USB instead of microSD for the operating system causing overheating

dankcushions

The experiment is simple, if you don't want to try running the operating system and games from the USB card to see what the difference is with both the operating system and games from the USB, then don't. But I'm not writing an entire text book about operating systems on a forum, if you want that than I recommend ' Operating Systems Internals and Design Principles 6th edition, by William Stallings' . And I'm saying that because if you don't put the time in to learn a subject, then parts of an explanation are just going to be misunderstood, forgotten, and the whole point is missed in the end. I'm currently taking 6 classes, and about to do homework

i'm a computer science BSc (hons) graduate. good luck with your homework..

Has anyone looked into the potential benefits of ball bearings?

@dankcushions Yeah? Hons? That's cool. The picture of the linux application along with your response of the game being in ram made no sense as a response to what I said in the quote. I'm not saying that you are lying, but I have a very strong suspicion that you are. I could sort of understand if you typed that and missed something I said, and did not include that quote. But the quote with what you said tells me that you have absolutely no idea what I was saying, which should be very easy if you remembered your Operating Systems class, along with about 5 other classes that are in the BS curriculum and all involve basic things about processes, memory management, page sizes, and process sizes. Considering that you were in no way trying to help with the problem of over heating due to my choice in the secondary storage device, and instead trying to badly argue a point that you never made other than "I'm barking up the wrong tree"; I think you like pretending to know things that you do not. I think that you like pretending to know more than people that you didn't know before hand actually know what is going on. I do not think you have a BS in computer science (with hons), but I do think you're full of BS about computer science.

So good luck feeling like you're some one that you're not. Its not like you can't actually learn what you're pretending to know. This is what happens when you decide to call people out on stuff that you're the faker about.

@NastyButtler322 i'm not about to get my degree certificate from the attic just to win an argument online (although i'm slightly tempted now!). you'll find you encounter some resistance if you make bold claims about n64 tweaks you've made, especially without any supporting evidence (the plugins can show fps, and linux can measure realtime IO in a variety of ways) or details about your testing process. make a wiki page about it, even. isn't that part of the fun?

i absolutely encourage experimentation and theories, but with n64 emulation the bottlenecks are demonstrable and they're not anything to do with the storage device. my vmstat output literally proves that. look into what bi, bo and wa indicate.

also, this isn't the place for name-calling and bad attitudes, but i don't want to put you off experimenting. running everything directly from USB should provide several benefits in retropie. i encourage you, or anyone, to think of some good ways to benchmark it.

@NastyButtler322 I'm guessing running n64 must reach the temps near its throttling limit and the extra heat caused by a usb stick might just put it over. Those little heatsinks do little to prevent overheating. USB sticks do generate heat, some brands producing more heat than others. The case can also add to the heat. Tried a case that acts like a heatsink?

How about you provide before and after temps to actually see what's going on and not just assuming what the cause of the problem is.

@dankcushion you already won. You've got BS hons.

Seems like the problem solved when I lowered the vram in emulation station to 90MB. But I haven't tested it much since then. It was doing it with every system that I tried to use shaders on. The N64 game play was running great, and did not cause over heating since I did not bother trying to use shaders for that system. I just mentioned that N64 plays well this way to give a reason to people so that they may want to try it and possibly have more help solving the problem, but it is solved well enough for me now.

Any cases you would recommend that act like a heatsink?

Also, do you know if there are any ammonia, hydrogen, and water filled heat sinks?

@NastyButtler322 apologies, no. I don't have a pi3. I'm using a pi2. If I do get a pi3 in the future I will consider cutting one up like this guy:

@NastyButtler322 I've seen someone in these forums mention the flirc case for heat dissipation. The top portion of the case is aluminum and it has a small area sitting over the processor. This essentially turns your case into a heatsink with a large area to dissipate heat from.

@NastyButtler322 Speaking of water cooling, I like how this costs 4-5 times as much as the Pi itself:
