The song of the Athlone has been well aired in the Helproom. That howl that seems to come from deep within the soul of your PC- but it seems is infact the CPU cooler. All the chat back and forth never did solve the problem seemingly -clean the fan /oil the bearing etc., But all this related to older well used machines. Imagine then my thoughts when my nice new 64bit Athlone MoBo from Novatech- started to sing! So I emailed support at Novatech and said er 'scuse me my CPU is crying - do I have a problem? Next day an Email from Dan in Tech seupport said oh Really1 I'llsend you a new one right away. And he did it came next day! Well done I say.
