Strange A1200 behaviour... caused by overheating?

[JaXanim]

Hi Steve,

An 030/50 can most definitely cause a hangup through overheating.

I had a Microbotics card with this CPU and when I fitted into my standard A1200 desktop, it stalled all the time when running CPU intensive stuff like Imagine (3D rendering - you can't get more intensive than that).

I tried a heatsink/fan and tht workrd OK (if you can stand the racket!) Eventually, I just jacked up the keyboard using rubber door stops as legs and removed the trapdoor to let air into the slot area. That worked a treet!

Cheers,

Definitely sounds like something is overheating.. but can be both cpu and powersupply...

Of course, using an expanded A1200 on a carpet can overheat it, but I think users are too quick to point the finger at overheating. Software is by far the best way to crash an A1200...

Then why would it help to turn it off for a few minutes?? This can only be some kind of hardware prob, either power, overheat or some defect..

I have a 030 (with fpu) card in my a1200, but I -have- to remove the trapdoor lid to prevent random crashes  due to heat.

Also I replaced my original PSU with an A500 one..

Way back when my A1200 was untowered and I was using a Blizzard1230 I had to remove the trapdoor-cover and put spacers under the 1200 to get some air under it. If I didnt - it crashed after a while. I suspect that some A1200s - like mine, are more sensitive to heat because a friend of mine later bought that card from me and used it in his A1200 without need for removing trapdoor-cover or putting spacers under the A1200. That made me realize that my A1200 isnt exactly the best one manufactured and that the Blizzard1230 was very stable indeed.
