Llama, if it wasn't locking up in the first place, I'd never of checked the temperature

I have never had a heat issue before but think this must be one now. Maybe the heatsink isn't seated as well or maybe the two sata drives(raid), 4 ide drives & two optical drives have finally choked any kind of circulation out of the box...
I cut a hole up top/side and have a 90mm fan blowing out. So with the other fan blowing out in the case and the ps fan - I have 3 out going + one of those slot fans that sit where the pci cards go - it blows out too.
In front/bottom I have two 80mm fans sucking air in + two of the ide's are removeable so they have fans sucking air in too ...
even with all of that, the temps climb into the low to mid 50's and will lock up when I try to play AH, tiger woods or IL FB with the door closed..
is SpeedFan accurate with their temp indicators? It shows a red flame whenever my cpu temp gets above 50c
