Crysis draws a lot of power, if your cooling isn't strong enough to deal with the extra heat its gonna bite you in the ass HARD. Especially in the long term. (total hardware failure, can be very expensive)

What?
If you're talking about CPU/GPU power, it can only take those up to the limit of the hardware, if a comp can't handle the resulting, there's a fan already broken or on the verges of breaking, or the CPU/GPU is horribly overclocked without adequate extra cooling installed.
If you're talking about electricity, again, if the power supply can't keep up with it's system running at full capacity, it's cooling is either failing or someone cheaped out someplace they shouldn't have...
