Thanks to Kease.

He was the one who had informed of this mod. On the intel retail hsf there is a little black nub located on the fan hub covered in shrink wrap. If you open this, you'll see that there is some sort of thermistor on it. Kease had told me to solder or snap it off, but I did neither of the two. Instead I just got some pliers and crushed the thermistor itself. By doing this I did not break off the actual PCB that the thermistor sat on. It looks really clean, as if the thing wasnt there before and the PCB is still intact.

By doing this the RPM of the fan will increase drastically and therefore increase cooling. My fan use to run as low as 3200rpm and getting temps at around 45C full load, but now with this mod the fan runs at 4600rpm!! And it keeps my CPU cool at 35C, thats a full 10C lower!!. I might also add that I am not using Aritc Silver2 or 3, just plain thermal paste and the heatsink is not lapped either!.

So for people on a tight budget with a reatail Intel HSF, this mod is for you. It will only cost you a whopping 5 mins of you time!!

*Note* this will void the warrenty of you HSF
