Artic Freezer Pro 64

Could I have some input please.

Last night I tried to fit the cooler to my Gigabyte K8N51GMF-9/ motherboard.
It fitted just fine, and I connected the 4 pin fan connector to my 3 pin recepticle on the board (the connector has a notch that allows this and ensures the pin cannot be fitted incorrectly.

Anyway, I check all connections, and once satisfied switch on the box.

PC powers up, fan on the cooler powers up, and then the board begins to emit a loud two tone warning. Initially suspected an incorrectly seated CPU, but no. I also checked temps and the CPU showed no signs of overheating.

I tinkered with various bios settings, but to no avail. Whenever the PC boots the mainboard emits this loud noise.

I removed the Artic pro and cpu, cleaned everything up, and then refitted the original CPU cooler. Everything booted just fine.

Could somebody tell me what I might have missed. I do build PC's but this is the first time I've fitted a non standard cooler and I'd like to be sure I have not missed anything obvious. Something tells me that it may be to do with the 3 to 4 pin connection, but as the link shows the 4 pin connector would appear to be compatible with 3 pin fan recepticles.

All guidance greatly welcome.

Go into the bios and see what the warning temperature is, it might be set low.

Also check that the warning your hearing is for the cpu, it could be for the northbridge etc.

Thanks for that. May I ask what the risk would be to the Northbridge?

Some of the fanless northbridges can run quite hot, I think mine is running at 60c (gigabyte k8n sli). I'm not sure of the temperature threshold of the northbridge though, I would have thought 70c.
