Optiplex 745 Fan Noise and Part # ?

This question has suggested answer(s)

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.

    I think its

    Dell Optiplex 745 755 HDD Caddy and Fan UU520 HK120

    Dell Optiplex 745 USFF Hard Drive Caddy w Fan & Cable TY656 HK120

    Dell Optiplex 745 755 Hard Drive Blower Fan HK120 HK253

    I do not work for Dell. I too am a user.

  • 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.
