Hey everyone! I'm thinking about getting a dust blower to clean my PC since I feel it might be a better long-term solution than using those compressed air cans. I found a model like this one: https://www.amazon.com.be/-/en/Dusters-CompuCleaner-Xpert-Dust-Blower/dp/B01G1Z0RF0 . I just wanted to check if anyone knows if using this is completely safe for my PC. I've heard that static electricity can be a problem with vacuum cleaners, but I'm not sure if this applies to dust blowers too. Also, what's the best way to use it? Should I unplug the PC, turn off the PSU, and then start cleaning? Thanks a lot!

The main concern with vacuums is that they can generate static by sucking in dust, but a blower typically has fewer issues. It's better to keep it plugged in while cleaning to ground the system. Just remember, don't touch any components directly with the blower tip to avoid scratches or knocking anything loose—that's where most damage happens, not from static!
For over 20 years, I've been using a simple 2-gallon air compressor to blow out all my electronics, including PCs and TVs. I always make sure to keep the condensation out of the tank, and I've never had issues with dust or static damaging my gear.
I've cleaned out PCs many times and now I even use a mini leaf blower for a quick clean! It probably makes some static, but as long as you avoid touching components directly, you should be fine. Holding the fans to stop them from spinning isn’t a huge deal either, especially with modern setups.
Using a dust blower should be fine! Just a heads-up though, I wouldn't unplug the PSU since keeping it plugged in helps ground the system, reducing static risk. Just make sure to hold the fans so they don't spin while you're blowing dust out.
I was actually planning to use it outside so the dust doesn't spread everywhere in the room... I'll figure out a way.
Thanks for the detailed answer, I appreciate the tips!
