help ! CPU too hot high degree celcius

first of all I am newbie please be gentle with me
my problem is CPU works too hard on latest Desmume

me use latest Desmume build r5561 x64
I use this setting :
- 2x HD scalling 3D using Softrasterizer
- Filter Nearest +1.5X
- CPU mode JIT tolerance 2
- Sound Sync method N, DIrect Sound Interface Linear buffer 5880
- Display method DirectDraw HW

don't tell me to downgrade my setting, I really like that setup (list setting in above)
hence - I don't intend to provoke Desmume developer in my next statement. Because I noticed if I mention X432R in here I will not get good response
I am very very Thankful for what you doing, I really meant it, please bear with me
I believe Desmume X432R have option like this : "CPU Power Saving"
and it really did wonder !
the difference is significant
by default x432r using the same setting as above (3D, sound, but without filter) my CPU is around 63 - 67 degree Celcius
then I turn on "CPU Power Saving" feature, now my CPU is around 55 - 60 degree Celcius never go beyond than that number (the difference is great right ? )
but if I use latest Desmume with the same setting, my laptop is around 69 - 76 Celcius !! and my laptop fan is running amok like crazy, because it is HOT
BTW
I not use X432R anymore !!
because the development Stop and can't support Magnification filter like latest Official Desmume
so going back to x432r is a big no no for me

so please,
can official Desmume have option for "CPU Power Saving" in the future ?

No. I'm skeptical that CPU power saving does anything except when paused.

Re: help ! CPU too hot high degree celcius

I did test just now, CPU Power Saving from x432r did work

here is the result

I am just user
so I just can hope this feature is realized if possible

Re: help ! CPU too hot high degree celcius

Thanks for taking measurements, but that's within the margin of error (I estimate it to be 0.5% faster in the 'with power saving' graph), about what I expect for code which appears to do nothing at all. I'm not adding code which does nothing at all.

Re: help ! CPU too hot high degree celcius

sounds like you need to redo your thermo paste on your cpu i reccomend Kryonaut or aeronaut thermo compound.  Also if you cpu heat sink is dirty try cleaning it out with a paint brush and vacuum.

Re: help ! CPU too hot high degree celcius

hi finto !
I did maintenance sometimes, I use good thermal paste too (I forgot the brand) the paste color is gray
my Lenovo Y410P is easy to dissamble, for fan cleanup purpose
in normal use my cpu is around 42 - 50 degree celcius, built-in windows 8
and you can see in my temperature test,
in my setup Desmume latest is using more cpu power, while Desmume x432r is more cool. I don't know why is that

Because it's different software with different optimizations, different features, and different methods used to implement those features, for chrissakes.

Alright so you have good thermo compound? and its clean.   but its a laptop. laptops always seem to run hot. have you tried to change you fan speed settings in your bios?  you can also try one of those cheap external fans.

ill put it this way desmumue is a heavy program and probably always will be.  so it will always run hot.

in fact  i used to use desmumue to test cpus in my shop by opening several windows for the emulator and leave it running to ensure its cooling properly and not freezing.

Re: help ! CPU too hot high degree celcius

LOL
what a strange way to test CPU you can use some benchmarking programs maybe ? I recall there is option for CPU stress-test something like that in benchmark software
anyway
am using external fans
this ---> http://www.deepcool.com/product/nbcoole … _509.shtml
and this ---> https://www.aliexpress.com/item/Free-sh … .19.KKu0nY
I believe my machine got enough care and maintenance

regarding my temperature test, latest Desmume is stable at 69 degree C
and I noticed that x432r is always run more cool than official (stable at 63 degree C)
so I hope official Desmume can surpass x432r in the future,
with better optimization maybe ? I am not technical person so I don't know much about this, don't take it seriously
like I said, I really thankful for what you did

Re: help ! CPU too hot high degree celcius

No programmer on desmume has ever checked his cpu temperature while working on desmume, and no programmer ever will. We actually consider it great success if we get your CPU hot, that means, whatever we're doing, we're most efficiently using your CPU to do it. A cool CPU is a CPU running a game slower than it otherwise might.
