Heat fan too much stress?

My tub isn't getting enough heat as I would like but I'm still messing with it. My Question is if i put a heat fan next to it will it cause him stress from the noise. Its not extremely loud but loud enough.

If anyone uses a heat fan for extra heat or thinks its not a good idea please let me know. Or any tricks you guys use.
Thanks a lot =)

The noise wouldn't bother him, but it would likely totally kill your humidity...

I'm not quite sure what a heat fan is, but it shouldn't bother him. I wouldn't point the heater towards the tub, it will really heat up the tub and your fan won't adjust itself when it gets too hot in the tub. If you are going to use it to heat up your room, no problem. In the winter months I use an oil space heater to keep the temps up in the room so I can keep the cool sides of my tubs up to 80. It did kill the humidity in my large tubs so I had to do some tweaking.

i run a heater with a fan about 3 ft from my rack and my humidity is good and no stressing out the snakes...my heater is about 3 ft tall and about 9 inches wide...
