This is one of my builds, this time decided to go fanless, after having really good results with air cooling and open cases.
As expected, 100% passive, without any airflow isn't that simple, and while open case works great with slow fans (compared to even very well ventilated conventional case), if you remove airflow entirely, things get pretty warm..
Case: Dimastech BT103 mini
Anyway, results are good enough, I'm using i7 2700k with thermalright hr-22, close to stock clocks (overclocked from 3.9 to 4ghz), with all power saving features turned on. Max load voltage is just 1.1V. Temps in idle: 40-45, normal usage stress (like games), around 60. Full load in occt, not going to try, most likely would hit very high unsafe temps, but I never see such load, in any game, not in for example video processing, so there is no point.
I'm aware that hr-22 isn't best possible fanless cooler, it is also very expensive. Normally I wouldn't buy it, just found a good deal on forums, and that made it worth it.
GPU is msi gaming 750ti, stock clocks with xigmatek bifrost cooler (old cooler, pretty good, got it mainly for the looks, as it is anodized black). There is room for improvements, could lower the voltage in bios, I plan to do that later. With lowering power target, card hits around 60-65C in games that stress it constattly yo 70-80%. Will go higher if you run no v-synch so 100% load all the time, but stays below 80 (about 75), so there is no throttling. From what people say you can lower voltage below stock, and still overclock card past stock clocks, which results in faster and cooler card.
There is one ssd, and one 2,5'' wd blue drive (disabled parking in os). If you put ear next to it, it is audiable, but about 1m away, not. I plan to just place it further away from the case, using esata cable, in wardrobe or closet. Cheaper and more effective solution, than buying overpriced scythe quiet drive or equivalent.
Psu is from my previous build, I'm going to reuse it future, so ignore the overkill wattage. It never turns on fan in this system, as it wasn't in heavy oc i7 + gtx680 + advanced watercooling system. Fan turns on at around 80% load, so it isn't easy to do with any single core card (unless mining with 290 i guess).
What is important, there is no coil whine. Psu, mobo and gpu, even under load, silent as rock, no buzzing. Which makes me happy, because so far every single graphic card (especially higher end models) were producing coil noises under load.
