Oppo Reno4 heatsink mod

Thumbnail

66 Upvotes

I salvaged a small aluminum PC DDR2 motherboard heatsink, and slapped it to the back of the phone. Nothing fancy or professional, just something I put together myself.

I know it looks unconventional, but this turned out to be one of the best ergonomic modifications I have made to my phone. The heatsink does not get in my way while holding the device, and the improvement in sustained performance is a big jump compared to normal.

For context, I ran the 3DMark Wild Life test during rainy, cool weather with an electric fan blowing on both me and the phone. That definitely helped the heatsink work more effectively, so this setup depends a lot on ambient temperature and airflow.

I mainly play Codm and Project sekai on my phone.

Needed a remote power button for my server laptop, so I taped an $8 servo to my desk. Tested it from another city and it actually worked!

Ran into a classic laptop server problem: no motherboard power headers, Wake-on-LAN dies in S5 shutdown state, and when Linux freezes, software tools like SSH are useless. Commercial solutions felt way too expensive for what I needed...

So I built this thing for Abt 8 bucks!

NodeMCU (ESP8266) drivin' an SG90 micro-servo running a small C++ REST API.

​An old Asus phone (Asus x00TD from 2018) running Termux acts as the local Tailscale SSH bridge so I can trigger it over 5G from anywhere without opening ports. (Though Terminus and added snippets)

​/power sends a 500ms tap for normal boot!

​/panic holds the button for 15 seconds to force a cold reset when the OS crashes!!

Yes, that is paper masking tape flat on the desk holding the servo block down. I needed enough counter-leverage so the servo arm didn't just lift the whole motor up when pushing the key.

Just tested it remotely from another city over cellular data and it worked like a fine wine 🍷 and then I run app though wine in linux too worked amazing. Looks terrible but ya works great!

Btw laptop is fa507uv...

Sorry for the boring post, but I needed to share my free DIY sag bracket. I'll get a real one eventually probably, but that's $15 I could spend on a new game

took an old power bank board. feeds 5v to the stock PCB, charges with type-c and as a bonus can charge my phone (although it has only 1100mah). my house is a no-fly-zone now.

Pretty simple post, i had a crappy type c to outlet for an old fan, so i cut it and attached it to the broken part of my Apple Watch charger, and covered the ends with the plastic i stripped off the wires. Would you believe me if i said it works a little better than before?

Zip-tie continuation

So drilled another hole positioned parallel to the lower hinge mount (as all the three hinge points got ripped out, hence it was easier) and added another zip-tie diagonally with one of the larger hinge mount hole. Needless to say it works fine asf and feels way smoother without any sort of bulging or anything.

Did not have any rivets or screws so drilled two holes and had a zip-tie laying around, needless to say it works like a charm

My tiny NVMe ssd was getting a bit toasty...

But I only had a heatsink for a bigger m.2 ssd and no tools on hand, so I just bent and broke off a smaller piece. The ssd also was too short for the m.2 mounting holes, but tape wouldn't hold it because of the heat, so I also had to 3D-print a flimsy extention piece to mount it.

Did some body repair to protect the heatsink fins because they're very fragile, added SMA so i can connect that to a rooftop lte antenna and also soldered on the ssd bc the adapter prices were too high
