If your PC still operates, your CPU is not damaged. If a CPU like your's does overheat, it will shut itself off before it is destroyed.
I can't believe your PC store did not ask if you wanted to buy and install or have installed a new CPU cooler/fan. You don't need a fancy one, the store should of had all kinds of stock Intel CPU coolers or similar ones available. Can you afford the $20 to get one and install it yourself or have someone help you with that? Don't you have any PC geek friends that can help you? Anyone with experience could change the cooler in an hour, and you'd have your PC back.
Find someone that can help you, with the BIOS settings too. If you're dealing with the store to get warranty service, you'll be waiting for them. What warranty did the store provide?
Thanks for the reply,
Instead of replacing he somehow increase the fan speed to its max RPM...
And with BIOS settings..
I checked through every setting on my BIOS system and the only thing i found was the
CPU FAN which i changed from *ENABLE AUTO
to *DISABLE which said it will give my CPU FAN MAXIMUM RPM..
I was worried about warranty only because i was afraid my CPU could have been damaged, but seems like its ok accoridng to you..
They said to get warranty, they will need to ship my CPU to SINGAPORE (i live in AUSTRALIA) which would take at least 2-3 months..
The only warranty i had was the one that comes from intel, the one that comes with every CPU..
i will get a new CPU fan and let you know what happends =]
