adding a fan on the back of BVM

[asasra]

Hi all

I've noticed in the back of some of my BVMs there appears to be a place where I could add a fan.
These things get pretty warm so I guess this will extend the lifetime of the components.

I'm attaching a picture from mine, it looks like they'd have to be mounted from the outside because there appears to be some circuitry on the inner side of the vent.

I wonder if people have a recommened way to achieve this, including how to power the fan.

thank you.

Have you ever put a fan near a CRT? You are very likely to introduce magnetic interference if mount a fan that close to the comverence rings.

Like a lot of electronics, these use convection (vents) for cooling. If you are overly concerned about a specific component, I suppose you could add a heat shield or thermal paste, but you would need to able to have it on a ground plane.

My advice would be to leave it alone.

This topic is briefly discussed in the Savon-Pat interview if I recall. He does recommend a fan on these old monitors as heat is the biggest enemy of their long term health. Always an exhaust, never an intake.

I have no idea how you would go about wiring that up. I emailed Pat about it and he said it was possible and he was willing to talk it through with me over the phone for my BVM D20. We ended up talking about other stuff and I forgot to bring it up. If you're serious then I'd recommend calling him. He is amazingly friendly and oddly willing to shoot the shit with internet strangers.

My idea was to wire up a fan with something like this:

I imagine there must be a clever way to find an internal power source

Edit: If you do get some info be sure and come back and share it with us. I've heard about mods like this, but I can't recall seeing anyone document their journey.

I have a Shibasoku monitor with no built-in fan, but a heatsink on the power supply MOSFETs that gets so hot that it raises the temperature of everything nearby. I rigged up my own externally-powered fan to blow on this heatsink, and it seems to make quite a difference. I'd especially recommend this kind of thing for a monitor being run in a high-ambient-temperature room.

Just buy a 12v 1 or 2 A transformer. Cut the wires near the plug and connect it directly to a splitter which will carry the current to 2 fans. One in extraction behind the monitor and the other in input above the internal transformer. Total expenditure around 40 euros.

this is the point during the interview where savon pat suggests putting in an exhaust fan

looks to me like it should be very straightorward to mount a fan on the spot I pointed to.
I hope someone can give well defined steps for us non electronic types to follow.
The thing is how to hook up power internally more than anything else I think.


By the way I'm in the process of rackmounting my BVMs for some nightmarish unknown reason.
You might be interested to know I'm planning to put one of these bad boys over the units that have vents on the top:
