I built a new comp a few days ago and installed the HSF that came with the P4 cpu in a box, then i realized i didnt remove the protection thing at the bottom on the heatsink. I removed the HSF and installed it again using thermal paste because the pad was destroyed. My CPU temp just hit 62 before when i was Playing a game and the temperature alarm went. This has got me very worried. what can i do ?

<<installed the HSF that came with the P4 cpu in a box, then i realized i didnt remove the protection thing at the bottom on the heatsink>> If the processor is from Retail Pack, there is no protective thing at the bottom of the sink. There is, however, a layer of thermal pad which you don't peel out. <<I removed the HSF and installed it again using thermal paste because the pad was destroyed.>> Hope you gave it a good cleaning before you applied thermal paste .... and not too much of it. <<My CPU temp just hit 62 before when i was Playing a game>> It is pretty normal for a 2.6C to hit 62C when playing game. It has a max Tcase temp of 75C (top center of the processor). <<the temperature alarm went.>> It is you who set the alarm when to go off (in BIOS setting). It is recommended that you have intake and exhaust fans. Keeping board/system temp to below 35C whenever possible and making sure your power supply is rated for your system.
