This isn't what I had originally intended, and I plan to continue working with with it. I'd like to thank SPCR for its words of advice and especially its reviews.
First I had intended to build a custom case, and that has yet to occur. I was hoping for something pretty open air.
Second, this is just the first OS install and operation of the PC. I haven't gone and stress tested it yet, or really done anything too rigorous. It plays Team Fortress 2, which represents about the level of stress I want to achieve. I plan to underclock and undervolt the PC to reduce power consumption as need dictates. (I could use advice here.)
Third, I haven't added a video card yet, but I'm planning to add an ASUS GTX 750 fanless. The Stock processor GPU works, but can't quite cut it for my tastes.http://www.maximumpc.com/asus-pairs-gef ... oler-2014/
Third, I'm exceedingly happy with how quiet the stock 180mm case fan is. Its quiet, and it works. Why bother doing more work...
Powersupply: Seasonic X-400 Power Supplyhttp://www.seasonicusa.com/NEW_X-series_Fanless.htm
Case: Silverstone Temjin TJ08 Evolution Micro-ATX Casehttp://www.silverstonetek.com/product.php?pid=303
Motherboard: ASUS H97I Plus https://www.asus.com/ca-en/Motherboards/H97IPLUS/
Processor: Intel i3-4160http://ark.intel.com/products/77488/Int ... e-3_60-GHz
CPU Cooler: CR-80ehhttp://www.nofancomputer.com/eng/products/CR-80EH.php
SSD: Kingstone SSDNow M.2 SATA III SSD, Type 2280, 240GBhttp://www.kingston.com/en/ssd/s
RAM: Corsair - Vengeance LP 16GB DDR3 1600MHz CL10 Dual Channel Kit (2 x 8GB)
The M2 SSD drive reduces wiring and cleans up the potential mess in the case. (Not that I'm a tidy person or anything.)
The Temjin Case works wonders with the power supply. Its able to passively radiate heat without any issues. In fact I would have preferred a cheaper simpler smaller case, but I was very concerned about how well the power supply would get ventilated. This case is about double the volume of what I'd prefer. But for you other folks other there... there's tons of space for bigger cheaper motherboards.
I originally built all this with stock CPU fan, and case fan attached just to make sure I could make it work. I then replaced the stock CPU fan with the NoFan, and whoosh.... silence. The case fan is exceedingly quiet, and I really don't mind leaving it attached. Its also PWM controlled, so not an issue to work with.
With case fan the PC idles at 35C, going up to 40C with heaving internet browsing and use. With playing Team Fortress 2 for hours and hours the CPU temp hits 55C. Again, its dead quiet. With PWM control, the case fan moved up from 300RPM to 550RPM. Fanless, the temps were 39C and 65C.
The CPU is not overclocked, but is running with Intel Speed Step. My preference is to have the PC operate at a lower clock frequency continuously and perhaps maybe allow Intel Speed Step after that.
I also need to add a graphics card. On one hand I expect it to offload some heat from the CPU, but on the other hand, I expect a better graphics card with generate a higher frame rate which will drive CPU heat.
The next thing I plan to do is start some reasonable stress testing and hopefully learn how to underclock undervolt the CPU.
Anyways... thanks to the site operators for all their efforts.
