IR on MCC Cooling Fan jungerer 4/19/2012
We just started doing IR inhouse. Our prior test was done by an outside contractor. Here is their last images they took of one of our MCC cooling fans. http://s1255.photobucket.com/albums/hh621/usgnkcir/?action=view&current=SuctionDrumMCCCoolingfan2_27_12.jpg" target="_blank">http://i1255.photobucket.com/albums/hh621/usgnkcir/SuctionDrumMCCCoolingfan2_27_12.jpg" border="0" alt="Photobucket">

They suggested replacing this fan. It is measuring 98F immediately after turning off. Ambient was close to 80F.

This doesn't seem bad to me but I'm still pretty wet behind the ears when it comes to IR. It's a NULINE #02557734 fan. I can't find much info on it. It doesn't come with a data sheet. The most useful info I can find concerning temp is that its max ambient temp is 176F.

I went recently took a pic of the same fan and got a max temp of 115F while it was running. http://s1255.photobucket.com/albums/hh621/usgnkcir/?action=view&current=IR_0174.jpg" target="_blank">http://i1255.photobucket.com/albums/hh621/usgnkcir/IR_0174.jpg" border="0" alt="Photobucket">

What are your thoughts on this? Would you recommend changing this out?

114F on a small fan is not a problem. I see the dirt and dust being a problem over time but at those temps you are fine.
