Pi 3 B+ Question
-
Mileage will vary, but i was able to get 1533mhz arm_freq and 600mhz core_freq which i focused on for N64 emulation using the 3B+. One hair over 600 on the core and it would fail to boot or present graphical madness...
Using a single fan in the new nespi+ case with a fairly large heatsink from an old Netgear VPN/firewall the max temperature i saw under load after running 24 hours was 56 degrees. This is inside an
open back cabinet on top of my xbox one x which i was running at the time too so had it been alone in the complete open it likely would not have hit 56 at all using just this..I think the dually fan is overkill and may consume more power then its worth, but i guess it all depends on what youre doing.

@ecks "Whilst hitting the temperature limit is not harmful to the SoC, it will cause CPU throttling."
This is straight from the raspberrypi.org website. As long as you aren't throttling the temp doesn't really matter.
I realize that the super kintaro heatsink won't fit the 3 b+, I was just using that as an example, that even under the most extreme load I was not getting throttling even without a fan. As a side note they are working making the next gen of that heatsink compatible with the 3b+.

I will let you know as well that my Pi is also inside my arcade stick which has very little ventilation which is good to have something cooling it down and another thing is its the warranty for the Pi which states if the system stays over 80 degrees that the warranty will expire and honestly you can not say they won't know if you send it back asking for it to be fixed or replaced because they have ways of knowing.
The one thing most people like yourself always tends to forget is people does projects such as bartop arcades and arcade stick in one systems (like what i did) which tends to not have a lot of ventilation inside of it which you might see some projects using 120mm fans in the back of the case or using a small fan like the one i have in mine. -
Just a note of interest for anyone who may stumble across this thread, old skool tools has released an updated design for their SK 9000 heatsink that will fit on the new pi 3b+!

Are you sure you have the right name cause i googled it and it showed me other things than a heatsink for the Pi 3B+

Click on the "size" options and you can select pi3b+

@ecks i think this dual fan cooler is useless, i bought https://www.amazon.com/Smraza-Raspberry-Heatsinks-Adapter-Switch/dp/B07CDDGVK7/ref=sr_1_3 (simple fan), this is an awesome kit (really, the fan is silent and the power supply seems good too), my 1.5Ghz rpi3b+ don't go over 51° with it, but it has stability issues obviously unrelated to temperature though (good thing : it never happens when i play 2D games, which is what i do most).

I am just going to use this case instead for my Pi https://www.amazon.com/dp/B071CNS4QQ and this is what i am using right now just i have an older case i am going to put my old Pi into.

Just wondering but do i have to format my SD card and flash it again cause the SD card i have in my Pi right now is running RetroPie 4.4 but of course it is in a Pi 3 and not in a Pi 3 B+ (cause i just ordered right when i am writing this the Pi 3B+)
-
@ecks You just need to make sure your system is up-to-date before moving the sd card.

I read half of the answers here and most are about cooling and fans. Thats why I want recommend something. There are cases out without a fan, but the whole body of case is the heatsink. I use one with my Pi 3 non plus and I overclock it highly without any heat problem and operating very stable. The main reason I say this is, there is no need for a fan. I am a fan of silent operations (... Lol^^).
But I must admit, I don't know if something is out for the Pi 3+. So apologies if not, but I wanted show you this road too.

Same, but the fan in the kit i recommended is silent. Perhaps you can hear it if you put your ear less than 10 centimeters away, but at 1 meter i can't.

@barbudreadmon Ok, I just had bad luck with my previous fan, which was loud as a jet! It was the loudest fan I heard in my life (i use pcs since 2001).
If its really quite and cheap, it may be worth it. Especially because I could use a different case if wanted.

Yeah, i had bad experience with some fans in the past too, but i gave this one a try after reading some reviews, i was surprised by the result (my overclocked rpi3b+ won't go above 51° with it), and i'm running it at 5V which is the highest speed in the manual.

My RetroPie version is up to date right now i just made sure of that today and also all fans for those cases (cause mine if you saw has the same kind of fan) which is silent.
Also hoping that tomorrow or Monday i will get my Pi 3B+ in the mail so i could set it all up and then overclock it to 1.5 GHz and try out Killer Instinct on it and i mean the Mame version and i noticed as well that PSP and Dreamcast games are a lot more stable on it as well. -
So i just got my Pi 3B+ in the mail today and tested it out which it was able to play certain games better and also overclocked it to 1.5GHz which i find stable and this is the average temps i get when playing a game
which it isn't that bad and i was playing Crisis Core (i was checking the temps when i was in a loading processes and also this is the max temps i am getting while trying to install Mame2016 
cause it takes so long to download/install. -
Hi guys so i have a question because right after installing lr-mame2014 i started to get low power warnings which i wanted to know if installing that would of started giving my Pi some problems?
-
@ecks You need a good power source, the 3B+ model is more sensitive to under-voltage. This is not a software problem.

Well the second i removed lr-mame2014 i didn't get those low voltage power warnings again.
-
Oh ya i tested out Golden Axe: The Revenge of Death Adder (which was kind of slow on the Pi 3) and was more stable on the Pi 3 B+ but there is some sound problems but it doesn't move all slowish like it did before which is more enjoyable sadly Killer Instinct still wont work well the Arcade version and also Spider-Man the arcade game still lags a bit.
