Silent PC build with HDPLEX 2nd Gen H5 and Intel Core I9

Hi,
I want to show you my silent PC build with the following components:
  • HDPLEX 2nd Gen H5 fanless case with the 400W AC-DC+400W HiFi DC-ATX Combo power supply
  • HDPLEX Passive Video Card Heatsink System
  • HDPLEX Silicon PCIEx16 3.0 Riser
  • Gigabyte Z390 DESIGNARE motherboard
  • Intel Core I9-9900 processor 3.1 GHz
  • G.Skill Ripjaws V - 32 GB DDR4 3600 MHz (2 modules of 16 GB)
  • 2 x Samsung 970 Evo Plus 1000 GB (M2 SSD storage)
  • Asus Nvidia GeForce - ROG-STRIX-GTX1650-4G-GAMING video card
  • ASUS TUF Gaming VG289Q 4K monitor
First of all, the HDPLEX H5 is a very well manufactured product. It comes in thorough packaging and you get a comprehensive installation guide.
The build does take time, but it is not difficult.
And Larry from HDPLEX is very helpfull and quick with email response if you have any questions.

Both sides of the case are a big and heavy heatsink and they each have a maximum Thermal Design Point (TDP) of 95W, but around 65-75W is recommended. Therefore I chose the I9-9900 with a TDP of 65W, which is not the fastest I9 processor. And I also chose a mid-range NVidia Geforce card with a TDP of 75W.
Still I think I have a fully silent system that has above average performance.
I will use it for software development, deep learning algorithms, music production, video editing and some moderate gaming.

The motherboard is very nice, with a huge amount of connectors.
The M2 connector for the SSD storage is super easy. They do not take any space in the case and do not need any extra power connections.

At first, I did buy a graphics card that did not fit with the heatsink copper base. This plate supports 48mm, 51mm, 53.3mm, 58.4mm or 61mm mounting patterns (distance between the screws). The card I got had a distance of 43mm between the screws.
So a bit more research is needed to find a card that does fit. Before buying another card, I searched for a picture of the backside of the card, where the screws of the heatsink are visible. In this picture I measured the number of pixels for the width of the PCI-E connector on the card, which is about 70mm. Then I measured the pixels for the distance between the screws and could calculate that it was about 51mm. And indeed, when the card arrived, the heatsink did fit nicely.

First, the powersupply, motherboard, memory, CPU and CPU heatsink copper base are mounted.
The 2 SSD drives are already mounted under the heatsinks between the PCI-E slots.

Then the heatpipes for the CPU are installed.

Then the copper base plate is mounted on the graphics card.

And the graphics card is mounted in the case, using the flexible PCI-E riser.

Then the heatpipes for the graphics card are installed.

And all is complete.

I am very happy with my new fully silent PC. Much better and hugely faster than the noisy I7 laptop I was using.

One more tip for using a 4K display: Aquasnap software is great for managing windows.

(all in celcius)
CPU cores average around 45, often goes to 53-55 and sometimes a peak to 63.
Motherboard on various locations between 33 and 53.
GPU core around 38-40.

Pretty impressive, now you are making want to build like you.

How are the temperatures under full load for an hour?

Seems like a pretty good build but I have a couple of questions
1. This computer is for work or for gaming
2. Does it overheats when you are trying to play something in 4k resolution
3. Ho much does it cost you
4. Did you order parts from Amazon or somewhere else
5. The only noise in the system comes from the graphics card fan?
