The Neo Geo I picked up on Saturday came with a handful of relatively minor issues. Among them was a noisy power supply fan that quieted down after a few minutes of operation. Fine if it’s living in a basement arcade, not so much in an office, so it was one of the first things I wanted to fix. <\/p>\n

\nThe power supply in the Neo Geo (an MVS-6-25 oversize upright unit) is a Happ Controls Power Pro. It’s extremely easy to extricate, held in by four screws and hooked up to the rest of the machine but three modular connectors. Once you’ve got it out there’s a handful of standard computer case screws to remove and you’ve got it open.<\/p>\nngg_shortcode_1_placeholder\n

\nRoomy inside, and we can see that the fan used is the same style found in pretty much every desktop computer ever. <\/p>\nngg_shortcode_3_placeholder\n

\nThe spare I had on hand was a new Rosewill unit from Newegg, and it had an extra lead for speed monitoring. The one in the power supply had a 2 pin connector so I needed to splice on the old connector to the new fan for it to work. Couple minutes spent soldering and some heat shrink tubing and the operation was complete.<\/p>\n

\nEverything stitched back together. Overall a very simple repair, but it will make the machine way more pleasant to be around. As a bonus I found an original SNK mini marquee blanking plate and a few dollars worth of quarters under the power supply when I pulled it. Yay!<\/p>\n","protected":false},"excerpt":{"rendered":"
