I have just replaced a motherboard and heatsink and fan. The processor idles at 36-38c in the BIOS after restarting from Windows. I am concerned these figures are too high. What do other people think?
 
Normal cpu tick-over temp is about 26-37 degrees Celsius depends on cpu heat sink fan ect ect

Here are the maximum temperatures for some CPUs.

AMD Athlon, Athlon 64, Opteron, Duron and Sempron
All Slot A CPUs (Athlon classic, Athlon Thunderbird) 70°C
Athlon Socket A up to 1 GHz, Duron up to 1.3GHz
90°C
Athlon "Thunderbird" Socket A 1.1GHz or more 95°C
Athlon MP 1.33GHz or more 95°C
Athlon XP up to 2100+
90°C
Athlon XP 2200+ and faster
85°C
Duron "Applebred" 1.4G and faster 85°C
AMD Opteron
69 or 70°C
depending
on model
Athlon 64, 64FX, Sempron
Most models 70°C; 65°C for some Socket 939 Athlon 64 models
Athlon 64 X2 (dual core)
65°C


AMD K6 series
All K6 CPUs (166-300MHz) and most K6-2/K6-III CPUs 70°C
K6-2/K6-III CPUs, model name ending with X (e.g. K6-2-450AFX) 65°C
K6-2-400AFQ (uncommon) 60°C (!)
K6-2+, K6-III+, most mobile K6/K6-2 CPUs 85°C
mobile K6/K6-2 model name ending with K (e.g. mobile K6-2-P-400AFK) 80°C

The temperatures specified for AMD CPUs max case surface temperatures. These CPUs do not have an internal diode to measure CPU temperature. The accuracy of the CPU temperature measurement depends on the motherboard; therefore, it is possible that the CPU overheats even though the CPU temperature reported by the motherboard is below the specified maximal temperature.

Intel Pentium III
Pentium III Socket 370 500-866MHz,
Pentium III Slot 1 (first generation, OLGA) 550-600MHz,
Pentium III Slot 1 ('Coppermine') 500-866MHz 80-85°C depending on model
Pentium III Socket 370 and Slot 1, 933MHz 75°C
Pentium III Slot 1 933MHz 60°C (!)
Pentium III Slot 1 1GHz 70°C for newer versions
60°C (!) for older version
Pentium III Slot 1 1.13GHz (first version) 62°C (!)
Pentium III max temperatures are the maximum temperatures reported by the thermal junction inside the CPU.

Intel Celeron / Celeron
Celeron 266-433MHz 85°C (max. CPU case temperature)
Celeron 466-533MHz (0.25µ) 70°C (max. CPU case temperature)
Celeron 533-600MHz ('Coppermine) 90°C
Celeron 633 and 667MHz 82°C
Celeron 700-850 MHz
80°C
Celeron 900MHz-1.4GHz
69-70°C depending on model
Celeron 1.7GHz and faster
67-77°C depending on model

Celeron max temperatures are the maximum temperatures reported by the thermal junction inside the CPU, unless otherwise specified.

Intel Pentium II
Pentium II (1st generation, 'Klamath') 72-75°C depending on MHz
Pentium II (2nd generation, 2.0V core), 266-333MHz 65°C
Pentium II (350-400MHz) 75°C
Pentium II (450MHz) 70°C
Pentium II temperatures are the maximum temperatures of the thermal transfer plate (on which the heatsink is installed).

Intel Pentium 4, Pentium 4 Extreme Edition, Pentium M
Pentium 4
Max. temperature depends much on model and clockspeed, but no clear pattern is visible. Consult Intel's tech specs for information on your particular model.
(Lowest: P4 Extreme Edition 3.2GHz with 64°C, highest: P4 Willamette 1.8GHz with 78°C). 64°C - 78°C
Pentium M
100°C (!)


Intel Pentium D (dual core)
Pentium D 820 (2.8GHz) 63°C
Pentium D 830 and 840 (3.0-3.2GHz) 69.8°C

Note: Pentium 4 and Pentium D temperature specifications indicate the maximum cover temperature, which is typically lower than the temperature reported by the internal thermal diode. Therefore, your system may be running fine even if the reported "CPU temperature" in the BIOS is higher than the temperature specified here. This does not mean that you're on the safe side, though.

Intel Pentium Pro
Pentium Pro, 256 or 512K L2 cache 85°C
Pentium Pro, 1MB L2 cache 80°C
 
Thanks :).

I will keep an eye on it once I reload windows and install some monitoring software from the motherboard CD. If this was a desktop I would not be concerned but is for that SLI setup mentioned in previous threads.

I would imagine it is a 65mn chip too and not 4nm.
 
Just got it down to 32-35c now. I tweaked the BIOS settings to cool over silence and fitted an 12cm case fan which seems to aiding cooling.

The motherboard chipset is very hot though and the manual warned me against installing a fan on the chipset heatsink unless a passive CPU or water cooler was used. I have not heared of that before but it is all to with air flow.

The system has gone through two motherboards in four years and I suspect it is because the system has been running hot.
 
Just reinstalled windows and I have ran Prime 95 for 90 minutes. No errors and even when that was running I was able to still browse the web desptie the processor usage being at 100%.

I use core temp to measure the temperatures and they idle (in windows) at 28 and 31c and they rose to 44/46c under the stress so I am not worried about overheating. The only slightly issue is it is winter so it would run cooler than normal anyway but mostly the cores we running at about 42-44c under stress as when it peaked at 46c they cooled down a bit.
 
I'd be more than happy with those temps. Only worry when you start exceeding 65c under load, as this is over Intel's "recommended" max temp.
