Fan Controller advice

[Gommsta]

Hi, recently purchased 4 YS Tech 80mm fans. I'm very happy with their performance (lowered temps 4 degrees all round compared to my old generic fans), however they're bloody noisy.

I'm looking for a fan controller to try and find a happy performance/noise medium. Problem is that 2 of the fans are 4pin molex and the other 2 are 3 pin mobo connection type.

Are there any fan controllers that would accommodate this? Looks are unimportant as it'd be hidden behind my case door anyway.

Cheers n beers

The 7V thing looks very interesting. Do you know what effect it will have on the fan CFMs? Is it proportionally less? i.e. 7/12s of rated CFM?

I think a dedicated fan controller might be better along with those wire adapter things Bri mentioned. Do OCUK do them?

Is cheap and cheerful ok with regards these controllers? Don't have to spend 40 quid do i? lol

Cheers
