I'm Messer's biggest fan
I’m really trying to be a better person this year
@@DavidWallz Me too man, we both got this. I believe you can do it, whatever your goals may be just remember that you can do anything you set your mind to. Be kind to yourself :)
No, IM Messer’s biggest fan! jk
Thank You for this
Thank you
THANKS MAN
I've seen thermal pads on ssd's?
Whenever our computers SSD dies, i can see that the thermal pad leaks onto the SSD?
Some of this is counterintuitive to me at 5:18. I know this is supposed to be following the exam guidelines, but it's confusing to say that thermal paste can be reused, but thermal pads should be replaced every time. I hope the questions on the exam are very specific with this one. A lot of people tend to reuse thermal pads as they don't degrade nearly as fast if not at all. However, if it's specifically stated in the exam that they are referring to short term replacements or same day cooler replacements, then it would make sense for thermal paste, but still wouldn't make sense for thermal pads to me. Any thoughts on this?
I believe thermal pads are supposed to outlast thermal paste by a long shot ?
I actually sell this stuff at my current job, IMHO you should replace the paste every time you remove the heatsink. Regarding the pad, it depends really. Regarding the thermal performance it should be fine to leave the pad on, if there is some sort of glue coating you should replace it tho
@@Kontaras987thank you
I always clean and replace the thermal paste.
Do you have recommendations for ESD straps and mats? Also would you recommend getting a screw driver set from amazon or something?
imo its not necessary just a pre caution. if you build daily then yes, but building for personal i wouldnt waste money on it. and checkout ifixit kits
Maybe a screw driver set if you want, it will come in handy not just for building pcs. Other stuff is not necessary.
Electrical engineer here. The right ESD mat can be chosen based on your application. is it going on the desk or floor? Will you be soldering on the mat? For a bench-top mat where you will just be working on computers and not soldering, a general purpose one will work. Finding one that has a connection for an ESD wrist-strap is preferred. And of course, make sure the mat is properly grounded, you can't just put it on the bench and start working. Grounding your mat to the center screw of an electrical outlet is the way to go.
Also, be sure that your flooring is not carpet, as this will undermine your efforts to avoid ESD. While others are technically correct that ESD precautions are not necessary, you don't want to fry your expensive CPU or other components. An ESD event is often imperceptible at the time or after-the-fact, meaning that troubleshooting can be absolutely maddening. Furthermore, even IF you discover you zapped a chip, you still can't repair it, so you'll need a new chip (or new piece of hardware if the chip isn't replaceable).
Yes, get a basic screwdriver set. Metal tweezers will help too.
