stock fan sputters on e6750

[imported_MrPresident]

e6750 with stock Intel fan that came with chip.
Gigabyte DS3L board

When I start the computer the fan sputters. It appears to make a few complete rotations (a quick sputter), then stop for about 1 second, then make a few more rotations, then stop again, etc...

This "sputtering" lasts through the Win XP boot.

Fan is silent, and not making any unusual noise.

Fan finally starts to speed up after Win XP has loaded and is at desktop.

Is this something I should worry about? Is this normal? Any fixes I should look into?

Thank you in advance for any help you might provide.

Don't know if this is normal (my retail e6750 is on the way!), but I suppose you can call manufacturer and ask for another fan (without having to send your "old" fan).

Are you using fan control in the BIOS? Try disabling it and see what happens.

I wouldn't worry unless the system becomes stable due to overheating. Check CPU temp while working and see if fan speeds up. Again, check the setting in the bios.

I've seen this happen when a four pin fan - typically PWM speed control - is connected to the CPU fan header as it SHOULD be but the BIOS is set to use three pin CPU fun (DC).

The stock fan is not that loud so you are probably better off disabling speed control and let the fan run full bore.

After I run the system for a few minutes the fan does eventually start to make complete rotations, and gradually speeds up as the heat rises. It just worries me that in the beginning it doesn't spin at all, then sputters, then mysteriously spins like a champ. I wonder if the fan just can't run at speeds under several hundred RPM. It's like a clock with a dying battery, the second hand twitches every second but never makes it off the marker it sits on, just kind of stuck, but still trying. I'd feel better if the fan just sat completely still until it zoomed up to several hundred RPM and didn't look like it was struggling in the beginning.

I'll try to disable the speed control thing if it's enabled now.

The MB is controlling the fan speed based on CPU temp... there's no problem.

I have the same setup as you but with the AC7 Pro Cooler w/PWM. my fan doesn't run at all on startup sometimes setting the bios cpu fan alarm off. Once in Windows though after a few minutes it starts running fine. I Just disabled the fan alarm because my temps are great.

Yup. As this person and others have said, you are fine. No problems. I have a Gigabyte P965-DS3/Q6600/Freezer7 Pro HSF and mine does the exact same thing.

I have my CPU fan control set to AUTO/AUTO in the BIOS (I.E. PWM) and my CPU fan does the exact same thing as yours.

Once Windows is fully booted the fan auto-regulates it's own speed just fine. I have no issues.

During the first system boot-up we experienced a small situation: we assumed that the processor fan connector was defective. The fan wasn?t spinning, but worked just fine when plugged into another connector. However, soon I remembered that Gigabyte mainboards have pretty aggressive processor fan rotation speed management activated by default. The fan starts spinning very slowly at about 40ºC CPU temperature. We often get caught unawares on this one We think it would make more sense to replace another sticker announcing extreme durability of the platform due to solid-state capacitors with the one warning that CPU Smart Fan Control is activated by default.
