We all know, the Raspberry-Pi 3 and 4 heat... not really embarrassing since they can control their frequency to limit overheating to 85°C (it's the famous Throttling).
On the other hand, if we need a respondent, taking advantage of 100% of resources is important... so we must cool the Pi efficiently.
Thankfuly, VentilaPi4 from Garatronic demonstrate that they thinked a little more than our Chinese friends! Long live the French Tech!
This new revision (Jan. 2021) does bring the following improvments.
One GROVE connector is included with the ventila-pi. You are free to solder it as you need it (on the UART or the I2C port). Warning, the connector is sensitive to over-heating (you will have to solder it fast). the Grove connectors are powered with 5V, the signals are 3.3V.
GPIO NOT AVAILABLE as the ventila-Pi is placed onto the GPIO. Using a stacking header allow you to retreives 4mm of the GPIO pin on the other side (but standard height is 6mm height).
Need for GPIO? you can still order the previous VentilaPi4 revision.
Garatronichas also tested the VentilaPi4 with a Pi4 in its case (the case base only). The temperature remains stable at ~52°C despite holding the 4 cores at 100% load for more than 30 minutes!
The VentilaPi4 has of course been tested and offers efficient cooling while remaining remarkably quiet (noise barely noticeable) while ensuring more than 35000 hours of operation (+4 years).
Without active cooling, a Pi4 with open case easily mounts at 50~60°C off load (desktop display, room temp. 23°C).
The use of VentilaPi4 allows to return to 40°C after a few minutes (it is necessary to evacuate the heat accumulated in the board), almost 20°C less... temperature that will be maintained thanks to a sufficient air flow.
The consumption is 60 to 70mA at 5V with a maximum temperature of 40°C off load, 52°C full load (room temperature=23°C).
In stress test with 30 minutes of calculation on prime numbers (4 cores at 100%), the temperature is max 52°C without case (55°C with the official case, without cover).
Here are some suggestions, from MC Hobby, for optimal cooling.
For each order, you receive an assembled VentilaPi4, some screws and spacers are included (use them as needed). No welding operation needed for the ventilator (except for the Grove connector when needed) :-)
Raspberry-Pi not included. Nut-holders (feet to be printed) are not included but available for free download.
The STL file of the nut-holders (recommended use) is available here.
If you are not able to print it, this product is also available for sale here.
