Will do that buddy thank you all for the advices ... Too lazy to repaste this evening :)

- got : Thermalright no name aka chill factor
- Noctua NT-H1
-Artic silver 5

I think the NT-H1 is better than the two other right ?!

Do not use AS5 especially on GPU where there is plenty of ultra small capacitors it could lead to short circuit and then bye bye GPU ;)
AS5 will conduct current and it's absolutely unsafe to use.

usually i iused GELID GC EXTREME or Kryonaut from Thermal Grizzly but no more left at home ...

I used kryonaut too but results were worse than pk3 maybe coz pk3 more thin

Now my results are excellent, cpu only stress test in aida is just 69C

noctua and arctic are similar

So on idle when PredatorSense sense is minimized, with fans at 1000+1000 rpm I have 42C on cpu, very cool and absolutely noiseless

When PredatorSense is in screen it gives 10% load and temp is 55C

@mikolaj612
I checked EC and indeed there are no anything similar to fan curve table

And if it is not in EC then it can be only in bios right?

We need to find a region in bios with group of numbers 29-37-45-53-61-69-77-90 (thresholds from fan curve tables)

Fan curve should be stored somewhere in BIOS.
BIOS should also contain EC firmware inside - so we need to decompile it and then modify - but I don't know how to find it.

@mikolaj612 What do you mean by decompile? We already have dump and I guess those numbers must be placed together somewhere, we can find it in hex editor
Also some tools like UEFITOOL can parse the dump

It looks we need advice from @Lost_N_BIOS how to find that

I'll look into it later ;)

Sorry mate but that is above my knowledge :(
You need to ask someone smarter how to dump EC region or where to look at bios to find fan curve.

@mikolaj612 - Sorry, I don't know why you would get that FW error 7 in FPT, do you get it in DOS too?

I will check BIOS for 29 37 45 53 61 69 77 90 & 1D 25 2D 35 3D 45 4D 5A (And 001D 0025 002D 0035 003D 0045 004D 005A) >> No dice

Got my sweet spot 2 hours torture session and indeed i was unstable before

Now two hours straight, without throttling under maximum workload (aida torture test) for me the sweet spot is 3.75 GHZ speed shift enforced @ VID 1.000/1.071V (min/max) 75 - 83 °C FULLY STABLE @ RAM 3 Ghz at Cas 18 ...

Will stick to that before re-pasting ...

Simple as that i7 8750H's users report same threshold 55W on the forum's threads i saw @ 3.75/80 Ghz so under load 9750H perform worse but better IPC mono-threadded because of turbo running higher than 8th gen ...

PL1 must be 80/90W to run it @ 4ghz no way with 56W ...
With good pasting i think it can run @ 4ghz H24 7/7 ... but PL1 is the limiting factor under heavy load you were right Hyppo ...

Will repaste it tomorow stay in touch !

@Lost_N_BIOS
Happy new year!

Can you pls advise us how can we find fan curve in the bios?

This is the table by documentation, I can confirm it matches real fans behavior




We already can control fans through the EC (using apps RW-Everything or NBFC) but it has only 255 registers to control and obviously those fan curve table is not there, here is screen of this EC



So I suspect those table is somewhere in bios?

@Hyppo - Thanks, Happy New Year to you as well

I've tried to find in BIOS before, and with above noted info too, but I hadn't seen that RW data before, let me see if I can find using any of that.
OHH!! Sorry, I thought you were saying here is EC in RW, use this info doh!

I can't find this in BIOS, looked a few times already It may be programmed directly into the sensor/control chip for the fans.
I even tried to look for patterns of hex using only two sections of that table temps 61 & 69, with or without GPU, and can't find anything even close that matches both (ie both values in same area/file, or all there etc)
And only places I found 2600-2900 or 2900-3200 were in WAV files (audio clips), and none of the info before fan speed was there in any format either, so it's not those in disguise
No luck yet, I think either it's not stored in BIOS or those values are not 100% Exact in the BIOS I checked (1.08), or it's in some encrypted format other than LZMA
