A couple of quick fan related questions

Hi all

Just built a new PC with a lian-li lancool one case, 2700X and Vega 64. I think I need to improve the airflow a bit as it only comes with a couple of fans, so I figured I'd add a 120mm to the front and a 140mm to the top of the case.

First issue is I've only got one more fan header on the motherboard, but I've notice I can get one of these cables to join two of them to one header. So I figured I'd move the 120mm fan from the back to the front so that they are both the same, and join those two to a single header with the splitter, then add a new 120mm to the back, and a new 140mm to the roof.

So the questions:

- Are these splitters okay to use? They do a 4 way splitter that also has a Molex connector, and it says you must use that if connecting more than one fan, but the two way splitter doesn't have a Molex connector, will it be safe to attach two fans without this?

- Any particular fans people recommend? Obviously after something fairly quiet but don't want to spend loads. I'd quite like the rear one to have white blades as the current one looks nice, especially as the light from the nearby LED on the motherboard reflects off it, or could be tempted to get an LED one. As far as the 140mm one goes I'm thinking black as its off centre on the top and I think I'd rather it be more discreet.
 
Noctua and Bequiet Have great low noise fans, however if you are after something that costs less then Alaska Apache fans look good also. Take a look at DBA levels (at 100%) Vs airflow and you can get an idea of how quiet a fan is going to be for the amount of airflow produced. Aim to have positive air pressure, more coming in than being drawn out.

The splitter cables are fine to use from my experience.

Thanks, I'll take a look over the weekend and will bear that advice in mind. Noctua actually seem to have some fairly reasonably priced fans in their redux range.
