Is it safe to use the vacuum mode with sensitive PC components (GPU, CPU, MOBO, etc)? or should I only use the blower mode for those?

You should always use the blower mode for all electronics. They should always be unplugged and not running when Metro Vac is used.

Turbine spins very fast, I hope people don't try to block it as it keeps things within operating temps. Duster already gets quite warm with extended use. Also as of note the fine tool attachment adapter has a 'blow hole'. I wanted to block it at first, but it regulates the pressure out of the tiny nozzle so it doesn't get overloaded. Don't try to block that either, it blows plenty strong without covering it up.

If you can't run it on recommended settings you should wait. Pulling the bare minimum will really run the experience, and most likely, your PC if you are not equipped with a good way to ventilate heat.

Also wanted to note that this is for incoming power problems only. You should also use surge protection at each electronic component, like an outlet or strip with surge protection. Internal surges can happen beyond your power source, example: Frig on same circuit, as a vacuum is turned on, can cause an internal surge on this circuit or one near it. This is a better setup for having all round protection. Most people I know have one or the other, better to have both.

I have the PC behind my monitor. I honestly can't tell you if we have 2 or 3. Anyone out there in Amazon land have quick access to the cover to count the fans? Sorry. So far no problems and cpu runs cool. I do take all precautions to always keep items away from top and side airvents.

I have run my computer (laptop with attached speakers and headset) on it 10-hours per day for the last year with A1 performance. It also is silent. The fan does not kick on unless a larger load is applied. The "only" issue I have had is I will get the red fault light every two or three months due to my connections to the deep cell batteries loosing good contact. I just clean the terminals, re-clip, and ready to go.

Sorry, I don't know. I've only had mine for several months and have had no problem, except that it functions on vacuum overkill.

Vacuum advance primarily, then will use mechanical secondarily. I'm presently using on a dual port air cooled.

I don't know what the manufacturer recommends. I would do what I do w/my similar items. I have a small blower for my keyboard, my refrigerator coils, my TV, etc. It blows out the dust. Then I vacuum up the bits of dust that float out of the item. Sorry I can't be more helpful.

Iaw Dell 760 specification, the mini tower has 115/230 VAC power supply. I don't see any selection switch (except a test button and LED) in/out. Most likely, it detects the input voltage automatically to set it themselves. My one works well for 115 VAC. The specification suggests "See safety information that shipped with your computer for important voltage setting information".

Long answer: I was lucky enough to have my USB ports on my desktop pc close to the PC's power supply fan outlet. So it actually blows a continuous stream of "coldish" air on the ASIC miner. So I don't use a separate miner. It's been running 24x7 for about a month without any issues. But it does get hot when running without a fan, and electronics generally don't like getting too hot. So I imagine the life time of the device will be shortened if it's running hot all the time. These devices are quite new and have probably never been CE approved or similar, so basically no one knows for sure. But I've yet to see any reports online about ASIC miners catching fire. That's a good thing. Also a cheap ebay or china USB fan is probably not CE approved either and not built to run 24x7 as is probably just as likely to burn :) Short answer: If you have any kind of circulation and make sure the two miners are not close to each other (causing heat to build up) I'd not be that conserned about a fan. There is a heat block on them. But if you dislike having hot things sticking out of your computer try to give them some kind of cooling.

Yes. the "O2 Hurricane" that I have is quite safe for dusting any devices or surfaces that I've used it on. I cannot attest to their claim of (220+ MPH), because to my touch the "O2 Hurricane" has a somewhat lower PSI output then a Standard can of Compressed air such as "Dust Off" ,However so far it works well. The only drawback for me is that the devise is very noisy when operating due to it's high speed compressor motor.

Absolutely not! It is a good idea to take the cover off one a year or so and blow the dust off but by removing the cover you inhibit the airflow over the cpu and mobo making the cooling fans useless. The case is what generates the wind flow. Keep it clean and covered and you will have no problems

There are two modes low and high selected by a switch on the card. If your hard core gaming, using CAD, bitcoin mining your going to need to select High mode which can be rather loud. If you just surf the internet and chat then Low mode will work which is very quiet. High Mode runs while card is "Hot" In General high performance causes these cards to run very hot so good air ventilation is a must.

This actually has to do a lot with the program you're using. I'm using BFG miner and I know that depending on the CPU you have, it may hog up some resources. I know on my PC that I cannot run them while say ... playing games, but for browsing, and excel tasks its perfectly fine. BUT I HIGHLY RECOMMEND you use a secondary PC dedicated to mining. These miners HAVE TO STAY COOL, so unless you use your work laptop in a 35 degree Fahrenheit environment, I do not suggest you simply plug it directly into your laptop. I have 5 of these running on a USB hub with a USB fan running over them. If you don't have a fan, they will fry. This actually has to do a lot with the program you're using.

Yes it can. However, would I recommend cleaning sensitive electronic equipment with a floor vacuum? No I would not. If you are using the unit only to clean the cpu and keyboard that is fine. However, if you are using it for any other use it will have an inherent level of dust that can and will harm sensitive equipment. Also, this unit may be cumbersome to use to get into the nooks and crannies as it is larger than those vacs designed to clean computers. I suppose the choice to use it this way is up to the individual, but I personally would not.

It blow hot air out away from the box. I saw no difference in temps however, and it was loud when new and even louder when it went bad. No matter what, dust will get stuck on it, and it will get progressively louder. I do not recommend it. I suggest some vented PCI slots if you want some additional cooling in that price point.
