Overclocker der8auer has posted a video demonstrating the delidding process of the AMD Ryzen 5 2400G, and his findings on its effect on temperatures and overclocking headroom.

The full video is embedded below:

The results are interesting, but disappointing from an overclocking standpoint, as he was only able to increase his highest frequency by 25 MHz. Thermals were far more impressive, as the liquid metal used in place of the factory TIM did lower temps considerably.

Here are his temperature results for both the stock and overclocked R5 2400G:

The process was actually quite straightforward, and used an existing Intel delidding tool (the Delid Die Mate 2) along with a small piece of acrylic to spread the force against the PCB.

The Ryzen 5 2400G is using thermal paste and is not soldered, which enables this process to be reasonably safe - or as safe as delidding a CPU and voiding your warranty ever is. Is it worth it for lower temps and slight overclocking gains? That's up to the user, but integration of an APU like this invites small form-factors that could benefit from the lower temps, especially with low-profile air coolers.

I just dont understand de-lidding a budget minded APU. Most people are not going to mate these with a cooler that costs more than the APU.

Filing this under "cuz we can".

You can push a CPU such as a 4670K to 1.35V using only a 25 dollar Hyper 212 plus, after a de-lid. I know you can, because I've done it. Without the de-lid, even a $150 AIO wouldn't be able to keep it cool enough.

I've even de-lided an i5 6400, and took it from 2.7, to 4.4 GHz, on the STOCK cooler, hitting low 80s under prime. That's right. People severely underestimate just how effective de-lidding can be and how much money you can save on cooling by doing it properly.

I slapped my larger wraith spire on a 2200G. Cooler and quieter but about an inch taller.

Delidding for overclockers may heve some value it that's what you enjoy doing but for most the TIM will do fine for the majority of users.

GamersNexus even has a video where they try out a custom copper IHS and LM on a RR APU with an aftermarket IHS that's a little larger to get a few extra degrees saved. GN talked about the custom IHS's value for maybe those that want less fan noise and could use the extra few degrees saved to allow for a slower fan profile usage with less noise.

I guess for folks Building A HTPC around Raven Ridge if fan noise is an issue then maybe delidding can have some value there maybe alongside undervolting to try and get as much performance with the least amount of noise on an air cooled system.

I'd like to see more Undervolting benchmarks done on the RR APUs and maybe a more effective air cooler and larger fans and some low noise testing also with fans run slower after a delidding and LM application. Some folks enjoy tinkering and I hope that they will share their results here and at Reddit's r/AMD subreddit.

So often important questions seem ignoredor dont seem to occur to the IT press.

APUs beg for water, cooling as both processors are economically and conveniently cooled by one unit.

Yet my avid reading shows it to be an ignored topic afaik.

ARE APUs THE SAME DIMENSIONS AS RYZEN? ie can ryzen coolers be used FOR APUs?

IS THERE AN ACTIVE MARKET IN RYZEN LC COOLERS? If so, recommendations?

& BENCHMARKS PLEASE?

I should add, that the zen/vega apus have advanced, dynamic auto OC within TDP limits, based on input from many hundreds of temp sensors.

Cooling the apu alone, should result in no brainer OCs for better performance and longevity.

Further, I checked die sizes.

RR apu = 209.78 mm2

ryzen = 213 mm2

so apu is a fraction SMALLER and ryzen LC cooler blocks for ryzen SHOULD fit the apu fine.

Great news IMO.

Who would spend ~$100 cooling a $170 apu? You would be surprised.
