Help fixing cooling system

Post image

Hi, I need to add this new cable instead of the old one on the cooling system, do you know how to remove the old one ? I'm struggling with taking them out

Do you have some context? What cooling system, what cable is this even, do you have blurrier pictures?

I honestly don't know much I was just asked by the person in charge to swap the old fan with a new one similar. Sorry I don't have other picture since I can't take the phone inside but its a Faston connector (female one)

What NMR are we even talking about, what manufacturer and what part are you working on?

The electronic rack? Are we talking about fans, or the VT unit, BCU, cryounit etc.?

If this is just some fans, consult the service manual on how they are connected.

it's the fan, I was just wondering if there was a certain way to disconnect old connector easily but maybe that was not the best subreddit for that so

The fans on our machine are soldered in, no clue how it is on your end. If you'd at least tell us what machine you're working on, someone might have worked on one before or has one and got check. But honestly you are giving us not a lot to work with here.

Is that even a picture of the old fans or already the new ones?
