Abit has asked owners of its AN9 32X motherboards - all of which are based on Nvdia's nForce 590 SLI - to send back their mobos for a free repair. A fault with the boards' heatsink assembly could cause the products to overheat, the company said.

The boards affected by the recall are regular AN9 32X and the Fatal1ty-branded versions with the following serial numbers:

Fatal1ty AN9 32X
FAN93UDC000001 - FAN93UDC002713 FAN93UDD000001 - FAN93UDD001648

AN9 32X
AN932UDC000001 - AN932UDC001407 AN932UDD000001 - AN932UDD001000

Abit stressed the following serial numbers were not included in the recall:

Fatal1ty AN9 32X
FAN93UDC002714 - FAN93UDC005422

AN9 32X
AN932UDC001408 - AN932UDC002612

Abit blamed the problem on poorly fitted heatsinks which could suffer "component displacement due to accidental rough handling during shipments" - it comes loose in the box, in other words. ®
