@tautech - Both of this famiy were rated at 300W cooling.

@mnem, how can that be a silent copper cooler with a stonking great fan pushing and pulling air between the 2 cores? To my mind silent means running completely fanless as any fan will contribute some level of noise.

That tentacle monster is rather cool, not that I like to bling my PC's up with lights and colour coordination cables etc, to me, they are a workhorse and no more, that said my case has a big window side panel but not from choice, its below desk/bench and so is out of sight anyway.

Any excess cables should be able to be hidden behind the motherboard mounting plate anyway so that they do not impede the cooling airflow in anyway past the cpu and graphics coolers, I'd be perfectly happy to have that PSU in my desktops provided it kicks enough power. My PSU on my daily driver is a Corsair 750W modular unit so if the system requires it, there is something in reserve.

BIGGER IS BETTER for quiet; you should know that. The bigger they are, the slower they can run and still move the required air.

A couple ways they could call it that... first, these coolers were made in the days of screaming 60mm tower CPU fans. While today's standard for a quiet PC is 20-30dB, back then anything less than 40-50 dB was considered good. Secondly, the fan CAN be adjusted so that its maximum speed is very slow and very quiet... easily less than 10dB. A 120mm fan doesn't need to be turning very fast to move a usable amount of air.

Back then, nobody even considered the idea of a truly "Silent" PC... hard drives were noisy, all passive cooling wasn't reasonable and there wasn't a demand. If you wanted quiet, you bought a laptop. The older model Silent Copper with no fan was specifically made to leverage the popular case designs that had a 120mm fan in front/back of the MB cavity and a cold air duct in the side of the case right above the CPU. Technically, it was absolutely silent, even if you put a fan right there.  ;) This one has a big fan with tach, so more modern boards with noise profiles in the BIOS can control the fan for better thermal regulation than passive designs can offer.

And finally... even "Quiet PC" standards are variable today.  A PC can meet "Silent" standards under idle and office tasking and still have the ability to ramp up when under heavy load, like rendering video and gaming. It is expected.

True, I have those fans fitted and I can still hear them but nowhere near as bad as stock fans and they certainly cannot be described as silent unless the person has a hearing problem and cannot hear noises below a certain level?
Are you running them full blast? It depends on the ambient noise the location of the PC and some other factors, but it's definitely possible to have fans that are for all intents and purposes inaudible without having hearing problems.
No, I have 5 x 140mm fans on my PC, 2 at the front, 1 at the rear and 2 at the top on the double radiator all of them are automatically controlled by the PC.

Have you adjusted the cooling profile in the BIOS? Many modern machines have "Silent" and "Quiet" profiles that relies on passive cooling effect and underclocking for idle and low-load work, while still ramping up when demand requires.

My Bios offers me with 3 choices, power saving, normal / quiet, performance and I have left it in the normal / quiet setting which is where it has been since I built the rig 4 years ago. I really like it but just wish that Windoze was a little more tolerant in its backward compatibility with programs written to run on Win 7 and above  :rant:

My Media PC is built with the following:

Case: Rosewill FBM-02 MicroATX Mini Tower
Motherboard: MSI A78M-E35-AMD A78 Chipset FM2 + MicroATX
Processor: AMD A10-7850K APU 3.7GHz Quad Core.
Video card: MSI NVIDIA GeForce GT 610 2GB

It has several fans in it (don't know what kind) but I never hear any of them running. I suspect there's several reasons for this. First, the tower is on the floor and not the bench. Second, I don't game. Third, I don't render video. Just stream video like Netflix or Prime. It also has an extensive music library of wav files and it's connected into my audio system. In all in all it probably just loafs along not generating a lot of heat. So the fans remain on low or probably even off. Maybe I should load it up with something heavy and see what happens.  ;D

Not Displaying any Prejudice today fairly much one of every kind ;D New toy seems happy (untweaked in the photos) from down low to over 1GHz and will eventually get a fixed feed from the GPSDO when they get bundled together.

Edit: Now holding 10000.000 kHz (untweaked by me) and very occasionally flicking a 1 LSD after an hour. Clearly it was  :-/O by it's former owner even with an average internal Osc :-+

That's pretty much the same useage as mine except that I do some gaming but not the latest games but what games I do play are normally in the very highest settings 1080 or higher. I can just about hear my fans but before I went over to water cooling I could hear the cpu fan ramp up at times but these days the noise level always very low,  so low in fact that I can the very faint hum generated by the power supply in my counter keeping it's battery topped up, above the fan noise. No one else in my family it seems can that hum.

Decided to expand the shelving and bench space in the workshop today.

I had to setup a temporary bench to put my repair queue some time ago.



Completely fixed that situation today by adding a metal bench supporting 900Kg and metal shelves supporting 350Kg each.





This is on top of 3 other benchs I have in the workshop. I should have enough space for a while now, or … maybe not  :-DD

Very nice. I spent some time today drafting my new rack too...reorg time all around.

Is that a Keithley 228 on the floor? (brown box's for ALL).

Funny, I did reorganization as well. Mainly to make room for a large and heavy new bit of TEA that's coming tomorrow...  :-+

Hoping to move to a bigger house in a few months so I can have more space to spread out, then fill with test equipment. :-DD

Nope, it's a 619 (Electrometer).

Yeah was also thinking of moving. But the more I organize the space In the workshop, the less I want to leave  :)

Much nicer on the inside than the grubby outside ;) Looks like the cells haven't leaked which is a good thing too  :-+

I reckon I can find a space for it on the rack  ;D

There is a a potentially fairly nasty Mercury button cell in there too somewhere so be a little careful if you find it and it has leaked. My 740B had two I have done some modern trickery to replace with floating references as they are unobtainium these days.

Shipping will be what it is so I won't be put off by it  :palm:

As you all know I just did a major bench expansion last month and already I feel like I'm running out of space. It seems like stuff just appears out of thin air.  ;D And I've got no room for any additional expansion unless I move but that ain't happening.  :scared:

Theres so much room still around that bench, you gotta think modular, compartmental cubbies

Probably put "Out of Service" because the place he got it from didn't have anyone who knew how to use it.  :-DD

I see it too, I got my Fluke 335A pretty cheap and its only issues was a broken dial extension.

First Law of TEA, man...

1. TE will expand to fill all space available. And then some.  ;)

Been looking more than an hour for the baggie full of extensions for my modular power supply. Go ahead Spec, laugh your ass off about mnem vs the Tentacle Monster.  :-DD

Out of service could be anything from no longer in Cal to brain failure  :-// Not to worried it seems to be alive in this case :)

I hope it needs more doing to it than this DUD I purchased to play with YAWN BORING cant even improve it by the correct tongue angle and a swizzle stick :-DD
