Xbox Series X Thermals, Power, & Noise Testing: Cooler Design Analysis & Break-Down

video description

Rating: 4.0; Vote: 1
The Xbox Series X thermal testing looks at memory, SOC (CPU / GPU), and VRM temperatures. We're also benchmarking power and noise levels for the Xbox, including a partial tear-down. Console testing methods piece goes up separately - we decided to add some more detail to it, so it's referenced in this video as being live, but we're going to add a bit more and upload tomorrow or next day. This benchmark of the Xbox Series X includes a partial tear-down to help show the construction of the cooler. We also referenced a clip from TronicsFix (linked below) to talk about the vapor chamber design and how vapor chambers are constructed. The vapor chamber's pillars are obvious in the tear-down footage, so we show some factory floor footage to show how vapor chambers (like those found in the Xbox Series X) are made. We left our heatsink attached to the PCB, as we didn't want to disturb the thermal paste; however, since most of what we're measuring is flip-chip BGA packaging, the silicon is actually closer to the reverse side of the PCB than to the top of the case for MOSFET and memory modules. This is useful and convenient for measuring thermals with minimal disturbance to the cooler assembly. Disassembly is fairly easy and the Xbox mostly resembles a small form factor PC (e.g. mini-ITX / SFF box), except packed into an extremely dense, small assembly of parts. That makes for interesting thermal testing and analysis.

It's nice to see that Microsoft seems to have designed a relativelty quiet and cool running console here. I know that people who care about exclusives will be more excited by the PS5 but for me this seems like a much better deal when you factor in that it is able to emulate previous consoles where the PS5 is not. For me, exclusives are rare enough that it doesn't really matter too much and I am willing to wait for those games either to be ported over or to be able to emulate them.

Honestly I still really like the design of this thing. Its a basic, clean, and space efficient design, whereas the PS5 is a big flashy inefficient and complicated cooling setup by comparison as far as I'm concerned.
Also, the less dense fin stack feels to me like it will last much longer before getting clogged with dust, and blasting air into the top every once in a while might be enough to keep it clean. Not perfect, I feel it could be much worse.

Narrowing of the exhaust is predicted by Bernoulli's Principle, I suspect the concave top has little effect. You may not have noticed it in other cooling solutions because the flow wasn't as fast or coherent. You'd likely see the effect even if you modified the top to be flat.

Even with such strong disclaimer I can't stop my brain from trying to compare the numbers between the consoles. arrrgh.
Anyway, that's a megaton of testing and insight for the consoles. Keep up the good work, and hope this video doesn't get used as a fuel in console wars...

With the load under 200 watts and cooling never getting past immeasurably quiet , it sure seems like there's some performance being left on the table. Go figure, the one time we get an AMD part with an X at the start AND at the end of the name, and it doesn't allow overclocking!

Ok so the negatives are just that it has negative air pressure and no dust filters. That s pretty good. Runs quieter than the ps5. Which was a given as bigger fans make less noise. Wonder tho how loud the disc drives are compared with each other.

Why do you take the fun put of everything. And how bored are you to test heat. Weird as hell. Like play a game. Get somewhere where it's plenty of explosions and super fun as graphics. Like who cares long as it works

It's nice to see Microsoft focusing more on function over form, now if only they could take their experience with basically making a mini-itx PC and start making actual mini-itx PCs that don't go super nova
reply

It's sad that the idea of dust filter would be revolutionary for consoles.
Anyway thanks for the vid. I was lucky enough to get the X version of this GamePass machine, and I'm enjoying it.

Microsoft engineers did a really great job with this console I find the design practical and elegant at the same time. It s really cool the way it all comes apart snd goes together!
