Re: A question for all electronics-literate out there (12V-to-PWM-adapter)

You might find this doc useful. The other issue here is that PWM fans expect a 3.3/5V PWM signal, not 12V. There's a pull-up to probably 3.3 in the fan, so this way the mobo can PWM between ground and open with a basic 3.3V I/O and everything Just Works. This should be mostly solvable by putting ano...

Firefox usually reports this stuff in the order looking up X -> connecting to X -> connected to X -> transferring data from X.

Re: EPA vs. FCA (Here we go again!)

Yeah, having high compression and boost (high peak temps) and always running lean (spare O2 to turn to NOx) makes it tough. Lean burn on a 10:1 gasoline engine wasn't really even doable within US emissions regs until GDI, and that looks very tame compared to a modern 14:1 diesel under high load. I t...

Re: I need help planning cooling

This depends a lot on what you're trying to prioritize. For instance, since my graphics card should have about half the useful life of my other components, I don't prioritize cooling of my card itself so much as keeping its heat from bothering any other components. Also, how dusty your environment i...

Re: Upgrade itch

CPU load doesn't have all that much dependence on resolution. If the GPU can handle it, then don't worry about going 1440p. What you can do to isolate how your CPU is holding up is turn resolution down to something low like 540p and see where frametimes are at. Framerates in that context probably wo...

Re: RX480 Remorse for not buying?

I'd agree with Waco. There are use cases for which it matters, but most gamers have heavily overspecced power and cooling anyway, and gamers don't tend to use GPUs at a high enough duty cycle to make power costs a big deal. Overclocking's prominence shows how many people out there don't care. I'd bu...

The only proper drive I currently own (Sandisk X300) is at 9023. The SSD before it (Crucial MX100) probably got to at least twice that, but started bitrotting stuff. I broke it in half when it did that, so I can't really check. Before that was an Intel 320 that is still in use elsewhere and is proba...

Giant fans are also good, yeah. You need a lot of heatsink thermal mass to avoid the fan use on warm-up, but steady-state airflow isn't tied to heatsink area much at all. A particular exhaust temperature will create a particular amount of static pressure, according to how much less the warmed air in...

It's not so much about torque or torqueband shape as peak versus continuous HP.
