Hardware Fan at full speed all the time

[viviexe]

Hello,

I have been using my switch since launch and have gotten atmosphere running on it. Recently the fan has been going at full speed all the time...

I have checked the internal temps and it never goes above 55 degrees and it start the heavy fan work at 40 degrees. I have tried opening the console up to replace the original thermal paste with some arctic silver. It helped a little but the fan is still very aggressive. It worries me to play portably . Is there something I can do with software or hardware that would reduce the fan speeds?

I have a secondary switch for online play so I can get the fan part from it if that would solve it as well.

Any info on how the fans work would help as well! thanks

You should still be ok to play portable.

The other thing you could try replacing the fan unit completely. I did this along with new thermal paste and heat pads on the RAM chips and my switch is cool only time fans ramp up is when I am playing games where i have asked it to overclock because of mods and even so it never goes above 55 odd.

I think the switch has a cut off of around 85/90 degrees anyway.

Does this also happen on SysNand? Just wondering if you might have a custom fan profile installed.

Thank you @burhansalih. I will start looking into replacing the part. Will let you know if it works

@fallguy441 I just boot in using fusee-primary, does that automatically go in SysNand or EmuNand ? I have been banned from online so early it didnt matter trying to tip-toe around nintendo haha

can I use a custom fan profile to make the fan relax ? if so where should I look to find out how

if you look under the system tab once you boot into atmosphere if you have an S at the end I think that means your on Sysnand..

I don't think custom fan profile is being used unless your using sys-clk in which case you would know.

surely he'd remember doing that?....And by default AMS doesn't mess with fan speeds.

So yes I am on sysNand. I currently do not have custom fan profile but I use sys-clk as a .nro to check my temps.

I will investigate this so thank you very much for all this info I havent looked yet but i assume if i want to use custom fan profile i need to be in emuNand right?

yea, it was just an idea. Might be interesting to see what status monitor overlay is showing in the fan percentage value.

Hi fella, no you can use sys-clk on both I thought...although I only ever use it on Sysnand....
