“Works as expected, with the same load and same conditions:
RPi 4 with small heatsink: ~61°C average, 74°C peak.
RPi 4 with this heatsink: ~48°C average, 54°C peak.”
“I had the review commnet (that was "This product is so very fine/nice that no extra cooling fan is required." )
Today, this is the additional information for those who are very interested in the overclocking on RPI 4B.
On your responsibility, it is fun to challenge the overclocking with this fine Heatsink.
On my case, after learned from advance user's comment in RPI forum. I did established the new world of my RPI4B-4GB.
I could put the overclocking kicker with following three text lines into /boot/config.txt.
over_voltage=4
arm_freq =2000
gpu_freq=500
With the great cooling performance of this good-design-heatsink, it is never heat over 60℃ even though above overclocking situation.
Enjoy your overlocking - if you want to do !!”
“This metal case is a very effective heatsink, cooling the processor on the Pi 4 significantly. The case provides good protection for the board, but access to the GPIO pins requires the installation of an extender.”
