    Well, if I hypothetically decide to give it a shot and risk melting some expensive electronic doodads, how do I figure out what components are right for me, compatible with eachother, and where to buy them? Like I said, the last time I owned a desktop was in 2003, I really am clueless here

    pcpartpicker is a good place to start. it checks for incompatibilities and you can find parts

    bought a dirt cheap display model rtx 2070

    one of them cheapos with the non-A chips, 114% power limit

    ordered some resistors to see if we can change that, even though it's non-A the OC I can do under 114% power seems pretty promising

    So experimenting with fan control on my system, basically now im using coretemp again (so i get a nice quiet idle) but whenever there is a peak in load after a while, and the cpu itself is quite warm, the temps can jump high enough for it to be unstable..

    For example, going from 3.5ghz to 4.6ghz and then unpausing beamNG caused cpu temps to go from 50c to 80c, 80c it decided to not be very stable, beamNG froze intermittently and the sound was dropping out (to that lovely bsod sound).. but right before it bluescreened for good, the fan control had kicked in with max fans and managed to keep the cpu cool.. I feel like my CPU is like a nuclear reactor, just waiting to meltdown!

    I've had my first experience with Cougar products tonight, namely their 120mm Vortex PWM fans. They're very high quality and absolutely whisper quiet. Perform well as a nice little bonus... of course... they better for $18 a piece.

    Highly impressed and further fuel against the argument of "Noctua is always the answer".

    Noctua is great, but a lot of money with diminishing return on investment when there's other great fans for less. Where noctua shines is the crazy exotic fans, need a super slim fan with PWM in 60mm for some crazy reason, they'll have it

    See, if I compare the H.E.C CFV12HP (what I bought) and the Noctua NF-F12, the Noctua flows ~25% more air (93cfm vs 70cfm) but costs about twice as much and is a fair bit louder.

    I just don't see the circlejerk worthy performance out of them, especially for about $30 a fan.

    I've never used a Noctua fan, but whenever I have looked at fan benchmarks, they don't seem to be that much better than some of their competitors. So, depending on what you want out of your fans, there may be better options out there.

    That said, as a brand, there is value in the fact that all of their products are consistently up there.

    The only Noctua line I'd buy is the Redux, which are basically last year's tech in grey/black and way cheaper.

    I think the jist of noctua in mainstream is you get class leading performance, but at very high prices.

    But I needed a 40mm fan that supported the standard 4 pin pwm pinout but at 5v rather than 12 and with a shutdown feature when pwm is missing. Very specialist. Noctua happen to do it, they do a tonne of specialist non mainstream stuff

    well, everything went as planned, but i'm disappointed.

    it works, power budget effectively tripled, but i'm hitting board voltage limits that were roughly in line with the general power limits in the first place. at least i can run furmark at max oc now?

    there are of course other mods that could fix it... but i'm not about to bother doing that under air.

    I have identified at least one phishing website using a LetsEncrypt certificate for HTTPS. Just a reminder that a valid certificate and the browser saying "secure connection" does not mean the site is legit. A free cert may also be a red flag as scammers are often not willing to pay for either hosting or related expenses (many scams are hosted on free hosts).

    Yeah, I can imagine that becoming an issue with how prominently certificates are being displayed as meaning that a website "secure".

    That said, my own website uses a free certificate from cPanel :p

    Also note, there are many attacks that can strip certificates and reissue new ones, your browser will still show valid HTTPS with a green padlock, you won't notice until you highlight the padlock to check who issued the certificate and find it's not who you expect.

    I've been doing that quite a bit lately, and that's one of the ways I identify spoof sites. The cert issuer almost always sticks out. As an example of a trusted site using a reputable cert issuer there is BeamNG (DigiCert). I have also noticed that the scam sites which use HTTPS often have short-lived certs.

    I had a talk with someone at a computer store, they recomended I wait until the next gen AMD stuff comes out and get a current gen AMD processor then. Thoughts? What about brands in general?

    Depends? PC components don't typically go down in price much (if at all) when a new generation launches, since they tend to handle their stock levels quite well. However, its possible that with a prebuilt you might be able to get a better deal, same goes for laptops. That said, if the price drops only bring it in line with the price to performance of the new parts, you might as well buy the then current generation.

    But I think their advice to wait a little bit is probably solid. Since anything you buy now will be worse than what the same money will get you fairly soon. Even if you don't plan to go the AMD route, its rumoured that intel has price drops in line for when next gen AMD releases.

    Recently a client told me about his collection of various Risc-based computers. Interesting story. Anyone here familiar with these systems?

    Also, got another dead 15" MBP 2011 w/ GPU failure. So I removed the logic board and 'fixed' it the Frankenstein way using a heat gun..

    Cleaned (sort of)

    Professional BGA reball station (1979, colorized)

    Gradually increased the heat gun temp, peak at 220 degrees celcius, steady cooldown.
    Fresh thermal paste, reassembled, fingers crossed, and now it works as i type this text on it.

    Crackbook Pro is alive again. For now.
