Hi, Gerald --
Hi all,
I felt the rear if my Spectrum Analyser 492BP. I can not touch the
metal strip just above the plastic cover it's that hot. So I got out
my Fluke IR Thermometer and the surface read 56 Degrees C, wow.
I have discussed this with other people before, however it is now
summer down here and not being able to touch the rear in a hotter
climate is of real concern.
I just tried waving an IR thermometer around the back of my 494AP
after about two hours of operation, and the peak temperature I saw was
58C. Ambient temperature was approx. 27C in the room at the time.
I know you don't believe me, but that temperature level is fine. Quit
messing with it and have fun using it. :-)
Seriously: it is easy to do more harm than good by rigging up
additional fans or using a non-original replacement fan in these
analyzers. If you are not 100% confident in what you're doing, I'd
recommend leaving the hardware as-is. There is no problem to be
solved here.
