Fan control in Dell workstations...

RoachycaL · 28 Nov 2006 at 18:25

Hey guys,

I need help - I was just given a Dell Precision 530 workstation and Im loving it to bits except I hate noise from pc's espeiclally this one. The 3 fans make a kind of droning sound which is really annoying. Speedfan cant find them and niether can a few other tools ive tried. I tried everest home edition which finds all 3 and tells me their RPM etc but obviously in everest you cannot change the fan speed.

Any help guys? Ive tried unplugging them and it brings up a message in the bios telling me to press F1 which will get even more annoying.

I also noticed the fans use the typical red/white/black cable which means I could plug one of my own into the port on the motherboard if it fitted?

Any help much appreciated as this is driving me pretty insane,

You can only control fan speed from the mobo with a 4 pin fan which has PWM. You could get a zalman resistor to decrease the fan speed or a fan controller?

So a fan controller will be able to control these fans? They are 3 pin - how does the controller connect to the fans? The connector isnt the usual 3 pin connector.

Are the fans cleanish? The ones in my Dell 650 Workstation are whiney when dirty.

Yeah their clean - how noisey is yours as they use the same chassis etc. the "whinyness" is what im trying to describe - its funny because the front fan is completley silent and so are the two 40mm PSU fans *suprisingly*, its the two back fans that are noisey.

I know the sound you're on about...it's a droning whine isn't it.

IIRC, I cleaned the fans and squirted then with some Electrical contact cleaning spray stuff, and they worked better again.

Got a bit furthur - when I take the fans off their stupid clip on system (anti vibration out the window), their silent so I need something to stop them from vibrating off the back of the case - problem is they clip onto the back so I dont think I can put anything inbetween them and the case :confused:
