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.

  1. [b]
  2. Processor Number T7500 T1600[/b]
  3. # of Cores 2 2
  4. # of Threads 2 2
  5. Clock Speed 2.2 GHz 1.66 GHz
  6. Cache 4 MB L2 Cache 1 MB L2 Cache
  7. Bus/Core Ratio 11 10
  8. Bus Type FSB FSB
  9. System Bus 800 MHz 667 MHz
  10. Instruction Set 64-bit 64-bit
  11. Lithography 65 nm 65 nm
  12. Max TDP 35 W 35 W
  13. VID Voltage Range 1.075V - 1.250V 1.075V-1.175V
  14.  
  15. Package Specifications
  16.  
  17. TJUNCTION 100°C 100°C
  18. Package Size 35mm x 35mm 35mm x 35mm
  19. Processing Die
  20. Size 143 mm2 143 mm2
  21. # of Processing Die
  22. Transistors 291 million 291 million
  23. Sockets Supported PBGA479, PPGA478 PPGA478


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.

I have tried to monitor the CPU temperature and it stays at 67C.
Do I need to be worried

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.

I have been using the software called Speccy to monitor the temperature.
