There has been some discussion on this in other topics, even going a bit further, whether V4 or the ‘zynductor’ would be enough cooling to allow 2GHz overclocking.

To ‘cut to the chase’ from @ [jofemodo](https://discourse.zynthian.org/u/jofemodo):

> If you have V4, you could use overclocking carefully, given that the zynductor is well installed. If ambient temperature is low-enough you shouldn’t have problems when using maximum speed (2GHz), but be warned that you probably would have problems if ambient temperature goes beyond 20ºC.

> If you keep an eye on system temperature by refreshing webconf’s dashboard, you could change to a lower overclocking profile when temperature goes higher than 60-65ºC.

So… if you added more cooling, like a fan, you could survive at even higher ambient temp.

For the fuller discussion see:

> Hi Zynthianers, Is anyone running - with stable hardware behaviour - a 2020 official V4 kit at full 2 GHz overclock? I am wondering if the Zynductor heat bridge would manage to keep the 4 CPUs at safe temperatures, without damaging the cores or sending them in heat protection lock, each time a substantial audio processing occurs. In order to possibly attempt the overclocking, I am switching from the mainstream Raspi 4 PSU (5.1 v, 3A) to a more robust 4A. What I obviously aim to is squeezing …

and for even more, search on “zynductor”
