Cab Cooling
Lilwolf:
Sorry I didn't get back to the thread sooner.
BTW, most of my problems started when I put my bezel on my monitor. I moved my monitor back about 8 months ago and never put the bezel back on. So I believe this is a big part of the problem. Its not home made, but I believe the problem is air flow in the entire cab, not just the case. I've checked all the fans and put new thermal paste to make sure that the cpu fans are optimal. But case fans will only do so much if the intake is hot.
I ended up moving my computer on the outside again to do some testing and get it up and working. Then I haven't had time to do anything since. I want to make sure its really overheat problems instead of the computer itself is dying. It is an old PC (2+ years of daily use) so there are chances parts are starting to go. Works fine until I get into mame... and 20 seconds later full lock... So its sounding like overheat problems :(
Anyway thanks for all the input.

If you buy a 120mm 12 volt fan and run it at 7 volts you still get pretty decent airflow and it is nearly silent. You can get the 7 volts from your pc powersupply by hooking up to the 12v and 5v lines on the standard 4pin power plug.
I have two blowing directly over the motherboard (not in a case) letting the air out the vents at the top of the cab.

I didn't know you can do that.
just plug the 12v on one side and the 5v on the other instead of a ground. That will give a net of 7v. I didn't realize it was that easy.
Is it safe?

Warning note!
Some fans (not many, but particularly the larger/faster ones) will require 8 to 8.5 volts to actually start spinning. Once spinning, they can operate on as low as 5V without any dramas, but on rare occasion the 7V trick will not be enough to start these units spinning from stand-still.
Make sure you do plenty of testing with your fans if you are going to use the 7V trick. And at worst, you may need to chuck a 20c resister in there to slow the fan speed down a little. Not a terribly expensive mod at all, really.
TimmyB:
You can also get a fan controller that goes between the power source and the fan.
