Re: Streacom DB4-based Completely Silent Computer

Yeah, you are seeing the capability of the CPU cooler header to quickly transfer heat up to a point and then the slower tail of the heat pipes transferring heat to the case. Pretty typical of passive designs.. Ah... All of my previous machines have been air- or water-cooled and their curves did not...

Re: Streacom DB4-based Completely Silent Computer

I'm always interested in the soak time curves as it provides a good feel for how well the platform can cool and where some of the limitations may be. It looks like the limit of transfer with 6 heatpipes is 42C to the exterior of the case (same temp for 75% and 100% loading). I'm not sure that sayin...

I've completed the first round of CPU thermal testing — a full write-up can be found here.

The final results (normalised to an ambient temperature of 20⁰C) are:

Re: Streacom DB4-based Completely Silent Computer

Thanks Steve. Haven't gotten around to any rigorous thermal testing yet. Waiting for Ubuntu 18.04 LTS to drop (in four days) before I do a clean install and migrate everything I need over from the old machine. Light use and an IR thermometer suggests good conduction to all of the spreaders and no ob...

Re: Tips for selecting RAM in 2018

All things considered, a good guide. I do have a few points to make, though: If you have a motherboard with two slots, it's better to go with one larger capacity stick than two smaller ones since you can always upgrade the second slot later. If money is tight and performance is less important, then ...

Re: Why are there no good HDD silencer in 2018?

An alternative to storage drives of any form is now the Cloud. For example a Evil Empire subscription will bring with it 1TB of Cloud storage. Yes, there are issues about Cloud storage particularly the need for a reliable, reasonably quick internet connection. But it does make the SSD boot drive + ...

Re: Why are there no good HDD silencer in 2018?

I'm surprised HDDs are still being manufactured, to be honest. Cost is still a significant factor. From my local supplier the cheapest 1TB hard drive is around 25% of their price for the Samsung 860 Evo 1TB equivalent. Interesting that you compared the cheapest possible HDD to the second-most expen...

Re: Why are there no good HDD silencer in 2018?

Silent PCs and SSDs are common in 2018, but HDDs are still around for large storage. I don't think that a lot of people will buys 2tb SSDs for storage soon. I built a new system a couple of weeks ago. Put in a 1TB Samsung 960 EVO NVMe M.2 SSD as the system drive and a 1TB Samsung 860 EVO SATA SSD a...

Re: Sound Level Meter suggestions please

Before throwing ur monies away, why not check out those smartphone apps, often free, may be just do the job. That's what I have been using. Unfortunately, smartphones use a microphone technology that can't detect sound pressure levels below ~30dB. The software is irrelevant — it's the hardware that...

Re: Sound Level Meter suggestions please

The jump from 30dB(A) to 20dB(A) involves a couple of grand or more... Yikes! :shock: Sounds like 30dB is the threshold for a particular type of 'mainstream' microphone technology... and sub-30dB requires something quite different and more specialised (thus more expensive). and realize any app usin...

Re: Sound Level Meter suggestions please

I'm in the same boat. Looking for a meter to get some objective measurements.

All of the meters in the above list are 30dB+ but my environment is already down to 35dB (at least, according to the app on my phone), so I'm after something that is sensitive down into the 20s.

Any suggestions?

Re: Interested in a Ryzen - Fanless System

I suppose water cooling with an external convector is the way to go for proper cooling. Might allow for some more powerful GPU as well... Sure, but water cooling means pumps and pumps mean noise. If they're happy to settle for quiet instead of silent , that's an option. I actually really like the l...

Around 8 years ago and due to SPCR I bought an Antec 182 case ...
