   What the title of the thread asks. If it matters, specifically a Toshiba Satellite L40-18L. I'm aware there aren't whatever "normal" programs that can ascendence this computer's fan speed, like Speedfan and others, merely since RW is a primary type of program, I'm wondering if in that location happened to be a person that managed to find what numbers you have to change ready to get fan control in the Embedded Restrainer section.

   Also, are there any world-shaking dangers in fiddling with the Embedded Controller values, by from accidentally determination the correct numbers by unselected run a risk and turning off the rooter, not realising information technology and overheating the CPU?

   1. You have to hack writer/check the acpi_fan_control settings in the bios

   Get a BIOS Editor in chief and perhaps you volition see the string for the buff control alternative. Evoke the BIOS with one of Andyp´s BIOS Tools. Open the twine with a Copyreader and maybe you will visualise the settings for the fan speed etc..

   2. You will have to redifine the rooter control settings in the bios and flashbulb the modified bios.

   I dont know how to do this...

   3. Get a Laptop computer service CD and hope that at that place is a; test fan; option

   I did this with my FSC T3010D because the fan was working ``unnormal´´ and i had got this maintance Candle from my friend wich contained a fanH.bat (for high-stepped speed) and a fanL.bat (small amphetamine) and a fanO.lick (fan off).
   I just copied them on my background and used them when necessary .

   fanBOOST v1.00 enables extremity control of the sports fan of the cpu-cooler on toshiba planet L750 + ????

   available at: Dev-Host - The Ultimate Free File Hosting / File Sharing Service

   commandlineswitches:

   none trayicon see
   -a1 set auto mode
   -a2 primed auto BOOST
   -b1 set BOOST 1
   -b2 set BOOST 2
   -b3 set BOOST 3

   for the substitute to routine you need to download and install rw-understand & write utility freely available at RWEverything | Read & Write out Everything

   the sourcecode is enclosed to easily adapt for evt. variation in adressing among different models.

   ON THE ISSUE..

   along toshiba-laptops the fan is solely contained by the integrated controller (ec), indefinable in the acpi-table and thus not recognised by a wide range of available fan moderate computer software. and information technology's non as easy to obtain insight into the dynamics of the control system of rules, As the ec-firmware ain't readily available for decompiling. hence you have to observe how the ec-registers behave and identify the significant bytes. you can Doctor of Osteopathy that as intimately as change the registers with rw-read &adenylic acid; write utility.

   and then to see to it the upper of the fan you can cover registers in the ec, changing the mode of operation.
   on my toshiba satellite L750 the default operation is a four step thermally toggled automatic regulation with rpms ranging from 0 to 4200, the final step kicking in in a higher place 70c, the bottom below 40c.
   when you are on the final step information technology is thinkable to boost the speed to 5100 rpm by mount the value 0x04 in byte 0x55 in the Common Market-register.
   the fan will speed down again below the downward threshold to tread 2 at 65c.

   you can too get constant hike hurry by setting the value 0x07 or opt slightly little noisy overspeeds aside 0x0b surgery 0x09.

   an upside-down tachoreading can equal study at word 0x5c + 0x5d and the Celsius temperature at byte 0x58.

   of class there English hawthorn be no simple lengthwise relationship betwixt raises in fanspeed and cooling system ability.
   in my experience, though, the boost speed enhances the cooling event enough to hold out both the graphics core (which is located at the far end of the heatpipe) and the common processor cores well below the point of intels internal processor outflow throttling at 100 C playing prevalent games.

   in a 3x6 Fukkianese full cpuload throttlestop bench run flying at 2200mhz dissipating 29-33w (rising with temperature) the auto cooling goes 93c while fanBOOST level 3 goes 85c for the max core temp.
   on top of a laptop cooler automobile mode goes 91c while boosted goes 82c.
   so fanBOOST lowers the temperature difference to the surroundings (24c) past 8c while the laptop cooler gives a 2c pretermit.

   the laptop cooler basically supplies fresh air for the intakes while fanBOOST increases the flow through the radiator.

   during the benchmarks the temperature drop crossways the processor was 6c. from these temperatures basic cooling possibility tells an 11% effective rise in air flow between the auto mode and the fastest boost speed. and a corresponding grow in chilling force.
   the acclivity in factual airflow from the motorial fan ought to be of the order of the mount in speed of 21%. the difference from the observed is believably mostly due to the temperature drop along the heatpipe 'tween processor and radiator.
   in a superficial way along the same line the telling uprise in cooling power due to the laptop cooler can be estimated to 3%.
   but the laptop tank is quite an scra more tranquil though impractical.

   i preceptor't know wherefore toshiba doesn't build the fanboost available to common users. the fans may be worn down quicker of course. what toshiba has done is to implement an extra quarantining throttling arrangement, limiting the multiplier to 18x (of 22x stock, 31x max turbo) and seriously degrading the processor effect Interahamw below the tdp of 45W until restart.
   this nagging limitation hind end still beryllium eliminated by throttlestop (Downloads), leaving it up to the processor internals to mold the power and multiplier factor capabilities. it seems like throttlestop is a mere requirement if you wanna run a laptop processor someplace near the rated operation. IT can also be exploited to limit the cpu-multipliers to bequeath enough power headroom for the integrated gpu. a multiplier in the range of 23x - 26x is good for gaming and other gpu-intensive tasks on my i7-2670qm processor.

   sorry wrong computer address.
   fanBOOST is now in stock at https://web.asuswebstorage.com/voyage/s/CABA2106684445629032B5F6CAC793EE4

   by the manner if you experience any troubles with the program you might have to reset the ec. to do that just close down, remove the powercord and the laptop shelling for a few minutes.

   in this case you cause to locate the proper register bytes for your specific framework.
   to do that open the embedded controller tab in rw and look for a byte that goes 01, 02, 03 in correspondance with the speed stairs of the auto rooter mode. that volition be the byte to set the speed mode - which on my machine is 0x55. then change the address in the sourcecode and hoard your own interlingual rendition with autoit v3.

   Hi - thanks for your work

   I want to lower sports fan upper for laptop ASUS U38n - about important spell information technology is in idle (it has an AMD APU integrated graphics, but ii fans to broad level in idle)
   I'm investigating what register direct in integrated controller using RW-everything, I can mange to change the speed betwixt dissimilar modes - however the setting reverts directly to the original setting within a couple of seconds (I think the regress is made my ACPI windows driver that continuously controls this ). Why is this not the case for you guys?

   Another option I'll approximate would be to qualify the BIOS, I'd downloaded AMI bios tool and investigated that for this ASUS mannikin U38n, these settings seems to be more deep hidden than for instance the Intel similar ASUS posture UX31A. I can only find the bios string, but not easy to figure away what to change...

   Hi snowstorm81

   I'm not acquainted with asus laptops, and i've concentrated on raising the fanspeed to obtain the full rated public presentation for for my processor.
   You've credibly already restrained out the following thread: HTTP://forum.notebookreview.com/asus/705656-rooter-control-asus-mature-ux31-ux31a-ux32a-ux32vd.html
   As far atomic number 3 i've read on asus laptops it is a affair of extracting, decompiling, modifying, recompiling and reinjecting the acpi-table into the registry.

   On my toshiba the acpi-table does not hold back anything about the fancontroller. I conceive it's because they wanted to make it harder to pull strings this piece of hardware.
   toshiba laptops has a driver called tvalz.sys that is competent to read the fanspeed and some powerreadings from the ec, but that is about all it ass do.

   Via rw it is withal viable to mesh the present state of the auto fan ascendence besides at the bottom level if I write 0x06 to the 0x55 ec-register byte.
   And it is possible to arranged a ineradicable low speed (2500 rpm) past piece of writing 0x17 or 0x15 (3050rpm). I didn't include it in my program because I didn't want people to fry their chips, symmetric though there is an home protection system in the processor just in case of overheat.
   So you better have a good hardwaremonitor the like hwinfo (HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Info and Analysis Tools) if you be after to construct it more dumb.

   If you have located the ripe register byte it's a matter of trial and error to identify the substantial values to write. There's no longer than 256 possibilities for that. Have a prissy day
   Alot of them will not do anything effective, surgery the ec wish revert them again, but as you can see from the ones I discovered there is not necessarily an understandable pattern in what values are good.

   I must advice you to only effort a modified bios as the very concluding hangout.
   It can lockup during flashing, departure you with a dead motherboard, as most laptop bios chips are not socketed.

   But it is funny to overcome the single limitations imposed away the oem's bios and bloatware.
   Cause when they advertise with a given processor, we don't like to see that it is for instance thermally pocket-size imputable an inadequate cooler.

   Luckiness.

   Hello,

   Does anyone know if it is possible to lock in a constant fan speed on a Toshiba Satellite In favor U500? I followed the book of instructions above and used RWEverything to muck around in the EC and key out the significant bytes -- they are 97 for first-string speeds and 98 for 'overuse' very smart speeds. When I manually variety the table of contents of these bytes in RWE the fan speeds up or slows down as expected, but no matter what I set either byte to, the system always changes the setting back to the default for the current temperature within seconds.

   My system overheats when playing newer games, so that I have to get on the lookout and quit playing every 20 transactions about and give the system a couple minutes to composed down, which needless to say is very annoying, non to mention running the ragged sharpness of 100°C privy't be good for the hardware. I reliable recompiling fanBOOST with my byte addresses (eg. "WEC16 0X98 0x01" to set byte 98 to 01, i.e. flat 1 overspeed), it compiled ok and runs normally, only fails to do anything with the fan f number, not justified for the deuce seconds that manual change in RWE whole works. I'm not a coder and this is kind of supra my unwavering (btw, what does the byte address format "0x-someting-something" mean? :-/ the bytes in RWE only have 2-digit addresses, 00 to FF... Wherefore always the "0x"?), so maybe I'm doing something evil. But if I understand information technology correctly, fanBOOST does not prevent the scheme from changing the Common Market stage setting back -- it needs a setting that bequeath stay locked in for good to work, so it's essentially just a GUI for what you can suffice manually in RWE conscionable as comfortably, right?

   So, presented that I tooshie't program, what can I coiffe to shut away in the speed setting I require permanently? (aside permanently, I mean bread and butter the system from ever-changing it arbitrarily; I would silent need to be able to shift information technology back down down manually, both to spare the hardware and to spare myself the noise)

   Thank you!

   I'm trying to determine the winnow EC bytes on my brand new Toshiba Z30T-A, but RWeverything half-hangs and eventually shows "FF" on all the bytes.
   I'm functional on the stock Windows 7 installation delivered connected the simple machine. Did you make any alterations to represent able to open the Europe windowpane? (in my case, other tabs seem to work better)

   Thanks
   Mike

9. The same goes for Pine Tree State , the temps climb very fast and in the end I end up getting a system shutdown. I request somebody to help oneself me regain the address for the X775 Qosmio fan. Because quitting very often is indeed frustrating.
