  • Trump is speaking mandarin and Harris is speaking cantonese.

    TRUMP: Maybe I should just reflect, and not speak more. I’ve been abandoned, do I deserve that? If I really was a bad shepherd, can I try again? Can I hold you again?

    HARRIS: When I look back, walking with you, I’ve never been happy.

    TRUMP: Too much hate, it’s no use. To bring up the past only torments us.

    HARRIS: Looking ahead, if I’m with you, I don’t think there will be much happiness either.

    TRUMP: I hurt you, and caused you pain.












  • too much ranting about cooler testing

    man CPU cooler reviews. I’m usually interested in two things:

    1. how is the performance of this cooler relative to others?
    2. how could I expect this cooler to perform on my system?

    I’ve read a lot of cooler test reports and at least in the older ones, I remember so often they could present useful comparative data but not absolute data. For instance, straight up not measuring the CPU power draw so that unless you have this exact CPU it wouldn’t tell you much about how the cooler would perform on your system.

    I mean look at this - how much power is “Idle”? and “load”? STOP TELLING ME WHAT THE VOLTAGE AND CLOCKSPEED IS I DON’T CARE. HOW MUCH POWER IS IT

    I remember I would have to dig up other reviews of the CPU where they report the power draw at different clock speeds so I could guess at how much power was being dissipated in the cooler tests.

    This review kind of has the same issue, though it tries to do better. I do appreciate the attempt at doing a standardized constant power testing, but the results are unrealistically low for core temps. The Hyper 212 absolutely does not hold 32.8C over ambient at 200W of real CPU heat dissipation (at least, unless the ambient temperature is like 50C. what is ambient? I don’t think they specified). This doesn’t seem like a good approximation of any modern CPU and is still only useful for a comparative test. Or maybe this is more of a Tcase estimate, which is much less useful than Tdie.



  • Yeah, definitely. The more I think about it though, the less important I think this is. I suppose there’s good reason that GPU brackets are popular and nobody bothers with a CPU heatsink bracket.

    I realized that just the CPU cooler mounting pressure already loads the motherboard like a beam with a point load. This certainly results in some bending stress already, so perhaps the additional stress from the weight of the cooler hanging off the board is really not significant.

    … I just lay the whole thing down on its side so I stop thinking about it.



  • I am all about comically large air coolers. Quiet, effective up to like 200W and zero leaks. Watercooling looks better though. Tubes.

    The one thing that I don’t like about air coolers is how every case positions the motherboard vertically, which means the heatsink (if giant like mine) applies a lot of torque on the motherboard. I have never had this cause a problem, it just does not sit well with me




  • Somehow I feel like the green on some green PCBs from the 80s and 90s look so much nicer than the standard green PCBs you get now, but I can’t put my finger on it. https://xdevs.com/doc/Fluke/8842A/img/acred.jpg

    There are makerspaces here, but they are still a bit far which sucks because they are cool. But with the time getting there and back plus the cost of admission, I feel like I’d have to be doing way more projects to make it worth. definitely one thing I regret about school is not using their makerspace enough. Also kinda the whole degree. hehehehhh

    Though I mostly work on electronics and I think the good thing about electronics, compared to machine shop stuff, is that you can really get a lot done with just a little lab. Precision gear still costs a lot, but it’s nothing compared to the cost of big mills and lathes and stuff. And it actually fits in the apartment
