Hi Guys, I’ve got a monster PC that I inherited from a friend a few years ago. He used it for gaming, I think, and so he installed a lot of fans on it. Altogether there are seven fans on the system. The trouble then being that there are only four fan headers on the motherboard (3 + 1 for the CPU). So three of the fans have to be connected to the main power supply, which means (I suppose?) that they are going round at full speed. Full speed is (a) very noisy, and (b) probably not really necessary for me, since I’m not a gamer.
So, as part of my late-lockdown PC awareness campaign, I just ordered a few of these fan splitter cables. Seven fans - so the idea is to leave the CPU fan on its own, and split the other six with two on each header, giving me proper control over each fan on the system. HOWEVER, I looked at a couple of YouTube videos about using splitter cables, and one of them was saying that you need to be careful not to fry your motherboard by overloading the headers. So I guess I would like to know how safe it will be to do this. Here’s the manual for my MB, GA-Z77P-D3, and on page 23 there’s some limited information about the voltage:
But of course because I “inherited” this machine I don’t have any idea about how much power the fans are taking. As far as I can see, they all look pretty much the same regulation size (120 mm?).
So the question is whether it’s safe to have two of each of these on each header??? Thanks very much
