Since I migrated from F17 to 18 by doing a fresh install (only kept /home) I've been having overheating problems randomly. For absolutely no apparent reason everything heats up and reaches temps like:

> sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +73.0°C  (crit = +103.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +73.0°C  (high = +86.0°C, crit = +100.0°C)
Core 0:         +66.0°C  (high = +86.0°C, crit = +100.0°C)
Core 1:         +65.0°C  (high = +86.0°C, crit = +100.0°C)

asus-isa-0000
Adapter: ISA adapter
temp1:        +73.0°C  

nouveau-pci-0100
Adapter: PCI adapter
temp1:        +60.0°C  (high = +95.0°C, crit = +105.0°C)

at the same time htop shows average cpu usage to be 1% (not sure how to check gpu usage) so I see no reason for the temps to be this high.

Note: I did not have this problem with F17 ( everything was mostly under 50°C )

What's causing this and how can I fix it?

EDIT: Laptop specs:

Intel® Core™ i5 2450M
4GB RAM
NVIDIA® GeForce® 610M 1GB

Maybe your fans are not being turned on. They can be controlled with the i8k tools (i8kmon, i8kctl, i8kutils).
