actually it may very well indeed affect the fan (most likely the cpu heatsink)...if LW is hashing a lot of files or eating a lot of cpu % then that will heat the cpu and thereby speed up the fan if quiet technology is being used on the machine (that being that the fan speed is set to variable dependent upon the cooling required as pertains to the temp of the cpu)...

as ukbobboy01 noted if its noisy then your fan is most likely on the way out...fan bearing can sometimes be lubricated but its probably a better bet just to replace it...if it is a cpu fan then it is probably integral to the heatsink and the whole thing will have to be replaced which will be a challenge if you are not familiar with the routine...
