I wish there was an answer to this as well... anybody that claims it worked doesn't respond, I have not had any luck manually changing it or with FanSpeedFlasher

I modded a fanspeed xex from the "Usual places" to 100%.

Edit: Here is the patch http://www.ddxcb.com/crap/patcher.rar. Note to MOD/Admin this is legal, its a patch. Or remove it idc.

Get the fantools.zip from _old in the usual places and patch the Autospeed.xex from that one and it will work.  The Autospeed.xex from FanSpeedFlasher.rar will not work and will give the Cannot start game error.

I wish we could get like 5% increments from 70 to 100.  That would rock.

Or better yet an app to control it dynamically on active running system then hit set and it sets in nand.

I can report I now have a Jet in my room.

GPU temps are 20C cooler in XeXMenu... 49C down from 70C

Thanks ddxcb

Thanks ddxcb.  Much appreciated.  I tried 44speed and 70speed from Fantools.zip and both the dev and retail paths in FanSpeedFlash.rar and they all keep the system at about the same temp after 30 min in XeXMenu as Autospeed.xex or an unaltered config.  

The 100speed.xex I created above using your excellent patch and the Autospeed.xex from fantools.zip worked perfectly.  Also, the 00speed.xex included in FanSpeedFlash.rar (stopped fans dead).

Auto value as normally found in the config which can be checked against original nand by issuing command: "nandpro orig.bin: -R16 config.bin 3de 2" and then open config.bin in a hex editor and go to offset 0x4011 it should be 7F 7F

Auto speed is 7F 7F (I know I said that already.)
Fan speed fixed speed range is 80 to E4

After looking more closely it appears the reason is that 44speed and 70speed set the values without adding the 128 dec.  A minor bug.
7F 7F for CPU and GPU fans - Autospeed.xex
80 80 for CPU and GPU fans - 00speed.xex
2C 2C for CPU and GPU fans - 44speed.xex - should have set to AC AC for 44% constant speed
46 46 for CPU and GPU fans - 70speed.xex - should have set to C6 C6 for 70% constant speed

E4 E4 for CPU and GPU fans - 100speed.xex as created using ddxcb's patch to autospeed.xex from fantools.zip

What hex values will represent 80 and 90 % fan speed?

So if I extract the rawconfig in nandpro with -R and then hexedit at offset 4021 and 4022(for jasperBB) the values to what NotMe metioned. Then write that file back with -W in nandpro? Will that work?

Sadly No because the Fan config block is signed in some way and the only way i got it to work is to moddifyied the fan.xex

I can confirm the above patch works. I was speaking to IceKiller on IRC and he was going to get it added to xbins

Great Work
