Those are normal temps. Idle temps around 50-60C are decent operating conditions. Put it under load and see how it does.
Typically, the working temp range on Intel chipsets ends at 100C(at which temperatures, cpu's should last a decade plus). If you're busting 200F in an air conditioned environment with the laptop positioned for full ventilation access, it's time to do some corrective work and clean that sucker out. 180F under load is a pretty typical result for a laptop. That said, four tabs in chrome and a music player doesn't seem like it should count as under load. I call that idle.
You may have other problems, spyware, etcetera. Your system is about a third the speed of mine, but that should still be pretty damn near idle. I've got a lot more than that running right now and I'm running at 0-3% on the cpu front.
