HHELLPP! I have a Z-217 board in an OLD H-110 that runs incredibly hot.
As the room temp reaches >70 degrees, I begin to lose the hard disk.
The hot spot(s) appears to be the three 2901 chips on the right side.
Can these be replaced with CMOS chips and run cooler?  I have seen a 
lot of commentary about reducing the noise from the fan - how do you 
increase the cooling capacity?  I have a desk fan that blows into the
tiny vents on that side of the box.  Beyond 85 degrees, even this isn't
going to work.  The only other cards in the cage are the Z-207 board and
an old rev UCI RAM board with 512K on it.  
While I'm on the subject, what drives can I just "plug and go" on this
controller?  I have a Miniscribe 12 MB drive that I spend half my time
deleting from and half the rest compressing stuff.
