This is cta prime back here again today, we’re going to be doing a teardown on the gmk nook box. Jetzt, if you’re not familiar with this, i just posted a video kind of a full review running windows. 10. This is a palm sized 4k mini pc it’s got 8 Gigs von ram 128 An 512 gigabytes of storage right out of the box and it’s powered by the intel, celeron j4125 overall for its price and its form factor. I think this is an awesome performing little mini pc now, if you’re interested in seeing this thing in action check out my original video. But since then, i’ve had a few people asking me to do a quick, teardown so that’s exactly what we’re gon na do in this video. So first things. Erste, we need to pull the bottom off here, wie Sie gesehen haben, we have those four rubber feet, they’re kind of glued on. They have that sticky back. You need to peel them off and then we’ll remove these four screws. The bottom should come off of this fairly easily and once we get this off, we should be presented with the m.2 ssd that they have pre installed. Now this one is the lower end version with 128 Gigabyte Speicher, but you can opt for up to 512. In this unitand this is user replaceableso if you did end up with the 128 gigabyte model and want to upgrade it down the road, you can always do that.

You’Re just going to pull this screw out here and the m.2 ssd should slide right out. So they have made this pretty easily accessible and, Wie Sie sehen können, this is not an 80 millimeter m.2. Dies ist ein 42 millimeter m.2. Weiter oben, we need to slide the mid case off. This is aluminum here and i personally like the way they set. This up with aluminum it does offer a little extra cooling for the whole unit itself. Some of the other, similar mini pcs, are made out of plastic, and this kind of does up the build quality, adding this aluminum case here. Also, Wie Sie sehen können, this whole unit is comprised of two different pcbs. We have the i o board and the main board, and i love the way they’ve set this up it’s connected with a ribbon cable, and this is how they’re able to fit this in such a small form factor. The bottom board is what i call the i o board. This contains the usb m.2 slot and things like that and the upper board, which i refer to as the main board houses, the cpu ram, hdmi and power input. So as soon as i pull these standoffs out, we’re going to remove this bottom plate here, and we can now see that i o board, we have our rtc battery connected right here and there’s two ribbon cables that just need to be popped up. We can remove that.

I o board completely so yeah like i mentioned this houses, the usb 3.0 Häfen, das 3.5 millimeter audio jack and the sd card slot and on the bottom, as we saw when we pulled it apart. This has that m.2 slot so yeah. This is an awesome way that they’ve come up to keep the size down on these new units. So as for the main board, this is where all the magic happens. We have an intel, wi fi card here, 802.11 ac plus bluetooth, 4.2. It has two antennas connected to it and it just routes around the upper part of this whole pc and it actually has some decent wi, fi and bluetooth range. So now what i want to do is go ahead and remove the main board. We have four more standoffs here that need to be unscrewed i’ll go ahead and get these out, and this should pull right out along with the heatsink. Gut, ich bin, not exactly sure if the heatsink is attached here, it might just be attached to the upper case and it is attached just to the upper case. So let me go ahead and unplug these antennas here, just to get them out of the way, and once i have these out of the way, i can just remove the main board, and this has a lot of thermal paste on it on the original model that I reviewed they were using a little thermal pad, which didn’t cool very well and it actually had an aluminum heat sink.

But this one here they’re using thermal paste and a full copper heatsink so that’s. Why we have much better cooling on this production unit, really glad to see that they’ve done this, but they could have lightened up a little bit on that thermal paste, but i mean it did keep cool enough like it sits. I won’t add as much when i reassemble this unit, aber, Wie Sie sehen können, we do have that full copper heatsink in here and this does have a fan attached. This is not a passively cooled unit, it’s an actively cooled unit – es gibt, just not enough metal in here to keep that cpu cool without a fanand it looks like they’ve used a little of this tape here to kind of keep this heatsink in place. So we got that tiny fan with that full copper heatsink, and this actually does a really good job cooling, this j4125 cpu. I did some thermal testing and power consumption testing in my last video. So i was wondering why this heatsink was kind of taped in here. It was taped in here loosely, Aber dann, when i pulled it out completely, i noticed that it’s actually spring loaded, so these four springs make contact with the upper side of the heatsink to kind of push it down on that cpu and make full contact. This is just another little upgrade that they’ve added to the production unit. To keep this thing, cooler really glad to see this so yeah.

I love the way they assemble these little mini pcs. I mean there have been a lot of these little mini pcs or these palm size. 4K. Pcs released xiaomi has one the chewy lark box, the gmk nook box, which we have here and i believe, there’s a few other chinese manufacturers coming out with these same style. PCs – and they all use this stackable pcb layout here, but i mean this is a really good way to fit all of this tech into a super small form factor but that’s going to wrap it up for this. One really appreciate you watching, like i said i had a few people asking me about a quick tear down, so i figured i’d go ahead and create a video on it.
