    While true for the component itself, there’s material difference for any caps surrounding it. Sure the chipset would work fine at 40, 50, 70°C. However electrolytic capacitors lifespan is halved with every 10°C temperature increase. From a brief search it seems solid caps also crap out much faster at higher temps but can outlast electrolytic at lower temps. This is a consideration for a long lifespan system. The one in my case is expected to operate till 2032 or beyond.

    I don’t think other components degrade in any significant fashion whether they run at 40 or 60°C.

    It’s a Chromecast with Google TV (CCwGTV) wich itself is a dongle. It’s connected to a Plugable USB-C PD hub - another dongle. The white bit sticking to the left from the hub is a TP-Link UE300 Ethernet adapter - yet another dongle. Finally there’s an SD card inserted in the Plugable hub as well as an HDMI coupler hooked to the other end of the CCwGTV which allows connecting an HDMI cable to it.





  • So generally Pegatron. :D I used to buy GB because it was made in Taiwan when ASUS became Pegatron and went to China. Their quality decreased. GB used to put high quality components on their boards in comparison. But now GB is also made somewhere in the PRC. I’ve no idea where MSI are in terms of quality. We used to make fun of them using the worst capacitors back in the 90s/00s. Looking at their Newegg reviews, their 1-star ratings seem lower proportion compared to Pegatron brands and GB. Maybe they’re nicer these days? The X570 replacement I got for this machine is an ASUS - “TUF” 🙄

    Hard to say. She’s been in 24/7 service since 2017. Never had stability issues and I’ve tested it with Prime95 plenty of times upon upgrades. Last week I ran a Llama model and the computer froze hard. Even holding the power button wouldn’t turn it off. Did the PSU power flip, came back up. Prime95 stable. Llama -> rip. Perhaps it’s been cooked for a while and only trips by this workload. She’s an old board, a Gigabyte with B350 running a 5950X (for a couple of years), so it’s not super surprising that the power section has been a bit overused. 😅 Replacing with an X570 as we speak.
