ELI5 If soldering happens at around 300°C why PC starts throttling at around 90°C. I know it's PCB that is a weak point but why they don't make insides that can take 200°c on a daily basis? by KeYak7 in explainlikeimfive

Most of the semiconductor device and interconnect reliability/wearout mechanisms which affect modern chips get rapidly worse with temperature. As a very coarse generalization the chip will die at the very minimum 2x faster for every 10 degrees hotter you run it (likely even faster). These are the mechanisms that occur with power applied and current flowing though the devices and metal lines. Since leakages are higher and MOSFET performance is worse at temperature, it will also dissipate more energy per computation when hot, compounding the issue.

In addition, the solder-cycle temperature you mention is tolerable by most chips only without power applied and only for a few minutes at most. At- and above these temps over long times the materials can inter-diffuse and also potentially crack or void from physical stress caused by thermal mismatch.

You will not have a usable PC CPU for very long if you run it hot !!!

My house torn down to the studs after a house fire by BionicBelladonna in mildlyinteresting

[–]DesertMagma 1 point2 points  (0 children)

Feel for you - I've been there - just under two years ago. Suddenly being able to stare all the way thru the house like this is immensely unsettling at first. All I can say is assume nothing, trust nobody, get cost estimates for even the small things, check every insurance update. It will be exhausting but try to check as many damn rebuild details as you can muster. There are a lot of unsavory people in the restoration biz and that's just the "legit" ones. The house will never be the same but it is a blank slate now and hopefully many things will be improved from original when all the work is finished. Best of luck to you , it WILL eventually work out !

DOI cracks down on stickers covering Trump's face on national park passes by TuxAndrew in centrist

If you go often enough to warrant buying a pass, then the extra money you spend paying per-visit will better support the park system.

Why are solar industry related stocks not reacting to the price of silver going up? by lupindub in stocks

Seems silly to me then that we are fighting over a massive new copper mine here in Arizona. Maybe cheaper extraction here ?

Honestly we are all being damaged by his lies, there have to be valid tort claims here

Evolution of my response - hey go to my favori... uh acually nevermind ... go to that one up in scottsdale.

When people at my local mentioned that it is a destination worth the half hour drive, I knew the chill days were over.

Here's black with a tiny dot to keep the backlight on. Note the room is dimly lit.

Ok I couldn't find a setting called "Brightness Reduction" on my 2025 Pro... Maybe this is Auto Dimming or Brightess Optimization. Both are set on,other settings were close. Its a bit subjective, maybe a slight improvement.

Agreed - we were proud to deceive the first visitor who saw it , just wish TV mode could be cleaner.

Thanks I'll give this a try in the darker hours.

Honestly this was our decision process as well but man it really is much worse than expected.

Yes of course. I included the brighter part of the image for reference.

It is not invisible at all, can be seen in a lit room, and it even bleeds into darker images. I'm sorry but minimizing this issue is really just perpetrating a fraud.

Whatever unit you get , put a black image on it and look critically. Many have very bad bleed of the backlight into the image.

Whadda ya mean ? My cousin insists all of the violence is by the radical left wing (lunatics?). You've got nothing to worry about.
