ai or aida/Everest doesn't read mine either. But a massive drop in temps for a small fan. I just used a screw from the antec 620 fans to hold it in place

Flashed the board with AFUDOS from AMI. Not the ASUS flasher, lol.

(Wanted custom DMI tabling because ASUS leaves so much BS behind "To be filled by OEM"). Needless to say AFUDOS /b /p /n /k pretty much wiped everything off the board. Including it's internal serial number (which is not the same as the number printed on it), the system GUID and the LAN MAC address. Took me a while to fix that. LOL

remind me never to do that lol, connected up the 200mm side fan and results are in, this is again a 3 min test using adia for timer and hw monitor for nb temps.
connected up the 200mm fan to my side panel and i now get 33c on the nb 36 on the cpu and 21 on cores.
it shows that the cpu temps decrease when airflow around the socket but cores are staying similar which is the temp i watch for, if it affected the core temps and not the cpu then i would say cpu temps are more reliable.
anyways a roundup:
50c 41c and 22c (nb,cpu,cores) with no fan and side fan connected the deltas are 8c nb and 8c for cpu
43c 40c and 23c (nb,cpu,cores) with fab no side fan connected the deltas are 2c nb and 7c cpu
33c 36c and 21c (nb, cpu,cores) with fan and side fan. the delta is 0c on nb and 9c on cpu.


edit sounds like the deltas for the cpu show that the temps on the cpu arnt affected by the fan but i beleive it aids in the cooling

forgot to get the screenshot before closing

CPU temperatures are more reliable, as that is what AMD uses for their maximum TDP and thermal specification. wink.gif

And yeah, I really don't recommend AFUDOS on the C5. LOL.

see i got told that core temps are more reliable under load especially after 45c but cpu temps are better at idle. i can see the pint cos my cores say 8-12c and cpu 27-32c at idle.
just oc my cpu to 3.5 at 1.25v and nb at 2500 and temps are a tad better on cpu and better on the nb, used see close to 60 not seen near 45 yet.

They are most accurate at "45C", but they are not a tangible number. The temperature reported as "CPU" or "Socket" is the sideband value delivered to the socket from the CPU (THERMDA and THERMDC diode measurement points), and this is physical temperature, not an equational control used to monitor the processor.

The cores are rated to run 70C, where as CPU TCase is rated for 55-62C (90C and 70C in some chips cases).

so with mine bein the 95w version i should be ok upto 70 on cpu then not cores i hit 45 at 3.5 at 1.25 on cpu as is that seems high.

Lower VID chips have higher leakage when overclocked, so yours might get warm. 71C is the TCaseMAX for the 95W 1055T I believe, core max is like 90 for that chip, lol.

god i got it 4ghz once and had the cpu at 60 and the heat coming out the noctuas off the h100 was worrying, when i rest bios back to stock my cpu voltage is 1.35 i can set it to 1.15 n lower stable at stock and aida shows the vid at 1.2v, im guessing if i had a 125w id be better off

1.2VID is pretty damn low, lol.

My chip's stock VID is 1.30, it was from a very early batch and it's a hot running power magnet that overclocks pretty nice. biggrin.gif

60C CPU is about what I get at full load running 4.2 @ 1.475~1.500 vCore

Edit: My chip is also 136W TDP
