i wander how to change gpu fan profile so it will be more power to fan in certain temperature so my card gets cooler

I already posted this on vogons.
Its a 3d printed custom bracket for socket 478.
I used this AM4 bracket as a base design.
Its to be use with cheap generic clip based cpu cooler.
Reason for doing this is:
- Its hard to get/find a good copper base cooler. Even if you find one, the price is ....
- New generic cooler is cheaper and can use bigger fan (less noise)
I tested the bracket with cheap chinese horizontal cooler + fan taken from CM hyper 212 evo.
The processor that I was using is P4 2.4Ghz prescott.... -
Got a new victim:
AcuRite 5 in 1 Iris outdoor weather station not updating the temperature / humidity anymore. The original sensor is a SHT21. Also there are identical other sensor manufacturers. I chose the HTU21D to replace the original SHT21. Both have identical specs. I've had two failure modes with these sensors.
A: outside temp stuck at -40?
It's cold here at times in Canada, but not that cold!
B: stuck at some temperature and maybe updating once in 12 hrs or so.
Easy solution is to go to AcuRite website and purchase the sensor. Right?...

What temperature with the heat gun should be use to remove large and small chips from the laptop and mobilephones motherboard? My problem is that the chips not easily remove from the motherboard, example 380°C degrees. I don't know if there is a difference with the devices that the temperature is not stable with them even it shows the right temperature, what should it be? I don't know if I should use higher temperature but the risk of destroying other components?
I have device Sugon 202. I'm used also normal flux and rosin flux.09-12-2023, 12:44 AM -
Hello,
I bought from China ISL95880HRTZ (3+1+1 Voltage Regulator with Expanded ICCMAX Register Range Supporting IMVP8 CFL/CNL CPUs) chip, which I think is not the original one, but anyway, I tried to resoldering it with a 380C hot air station. Seems soldering is pretty good, but the laptop doesn't work (it worked before, but still had some problems with power delivery).
Is there any big chance, that they sent me two fake ISL95880HRTZ chips or did I just use too big temperature for desoldering? I will try with another chip, but I can't find any info about the maximum desoldering... -
Hi, I'm seeing one 9V relay having temperature 40C on its 9V (primary) side. Does that seem right? I switched 2 relays on that board and the temperature was the same (on the same position), so I'm sure it's not a faulty relay. I measured voltage on that relay and it was 9.5V DC, so that looks good. I don't see any other relay on that board having that kind of temperature and they have 9V on them too.
I thought maybe the transistor that is switching this relay keeps switching on/off, so I also checked for AC and there was almost none: 0.3V using mV range. No steady frequency was shown, but...
