I found a spider made a home!

I couldn't snap a picture of it, my 10 year old daughter thought it was awesome and she took it upon herself to remove it in a timely fashion so she could release it outside. Sneaky little arachnids they are. Best way I can describe it is it looked like a small orb weaver type spider, about the size of a pea and was brownish looking.

I decided to open my case, which I hadn't done in about a year, to investigate a rattling sound (like a wire hitting a fan) and to my surprise in the I found a pretty sophisticated web, a spider and a couple of small insects it had captured. I'm not really sure how it or the insects got inside the case since there are no openings and every vent/hole has a filter covering it, but clearly they all found a way in. The picture below (old picture, but current tower) the area circled in red is where the web was positioned - between the fans, in all the open space.

I did have a small wire that was getting hit by a fan, so I got that out of the way and the rattling sound is now gone. I also took time to clean everything out.

I still find it odd that my daughter can scream bloody murder if a fly buzzes her or if she sees one in the distance and can't tell if it's a fly or a bee....but spiders, she picks them up in her hands and puts them outside.

Kids are funny that way.

Perhaps it crawled in through one of the holes above the expansion card slots. Or through the PSU.

No! Don't do that. Bug spray is full of all sorts of chemicals. You don't want that possibly corroding components, or coating components and attracting dust.

if you really wanted to, you could leave poisonous bait in some corner of the case, if any creature entered there , it would kill it, like you do in the kitchen with german roaches

I have seen folks use the oddest things ... carburator cleaner, bug spray even air cans held upside down so the fluid comes out. The later can break solder connections and even embedded circuit traces. Other than electronics cleaners and 90+% isoprophyl alcohol, all ese should be kept away from PC components.

I have only seen insect infestation being a problem with servers in rarely access "server closets" or with computers stuck in storage for extended periods. There's really nothing attractive for most bugs inside a computer for there to be a need for poisons or sprays.

If that bad, I recommend the house be treated - or at least set off a bunch of bug-bombs (with the computers turned off).

Easiest way I ever kept my PC clean was open case 24/7 and using a mattress pump to blow inside once every few weeks. The pointy thing is great for cleaning between the fins of your gpu/cpu heatsink,it's much more powerful and directional than canned air.

Never thought of a mattress pump but have seen a bike tire pump (with that "pointy thing" nozzle) work. Canned dusting gas works in a pinch but not for big jobs.

The best solution is to lug the computer outside and use an air compressor with a suitable inline moisture and particulate filter. NEVER EVER use an air compressor on electronics (or birthday cakes or young faces) without such a filter.

Also, resist the urge to see how fast you can make a fan spin - you can easily exceed design limits and damage (at least increase wear on) the bearings. I use wooden glue/Popsicle sticks to hold the blades stationary when blasting.

BTW, those cans of compressed dusting gas do not contain "air". It is typically hazardous difluoroethane (or similar gaseous chemical compound) typically used as refrigerants and these gases are extremely hazardous if inhaled. In extreme cases, they can damage the central nervous system, or even be fatal. So use in a well ventilated area or better yet, outside. Note in some jurisdictions, these are controlled substances and sold in a controlled manner, similar to cans of spray paint to [hopefully] dissuade “huffing”.

I once had a PC come in for repair, opened the case and jumped back when an army of cockroaches scurried out.
I actually had to put the case in the street and shake it all about to make sure they'd all left. Really made my skin crawl.

I use reusable can with air compressor, best way i have found to do it properly.

I use a Metro Datavac ED500 and blast it out every 2-4 weeks. My computer is dust free and I don't run any filters. Filter free operation keeps the machine running cooler. ED500 keeps it dust free. One of the best tech related purchases I have made. Great for keyboards, monitors, and plenty of non tech items too.

See 7 mins 28 seconds in on this video (not mine) to see it in action:

I don't bother with the attachment shown, I just use the black cone on the end no brush or hose and it shoots a torrent of air.

Ive been eyeing up one of these for a while. though the problem i have is my PC weighs a tonne and i gotta carry it down 2 flights of stairs before i can even get it out in the garden. The 760T chassis is strong but it cant maintain the same level of rigidity as a fractal define case due to the sidepanel being made up of acrylic or plexiglass.

I could always pull the hard drives and expansion cards out before I move it though. That will probably save a few kilos

I would kill it with fire. Or better - nuke it ftom the orbit. That's the only way to be sure. My arachnofobia fully supports that course of action. Fucking spiders.

Don't worry about taking it outside just have a vacuum cleaner and suck the dust up on your floor or whatever afterwords. If you dust it frequently it doesn't release that much dust anyway. Highly recommend this device it makes my machine run cooler because less dust, no air filters, and it looks better too. It is also kind of satisfying to use.

Well it's a empty can with a tyre valve, so you connect the air compressor to this valve and you use the can like a infinite air sprayer.
Thanks for clarifying.
My computer is dust free and I don't run any filters. Filter free operation keeps the machine running cooler.
Running without filters is fine, if you regularly inspect and clean as necessary. And yes, even the best filters restrict the air flow a little bit. But that is still MUCH BETTER than having a layer of heat trapping dust directly blanketing the heat sensitive components.

I sure don't like tearing down my computers to lug them outside and down to the garage level (where the compressor is) either. So having removable, washable filters on all my computers means I have to lug them outside much less often. So I would much rather go for better (or even more) fans than have a case without filters.

Buying a quality case from the start makes a huge difference with better (quieter and higher CFM) fans and better filter design.

Of course much depends on your environment in the first place. Old houses shed more dust. Arizona deserts have more dust in the air than other regions. Temperate climates might mean open windows. Pets in the house create much more dust (considering a major component of dust is dander, the microscopic critters that eat that dander, and the "stuff" those critters excrete! :eek:). More people in the house means open more doors letting more dust in (and more human dander and those dander eating critters again). And more kids (and pets) running around stir up more dust.

I am not a fan of using a vacuum cleaner, unless specifically designed for electronics (like the Metro Vacuum DataVac/3 ESD Anti-Static Vacuum/Blower with Hepa Filter). The problem with traditional vacuums is there is the significant potential for destruction from ESD. As the dust and air particles zoom past and crash into the nozzle end (especially with plastic nozzles) extremely high potentials of static electricity can build up in the nozzle. And when the nozzle comes in to close proximity to ESD sensitive devices, such as the CPU, GPU, memory modules and other high density integrated circuits (ICs or "chips”), that static can easily be discharged from the nozzle tip through the device, totally destroying it - often without the user even knowing a discharge occurred.

For those reasons, vacuuming ESD sensitive electronics is never preferred unless again, the vacuum is specifically designed with anti-static features. Taking the computer outside is always better. If it is pouring down rain, and taking it outside is not practical, you can use a vacuum, but EXTRA care must be taken.
  • Unplug the computer from the wall.
  • Touch bare metal of the case interior to discharge any static in your body, and most importantly, to put you and the computer "at the same potential".
  • Wrap your hand around the nozzle end and extend a pointed finger out past the nozzle.
  • Plant extended finger on to bare metal of the case interior when reaching in with the nozzle to prevent the discharge and build-up of static.
  • Use a clean, soft, natural bristle (not synthetic) dusting or paint brush to gently persuade the dust towards the nozzle.
  • Keep that finger planted, and immediately replant it onto bare metal when re-positioning the nozzle.
  • Better yet, wait for it to stop raining, then use a properly filtered air compressor or cans of dusting gas.

Ive been eyeing up one of these for a while
Remember, the Metro Datavac ED500 is a blower only, not a vacuum. So unless you want to blow all that dust (and allergens) up into the air of your computer room where it can be drawn back into the computer case by the case fans (and into your sinuses too! :fear:), you still need to lug the computers outside.
I could always pull the hard drives and expansion cards out before I move it though.
Except, especially with the PCIe slots, inserting and pulling cards too many times will weaken the tension of the contacts in the slots. That could eventually affect continuity, not to mention start to allow dirt to get into the contacts. I just lug them all outside with everything still installed and connected. Then with your next computer, go all SSDs to save weight. ;)
The 760T chassis is strong but it cant maintain the same level of rigidity as a fractal define case due to the sidepanel being made up of acrylic or plexiglass.
Nah! That's not a problem. Corsair makes good cases - especially with their upper tier cases. Just keep the side panel in place when lugging it about so it does not flex and put extra stress on the motherboard mounting points.

But that case has filters anyway and while dust will still get in through other cracks and holes, you should not have to break it down to lug outside too often. FTR, that's just another reason to have CoreTemp or another HW monitor sitting in the System Tray. When you start to notice temps regularly sitting higher than normal, it is probably time to clean the filters! ;)

I never use a vacuum cleaner due to the static charge they give off.
A light brush and/or compressed air in a can used carefully.

Fine makeup brush and air compressor with regulated air @ 4 bars plus hands/fingers will solve the spider problem. It will also nicely clean the case. Just squash those long-legged ones with your hand or fingers when possible and wipe their remains. That's how I do it, except I don't have them in the case but rather in the corners and behind the furniture. :D

Thanks for clarifying.
Running without filters is fine, if you regularly inspect and clean as necessary. And yes, even the best filters restrict the air flow a little bit. But that is still MUCH BETTER than having a layer of heat trapping dust directly blanketing the heat sensitive components.
No what is better is just not having any dust AND not having any filters. Filters block a lot of airflow and are very overrated at dust prevention, it often seemed like I had the same amount of dust regardless of filter or no filter. But what does cut down on dust is blowing the case out on a regular schedule every 2 to 4 weeks. Once the filter is clogged you might as well not have a fan at all. Filters increase case temperatures and increase noise. They greatly reduce fan efficiency. It takes under a minute to turn on the data vac and blow the whole case out about once a month. Most of the time consumed is unscrewing the thumb screws on the case side panel. There is rarely a visible spec of dust at any given time I open the case, even before I use the duster. And if you run a vacuum in the room after you dust the case out with the ED500, the reintroduced room dust is taken care of. The DataVac ED500 costs about the same as buying filters and buying duster cans but it can be used as much as you want. There is no downside besides the $50 price. If you are blowing so much dust out that you are choking on it and it makes a giant maelstrom of detritus that gets sucked back into the case, then you have some serious dust issues and probably aren't cleaning machine frequently enough (once a month is a good interval). When I dust it out theres usually a very tiny bit of visible dust that comes out but it is rather insignificant. On this cleaning interval, there is not enough time for dust to even build up. I vacuum the floors after. Buying the ED500 was one of the best computer purchases I have ever made.

I found a spider made a home!

I couldn't snap a picture of it, my 10 year old daughter thought it was awesome and she took it upon herself to remove it in a timely fashion so she could release it outside. Sneaky little arachnids they are. Best way I can describe it is it looked like a small orb weaver type spider, about the size of a pea and was brownish looking.

I decided to open my case, which I hadn't done in about a year, to investigate a rattling sound (like a wire hitting a fan) and to my surprise in the I found a pretty sophisticated web, a spider and a couple of small insects it had captured. I'm not really sure how it or the insects got inside the case since there are no openings and every vent/hole has a filter covering it, but clearly they all found a way in. The picture below (old picture, but current tower) the area circled in red is where the web was positioned - between the fans, in all the open space.

I did have a small wire that was getting hit by a fan, so I got that out of the way and the rattling sound is now gone. I also took time to clean everything out.

I still find it odd that my daughter can scream bloody murder if a fly buzzes her or if she sees one in the distance and can't tell if it's a fly or a bee....but spiders, she picks them up in her hands and puts them outside.
If that was the kind of spider it sounds like it should have been stomped, made flat or something because that description is alot like a brown recluse would be.
You don't want to get bit by one of those and she needs to know some spiders can and will do harm if given the chance.
