There has to be a reason. When I pull mine apart to change the display board I'll check the temps on the SMPS. If the fan is indeed cooling off the supply I should  be able to see it.
Could it be that your supplies are going for another reason, are you sure it is the fan being off? I've been monitoring the fan all night with the instrument on and then off. I'm just not seeing any great variation in the temp, maybe a degree or two but several variables could be causing it.

I think Gerry's been running for awhile with his mod.

Hi

Once we started replacing fans, the supplies stopped dying.....

Replacing fans? Are you saying the fans went bad?

Hi

Nope, the dirt and the like got them really noisy. I suspect they were not moving as much air as they should have. We started pulling them wholesale and that did the trick.

Uncle Bob,
Did these counters have any of the oven options?

Hi

Nope, we run them all of of external standards in multiple plants. They were purchased over at least a 10 year span, so no, we didn't get a uniquely bad batch. It took us a while to figure things out. A lot of 53181's bit the dust "donating" their power supply to the 131's and 132's. Yes, hanging on to the rest of the chassis (for the DISPLAY) would have been a really good idea.

Good to know, I'll make sure to check temps on the SMPS when I pull it apart to change the display.

You should have kept the displays!

We never throw anything out.... Sometimes this can work to our disadvantage! ;D

Hi

We tend to do the same thing. When it gets to the point that you are renting space in multiple locations to keep "stuff" the finance boys start to get into the act. Eventually an edict comes down. Unfortunately I do the same thing here at home. The space runs $550 a month. That's about $100,000 over the last 15 years or so. Want to bet I could buy a lot brand new gear for $100K? Same logic applies at work except their rent was running about 10X mine.

Uncle Bob,
Let me put this into perspective, my wife Nancy calls it the Robsonian!

Hi

My wife is far less kind when referring to my collection of "fine stuff" ....

I think if my stuff got a name it'd become part of the family. So, no naming here. However, the Robsonian sounds like a nice place to visit.
I TEA.
