To Push-pull or not? Is turbulence an issue?

[Baldbloke]

I've done a little bit of googling on this but failed to find definitive answers.

Using Akasa venom with 1 * push fan at the moment. Will push/pull provide better cooling?

Or is push-pull fans advantage mostly negated by added turbulence? I'm assuming it would be impossible to synchronise both fans to eliminate turbulence. Would added turbulence create more noise? Should fans be a matched pair?

My Asus p8p67 has only 1 * 4 pin cpu fan header. If I were to try push-pull, how would I connect it to a single 4 pin cpu header? Should I just get a 2nd cpu fan with 3 pins and connect to the 3 pin header next to the existing 4 pin cpu header on the Asus p8p67? Thus using one 3 pin and 1 4 pin fan.

Thanks folks.

As the fan supplied with the venom is the akasa viper, you would need a second viper and one of theese cables for a push/pull setup.

With this adapter power is provided direct from the psu, both fans will run at the same speed therefore turbulence wont be a factor. A push/pull setup will drop temps, but it will vary from user to user.

Thanks for that. I see from the labels on the splitter cable only one is marked cpu fan. The other two are marked case fan. I imagine the Case fan label could be used as a cpu pull connector? Also, there are only 3 wires, that I can see, connected to the mobo header plug. Would it matter if it went on to 3 pin or 4 pin mobo header?


AceTK, Yes, quiet would be nice but I wouldn't want to spend too much cash on cooling unless I had a temperature problem. (I don't. Just interested in cheap, effective cooling. A compromise, really). I certainly don't want to go down the water cooling route. My pockets aren't that deep.


Thanks.

Thanks Setter, I'm going to give it a go.
