PCIE 3.0/2.0x16/x8_2 slot. On the next page it recommends that a single vga card go in PCIE _X16X8_1. So I'm guessing the first slot is the best, or am I missing something? Thanks again for your help.

"Build it and it will be cool." biggrin.gif

As long as CPU and GPU get cool air to their intakes everything will be cool. My GTX580DCUII runs nice and cool in top slot. I moved it down and put my Xonar D2X in the top and temps are the same... well close enough I don't notice any difference.. maybe 1c.

Mate in Ireland has this one


Mine now with back vent removed and duct from cooler to back


Modified Define R2 with TY-140 fans and Silverstone filters.

Very nice. Do find the ducting to be more efficient? What is the duct made of? Guess I'll start off basic, by swapping out the case fans and add a front and bottom and see what I get. Can always add more if needed.

Thanks again.

BTW, I see commodore 64 under your name. I still have mine and the enormous floppy drive, both in their original boxes right next to the Atari 2600 in the box.

IMO, Fan #1: pwm 140mm, Fan #2 pwm 140mm, and a 140mm rear exhaust. All connected to PWM mobo headers. No top fan, no side, imo. That's what I'm running on my Arc Midi at the moment, with all three case fans running under 800rpm and temps are fine.

@doyll: nice fans =) I really like Thermalright's 140mms. If you ever get the itch for new ones, I highly recommend the TY-141. Much improved over the TY-140, imo, and the best of their 140mm lineup.
