I think thats whats preventing many people from doing surgery on there
tubes. Ive been looking for a differnt type of foam for to mount the
fan on. Im sure Ill run across it sooner or later.

Another thing you might like tyring is going to radio shack they have
a closeout going for indoor/outdoor car thermometers. There small
black and have the indaglo redout that you can trigger by touch. It
also has memory for high and low temp.. Ive affixed the sensor the the
back of my mirrror. The readout is affixed via velco to the tube. I
can readily see several degrees difference between the mirror and
outside air esp if temp is falling.

The rheostat that Del mentioned is a great idea esp if your scope
suffers from the shakes at high speed.

Best of luck

Rich,

The best vibration isolation material I found for my fan mounting was the
xorbathane insert out of my running shoe. That stuf worked like a champ. I
put double sided foam tape on either side of it to stick the fan to the back
of my mirror cell.
