If your fan draws 160ma at 12v, that means it's a 75 ohm resistance. If you add a 50 ohm resistor in front of the fan, it'll give you 8v at the fan, and should only dissipate 1/2w, but keep in mind the resistor does get warm. To be safe, I'd recommend you use two 1w resistors in parallel, meaning you need a rating of 100 ohms.

I never got speedfan to work properly on my Z400 mobo. I ended up just using a Low Noise Adapter and some Be Quiet fans, but it gives a "Low-power CPU heatsink for High-power CPU" error at boot with any of the useful processors. The solution is to ground the fifth pin on the CPU fan connector, otherwise you have to press F1 to finish POSTing every time.

My mom's laptop has Windows 10 on an 80GB drive, and with 6GB of pictures, documents, and literally half a dozen other programs installed(VLC, Firefox, Chrome, Office, Minecraft), there's still 40.7GB of reported free space on the drive. I imagine the 32GB eMMC x86 laptops are running the same version of Windows as everyone else.

It'd be much much cheaper to just build two systems...

The Steamlink might be a good solution for this depending on how serious you are about the experience. Then you don't even have to run the laptop, but you do have to have a keyboard, mouse, screen, controller where you want to use it. The laptop is more portable, but higher latency. I'd definitely try to get the laptop plugged in ethernet if you're going to be doing this frequently. You can use Remote Desktop to log into the pc and start Steam in-home streaming. You'll have to add your non steam games to Steam if you want to play them though.

Dirt 4 is not as good as Dirt Rally

144 MILLION hz? Nice.

The Honor 6X is a whole cm taller than the Redmi, and 3mm wider, hardly a phablet... though it does have more than a cm more screen price. I'd say get the 3gb version based on the chip. 4gb isn't needed if you're more worried about price than getting a good SoC

If you're just asking about a budget rig to replace the G4400 dual core, get a Ryzen 3 with motherboard and RAM that you can upgrade the CPU on for years to come as you upgrade GPU. The i3's make absolutely zero sense to purchase now. If you don't like RAM prices then pick up some used i5 and motherboard that'll fit your RAM, and sell your G4400 and ECS board. If you're going to put a Kaby Lake seventh gen processor like the G4560 in that board, you're going to need to make sure you've done the BIOS updates, otherwise it won't even boot. The G4560 has no sensible upgrade path, given price to performance and core count of the newer chips. A 7700k will be fine for a couple of years, but for the same price a Ryzen 7 chip will be relevant(and upgradable) for much longer. Again, this all depends on what games you want to play, and the experience you want from them. The G4560 will bottleneck the 1060 on CPU intensive games at 1080p, and especially if you want to be doing anything in the background while gaming. HOWEVER, you can just turn everything to Ultra and enjoy the eye candy if you're not worried about competitive framerates, and it'll still be much better than a 960 and G4400.

It depends on what you want, but just based on the half of a sentence that you gave us to work with, I would say Project Cars 2. Forza Horizon physics and FFB are awful compared to Project Cars 2, iracing, assetto corsa, raceroom racing experience, rfactor 2, automobilista, GTR, Race 07, Live for Speed, RBR, etc. I don't know how anyone that's played Forza Horizon can recommend it on physics unless they've literally never played anything else. That said, if you're more worried about car tuning and customization, and fun racing as opposed to a more simulation style physics engine, it's probably the only PC game that does all those things well. Dirt:Rally is much better than Dirt 3 or Dirt 4. OP didn't say anything about customization, multiplayer preferences, what input device he has to use, whether or not he needs VR support for now or in the future, and whether he's looking for a RACING game, a GAME where racing is the main content, or a simulator where you can find a league or start your own with friends, or even something where he wants to have serious racing that's easy to jump into. All of this would help narrow down the recommendations. As seen by the recommendations so far, no one has any idea which direction you're looking to go in. Need For Speed would not even be on the list if graphics and physics were the most important criteria for me...

the W3680 is overclockable with the Intel Extreme Tuning Utility as well to set multiplier. On a good X58 board OC'ed it's almost similar performance to the Ryzen 1600. If you're not gaming then the Quadro is fine

There are two versions of the HP Z400 motherboard. The first revision was a much smaller production run, but only had 4 DIMM slots. The 6 DIMM slots is a much more robust and reliable board. Make sure you update the BIOS as the latest HP BIOS for these 7 year old workstations, 3.60 Rev.A was released just Apr 14, 2016. It requires burning a CD to update. The W3680 is the chip you want for LGA 1366, it's multiplier unlocked, cheap, and supported on the second revision board. There's NO overclocking at all to be had in the BIOS, just make sure enhanced turbo boost is enabled, and enhanced memory performance. HOWEVER, software overclocking with the Intel Extreme Tuning Utility(and probably others) allows you to set the multiplier per core usage. i.e., if only 1 core is being used you should be able to get a stable multiplier of 32x with good power supply on the HP board, which is a clock speed of 4.34 GHz I believe. The stock cooler in the HP Z400, supplied by Cooler Master, is quite good if you change the fan, though the proprietary 5 pin connector might require some plastic snipping to get a 4 pin fan hooked up to the top 4 pins. It'll probably then give you a low power cpu cooler error at boot unless you ground the first and last pins together somehow, just press F1. A minor inconvenience for the reduction in noise/ increase in cooling.

The W3680 and W3690 are multiplier unlocked, and better binned chips that were released later than the X56xx series. OC'd these chips are almost on par with the Ryzen 1600. They're ridiculously good performance for the price, even after including the cost of a good X58 board as DDR3 is still a lot less expensive than DDR4, and you may have some laying around already.

pixel response time isn't a measure of total latency either...

I've never tried it for gaming, but it feels accurate enough with fast desktop movements, whatever that means. Build quality is great from Logitech and it feels best with a more fingertip style grip. The Energizer Ultimate Lithiums are 17g each, the Panasonic Eneloop Lite rechargeables are about 10-11g if you can find them in stock anywhere they'd be great.
