Hi All,


I have a gygabyte P35-DS3 motherboard and an Intel Core2duo 6550 on it.
Yesterday, i turned my pc on and a spike burned my psu, making it explode. The machine was dead. I changed my psu with a new one and everything went ok.
But, with a friend of mine, we noticed that the cpu fan now runs at 450-530 rpm.
We thought that the spike burned the fan as well and changed it with a new one. Same result.
My friend told me that maybe my board is burned too.

So, i turned on all the alarm in the bios menu: now the pc makes a noise when fan doesn't start (and, indeed, it makes a sound at boot till the fan doensn't start, after 10 sec.) and when the cpu temperature is more than 80 C.

During office application, the cpu runs at 40-45 C. I tried to launch a couple of videogames and everything is fine.

So? Suggestions ?

thanks a lot

You can try using a 3 pin to 4 pin adapter, and connect the fan directly to the power supply. It's cheaper than replacing the motherboard. I also use zalman "fan mate 2" rpm adjusters. These work with the board 3 pin plugs. However, they won't compensate for a low rpm due to a board problem. The maximum setting is just what the board is running.

Thanks for the answer.

But do you really think my board could have been harmed by a spike only in this single feature (the fan rpm) ?
it's really strange.
