K, I fixed a ps3, ylod, works but the fan does not go higher or adjust for heat. So I said, Before it burns up. I'll add a 100k pointemeter to it. and try that. and that worked, but the 100k is soo sensitive, that pretty much its on full speed. (the fan). So I got a 250k coming, Im hoping this will allow me to actually have some adjustment range. Since the 100k, is too sensitive. Or will I see the same issue with the 250k ? this is a cecha01. 60gb . I'm glad I got it working after a few tries of fixing the ylod. not sure what if the sensor for the temp control built it, fried or ect. the fan comes on, but does not increase in speed. Any additional thoughts ? comments.
