The internals will be :
CPU: Intel Core i5 4670K
CPU Cooler: Noctua NH-U14S or Prolimatech Megahelms or Prolimatech Armageddon (haven't decided yet:)
MB: Gigabyte GA-Z87X-D3H
RAM: Corsair DDR3 2x4GB 1866MHz CL9 Vengeance Pro
SSD (system): Plextor M5 Pro
HDD (storage): 2TB WD Green
GPU: MSI Radeon R9 270X TwinFrozr
All seem pretty decent, I would chose the U14S over the megahelms and Armageddon out of having a good included fan already, Noctua NF-A15 PWM that can range from 200-1500 rpms, this will depend into how your motherboard can manage it, not paticularly familiar with Gigabyte so my recommendations goes into Asus with FanXpert2 pretty solid software, a little bloated and weird way of reading temps, but its still amazing imo that with chosing the proper fans for each header (CPU_FAN = 4pin PWM, CHA_FAN = 3pin), FanXpert2 on the first tunning will check the fans range and have it operating at their lowest on idle, and provide a suggested curve on load, that you can change to your liking, but this is the easiest way to set it up a very quiet pc (again choosing the correct fans). Now if you are more a minimalist into not wanting extra software to control your fans, and you want pure bios, then look into MSI and Asrock motherboards, pretty good 4pin PWM fan control, but here is little more complex as you will need 4pin PWM fans and depending on the amount of fans you wish to control, a Y PWM splitter. Now if you prefer gigabyte because of whatever reason, try to chose a case that has a built in fan controller as if their fan control is not of your liking or speedfan doesnt recognize the sensors, then you have the fan controller as your fail safe, like Fractal Cases.
1. Should I go with active or semi-passive PSU?
What I'm taking under consideration at the moment?
- Corsair RM850W (SP)
- Fractal Design Newton R3 600W (SP)
- Seasonic X-Series X-650 KM3 (SP/A)
- Be-Quiet Dark Power PRO 10 650W (A)
- Be-Quiet Straight Power E9 680W (A)
I agree with steve, i dont think you need anything over 500W, even a GTX780 can be driven easily with 500W. Not sure whre you are buying it, or if other brands are available, I would consider Kingwin LZP-550
platinum, semi passive. If you cant find kingwin or its too expensive, then i would go with bequiet! Dark Power Pro 10 550W
, If you cant find either, i would go with Seasonic X650
. The RM seems like a nice option also, and reviews are decent for what it costs, but its relatively a new product, so i would go with the before if you can, but if you do go with it, then consider the RM550 or RM450 for cheaper and should power your setup fine with a lot of room still.
2. Will this setup be quieter in silent case (higher temps) or meshed one?
What I'm taking under consideration at the moment?
- Fractal Define R4 (what draws me away: door opens to the left only)
- Corsair Obsidian 550D (what draws me away: front panel. How do I use my DVDdrive while having earphones plugged and 2 USB drives in use?)
- Corsair Carbide 330R (what draws me away: nothing really:)
- Nanoxia Deep Silence 1 (what draws me away: nothing, except it's really, really difficult to get:)
- Fractal Core 3000 (great case, lack of doors is a big +)
- Corsair Graphite 230T (great case, lack of doors is a big +)
- Fractal Design Arc Midi R2 (great case, lack of doors is a big +)
Im going to contradict my self a little here, but bare with me. For me, the most important thing is functionality, if the door is not desired for your or makes your life complicated, then don't go with it, the doors helps a little to dampen noise, but not a big thing either. For building a quiet pc, the most important thing is to chose quiet components, specially since this will give you room later on to chose the most practical case, in my experience cases matter but not as much as people think, a lot believe that a case will silence an already noisy rig and doesn't work like that, at least on my personal testing, even SPCR a lot of not quiet oriented cases end up with editor choice like Silverstone TJ08-E or FT02, they are great cases for aircooling very efficient, and thus allowing the end user to spin down the fans where they are inaudible. What im trying to say is that if you chose your components carefully, then i think you could go with the Fractal Design Arc Midi R2, specially since you are placing big + to all cases without doors. It wont have dampeing as the R4, but you also gain a much easier filter removal, more fans slots in case you decide to increase your fans, etc, the insides are very similar to the R4, and working with it its very nice, has great room for cable management, good placement of grommets holes, decent hdd cages (i dont use them though). Now here is the contradiction, owning both the R4 and Arc Midi R2, i ended up with the R4, i tested both, and were very similar in noise, but i wanted the Arc midi R2 to have tons of fans spinning extremely low, but turn out that my NF-A14 PWM didnt like horizontal + pushing down (made a buzzing motor noise at all rpms), and i don't use opticals anymore, so decide toward the R4 as if im not going to have fans on them might aswell be closed to avoid dust, and to me personally i like more the look of a fridge alike case of the frontal door of the R4.
Additional case fans: Noctula NF-S12A series (PWM, FLX or ULN) or NoiseBlocker Black Silent Pro PLPS.
Just some final comments about the fans you are considering, the NF-S12A is a very nice case fan, but it does suffer on heatsinks or heavily restricted spots, the Arc Midi R2 has a sponge type of filter, not sure how will it perform behind it, its just more a warning than saying its a bad choice. The noiseblocker PLPS is a great fan, i used two for almost 3 years, and it cooled my HR02 and exhaust on my TJ08-E fine. But the only drawback of it, its the design of the PWM will only allow to be drop down to 650rpm, weather this is good enough only you can decide, but a lot of bios have restrictions into % for example my old GENE IV allowed only 20% this meant the fan lowest rpm that could achive on that setup was 900rpms (personally i find it to high for idle state). Other fans including the NF-A12S that you are considering that will drop much lower (around 250rpms) on pure PWM control, or even cheaper alternatives like Nexus Basic 120 that undervolts very well under fanXpert2 or a fan controller.
If you want to go with Noiseblocker and the fan of choice you planned is 3pin, then consider Noiseblocker M12-S1 (or S2 depending on your cooling needs), read the following review, Fan Roundup #6: Scythe, Noiseblocker, Antec, Nexus, Thermalright
Now if the case of your choice ends up being Fractal Arc Midi R2 or Define R4, then also read the following roundups that might help you decide on the 140mm fans,First 140 mm Fan Roundup: Noctua, Phanteks, XigmatekSecond 140 mm Fan Roundup: Antec, bequiet!, Corsair, Scythe
Try to decide if you are going PWM or Voltage control with your fans, then decide the case and the proper fans for each slot depending the motherboard and its limitations.
