Actually, the fan shroud is a very important part of the system. When combined with the fan, it creates a vacuum that sucks more air through more of the radiator. While you might be okay without one, you are better with one. And, as the radiator slowly clogs over time, the absence of a shroud will cause a problem. There is no guarantee that a shroud alone will solve your problem, but it will definately make a difference. They don't put them there just to protect your fingers!
Take care,
