Net booting in a month or so USB boot after that.
That's in the blog interview video
I can only tell you about the shim - 43deg right now. I haven't seen it going over 50 and I'm using both CPU and GPU (pi4 as desktop) - compiling stuff (100% CPU - even 110%! LOL) and temperature stayed below 50. I suspect if ambient temperature goes over 25-27 deg C it might go over as well.
The fan-shim isn't bad. On one of my pi4's it doesn't make good contact. On the others it does. However, as they aren't secured, I do think they make more noise than they should. I have even tried putting a Blinkt! on top of the header to lock it down. Also keeping the Pi4 in the pibow coupe case with a fan shim does actually increase the temps. Still way better than without, but works better with the top cover off.thatchunkylad198966 wrote: ↑Sat Aug 17, 2019 2:31 pmIs the flirc case that good? I don't want to pay ~£20 for a case and it'll be crap and not work.
I see some people say it's good and others not. can't decide.
Also, how is the fan-shim? that's only ~£12.
My Pi 4 4GB is running constantly so I'd need a fan of some sort to keep it cool. my house is like an oven, though. so the ambient temp is always high. so my Pi 4 temp is always high. 58c atm.
Really? The next reply gives you the answer.

Another great product from the Raspberry Pi team. Can't wait to get my hands on one (when the 4GB ones are back in stock).
Yes it bothers me. I have two words to describe the Raspberry Pi 4BSynGreis wrote: ↑Fri Sep 06, 2019 12:54 pmdoes that not bother you? Opening a browser to view your camera and it goes up to 80 celcius?
No thanks my pi2+ can do it better and it remains at a great 40 celcius where it should be.
Im seriously considering returning it. Ihave used it for maybe 2 hours to run tests and i found out it gets way too hot.
Not true. I don't have any heat reducing measures on my Pi and it works fine, although I don't have it in a case.SynGreis wrote: ↑Fri Sep 06, 2019 1:01 pmi get that there is accessories for the pi to increase performance but the fact that you essentially you need it just to use your pi on a lightly used basis is a deal breaker for me.
This is not a good buy. Ill extend the benefit of the doubt that i just might have received a bad pi given my overwhelming positive experience with the pi 2b+ but this pi 4? No. I cant use it properly without it overheating badly.
Warranty is from where you bought it. We've sold a LOT of Pi4's already, with very few problems, so the next one will almost certainly give a much better result.
A heatsink with no addtional air flow can make things worse, especially if the sticky pad doesn't have good thermal properties. The whole board is designed to be a heat sink, so even a small airflow over the whole board makes a big difference.alphanumeric wrote: ↑Fri Sep 06, 2019 12:44 pmMine hits 80c with just a browser window open showing one of my camera feeds.

If I turn the floor fan on in that room to circulate the air a bit it goes back down to ~60c.
The heat sink is 40x30x5mm, its the one made for the Pibow Coupe Case.

You can improve the coupe case by removing the 2nd layer down to allow more airflow over the whole board,

There been quite a bit of input from Pi engineers on this and other threads with regard to cooling.alphanumeric wrote: ↑Fri Sep 06, 2019 3:04 pmThe heat sink is 40x30x5mm, its the one made for the Pibow Coupe Case.

IMHO some official guidance from The Pi foundation on what to do and what not to do is in order. If its out there I haven't found it? Especially concerning the Official Pi 4 case.
I'm a retired Electronic Technician, I get that some electronics need additional cooling. It's just that it seems to me, we have been left on our own to figure out what works and what doesn't. Having your electronics overheat to figure out you got it wrong isn't the way to go, IMHO. I'm a bit frustrated as I bet a lot of other Pi 4 owners are. You have a big potential for performance that you can't maximize as it comes out of the box. Unless you go with no case I guess?
