Dust in heat sink

What can four years of not cleaning do to your CPU’s heat sink?

The CPU was reaching temperatures of more than 100 degree Celsius at which time it would reboot.

Upon opening the heat sink was found to be clogged with dust. Cleaning it resulted in collection of this much dust:

2010-11-11 10.42.54

2010-11-11 10.43.18


1) Clean your heat sink regularly

2) If your PC abruptly reboots, it maybe time to clean the heat sink

My PC has been running smoothly since with max temperatures going only upto 60 degrees C.

London Eye.


This has quickly become one of the symbols of London. At night, lit in resplendent colours, it shines brightly over the Thames river.

Windows Live Writer Test.


This is a post just to test if I can publish to blogger from Windows Live Writer. I have heard good things about this piece of software and hope it lives up to expectations.

Modulo 3

Taken from Codercorner..
Thanks to Christer Ericson, one of the fastest way to do:

int Index1 = n; // 0, 1 or 2
int Index2 =
int Index3 =


int Index1 = n; // 0, 1 or 2
int Index2 = (1 << Index1) & 3;
int Index3 = (1 << Index2) & 3;
