It's been 10 years and I have upgraded my computer

[Soukuw]

Sabertooth 990fx -> Z390-A PRO (m2 slots, DDR4 and new features to learn about)
AMD 8370 -> i5-9600K
24GB DDR3 -> 32GB !!!DDR4!!! WOO
nvidia 970 -> nvidia 970

$200 for the CPU/Mobo/RAM from my brother. I think it's a pretty good price and on top of that he's taking Counter Strike crates as payment


This was the inside of my PSU I've never cleaned. Still works fine. It's a 650 watt

edit: Disclaimer I've read lots and lots of extreme warnings about opening up your PSU. Be extremely careful and don't go sticking your fingers on things. Cheap PSUs might not have a circuit to drain the capacitors or they might not drain fast enough. Touching these wrong can apparently kill you.

In hindsight I probably should have been more careful, I did pull a bit of dust out but should have exclusively used the vacuum (plastic tube) and canned air to get the stuff loose. This all could be some elaborate myth though, not educated enough to say.

I've been running the i5-9600K on my Minecraft server/living room media PC for a good six/seven years; it's single core performance carries it--solid CPU. I just upgraded my drive on it to NVMe, and there's almost no latency now.

Just don't go digging around with your fingers, apparently there's things in PSUs that can hold a charge and will forget your day up.

as long as you clean any dust filters and use some compressed air for the vent holes occasionally, you should be fine.

Also my house is ancient and was pretty gross. (Still is but slowly I clean) Lots of dust in every crack and what not. The computer has also been around cigs/weed/vapes and that usually does a number on them. The smoke gets in the fans and sticks to them and then the dust sticks to that. Whenever you see darker brown gunk on the fans it always seems like it's from smoke.

Guessing most PSUs don't usually get this gross.

I don't know anything about electricity but does anyone know what the thing/things you could test for with a multi meter that could change from cleaning a PSU? Does the dust raise resistance or lower it? Curious what the extra heat does.

Heat does increase resistance just as cooling decreases it, in fact get something cold enough and it becomes a superconductor, but the extra heat from dust probably doesn't significantly alter the resistance, but I've never tested.

Personally, I always remove dust filters because they plug up easily and can cause the system to overheat. I'd rather have a bit of dust on the PC components instead of impeding proper airflow through the case.
Also, be careful using compressed air because it can spray liquid refrigerant. It's typically not a problem since it evaporates quickly but could still damage smaller components if hit directly.
Use a regular air compressor or one of those handheld plug in kind if u have it - and don't forget to hold the fans in place whilst doing the air blasting, otherwise it could ruin the fan bearings.

yeah the biggest thing with dust in a PC is just impeding airflow, and with a significant amount of gunky dust like what was shown in the pic it's more like an insulator for the components, which definitely isn't good lol
