Let's back up a sec. IBM servers normally come up with all fans at full speed on power on. This is normal behaviour. If the fans STAY at full speed, then that's a problem. If they quiet down after a few seconds, there is nothing to be done.

Won't power on

These rackmount servers are really loud and are meant to be run in a data closet.

Start my checking the ram - remove all but one stick (cant remember if these work in pairs). The idea is to check each stick to see if you have a dead stick.

These servers do a full system check often before you will see any video.

Are you hearing any beeps?

Cooling fan speed

It's not likely that you can adjust the fan speed directly. You might have to use the various power profiles in the BIOS - if this model even implemented them.

The fans are controlled by either sensors on the board or a Baseboard Management Controller - if installed.

It's not really something that you can control. They will ramp up under load and increasing temperatures. That's what they're designed to do.

If it's too loud then this is not for you.

Fan speeds don't drop and are constantly on full power.

Hello here is the homepage:

I had this problem on another pc, it helped by cleaning the whole pc out for dust, with compressed air.
And renewing the thermal paste, between the cpu and the cooling element.

Actual control of speed is base entirely on measured temperature at some appropriate point, and a setpoint. Whether 3-pin or 4-pin, the basic control strategy is the same. For the CPU, the temp sensor is built into the CPU chip. For the case or SYS_FAN or CHA_FAN, the temp sensor is built into the mobo at some point. In each fan control loop, the measured temp from its sensor is compared to a setpoint and used to slow down or speed up that fan.
HOW the speed of the fan is changed is what differs. On a 3-pin system, the mobo reduces the +12 VDC line voltage to slow the fan down. On a 4-pin system, that +12 VDC line is kept at that voltage always, but the special PWM signal is used inside the motor casing to control how much of the time that voltage is actually turned on to the motor. The chip using this signal is a simple on /off switch, turning on the feed of 12 VDC to the motor and turning it off again, very rapidly at the frequency of the PWM signal. That signal looks like a "square wave", except that is "% ON" is varied (not constantly 50%) to control fan speed.

Try also to upgrade the bios, and look for the settings for the fan.
Make sure the fans are connected right, to the mainboard.

Good luck

I have a gateway 9510 server running windows 2003. The system alert light is orange, and the two tops fans are blowing wide open making it very, very loud. It will boot up properly, I just want to make...


Solution for your problem is remove the fan and clean the dust accumalated on the wings, this would solve your problem. Even then if your problem is not solved do replace the fan with new one.

FANs running at full speed system locks up

Fans running at full speed means, the redundant fans start working. That means you have a problem with the cooling system. Check your air-conditioner at your data center.

Fan speed

the fans keep the GPU's and CPU's at an "optimal temperature" that is why they start loud on "over RPM" and then quieten down and speed up again during heavy traffic or similar tasks. its possible just cut the ground wire to the fans. but i deeply deeply suggest you dont! ;) people like myself have desined the systems to operate with maximum GPU life and at an optimal count. good luck.
