Intalling New CPU

Hello All,

I have a HP Compaq CQ70 laptop. This laptop had Intel Dual Core Celeron T1600 CPU. I have replaced the it with Intel Core 2 Duo T7500 which 2.2GHz processor.

I am listing some of the specs of both CPU's for comparison. Note that only FSB and VID Voltage range are different.

The reason I decided to change the CPU is that there is a variant of my laptop (HP Compaq G70) which has same motherboard but core 2 duo T5800 CPU. So I assumed that if replace the CPU with an older C2D CPU it should work.

Now I want to find out if there will be any problems because of this. For example overheating etc.

  1. I have tried to monitor the CPU temperature and it stays at 67C.
    Do I need to be worried
  2. If you're monitoring your CPU temperature in the BIOS, it's roughly the equivalent of it running at full load. 67C is slightly high for a desktop, though I'd think it's normal for a laptop. I don't have much experience with laptops so someone who is more knowledgeable with laptops should verify this.
  3. I have been using the software called Speccy to monitor the temperature.
