So I’ve cut my PCB manually (slow but less likely to make a mistake)  
Small hacksaw for the accessible side and a blade (wearing a glove) for the other.  
I marked up with a Stanley knife, the lines were easy to see, whilst cutting. Make sure you you’re exact with marking as not to cut too much, there is little room for error. Just waiting for the upgrade kit to be put on sale so that I can do the same on my productive V5 Kit.  
I hope this helps others….

I have a PI5 with the same heatsink with fan. Looking at your pics it’s telling me what i was afraid of. No space between the board for good air circulation. How tight is it? Thanks for those pics.

It’s not touching the PCB and not shorting on the IC underneath. Don’t forget that there is a big hole as well. Also the PCB will not be resting on my case, so with extra space. I haven’t tested properly yet, I may use the (yet to be offered) zynthian cool block as I’m using an old network metal switch housing as case. Feel free to ask questions I’m happy to share my experiences and future pictures.  
Pictures….

Update Temperature…

I’ve run my converted V5 main setup, in a cardboard box, for a while now and with just the Dexed snapshot loaded it was reaching 53C and no cooler running ⁉🤔

I’m experimenting with the config.txt temperature settings taken from an answer in this link

> <https://raspberrypi.stackexchange.com/questions/145927/raspberry-pi-5-edit-modify-temperature-limit-for-the-active-cooler-fan>

To edit the config.txt file I’m using the webui  
Hardware \> Options \> Advanced View \> Custom Config

First test takes me to 33C

```auto
dtparam=fan_temp0=40000
dtparam=fan_temp0_hyst=10000
dtparam=fan_temp0_speed=125

```

@jofemodo I know we don’t like fans 🫣

Hmmm interesting.  
I started looking at thermal blocks just in case.

Dumb question for @jofemodo and @riban:

Is active cooling disabled by default in Oram stable, even if custom Rpi5 builds are detected?

In that case, I would not dislike the possibility to set it on over a certain temperature, just to see if the Pi5 holds better with maximum overclocking.

Regards! ☺

It’s not looking good. I see some heat sinks but they look big. I don’t have my V5 main board yet (on its way) so it’s kinda hard to picture it.

@Aethermind  
I’ve just rechecked it’s not disabled the default at 50C speed is 75 and it’s really quite 😅 too much rock music 🤘

I‘m at a constant 45-46C with Admin \> “Test MIDI” running many times over with the following settings

Thank you for checking on this @chrismat! 😀

So it is now ascertained that active cooling is enabled by Oram for custom kits. 👍

Cheers!

This case, offered on Amazon, provides passive thermal cooling through five “cooling towers”. I haven’t tried it.

Thanks  
I saw that one but i ordered the V5 legacy board to add to my own design. This will not work

Another nice video from @mr_floydst.

He’s the reason why i started looking at Zynthian

I was expecting this, since it was announced on Friday, with a video-short full of meaningful clues for us Zynthian users 😉

As you always do, super cool video, @mr_floydst !! Congrats and thanks you so much for testing the upgrade kit and validating the upgrade procedure!

We hope to offer the upgrade kit in the zynthian shop along the next few days! And as we promised, the price will be also minimal!!

All the best!

Are you still sending out the V5 to V5.1 minimal upgrade kits?

If so I got my Zyn about 3 months ago and would like to put a Pi5 under the hood. I don’t mind working with metal or PCB’s so this would work for me. If you need a bit of money to cover the bases let me know.

Thanks.

Hi V5 owners!

We have released the minimal upgrade kit for the original V5 kit, that allows upgrading to RPi5 as described in the post opening this thread:

> [@V5 Minimal Upgrade Kit](https://discourse.zynthian.org/t/v5-minimal-upgrade-kit/10076):
>
> Hi @zynthianers and specially V5 owners!! The V5.1 release is getting closer and i would like to offer an upgrade path for V5 owners. As i already commented here: releasing a “full upgrade kit” is “logistically complex” and really wasteful, so very probably we are not going to follow this path. In the other hand, the Minimal V5 Upgrade Kit is super cheap, logistically easy to manage and almost no wasteful, so i would like to follow this path. This path is harder and probably not many V5 …

You can buy the upgrade kit in the zynthian shop:

> **[V5 upgrade KIT](https://shop.zynthian.org/shop/v5-upgrade-kit-410?category=10)**
>
> This kit allows upgrading your zynthian V5 based in RBPi4 to the newer and more powerful RBPi5.
> 
> This is a minimal upgrade kit, with just the bare minimum set of parts required to do the upgrade:
> 
> \* Thermal block V5.1 for RBPi5
> \* Thermal pad
> \* DSI...

Yeahhh! price is quite affordable but please, note that some surgery is needed, so before ordering, read carefully [the instructions](https://discourse.zynthian.org/t/v5-minimal-upgrade-kit/10076), watch the video:

[![](https://img.youtube.com/vi/m11rKpsOq9E/maxresdefault.jpg "Zynthian 5.1: A very powertool update") ](https://www.youtube.com/watch?v=m11rKpsOq9E)

and ensure you have the required tools and skills.

Enjoy!
