Ultimate Dual Fan for Pi3
-
Just ordered one of those dual fans. Ship date is about a month away though. :/
-
@rion That kind of cooling is cool but would cost you a lot more just for making that because what i was showing costs around 10$ Canadian and buying the copper plate with the heatsink that size and also buying the materials for that case for everything to fit because without it everything would just fall out of place would cost you about double.
-
Dual fan is now on its way, I'll post some info and pictures to this topic as well, once I start to build them in. I need to order that thermal glue too, but that's something I'll do locally to get good quality stuff. I propably need to cut one of the copper plates into smaller piece to fit into the GPU chip.
But about testing, I know that there is those stress testes that can be done internally, but can I monitor the temp at the same time ?
-
@dd-indeed ExplainingComputers has a good video on testing temperature with Rapsbian.
-
But that requires a boot to OS, right ? So basically, I could use another SD card with OS installed to do those tests and once I've done them, I can put the RetroPie SD back and it's ready to go. But, are those overclock configs saved only on the SD ? Meaning that I would need to use same setup for the benchmark as well.

@dd-indeed You can use putty on your PC to connect onto your Pi which will give the same terminal for you to put in your commands which you can play a game on your Pi at the same time the most powerful kind and see the temps on your PC which is what i usually end up using when i am testing out newer things like when i installed my single little fan with the 2 heat sinks,
-
Allright, that sounds reasonable. I have the machine now next to my PC anyway in a test bench. Gonna get back to this whet I get the kit I ordered.
-
Got this in the mail a couple days ago. It’s cooled my Pi 3 considerably. Cut temps by 10-15 degrees celcius, depending on what I’m doing. Quite happy with it.
-
I would recommend it only if you're going to overclock your Pi, else it's not really needed.
-
It has other purposes than overclocking.
If you have a case that runs hot, this will help. This is exactly why I got it and it’s been great. Can finally keep the lid of my case on.
-
@livefastcyyoung Yes, not to mention the fact that if you are running emulators, or ROMs that push the limits of the Pi3, I noticed an immediate difference in just adding a heat sink. Any cooling, whether active or passive will be of benefit if attached correctly.
-
I should get mine finally next week, I decided to go with regular thermal paste instead of that thermal glue. I've been thinkin about, that I could just use hot glue gun to lightly glue the kit down from the sides. It would stay still, but would be also easy and safe to remove later. I'll post pictures of how I went with it later on.

I had only once heating problems and that was during a hot summer day, I;ve took the top cover off. The thing I don't like is that these heatsinks are way too small because of the cases. You can use a 40mm 40mm heatsink with a fan but you have to "mutilate" your top cover.
-
Laugh away, but she plays quake 3 arena all day without going over 45C, and thats in a 28C ambient temp.
It sure not a space saving design though. -
@spruce_m00se I'm not laughing. That's great. Did you power the fan externally? USB? or did you pull it from a 5v rail pin on the Pi? I would consider this myself.
-
Its a 12v fan, I have a 12v supply in the arcade cabinet that runs the RGB mood lighting and will soon run the car radio im going to use to augment the "jukebox" functionality as thats what I use most, I have the 12v supply on a relay board controlled by an arduino that also controls the power on and off of the tv and the volume, it will soon also power down the pi via gpio. the plan is to add temp probe to control the fan and I have done initial tests with a micophone to auto adjust the volume so that when one rom or song is louder it will auto turn it down.
but yeh the fan is 12v in a 3d printed duct
-
@spruce_m00se, i would do the same thing if i had an extra fan
-
just buy one then, they are like 5 usd........
-
That's not laughable, it's a must-to-do in very demanding processing and heavy overclocks. Besides, those big fans are quieter than smaller ones and it's easier to find replacement fans in that size. In arcade cabinet, the size not a problem either.

You do know that most cases out there for the Pi tends to have cutouts for the GPIO and for the LED touch screen and for the camera and yes i know not all cases has it for all 3 of them but still proper ventilation and besides that.
Also when people buys a fan for any system they don't buy them for overclocking purposes they mainly get it cause one they like to have less than 60°C and two they read their manual before even setting up the system and found out going over 80°C voids the warranty which if there is a problem with the unit they would not be able to return it for that purpose.
