I have fitted a Hyperpixel screen onto a Raspberry Pi 3 B+. You can see in the photo the bigger heat sink will almost come into contact with the back of the screen once I’ve installed it… will this cause any problems?

If it doesn’t touch, no problem. If it does touch that could very well be an issue. You’d then have to add a booster header, [https://shop.pimoroni.com/products/booster-header](https://shop.pimoroni.com/products/booster-header) and taller standoffs.  
Something like this would probably work [https://shop.pimoroni.com/products/premium-pi-standoff-selection](https://shop.pimoroni.com/products/premium-pi-standoff-selection). Screw the one with the treaded stud into one of the others with the two screw holes.

Thanks that’s really helpful. I have just tested and it doesn’t touch, there’s about a 1.5mm gap between the top of the heat sink and the back of the screen. I need to keep the whole unit small so want to avoid and booster headers.
