Thanks for your report! Unfortunately, I found out that there is practically only one source for this heat sink and that the penalty fee for the cheap cooler doubles the price. A quick search led me to a blogger who has mounted a Northbridge cooler that can be ordered at a lower price. The link in the blog no longer works, but this Northbridge cooler was quickly found on AliExpress and ordered even faster. As soon as I have the cooler and VisionFive 2, I will put a Noctua NF-A4x20 5V PWM fan on it.
Addendum on 13.3.2023
As I found out in the meantime, there is a Polish online shop that sells both the Odroid cooler with fan and the passive Odroid cooler at favourable conditions throughout Europe.
