it looks like an 80 but why not measure it to be sure?

its hard to tell without scale. you should just use a ruler or tape measure to check it.

Nidec UltraFlo V80E12BHA5-57
Dimensions: 80x80x38 MM
Voltage: DC 12V
Operating Voltage: DC 7 ~ 13.8V
Current: 0.6A

That's an 80mm server fan, 38mm deep. 7000rpm and 54db? Ouch. 60cfm is quite a lot of air movement for an 80mm, but that thing isn't designed to move a LOT of air, its designed to MOVE a lot of air. High restriction applications.

it was 90mm in tape measure

Probably 92mm which is just one standard.
Also measure the depth. Possibly, it is 25mm, but from the looks of it, I think 38mm is more likely.
Also, look at the fan connector. It looks like a 3 pin analog connector, but it could possibly be a 4 pin pwm connector.
Regardless, here is one site with a large variety of fans available:

it was 38mm depth and 4 pin connector, does depth matters?

Depth may or may not matter.
A 25mm depth will not move as much air as 38mm, other things being equal.
If max airflow is important, stick with 38mm.

Possibly, the mounting location may have some restrictions, but using a slimmer 25mm unit is likely to do fine if you want that.

What is this fan used for?
If it is a case fan, then any 92mm fan is likely to work.
If it is a cooler fan that needs to be installed in some sort of a frame, then better to match it exactly.

I bought a pc fan with small depth than my 38mm old pc fan has,
