The vents are actually quite clear. The last person to live in my unit did a shitty job of repainting, there's lots of bare grey metal which looks like dust in that photo. I like the idea of AC fans. It completely redirects my thinking. I found 4 small fans that wouldn't be overly loud (46dB all together), pump out a cumulative 800m3/h, not too expensive. While I thought about a switch as the easiest route, if I could have them turn on with the AC, that would be optimal. Perhaps a solenoid switch. Tap the solenoid switch into the AC to activate when the AC turns on, this solenoid closes the circuit to the fans which are hooked up to a separate circuit breaker. Anyone see any obvious flaws?

I need some assistance picking parts for a unique computer fan-based project. Though my ancient ceiling AC was recently overhauled, improving the airflow significantly, the construction around the vents themselves is causing weaker than desired airflow. I had the thought of using computer cooling fans mounted inside the vents to push the cool air out into the rooms which will turn on when the AC starts drawing power. In the rough-diagramed photo attached is my setup. The AC unit in the blue box blows cold air into the empty ceiling space of the green box. In addition to the vent shown, there is one half that size in the bedroom above the door on the right. The red squares are the not-to-scale indicators of where I'd place the fans for that vent. There'd be two in the bedroom and I'll be cutting a vent into the kitchen on the left with two fans. So, 8 fans in total that are relatively quite fans with high output. I have just enough knowledge to know this is possible while also recognizing I don't know the terms of the components I would need to bridge the power from the AC to the fans safely. Hence, I come to all of you to help guide me in the right direction to complete this project safely.

My i5-2400 has recently started to show it's age. My peaks and tweaks have reached the end of their limits. My current setup of what I"m looking to upgrade is a HP 8200 Elite running a i5-2400 processor with 4x2GB DDR3 and Windows 10.. I'm looking to upgrade to a i5-6600k and I need motherboard suggestions. Since new RAM is not in the budget, I need to stick with my DDR3. This PC is for gaming, browsing, and running Unreal Engine for developing the 16-bit style video game I'm working on. I've never been a graphics elitist, so high end graphics for gaming are not needed. Lower mid-range is fine for me. Also, having a weaker PC serves my needs for development perfectly because if it can run on my system, it will run on everything from next-gen down to budget mobile without issue. I don't want people complaining it doesn't run well for them and my response being, "Well it ran on my Binford 11,000 without a problem." I've included a photo of a non-modified 8200 Elite. Mine has modifications to the rear framework to allow space for a non-small form factor graphics card to fit. (Tin snips are fun and will be used again if needed:) Thanks for your time, thought, and responses! HP_Compaq_8200_Elite_PC_-_i5-2500_3.3_4GB_500GB_DVD-RW_Win7_Pro_COA_-_2UA1401HFK_5_grande.webp

I recently received a refurbished HP Compaq 8200 a word processing PC separate from my gaming system. I noticed it was extremely sluggish and quickly ascertained only one of two RAM sticks was recognized by the system. Recent vids led me to conclude a RAM stick came loose in shipping. Turned off system, waited two minutes, opened small form case, pivot up hard drive enclosure, reseat RAM, pivot hard drive enclosures back in place, system fails to boot up. Where I should get the Windows Loading screen, I get the message: "Non-System disk error or disk error replace and strike any key when ready" I check the BIOS and my hard drives are not being recognized. My initial thought was a cable came loose, so I reseated all cables relating to the hard drives. No dice. I am out of ideas as to other possible causes.
