AMD Ryzen 5 2400G gets delidded and temperature tested
AMD this week launched their Ryzen 2000G series of APUs. Guru3D yesterday reported that the APUs have thermal paste in-between the die and heatspreader, opposed to being soldered. Four cores don't run that hot, but since it has thermal insulation paste applied, it can be delidded to to gain lower temperatures.
Overclocker der8auer took it upon himself to grab a Ryzen 5 2400G and delid it. He then replaced the thermal paste and temperature tested the unit with before and after results. To delid the new AMD Ryzen G APUs series, the existing Delid Die Mate 2 (DDM2), originally designed for Intel IHS removal could be used.
Once he successfully delidded the APU he didn't go for direct die cooling, instead, he applied Grizzly Kryonaut + Conductonaut compounds, placed back the APU and heatspreader and continued his test runs. The charts below show the temperature gains at stock clocks and when overclocked to 3975MHz. Further overclocking at the same voltage was only stable to 4000MHz, 25MHz faster, not anything significant. In our review, we reached 3.9 GHz on the stock air cooler.

In the end he concludes that delidding can be beneficial for HTPC systems, which benefit from a small air cooler in a more compact chassis and this space. der8auer is marketing these Delid Die Mate units and sells delidded processors at Caseking, where he earns his money this way.

So, the amd jumped into the wagon of those who eat...you know what....AMD has chosen to "follow the leader"? Nice, and one reason less for me to take amd into consideration for my next upgrade.

What does it matter with these APUs? They are meant for HTPCs, office machines, and for those who desperately need to save every penny. There's little point in overclocking them (just buy a real CPU if you need power) and the default temps aren't disastrous. You shouldn't "upgrade" your current 4 cores CPU to another 4 cores CPU (even though Intel would have had you believe otherwise for multiple generations straight). We already know the real deal, Ryzen 2.0, will have soldered heatspreaders just like the first Ryzen. If you really were considering AMD as an option, that's where you'd be looking. But of course if you were already set on getting Intel in any case, naturally no fact would change your opinion.

AMD's APUs have used paste before. These chips are meant to be budget chips with low wattage (65W) so using paste is acceptable. Their high-end chips still use solder, like they should.

Can we get the Room temperature stated?
i live in California it can hit 120 degrees Fahrenheit here; id like to see how a processor handles a high heat environment as well.
Anyway, i thank the dude for taking the time to inform us we can delid and get some improvement off this apu.

still MILES ahead of what....you know who does what with their bird poop.
Good job AMD. looking forward to Ryzen +, i want to upgrade my haswell (which goes to thermal throttling regardless of which cooler i use)
