Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

This is something that I've been seeing on older ubuntu versions, too. I bought a new laptop recently and am seeing the same old thing.

It's Asus K53S with i7 2670QM processor, 8G ram and a somewhat slow HDD (5400rpm). While surfing the web with ~5 tabs, on windows, my core temp is on avg ~51C, and on ubuntu it stays at ~56C.

When installing new software etc it gets higher, but I guess it's something to be expected.

Any ideas why the difference and can I somehow lower it (without undervolting)?

You can use jupiter, it lowered my cpu temperature significantly. Plus you should check threads in askubuntu, similar question was asked before. – Vinit Jul 27 '12 at 8:18
