Intel Pentium 4, 2800 MHz (21 x 133) 478 socket processor and
Hewlett-Packard HP d530 SFF motherboard, and a noisy CPU fan. In BIOS fan speed on idle is set
2/4 (50C-65C) because my motherboard will overheat (68C) if I set it to
I didn't know what socket it was, but after I took off CPU fan, I realized that it was same.
No problems were while I was installing it.
I started the PC and fan was spinning normal 2 seconds (like with first CPU), but after those few seconds fan was spinning at maximum.
I didn't reboot, because I wanted to check temperatures. After Windows 7 started and installed this CPU (didn't restart system). I checked CPU temp, but logically it was at 25C, the system temperature value was 89C (very high, and Windows lagged very much, maybe because I needed to restart the system to affect on processor drive). I used HWMonitor.
So I went to BIOS to change
Fan speed on ILDE setting but no effect. Also there was a new setting called
allow CPUID maximum value 3 (or something like that) it was set to
disabled. I changed it to enable and fan started to lower speed. After speed wans`t so horribly noisy, I just saved settings (F10) and restarted. But I was disappointed because fan was spinning at maximum.
Now I have old configuration (old CPU and BIOS settings) and nothing seems to be different.
So Im sure that it was CPU problem.
- Since CPU was used in other PC, I will check that PC.
- My fan is blowing to PSU. If I rotate it, I will to need to change wire from
CASE_FANbecause it wont reach
- My PC doesn't have a case fan, so my BIOS is showing
ERROR 512 Case fan not detected
Maybe I should disable SMBUS?
The new CPU was damaged.
