yeah, I know, that poo poo rots your brain, of all the places on the internet this is probably the place that takes him least seriously, it just drives me nuts it is curious how the "leaks" of zen2 clocks happen to exactly match coffee lake clocks, I wonder if youtubers think zen2 can break 5.4 ghz now that toms said a thing Paul MaudDib fucked around with this message at 15:46 on Mar 27, 2019 |

on topic I've heard that power strips degrade in their ability to arrest surges over time... I've had older strips that probably didn't trip (that PC died in a probable lightning storm even though it was on a (cheap) strip). Most of my important gear is on a couple nice perfect-sinewave UPS, is that not safe / is there an arrester strip that I can buy and rely on to not poo poo out in 3 years? If so I don't mind spending $100 on a power strip like that but not sure if that's snake oil. Paul MaudDib fucked around with this message at 16:00 on Mar 27, 2019 |

yeah makes sense, I'm not laying in big copper grounds as big as my finger, so there's nowhere for a lightning strike to go. It's just that nothing blew up except the stuff on that one old strip

I mean, they do loose effectiveness over time, and I think distant lightning can cause the kind of surges they protect against, but I don't think I've ever had a thing die from a power surge so I don't even bother anymore. You can get higher-end surge protectors that tell you when they don't protect anymore if you want, I think Wirecutter has a rundown.

The one time I had stuff fry the entire house shook and I was seeing spots for several minutes from the flash. It came in over the coaxial into the modem and out over the network. Every single NIC was worthless, the Cat5e still works 5 years later and we didn't bother rerunning it since it was working. All the hardware is still working too. Just slapped some PCIe NICs into the computers and set game consoles to wireless.

is there any merit in making my computers not the path of least resistance on ordinary surges, or is that something a decent UPS handles fine? like again, if it's $100 for a surge protector I'll never need to worry about then fine, that's worth it, but if not then w/e. and yes you need to watch your cable drop, a lot of high-end UPSs/surge protectors will protect coax, my parents seriously used to have a cable that was the highest point and we'd get fried multiple times a year until the cable company grounded it properly

I have an APC SurgeArrest Essential (PM6U model, but in Europe, not sure if it's the same in USA) which is supposed to be one-use only: if it gets hosed up by lightning it will just stop working completely and you'll have to buy another, so you're safe in knowing that it works. It also has a malfunction LED to see if anything's wrong with the strip. Considered I paid 15€ for it on sale (it's 30€ normally), I'd rather replace it in case of disaster than have it protect me once, forget about changing it, and getting screwed by the next lightning frying up to 2000€ of electronics. (though our local grid is fairly modern and works nicely, I do remember some greyouts and surges from when I was a little kid 30 years ago, but today it's exceedingly rare) I have no idea if there are any comparable UPSs though, my work computer is a laptop so I definitely don't need a battery backup for it

When I went looking into it a few months ago I couldn't find any hard information on the danger posed by ordinary surges, just a bunch of rote recommendations to use surge protectors, so  If anyone does have better info I'd be very interested as well.

Most of the UPS's you see these days are going to be passing through line power when its normal and cannot react fast enough to a lightning strike influx. They all have some manner of surge arrestment from my experience similar to what you get in your power strip, but since its a built in part you're probably better chaining a second strip that you trust off the back of it (or in front of the UPS might make more sense now that I think about it)

Decent UPSes show when it's time to replace them. The engineers I hear from say that there's only so much you can do when it comes to a lightning strike, and the worst thing you can do is get a surge protector with a false sense of security. Surge protectors etc seem a lot like soft bicycle helmets; they're meant to eat the brunt of the blow and break to keep your computer from taking damage. Still important to use them, just don't take it to mean you can get away with whatever. The Wirecutter had some recommendations, but they're pretty garbage at factoring in long-term stability.

Just slapped some PCIe NICs into the computers and set game consoles to wireless. I had something similar happen. A lightning strike came through the coaxial line upstairs and took out the cable modem, the PSU and the onboard NIC. Popped in a new Intel PCIe NIC (which turned out to be far superior to the onboard Realtek NIC) and a new PSU and kept on trucking. Everything else still worked. Come to think of it, I really need to get a UPS.

I ended up buying this Tripp-Lite unit since it seems to be generally well regarded.

There's a big difference between a surge of the type you'd possibly see when the power comes back on after an outage, and a sudden spike from a lightning strike. Surge protectors are designed to mitigate the former, not the latter.

A good UPS and a good power supply are the best things you can buy to extend the life of your components. A good UPS will last through multiple builds and if it prevents one component from burning out it paid itself off. Xae fucked around with this message at 19:20 on Mar 28, 2019 |

taqueso posted:It's the opposite. https://electronics.howstuffworks.com/gadgets/home/surge-protector.htm quote:The most familiar source is probably lightning, though it's actually one of the least common causes. When lightning strikes near a power line, whether it's underground, in a building or running along poles, the electrical energy can boost electrical pressure by millions of volts. This causes an extremely large power surge that will overpower almost any surge protector. In a lightning storm, you should never rely on your surge protector to save your computer. The best protection is to unplug your computer. quote:On the other end you have systems costing hundreds or even thousands of dollars, which will protect against pretty much everything short of lightning striking nearby.

https://en.wikipedia.org/wiki/Varistor#Composition,_properties,_and_operation_of_the_metal-oxide_varistorquote:While a MOV is designed to conduct significant power for very short durations (about 8 to 20 microseconds), such as caused by lightning strikes... A MOV isn't going to protect anything below a couple hundred volts, which is what I original read your OP as saying they would protect against, but clearly you just meant lower energy surges than lightning. And of course nothing will protect your stuff if somehow the lightning hits it directly.

My great-grandfather nailed a copper wire in a tree and tied the other end around a metal beam on my grandparents house so he could dry out grape leaves. Lightning, of course, hit the tree. It traveled over the wire and caused the AC machine in the attic to explode in a fireball.

It simply arced across the gap. yeah that's why I realized why even a fancy specialty powerstrip probably wouldn't work, if that kind of voltage can arcover a purpose-built utility substation interrupter then what chance does a power strip (even purpose-built) have against a 300kV-3MV lightning strike. This is something like a 50-500 kV disconnect: https://www.youtube.com/watch?v=GMbN9nb3qyk I mean a lightning bolt isn't continuous but that presents a whole separate set of challenges, you can't quench the arc fast enough to actually cut it off in time to prevent damage, and lol if you think a half inch breaker or whatever is going to be enough isolation when that's the arc that forms. Even if you had a fancy pneumatic breaker that blew the arc out it would still probably not be fast enough to save your PC. That said you're still stupid not to at least have a basic UPS or something on the equipment, yeah if it protects one decent line surge in 10 years you've probably made your money back.

Cooler recommendations for a Ryzen 2700x? For the past five months I've just been using the Wraithprism heatsink that came with the chip, but it's running hotter than I'd like it to on some games with a modest OC of 4.15ghz. This is for an ATX case with plenty of room so I don't think space will be an issue.

The standard answer is usually the NH-D15S (remember to get the version with the included AM4 mount kit).

It showed sweet spot in the mid range where the U12A was close but still a few degrees behind the D15(S). The D15(S) was more efficient at very low and very high fan speeds. U12A temps didn't seem to go down past a certain point, it just got louder.

Yeah, it's actually important to note the new fan, which is simply better in every way. I have to try to forget about its existence, because I already have a case full of older Noctuas, which are just begging to be changed out for the new hotness
