2 case fans (*i.e. one in the front, set for intake, and one @ the top set for exhaust).  The Dell webpage list there being 3 case fans, 2 intake, and 1 exhaust.  I believe they are counting the PSU fan as a case fan, unless I'm unaware of another fan.  Adequate - pretty good is how I would describe it.  I recently purchased a Samsung 960 Evo, and GTX 1080ti (awaiting release of EVGA Hybrid kit), and both those components are well known for generating A LOT of heat.  Therefore, on the CPU I'm staying air cooled, although have no need for cpu liquid cooling being an i7 6700, nonK.  My hopes are that the extra air from the CPU fan in the system might assist (pipe dream) in cooling the memory, and m.2.  The non-K cpu's are not liquid cooled, and the K-unlocked cpu's are.

Case fans are relatively inexpensive however, and yesterday I purchased 2 Arctic case fans w/ 74CFM rating.  I also purchased an Arctic CPU cooler, as it was inexpensive, and likely more efficient than the stock CPU fan.  The stock fans, as w/ most components INSIDE Alienware machines, are unfortunately value brand (*i.e. trash). 

I haven't changed the speeds of the case fans since purchase, and Ambient temps stay cool.  However, since adding the 960 Evo, and the 1080ti, Ambient temps have been seen @ 60.  Hoping the better case fans, and the eventual addition of the EVGA Hybrid kit improves said temps. 

Bottom line, if you want quality, or become fixated, you'll likely change a few things out.  That said, I don't regret purchase, but won't be purchasing Alienware again.  I'll be building my own.  The case, and it's no tools entry is masterclass.  Everything else... use Alienware worthy components for God's sake DELL, and bring some dignity back to the name!

Your reply really helps but although owning and using computers for over 35 years , and three Dells, I am not hardware icompetent. The Aurora main page mentions "engineered with liquid cooling" but for at least the basic $800 model that is appears untrue unless you upgrade the basic 460w PS one step to a 460w PS with hight performance Liquid Cooling  so if that is the liquid cooling referenced an "engineered" just where is that applied?

What I want is a fast computer (probably be my last at 84 years) with some entry level gaming capability (I doubt if I will ever be a big gamer).  I will accept the basic Radeon RX460.  However I will upgrade to a 256GB SSD (which I want for the programming loading speed) which comes along with a 1TB HD - more than I need but will find use at least for images (I am a backup freak).  So sounds as if I will get the two fans plus a PS fan and how does that sound you you to adequate cooling for processor, memory and SSD?

Appreciate, Ed

Never mind that first one was better as the 2nd one is HDMI only, and is therefore only capable of 60hz refresh rate.  The 1st one has a displayport input.  https://www.bhphotovideo.com/c/product/1224159-REG/lg_34um68_p_34_21_9_ultra_wide.html

Sorry cut myself off.  The liquid cooling will be on the CPU.  I think that sounds pretty good brother.  The last thing I'll mention (*Not trying to get you to buy stuff lol) is the PSU.  It's loud, and low quality.  I found an EVGA 600W Bronze 80+ PSU for $35 on sale @ BestBuy.  It's not necessary to immediately change out, nor are the fans, however considering cooling is one of your priorities I believe both better case fans, and a better PSU (*Which also has a fan) will result in much better temperatures, and less noise.

No doubt I wasn't suggesting you were. 

Do you mean the RX480?  Good card.  Are you familiar w/ Free-sync?  It's AMD's adaptive sync technology which syncs the refresh rate of the monitor w/ the number of frames the gpu is outputting @ any given moment thereby eliminating screen tearing, and stuttering.  (*eliminating in theory)  It's incredible.  If shopping for a display as well I HIGHLY recommend find one w/ Free-sync technology.  Here is a suggestion:  https://www.bhphotovideo.com/c/product/1224159-REG/lg_34um68_p_34_21_9_ultra_wide.html

Here is a better deal on essentially the same ; https://www.bhphotovideo.com/c/product/1279021-REG/lg_34um59_p_34_21_9_curved.html/prm/alsVwDtl                                                                                                                                                

I guess VR has a bit to do with it. But, do you want to Windows Game on it ? (and I don't mean Solitaire)  

If you are going to get an Intel-i5 processor model and a small video card ... I guess fan cooling and the small 460w PowerSupply is ok (if you must) .  

For any Intel-i7 (and/or nice video card), I suggest the Liquid Cooler and 850w Power Supply. Quite a good deal for $100. Give yourself some room to grow.

Added Edit:

I've always said an i7 CPU (or nVidia 1060 and up) on an Aurora R5/R6 without LiquidCooler/850w-PS selected should throw a sales-page config-error ... but everyone wants cheap. Well, you get what you pay for and how many users trying to save a few dollars are now looking for cooling and power-supply upgrades? Just sayin ... search this forum for yourself.

Yes, LG is good.

I guess 1080p still works fine on these double-wides (because they are not that "tall").

But with all the available monitors, sizes and technology ... for Gaming and other high-end uses ... we really should start a new thread.

I suggest this. This is pretty-much what I bought/have but with a few down-grades to save you some bucks:

Alienware Aurora (R6)
Intel i7-7700 - Intel z270 Chipset
16gb DDR4 
850w Power Supply & Liquid Cooling
Nvidia GTX-1060 OEM
SSD 512gb (M.2 PCIe NVMe)

Toshiba 1tb 7200rpm HDD (if you have a lot of music, video files, etc)

DVD Burner (or Blu-Ray if you want to play those discs)

Killer Networks e2400 Gigabit Ethernet RJ-45
Intel 3165 802.11ac Wi-Fi & Bluetooth v4.2 (it's included ... DO NOT get Killer-WiFi)
Alienware Keyboard and Mouse (free)

Windows-10 Pro (64-bit)

Dell 27" u2717D UltraSharp Infinity-Edge IPS 16:9 QHD Monitor (pretty awesome for gaming and everything else)

Dell AE415 2.1 Speakers (no speakers on u2717D)

External USB-3.0 Hard Disk Drive (for Backup Images)

APC Back-UPS 1000-LCD

Edit: Sign-up for Dell Advantage Rewards first.

You will get free/faster shipping, maybe an extra discount, and after about 45 days ... use your Rewards to buy the Speakers, USB-HDD, or APC-1000-LCD, etc.

You guys are awesome.  Mind you I did mean I am hardware incompetent, so much so that I did not even spit it out clearly.  My computers are a major hobby.  Have programmed in most every language over the years (again not my trade but just enjoyed) and am not a bad repair man for all my neighbors in this "old age home" (of course they call is independent living and my wife of 60 years and I have a nice large appartment).  Just finished a course (vitual) from HACC (Harrisburg, PA on Microsoft SQL Server. I did enjoy a few years back playing Sniper Ghost Warrior and Minecraft (built elaborate worlds but could never handle the monsters or what ever they were called - had to play in safe mode or just kept dying - and that was with a Dell546 after adding a Galaxy GeForce GT 440 512MB DDR5 PCle     display card near the end of the computers life.  It died last year and I am stuck with a Dell 660S.  Now you know were I am coming from.

So again what I am looking for is a very fast computer (I am very impatient) and started looking at the XPS but you cannot even get an SSD as an option, in fact options are few.  So that is why I turned to the Aurora.

and Drewsky's comment about noise discourages because I like quite machinery. Are any of the upgrade options listed  better than the base 460w or do I have to replace as he did?

Tesla1856 makes a point the entry level $699.99 is  below the water line and maybe sinking.  At 84 I really hate spending more than $!000 although I do remember spending over $3000 for my first IBM PC in 1982, and then the next one two and maybe the third - way back when.  You guys would have loved what was the beginning of forums - BBS's and the snail pace of transmission - I did have patience then.  Which raises one more question and that is what are the letters such as Aurora R2? - I do not see those on the Dell site.  Just upgraded components on the same motherboard and case.

Appreciate,

Ed
