Original review from HDPLEX Fanless PC Forum

This is not my system , I just helped one of my friends with the installation.

Specifications:

CPU: Intel i3-4130, 3.4 GHz, TDP 54W, HD 4400
MoBo: Gigabyte H87N-Wifi
RAM: HP 8GB DDR3 1600MHz
Case: Hdplex H1.S + 120W Internal AC-DC + 150W DC-ATX
SSD: Kingston Ssdnow V300 120GB

After the installation we had very bad results with the CPU temp – 78°C immediately after starting Prime95 (Small FFT).
So we had to check again the copper plate.
The problem was that the rack mounted on the copper plate was pushing against the capacitors next to the cpu socket, that’s why the contact between the copper plate and the cpu was not perfect.

So we had to mount the rack but on the other sides of the copper plate, unfortunately the screws were too long. On the other sides – the screw’s hole is shorter because it’s right behind the heatpipe groove. Fortunately we found shorter screws.
@Larry: please provide 4 shorter screws (in case somebody else is using this kind of motherboard).

And the result after the change:

Some pictures with the system:

The CPU temp is 43°C in idle and went up to 87°C after 30 minutes of full load with Prime95. I am not sure about the ambient temp, but I would say it was around 24°C.

Compared to my H3.S system, the temps are higher, but I was already expecting this due to the size of the case. I would say the final result is great and the H1.S definitely looks better.
