Review: change of review - This is a second review of the product because it has worked flawlessly for the past 2 years. It is quiet and fulfills my need for a reliable desktop computer. I have limited space and no expansion plans, so this puny box has been perfect. I'm using windows 10 and I'm always getting the message inviting me to update to 11. Even though the message says my box is compatible with 11, I haven't updated it because I don't completely trust micro$oft.
Review: Cool but has a weird achilles heel - This is a great little PC, and it really fills a niche like no other product on the market. Being able to have a powerful PC in your pocket (or bag or whatever) is great, and I can run it in a window on my MacBook (with an HDMI to USB-C converter, like the Genki ShadowCast), giving me the utility of two computers with the footprint of - basically - one. However. I thought mine didn’t work at first, but it turns out that it will only work with the PSU it comes with, as it doesn’t support USB-PD; instead, it requires 12v to be delivered over USB-C without negotiation - something no normal USB-C PSU is going to do. So that all but rules out using this with existing power supplies, forcing you to carry two (you can’t use theirs for anything else for the same reason - it will cook anything else you connect it to). There is an option I’m looking into (USB-C PD “triggers” that you can put between a real USB-C PSU and this thing, and use to tell your PSU to output 12v) that will be a bit messy and a bit “enthusiast-level” / hacky, but it should work. Meantime, I’m lugging two PSUs around and being careful which one I use.

### ⭐⭐⭐ So far, so good. But I'm worried
*by K***S on June 4, 2021*

I bought this as a small PC for my entertainment center about 2 weeks ago. I was really impressed with it's speedy handling of Windows. However I noticed while running apps that the fan seemed to run almost constantly. I've since been monitoring the CPU temp and it swings from 60C to 95C regularly and twice I have caught it at 105C which is the top end for the J4125. I wasn't even running resource intensive apps. I'm worried that with it running at those high end temps so consistently it's only a matter of time before it fails. I'm going to try to replace the thermal paste and see if that helps because I'm really impressed with it otherwise. It's adorable and full of potential! Here's hoping!
