I've seen my water cooler doing a good job. When I render for 20 minutes or more with CPU on 100% all cores it keeps it really cool. I don't believe my old air cooler could have done that but I can't prove it.

  So Freddy is using a Zalman cooler and I have chosen Intel, I've got good and bad reviews about both coolers, worst is both have the cooler stopped after 2 years time.  Seems it would be nice to have a reserve tank  like we do in a car and some thing to indicate the water level. It should be easy enough to do that.  I wouldn't mind if they gave you a cooper block that you could put an air cooler on the other side.

To be honest I wouldn't expect much more than a couple of years life for those. I suppose the best thing to do is keep an eye on temps - then when in the future it doesn't seem to be working replace it. Two years is roughly my cycle on major upgrades anyway.

The thing that concerns me is leakage... but in for a penny in for a pound.

  Quite a few years ago I had a marine aquarium tank, and naturally it needed a pump to circulate the water, I'd say the pump lasted at least 5 years without a problem, not sure what happened to it but never a problem or leak.  The aquarium pump is 24/7 where as the water cooler is about 5 hrs / day for me.  Those prices I'd expect min of 5 hopefully 10 yrs.  I'd make on with a cooper block, cooper pipe, and water circulator outside the case before I'd put up with that bs.  Anyways I suspect some type of abuse or misuse is the cause of a majority of the problems.  You probably didn't notice but the "STW 5.25" 6 in 1 USB card reader  $38 also has a probe to monitor temps, I think the Bios also has a temp setting for the CPU and will shut down if exceeded.

The link is for monitoring 2 temps $47  the one I mentioned above is for 1 probe $37

What I've played with uses a 5.25 bay water reservoir similar to this one but 1 bay not 2.

That way you can see the water and the flow. And if you want fancy, you can get UV pipes and put a UV LEDs in it.

  Thanks for trying to help I think I let myself get upset with this liquid cooling.  Worst part is I remember making a cold plate ages ago out of a copper or brass block, drilled a series of holes and plugged and soldered all but the inlet and outlet for water flow. I did run across some brushless motors used for the circulation pump which I'd put outside of the case which only leaves a cold plate inside the case
  I keep seeing reviews for the liquid coolers saying they are failing.

Nevermind, I often get upset 

You may well be right about the drawbacks Carl, I just thought I'd give it a try and see, hopefully I won't regret it.

Speaking as one who uses liquid cooling, I'd prefer to opt for a solution that comes pre-plumbed and sealed at the factory. This doesn't prevent leaks, mind you, but it does reduce the risk considerably.

This is what I'm using:

  I believe you are in the majority,  liquid cooling is new to me and possibly it has progressed in ways I'm not used to.  To me a solid copper cold plate with an inlet and outlet for water ( a nonconductive fluid would be better ) , move the pump towards the radiator and place them outside the case. 
  I've actually started looking at the air cooling and just started finding some made for the motherboard, next is to check the sizes available in the case.

I've found a lot of good videos on youtube,  a good one that I like is the 5820 vs the 4670K, the link :
  seems the 5820 is a power hog, it also has a slower boot time.
Also got and ad from HP, they are selling a 5820 compute for about 1100.

Carl2 I've moved your post to this thread.

Yes me and Freddy have seen that video and debated the results.

The guy is mostly talking about gaming performance and the i5 ( 4670K ) is really the CPU of choice, without doubt better value for money for games. But games don't really use any more than 4 cores yet.

It comes down to what you want to do with the CPU, Freddy does renders with it and uses all the 6 cores so for him it faster than an i5.

Of course 5820k will take more power because it has 2 more cores and more cache too.

Don't forget the 5820k runs on the X99 chipset which has quad channel DDR4 memory, quad channel RAM is faster than dual channel but the software you run must be able to take advantage of quad channel memory. Games probably don't take much advantage of it.

The fastest booting computers I have seen were i3's on micro ATX motherboards with nice SSD's. Faster than i5's and i7s. With an i3 on a micro ATX board there is less hardware to detect and then install drivers for on boot.  

Remember the first post I made on the M.2 thread I started, it used an i3, I posted that for a reason

It's horses for courses, what are you going to do with your PC.

Data,
  Frist I'd rather think we are discussing a topic and not having a debate. My main reason for pulling in the video was with respect to cooling the cpu since that is what I'm concerned about at this time.  I'm also concerned about boot time and would like to try out the M.2 and wished he had talked in more detail about how the drive was hooked up.
  I'm pretty sure this computer spends most of it's time idling and unless something unusual comes up the following computers will probably be pretty much the same.   
Carl2

My apologies Carl2, I will try not to use the word debate in the future when communicating with you.

I see no reason why we can't discuss the cooling requirements of an M.2 PC build in this thread though.

Sometimes people can make the mistake of thinking a faster CPU will make a quicker booting PC, these days it is not the case, boot time is more down to the amount of hardware in the PC, graphics cards, drives, soundcards etc.

The fastest booting systems are those with on board graphics, on board sound cards and less drives. Which is why an i3 with all onboard hardware can boot so fast with an SSD.

The chap in that video doesn't seem to grasp that, nor does he really consider that faster clock speed of the i5 running at 4.6Ghz vs the i7 at 4.2Ghz or consider the X99 form factor is not the same as the i5 iether but I was building computers when he was about 8 years old.

Data,
  I don't want to make a big deal over your choice of words, but I did see something about saving energy  between you and Freddy I think I decided I don't want to get involved.  I actually moved to liquid cooling because it was no longer about the M.2 but I do jump all over the place depending on what I'm thinking about at the time.   I've had my share of talking to people who should be able to supply a solution but were unable to. 
   I just received a promo code 15 % that can be applied to the discounted price of 1,199 for the HP 5820.  Sounds good but after looking at the the motherboard in the last HP it looks like they did a lot of skimping 1 full Pic ex for a video card and 3 very small x1 slots. 2 slots for memory.

Yes indeed we have to be careful with the motherboards on these pre built PC's. I have found some of them don't have a make or model number, we don't know who made them or where to get BIOS up-dates or support if needed.
