First time experience building a water cooled PC.
Long story short I acquired a i9-14900 to replace an i7-8700 for Raspberry Pi work and discovered it runs hot, like really really HOT. I had no idea a CPU could put out so much heat when not overclocked!
The system runs Gentoo Linux (a build from source flavor of Linux) and naturally more CPU cores/power will help with quicker compile times.
I had no idea how hot this i9-14900 was going to run and started out with a simple air cooler and boy was I in for a surprise, instantly pegging 100C.
Not only the simple air cooled heatsink was to blame, but the default motherboard settings (which we all know by now really push the CPU into unregulated overdrive it not changed).
I never thought I would see the day I would build a water cooled PC, but that day has come, with no first hand experience, and the only information from which I have watched on TH-cam (and there is a lot of videos out there) it was time to take the plunge...
I had no idea how far this rabbit hole would go, and I am still not out, but I can almost see the light after some initial experience.
The purpose of this build is for compiling code and working on Raspberry Pi projects so there is no discrete external graphics card used, will be using the internal CPU graphics.
Also the NVMe 256GB storage below is just for the root filesystem, data files and project files are on a 4TB SATA spinning hard disk. Speed is not important so just went with the best bang for the buck deal.
Distilled water is not easy to get so I did not have any for this project early on hence the use of tap water. Not to worry, I ordered 20L off Amazon and it has arrived. In the next session everything will be flushed with distilled water.
The video turned out to be quite long so I have split the first video into 4 parts as a result. I will be uploading more content as I work on this rabbit hole project more.
