Copper is not only a good conductor of heat, but also of electricity. Be extremely careful not to cause a short circuit. I would listen to the tips of the previous speakers. They have already done such mods successfully and they work. My fan mod is relatively easy to build and keeps Homey’s CPU below 40 degrees even at the current temperatures. ![Screenshot_20230715-072126_Chrome](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/6/c69cdc18cac457a31a09ef5f2a03aa8ca7e711b7.jpeg) ---

FYI - installed new [heat-sink](https://www.aliexpress.com/item/1005003955915167.html) on my heavily loaded system and also put thermal pads on memory chips + **it’s possible to close the top part** , which is great (I like the HP23 design) ![obrazek](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/b/5b644b6b2529fd22bd700d7eb9f30b1813ce3827.png) (note the last section) ![obrazek](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/5/f5ed17d609a830572adcc932d3a469a1d0f203e6.jpeg) ![obrazek](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/8/48f213f39558ea5ac65854ebdd2c3cc6fe344aba.jpeg) Used this heatsink : [https://www.aliexpress.com/item/1005003955915167.html](https://www.aliexpress.com/item/1005003955915167.html) **However please note I had to modify it - the cutout for BT+2.4GHz antenna must be much wider !!** The bad heatsink with **improper** cutout : ![obrazek](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/b/cbeaa368ac814ea656316d0a106d4dec51b810dd.jpeg) The good (original) : ![obrazek](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/6/9645372d620e56db5d2bc2eb4e0931e8b70c6b81.jpeg) Probably next step will be : [https://www.aliexpress.com/item/1005004355749568.html](https://www.aliexpress.com/item/1005004355749568.html) ![obrazek](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/1/e1439f9f3101b37684ca3d7fae003a79ae3b9a18.jpeg) or [https://www.aliexpress.com/item/1005003237704129.html](https://www.aliexpress.com/item/1005003237704129.html) - the maximal height seems to be 11mm (10mm with fan) so that you can still close the top part. …but this will require again soldering of the carrier board as the threads can’t be inserted in reversed way. Also it’s a question, where to connect FAN, probably will do some research around but maybe someone know ? Possibly in the way it can be controlled ? 😉 ---

For the ones who want to cool down their homey and don’t want to open it, this is also an option I have printed a stand to raise the HP2023 a bit so air may also flow underneath the homey, and then I have placed a cheap USB-powered fan next to the homey ![20230727_064940](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/6/b65193d4f940d17d7a24a33a936d7ec091bf5e32.jpeg) With just this extra airflow it’s cooled down for about 10°C ![Homey_Temps](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/7/67b39c5e4e42196ca0880047e49b363d8e822c3e.png) ---

Finally my cm4 arrived from official Digikey 😅 So excited where to start the modification. I plied open the open homey lid, after monitor a few hours, I see without lid it can drop about 7 degree Celsius, hence a much bigger heat sink will job without a fan. I wonder 🤔where is the portion of the antenna not cover when i get a huge sink approximate 11mm, drill 4 holes using bench drill. 😅 ---

> [@Shiki](#): > > where is the portion of the antenna not cover Not sure what you mean - you mean the required cutout ? Honestly, with larger heatsink, it’s a question if external antenna is not a better solution (when you connect external antenna, it needs to be enabled in config.txt.) ![obrazek](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/1/e123a200f5acf8894af74556f9c90bd46cad1d3d.png) ```auto The selection of internal or external antenna is done at boot time using the config.txt file, and can not be changed during operation. The config.txt options are dtparam=ant1 to select the internal antenna, or dtparam=ant2 for the external antenna. ``` > **[cm4-datasheet.pdf](https://datasheets.raspberrypi.com/cm4/cm4-datasheet.pdf)** > > 9.98 MB ---

Btw, does your Ethernet adapter is also heating so significantly ? When you touch it, is it cool or hot ? So scientific measurement is required… ---

Hmm, I think that it is old information; but I see now that the USB website script is changed. The backup tool is now working (also on the CM4 modules with more flash storage). It looks like that it is retrying when it is stuck. (The progress indicator is stopping but resuming after some seconds.). 👍💪 ---
