CPU Temp question
CPU Temp question
I upgraded my core 2 duo e8500 to xeon e5440 and discovered that most software, except AIDA64, displays temperature readings different from the BIOS. Programs like speecy, core temp, hw monitor, hw info, msi afterburner, etc., show temperatures 15-20 degrees C higher than the BIOS (BIOS shows 25-40, others 40-65). Only AIDA64 matches the BIOS temperature. Now I’m uncertain whether to rely on BIOS and AIDA64 or other popular tools since I plan to overclock my CPU. If BIOS and AIDA64 are inaccurate, my temperatures might be too high for safe overclocking.
I believe I discovered the fix. The issue was with tjmax; my CPU runs at 85°C, but most software sets it to 100°C. I manually adjusted tjmax to 85°C in real temperature and it now matches AIDA64 and BIOS readings. I found this information on the link provided.
There are several temperature sensors available. The BIOS usually includes one close to the CPU socket, though it's not the CPU itself. The software you employ obtains readings directly from the CPU die. I personally rely on Core temp and Real Temp.

I personally check Core temp and Real Temp. Core temp displays 50 idle at 70 degrees under load, while AIDA64 shows 30 idle at 50 under load.
There are several temperature sensors in use. The BIOS usually includes one near the CPU socket, but it's not just the CPU itself. The software you're running provides temperature data from the CPU die. I'm using Core temp and Real Temp. Core temp displays 50 idle at 70 degrees under load, while AIDA64 shows 30 idle at 50 under load. Are you on the same motherboard? If yes, please update the BIOS. The Xeon is a server-grade component designed for long-term stability and not for overclocking.

Why a Xeon? It's a server-grade part designed for long-term stability and not overclocking.
I'm on the same motherboard, updated BIOS and microcode, installed the newest one, and it's giving performance similar to Q9550 at half the price. It was a good upgrade from my Core 2 Duo.
