Mach II XXHighEnd PC with Linear Power Supply

[Arjan]

Looks really nice.
In my situation it will be NOS1a next to B'ass next to MachII.

All,

We must be careful a bit, because this text I removed right before posting the tex about the V4 case :

This can be had for 525 euros (ex VAT) and this price anticipates single unit production.
Careful, because like with the B'ASS case, the finish is not clear yet.

I thought to better sort out that finishing method first, hoping that today I would be further with that.
But I think I can see that because I left out that text, you could think that the price is the same as with the other case. Well, if that could be true ...

So this 525 looks to be on the safe side for us, but if whatever finish costs 50 more, then it will be 575 ...

But uhm....

How does the NOS1a fit on top of this? Maybe this on top of the NOS1a then.

 

Hi Gerard - A two-folded answer :

First off, I reckoned that footers of the device on top of it have a certain thickness. This thought emerged with the idea around the cooler. This in the sense of "can be OK".

Next up was the determination of the "sticking out" height, and this appeared to be 9.5mm (0.368"). This is now a given fact.

The footers we plan ourselves are 8mm (0.32") of height. So those would be too "low" (short), when a device with them is to be placed "over" the cooler (on top of the PC).

While the thought of "could be possible" was only just that, I next reckoned that people should not stack devices like that in the first place and they merely should have separate shelves.
This is where my tinkering about this stopped and continued the design ...

I forgot to tell the height of the V4 Case.

Including footers this is 84.5mm (3.38"). Without footers it is 76.5mm (3.06").

Including the cooler and footers the height is 92.5mm (3.7").

Peter

Ok clear 

Not too big of a problem.

Peter - to be honest as sound quality is my top priority I am not sure I would want to pay 525/575 for the case will it still be an option to have the silverstone case?

Cheers

Paul, Yes !!

Some want it "chique" and this one is meant for them.

... Such a nice cabinet... And I love the cooling touch that you designed !

Hi Peter,

still an unanswered question.

Price for the LPS to be implemented in the Phasure PC MK I?

Thanx
Joachim

Hi Joachim,

I have very explicitly told that this LPS will not be sold separately. IIRC you asked the question an hour after I told so and why.

Sorry !

Best regards,

I am quite sure that fanless will not work in my (Australian) environment even when the cpu is throttled down.  

It is winter here...30 degrees celsius today...what a beautiful day!

Haha, well you were quite wrong.
So you have it 30C inside eh ? LOL
Anyway, let's see :

For the 2640 (and further controlled environment) : With 24C ambient the cpu will get to 59C. This means that with 30C ambient the CPU will be 65C (yep, it just works like that), with the notice it is allowed to be 76C (continuously).
It is only that the 65C won't happen because the (now present) Thermal Protection will kick in at 60C and start the fan (just very low rev) and in 90-100 seconds it will be at ~44C (which is where the fan stops).

So in the end you would be right. It is only that I don't believe that you have it 30C in there (but hearing about having it 10C at winters inside (is that really common ?) and I should put no money on that).

Something else is that for the 2650 (and 2660 I suppose) this won't work (it works but each 9 minutes the fan kicks in for 90 secs). So I adjusted the first post with that observation; The 2650 and beyond must work with cpu fan (inaudible), which we do not with PWM control (better for electrical noise).

Hi Peter,

sorry, never saw this info, but now I know. Thanx.

It was about 10 degrees this morning at sunup and reached 30 before lunch...perfect day apart from a bit of wind.  Not a hot 30 degrees though because no humidity, just a beautiful comfortable day.  Mind you four days ago we had strong south-westerlies blowing cold air up from the Southern Ocean over the continent and it got to 10 degrees maximum with rain...that was a shock to the system!

Anyway, yes, I would have 30 degrees or more inside the music room very, very often from say September to May perhaps.  A wall of windows to the north with lots of natural light but little airflow, unlike the rest of the house which has wonderful airflow from every direction but the south (cold when it blows from that way).  I have had passively cooled audio computers before (i5) and they just do not work when the humidity gets up (the case goes from luke warm on a dry day to toasty on a humid day) so I am very wary of them, but perhaps they were not as underclocked as the Mach II.

The thermistor and fan is a good idea though.

So 30 degrees in the music room today? It would have been pretty close (I did not go up there) but it certainly would have been at least that had those 24 valves been glowing today.

Hey Joachim,

I can understand that you possibly got agitated by me not answering to your question on May 20 (http://www.phasure.com/index.php?topic=3621.msg38760#msg38760). But what should I do if in the post you respond to (which was from 30 minutes earlier - http://www.phasure.com/index.php?topic=3621.msg38758#msg38758) I (thus very explicitly) say this :

It is thus not so that, for example, the PC can be bought without its dedicated power supply, that it can be shipped with 16TB of harddisk inside (which btw sure would fit), that it can be shipped with a random untested processor, or that the Linear Power Supply can be provided as a separate unit;
Instead, it is a dedicated machine purely made for the best audio possible as how Phasure could create it.

Outside of this, I feel that you sure will have read that, because of your response directly to that :

I think/hope the LPS should work with the older X79 mobo too. The max TDP of the Xeon 2640v4  is 90 W, and that is a higher rate than the 80W of the Xeon E5-2620v2.

So I say it can't work and that the LPS will not be sold separately and 30 minutes later this is the question. Who do you think is agitated here ?
Allow me to add, because otherwise things still may be in doubt :

You bought the old PC, thought that it could be powered with an LPS, started tweaking with that yourself (you never asked me in advance (not that you had to, but I did not know anyway)), asked me questions per email and I tried to help you, to end the communication about this with you saying that you did not tell me all there was to tell (sort of) and now it did not work. This was on May 15, the same day this topic started ...

Let me be totally clear :
When I would have thought even the slightest that the old PC could have worked with this, I would be still selling those. Because remember, I still have a few (see topic about it). So instead I throw these away ? ... apparently yes.

In the end the message in that "Controlled Environment" paragraph in the post I linked to, tells that what I did here is so special that it can only operate without catching fire and other misery, when it is in a controlled environment. This is literal. And this environment now is my own.
Maybe I should refer to your own experiment again and that it failed. Why ? not because you don't know what you are doing. But say that I prepared for this several years (throughput) and that at some stage I started to see the light. And this worked out on April 30 2016 (http://www.phasure.com/index.php?topic=2726.msg38539#msg38539). All I needed really was a change of mind set, and work on the idea that the old PC now indeed was old enough to be called obsolete. So it went on sale on April 3 (http://www.phasure.com/index.php?topic=3594.0). This was really the day that I finally could start thinking about something else.
So I did !

Best regards,
Peter
