If it's 71°C then it looks like your fan isn't working fine!

It could be clogged up with dust.  Dust is not your friend, if the fan 
is dusty say between the metal fins then it works like a blanket, air 
can't get through and cool the fins down so it gets hotter and hotter.

You might also need to apply a fresh coat of heatsink compound.

What CPU do you have by the way?

You may even want to look at replacing the cooler with something 
bigger/better.  You don't have to go too expensive but you should be 
able to get a reasonable fan for around £10 to £15 online (or possibly 
nearer to £20 to £25 from PC World).

Personally I have a nice big Zalman fan...


It wasn't cheap (traditionally I've not spent any more than about 6 or 7 
quid on a fan) but it cooled down my hot Phenom X4 and it's now in the 
wife's PC cooling down her overclocked Pentium Dual Core.  It's silent 
too (although it has sharp fins).

I've also used something like this before too which was pretty good:
