I have a number of Optiplex 745 Ultra Small Form Factor PC's.
It seems like the CPU fans are in the process of wearing down.
I have one OOS already.
Checked the parts list and ordered a new CPU fan 4R197.
It turns out the fan is 1/2 the original size.
Anyone know the right part number.
I have a pic of the 2 showing the difference.
The one on the left is the one shipped. Obviously too small.
What is the Part Number on the barcode on the fan
Ignore the CN-0 and the next numbers are the dell part number.

It would be "HK120-60362"
Interesting that I got the wrong part, the small one, from Dell.
Thanks for your help. I'm weeding through some of the searches for HK120 to try and find a couple fairly reasonable. Some I've found want as much for the lousy fan with bracker as buying a used 745 PC.
