@nightbirdmedia said in Overclocked Raspberry pi 4 without throttling:

I still get the rainbow screen when I boot my pi so it's not getting enough power.

Rainbow on the whole screen on boot? This is normal and is just telling you the GPU has booted up successfully. If you are getting low voltage you would see a lightning bolt symbol in the upper left corner of your screen. If your power strip is good quality I dont suspect youll have any voltage issues.

@Bartrack

This video shows several heat tests on the Raspberry Pi 4 with and without passive and active cooling:

This video is interesting because it shows the FLIRC case (which doesn't come with a fan but the whole case is a heat sink) keeping the Raspberry Pi 4 cool enough and not being throttled:

I have a FLIRC case with the original Raspberry Pi 3B and it works quite well!

@willcroft said in Kodi Builds on the Pi:

Again, is there a build that runs on RetroPie?

Yes - the official Kodi package for Raspbian, as explained in the docs.

@Jekku If you have the nespi case with a fan already installed, you must remove that fan before you can use the dual fan heat sink. Also, use some white scotch tape and tape the heat sink to the raspberry pi with a dry fit. The fan slot in the case can interfere with a proper install. But, there is a certain position while still being able to give full contact to the heat spots on the pi when it is installed. Also, recommend using the flat copper heat sink for the chip on the back of the board. I have actually done this but without the copper heat sink on the back of the board. To be honest those double fan heat sinks actually fall off rather easily if given a light to medium tap. It is better to just use the regular heat sinks with the Nespi case fan installed.

@matchaman I use overlays. Reasonable CRT effect, not as teaching on the CPU.
