Delta EFB1212VH

post #1 of 3
Thread Starter 

Replaced the stock fan on my Cooler Master V8 and the new Delta runs at full blast all the time. It has a blue wire on a three pin connector that indicates to the MB what speed the fan is running at. Well, duh, i can HEAR how fast it is running. Don't see the point in the mobo knowing the fan speed unless it can actually DO something with that info.

I am looking at two options.

1> somehow patch the fan into the mobo's 4pin so that it can regulate the speed according to CPU temp.

2> if powering this hurricane of a fan is a problem for the mobo i can splice the power through the manual controller that came with the stock fan. Red and black wire seems like a nobrainer, but with all the $$$ involved here i want to be absolutely CERTAIN i'm doing the right thing.

i'd rather do option 1 and be hands off. be a pain in the @$$ to have to dial it up every time i need to run hot.

BTW so far the fan hasn't seemed to change my temps. Don't get why the heat dissipater is set so far from the socket. Might just go with a nice water jacket and build the coolant system myself.

I have discovered to my sorrow that my own mb - the As.s P7P55D-E Pro, an expensive board - does not have the capacity to control fans with voltage. My previous experience was with Gigabyte boards. Even their budget board - the $105 P55M-UD2 - was able to control fans via voltage as well as PWM. My daughter's rig is running that mb with a 3-pin fan as I write this.

4-pin fan headers are physically compatible with 3-pin fans. They were designed that way. The only question is your motherboard. So, go into your BIOS and see if you have an option to switch control modes. That's where it is for Gigabyte boards.

Good luck.
