Pi 3 B+ Question
-
Hi i was just wondering if i was to get the Pi 3 B Plus would using the dual fan cooler work on it cause i am thinking of picking one up cause of the better stock clocks and the fact that the internet would be a lot better.
Also would i need to make a new image or could i just use the image from my Raspberry Pi 3 B and another thing i would like to know is does some games work a little better as well cause one game i still love even though it does lag a little on my Pi (but is playable) is Ninja Baseball Batman. -
@ecks I don't know about the cooler/fan, but for the 3B+ model you need the latest RetroPie image, it will not work on older images.
-
@ecks if it has heatsinks for it, it definitely wont work. And wth the poe pins the fans might not fit right.

Right now on my Pi 3 B that i have it is on 4.4 because i do try to keep mine up to date and also this is the cooler i am referring about which i don't know if it will be good for that Pi
-
Just need for someone to confirm if that cooler would still work on the Pi 3 B+ because i don't want to buy something if i have to buy a whole new cooling solution.
-
@ecks I don't think two fans would make much of a difference. The only chip that needs cooling is the cpu/gpu chip. Also two little fans like that can be quite noisy. I opted for 1 fan (120 mm :) ) which made a BIG difference and I can hardly hear it. (Does need a separate power supply though.)
But I don't see why the dual fan wouldn't work on a 3B+. -
@bobharris Just so you know i am using those fans right now on my Pi 3B non plus right now and i get an average of 40 degrees that is when i am playing my PS1 games and also 120mm is too big for a single board computer.
Also i do not hear the fans at all cause of the case that i use for it as well which you can see it is pretty much a generic case and also using a power supply for a single fan to cool down your Pi is overkill as well which you could of spent 12$ for this which i have used that case and cooler before giving it to my cousin which on full load you get 47 degrees on average and going lower than 40 degrees anyways is pretty much pointless.
Also the 3 B+ board is slightly different which is why i am overall asking about that because for the 3 B+ the CPU has a heat spreader on it which makes it a little higher which makes me wonder if my cooler would be on the CPU and GPU. -
@ecks Well then you're lucky. I used a small fan + heatsink on my Pi 3B and still got 60 C for PS1 games and higher for other systems. With my new setup temperatures fluctuate between 40-45 C. There is no such thing as overkill, it just depends on the goals you set. I want my Pi to last for a very long time, so the cooler the better. And I don't want to hear the fan, so bigger is better.
Also if you already own the dual fan, then why don't you just measure how much space there is left for the heat spreader? I doubt you will come across someone here who has a 3B+ and the exact same fan as you. -
@bobharris You'd be surprise cause that fan is very popular and for the small single fans for the Pi if you did place it in the right GPIO pins you would of always been in the 40's temp wise because bigger doesn't always mean better as well cause honestly if i wanted to use 120mm fans to keep a system cool and use RetroPie i would just spend 60$ on an actual computer using a Core 2 Quad Q6600 with a GTS 250 with 4gb DDR2 memory.
Also if you don't have heatsinks for your CPU/GPU/Memory then that is the main reason why your setup would get too hot as well because remember that cooler i linked is a heatsink with fans which you always need something to absorb the heat and able to cool it down so if you rely on only using a fan without heatsinks then you have some problems there. -
@ecks I'm just telling what I've seen. Anyways, good luck finding an answer.

@ecks I doubt that fan will fit the board. Check out where the 4 new PoE pins are... they'll block the fan from mounting:

So pretty much using heatsinks and a mini fan instead i guess then.
-
Oh ya do some games actually play better on this as well because so far i have seen PSP games running a bit smoother than before with the non plus models if anyone has tested this out if not when i buy one the games on the list that says not playable or has a hard time will gladly give it a go and then help update the list.
Also would be cool if i could play the first Killer Instinct game on the Plus model cause i tried on the non plus which it does run but little laggy (also my Pi is overclocked at 1.35GHz) in which i would be more than happy enough to test it out overclocked as well. -
Just use a Flirc Case and cool it silently.
-
@pi-mania I second this (for a stock Pi). I've got a flirc case and a Pi 3B+, albeit I'm using the flirc case with my 3B at present. Terrific case. Flircs are being sold with pads for both 3B+ and 3B now, so it should fit well.

@ecks If you arent overclocking then you dont really need a fan. No point in having the extra moving parts + added noise if its not needed. The raspberry pi3 b+ can safely operate to 70C before the system will even start to down clock to cool itself. The raspberry pi foundation have done extensive testing in this regard and have set the limits there for a reason. Your pi does not need to run at 40C all the time (if it did they would have set the cpu governor to kick in at that temp). If you are doing extreme overclocking then I would recommend a hefty heat sink (not those dinky little 14mm heatsinks). The one that comes with Super kintaro SNES case is awesome, not sure if they sell it separately though. I can run quake 3 on my heavily overclocked RPI 3b all day without ever breaking 70C. If you feel you must have a fan then I would look for option where you can set the fan to switch on and off at a certain temp (the super kintaro 9000 has this option as part of its shutdown script). Just my two cents for what its worth.

You do know i said i overclocked the Pi i am using now and i do intend on overclocking the B+to at least 1.5GHz and i do prefer having my Pi cooled down just like i do my desktop as well.
Also the heatsink for the Super Kintaro will not fit on the B+ and you will notice from this image
And you can see from the image and the way the B+ is the 4 pin connector is in the way.
Would also like to mention that having the Pi cooler than 60 degrees feels better and there is no actual noise from the fan but hey you like owning something that gets hot i get it just not everyone is the same which is why people does end up buying these fans for their Pi's.@pi-mania said in Pi 3 B+ Question:

I actually don't like the Flirc Case at all thanks.

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.
