My Psu only has 4 molex connectors and i want to split each of them for more fans, Is this safe?

I generally stray from adapters. 

 

Had one person on here that used an adapter/splitter and it melted.

 

Cheers.

A few more than one...

They all either melted, caused smoke, had unreliable power delivery, or killed components.

 

That said, I've got a molex powered fan that doesn't have any issues despite being from the XP era. Why don't you just get a normal fan splitter though?

The fans don't had dual sided plugs so you can daisy chain them ?

Typically, no.

 

What PSU is it?  Generally, the wire gauge of the PSU is selected by the manufacturer based on the number of connectors and therefore how much current is expected to be delivered.  If you use splitters, you potentially double that expectation.

It's similar to using a power strip, it is safe as long as the combined current draw (measured in A) of all of the devices isn't greater than the amount of current a single outlet can handle.

Let's say the cables inside a outlet can handle 20A of current going through them, if I get a strip and plug 2 15A heaters (30A) I'd burn the outlet or start a small fire

You can apply the same concept to a PSU, don't overload it and everything will be fine.

Well... the good news is fans tend to draw relatively low power, so you should be fine.  Just don't go nuts.  ;)
