MY 'new' GORF wont play for a more than a few minutes without crashing - garbled graphics, weird noises etc. After going through all the power related stuff i managed to fix it by rigging up a pc fan on top of the cage, blowing air in, it now plays fine.

Reading tuff here i can see that GORF does have heat issues, particularly in relation to U3 and U15, neither of which have heatsinks on my board.

For the sake of being careful i intend to keep the an system going anyway, but would heatsinks make a big difference, and if so, anyone know where to get any suitable ones?
 
Midway started adding heatsinks to some of the customs on the cpu board mid-production so some have them and some dont. They used a vertical mount TO-220 heatsink. They bent the fins straight on one side so it would not hit the pcb or other components.
I will see if I can find an example of the correct type. I think channelmanic has some nice 40 pin glue on heatsinks in his store that would work. They are actually better than what midway used.

I forgot to mention that if you go with any heatsink other than the original style you may have to put the cpu board in the front of the cage. Although I think that extruded finned heatsink channelmanic sells should clear. Its still a good idea to move it to the front of the rack so it gets the most cooling.

Im pretty newbie to this stuff, how would i go about doing that, bearing in mind the connectors at the bottom, i guess they would have to all be rewired?

At the moment i am checking the heatsinks out but although they look suitable and are very cheap, postage to the UK is over $16 which although not a deal breaker i would like to avoid!
 
well, having suggested this to someone else who then tested it with his boards i am surprised and pleased to report back that, yes, you can switch the boards round in a Gorf!

I have fitted a pc fan blowing air in and everything is as cool as so cheers for the good advice - i am still going to fit some heatsinks as you can never be too cool!
