Fan comes on when using Xee

[GoogleCodeExporter]

First of all, if you have any Haxies, InputManagers, SIMBL plugins or
similar operating system hacks installed, please remove them first, restart
the program, and make sure the bug is reproducible without them.

What steps will reproduce the problem?
1. Use Xee to look through photos for say 30 mins, move back/forward 
frequently, delete say 20 % etc.

What is the expected output? What do you see instead?
Expected: Nothing really.
What happens: Fan comes on, Checking cpu it seems ok, its putting on a bit of a 
load, say 10~20% max. Quitting Xee and the fan stops in about 10 sec. I would 
not expect an image viewing app to be so heavy as to need the fan coming on. Is 
this normal?

What version of the product are you using? On what operating system?
3.4 (35) on Mavericks on a 12-18 Month old Macbook Pro Retina 13
