What is the name of the connectors found on a Fan?

[#1]

I want to buy some of these connectors in their 4 pin and 2 pin variants but I don't know what they are called do you? Also I'll need a crimping tool as well but I suspect I can find that once I know what the name is. Anyone help with this?

Having searched for an image I see they are referred to as Molex Small but searching CPC for 'Molex Small Female 2 Pin' doesn't give me the above.

try this Mook  " molex KK "

For the connectors, search eBay for "111121574501", and make sure you tick the "Include Description" box.

@rongtw is correct they are Molex connectors, you can buy them from RS, unless you are going to be making loads up, you're probably not going to want to buy the crimp gun as they are £182 and £261 depending on which one you need.Probably cheaper to find pre made leads and tweak them to your needs.

A lot of PC supplies places sell splitter and extension cables that you could adjust to meet your needs.

e.g. https://www.amazon.co.uk/Akasa-AK-CBFA01-30-PWM-Extension-Cable/dp/B003VYB76I

For the crimp tool, search eBay for "120933035908", and make sure you tick the "Include Description" box.

Thanks for everything guys, got them, 2 x 10, 3 x 10 and 4 x 10, plus 100 sockets all in for 8.99 from CPC now that I know what they were, and a ratchet compression tool from amazon for 15 on prime. All this because I have OCD!
