AGA MKIIcr problems with glitches on screen only on WB ?

[som99]

Open the top half of the amiga then put any fan above the indivision aga and try again, I had serious heat issues when I installed the mk2 and to keep it cool enough and still as silent as possible I had to use one silent 40mm fan directly above Lisa and 4x 40mm fans at the grils in the top lid.

If I turn the fans off within 5 mins I get artefacts and if I start a whdload game it kicks me to wb within a minute with a obscure error message or guru.

So im one of the unkucky with heavy heat issues so try putting a fan there and keep the lid open and see if it helps.

update: installed a low profile heat sink on Lisa and fan inside the case first thing this morning and my 1200 has been running for 8 hours now with no problems at 1024x768 so problem appears to be solved :-)
I think I'll be using 800x600 as WB is alot more snappy with it on my system though 1024x768 is much faster if I go down to 16 colours. Also haven't tried Jen's tune program yet as all screens seem to be working fine without it so far.

Happy to hear that your problems are solved Just out of curiosity may I ask what revision your motherboard are?
