I have a GIGABYTE 7ZXR motherboard with Athlon 1,33 GHz (Thermaltake 6Cu+ cooler) and 512MB Kingston SDRAM, Maxtor 30GB (7200rpm)!!!! The processor is not overclocked and i'm not using RAID!!!! There was a small fan on the chipset (northbridge) which recently broke down an i took it off!!!!My question is if this fan is really needed or if i will have any problems without it!!!! So far i haven't had any problems!!!! If anyone has similar experiences PLEASE POST ANSWERS!!!!
