You could use thermal epoxy, or some of the larger heat sinks are bolt-on so you can use paste. If you use tape, make sure its proper 3M tape.Weiand wrote: ↑Fri Mar 20, 2020 8:25 pmHeat sinks... I see a few different brands / types out there. The ones I've seen claim to have a thermal tape, which reviews seem to say it isn't thermal and to remove that and use paste. Doesn't seem like it would stay in place though or stay in place tight enough.
If you want to play mp3 files, you don't want a noisy fan in background.
There are no issues with 64GB SD cards. NOOBs may need to be formatted with FAT32 instead of exFAT. Normal OS installs need nothing special and work fine. (I have used 128GB cards with no problems).
A 3B+ is going to be perfectly fine for most applications, but if you want a RPi for a desktop computer - get a Pi 4. Its responsiveness is at least 4x as fast.
<off-topic> You would not believe how many noobs think they need a graphics card for their Pi. FYI it's built-in. </off-topic>
Raspberry Pies have always been designed to be in an enclosed space with no active or passive cooling.
Usually not, unless you're compiling something (continued high CPU usage), or overclocking (literally running the CPU on a higher voltage to run faster).
Not sure where you read that. On the contrary, my Pi3 was had no problems with a 64 GB SanDisk Extreme Pro. (High-end SD card)
Windows can only see the boot partition of the sd card. Raspbian Buster OS has a 256 MB boot partition and the rest can't be seen by a Windows PC. If you just want to play MP3s, I can't imagine why that wouldn't easily fit on a SD card. After all, a single CD (0.8 GB) can hold around 8 hours of MP3 songs. So I can't imagine you needing a 4TB (4000 GB) hard drive to store the MP3s.
Yea... that seems to happen a lot. I just like to be a bit prepared, not just run in blind and "let all the smoke out" of things too fast.You have a lot of questions and I suspect you might be "other-thinking" it.
Here is a Pi4 4GB outside of a case - no fan.

Bear in mind that Pi4B SoC is dissipating--at most--6 to 8W. The whole board, at max load, is only handling 15W. Of that, 6W is available to USB devices and various smaller amounts go to HDMI, Ethernet and GPIO pins. It's likely the cooling system for your i7 CPU takes more power than a Pi.
My first reaction: What a waste of power!
First, bear in mind that it is typical to over-spec PSUs (aka run them at a relatively low load factor), so that PC is probably using a lot less than 1200W. Most of the time, it might well be less than half of that.Botspot wrote: ↑Fri Mar 20, 2020 11:11 pmMy first reaction: What a waste of power!
My second reaction: I wonder how many RPis could have been purchased with the money spent on that i7 PC...
My third reaction: Selling that thing and spending it all on Pi4s would probably get you many times the processing power as that i7.
