URL that I gave.Â* Where do YOU see any skins presented?

Yes you seem to have an old page, I should have included the proper one.

You need the version 4.9.5.25 which is the one I have, it is the latest
one on this page.

http://www.corsair.com/en-us/downloads

Select category, Corsair Link, than 4.9.5.25
Then you will find all the settings etc


Ah, so Corsair won't show be the proper (latest version) screenshots.
Instead I would have to *install* the program before I can see what it
looks like.Â* Thanks for the info but no thanks.Â* I don't install
software just to see what it might look like.Â* I do that ahead of time
as part of researching the software.Â* Corsair really needs to update the
product page to show screenshots for their latest version.

I did a Google Images search on "corsair link" and found some users had
posted screenshots showing a different skin than the one Corsair shows
on their site, like:

http://i.imgur.com/T8DNKnW.png

So they have a less busy page.Â* Hopefully the user can turn off the
blaring white-on-bright-red section titles but it's better than the
background showing the inside of a computer case.


I agree, that UI with the computer case isn't to my liking either.

I've already posted some of this once, but it seems to have got lost, so
here goes again. I installed that 4.9.5.25 (the latest on the page), but
when run, I just got a title bar which disappeared. So I uninstalled it
with prejudice, and tried the oldest on the page (4.7.0.77). That
installed, but when run, it told me there was a later one, did I want it
(it obviously 'phoned home to ask, without asking permission); I said
yes, and it got it and ran.

Since then, my machine has been running hot. At one point I fired up
SpeedFan (in monitoring mode only!), and it was over 100 (C)! I've
quickly plugged in the old USB fan tray I'd been using with my XP
machine, and things are more manageable now (below 60C). I have in the
meantime run Toshiba's own test of the cooling system (takes about 23
minutes), and that said all is well (I heard it run the fan up and
down). Since overheating was what killed my XP machine, _and_ the fan on
this one used to cut in quite audibly for even a slight rise, I'm
decidedly unimpressed with Corsair Link: it seems to me that it has
set/changed some control, even though I only intended to use it as a
monitor; any suggestions to fix what it broke welcomed. I'm certainly
going to uninstall it again: the only reason I haven't is in case it
needs to be there to do any fix.

I thought I'd give it one more chance, so clicked on the start menu
shortcut it installed. It now comes up with (ding) a window saying
"Problem with Shortcut\The parameter is incorrect." So I look at the
properties of the shortcut: it's one of those with the Target box greyed
out and blanked - the sort of thing Microsoft do for Internet Explorer
and some Office things. Fortunately it has something in the "Start in:"
box ("C:\Program Files\CorsairLink4\"), so I look there. The .exe -
which is 26,479 KB! - just for a fan monitor?!? - is indeed 4.9.5.25.
When I try to run it directly, it's back to being the
title-bar-only-and-that-briefly behaviour, although it does add a bar to
the taskbar and an icon to the tray. Left or right clicking on the tray
icon makes nothing happen. I can kill (close) it by right-clicking the
taskbar bar. (There was one task in Task bar, which disappeared.)

So - Corsair Link:
o installs "funny" shortcuts.
o is huge.
o won't run for me more than once (as far as me actually seeing the UI,
that is; _something_ runs when I run it).
o has a pretty horrible UI. (_Might_ be possible to change to a plain
one as described in this thread _if_ the UI would actually come up!)
o _seems_ to have done something to my fan control.

(The one time I did actually see the UI, there seemed to be three modes,
one of which _had_ to be chosen - I think one of them was called
something like "performance". There did _not_ seem to be a "monitor
only" option.)

Thoughts? I do have a full image from only the other day, as it happens,
but I'd rather not go to that if I don't have to. (I may also have
System Restore points.)


Sorry to hear of all your troubles, I would also uninstall it if it gave
me such a hard time.
I am running an i7950 CPU system and an Asus X58 Sbertooth MB.
I left mine running in the performance mode to be sure it used all fans
and everything is good, So I ran it in balanced and quite mode and all
fans and temps stayed the same.
Is yours in Performance mode?
Quite mode may slow down or stop fans, But mine did not
I have one bogus temp on mine always shows 64 deg C both in Corsair and
Speedfan,
some kind of sensor not present thing.
Can't think of anything else to try except uninstall if its not
compatible wit your system.

Those were indeed the three modes - balanced, quiet, and performance. I
chose performance as I thought that was likely to do the best cooling;
my point was that there didn't seem to be a way to tell it to revert to
whatever had been in place before I installed/ran it. And just stopping
it, or even uninstalling it, seemed not to revert things. I couldn't
tell you what mode it was in now, as I couldn't get it to open up the

Well, I tried uninstalling, without success. However, I have now done a
system restore to just before I installed it the first time, and things
seem - touch wood! - to be good: the cores are below 50C, and I've heard
the fan occasionally.

One attribute I've seen of some software fan controllers is they can
only manage 4-pin fans; i.e., those that are PWM (pulse-width modulated
- ground, +12V, RPM sense, speed control). Speedfan, on the other hand,
can change the duty cycle of the voltage to the fan which emulates PWM.
Instead of regulating the speed control of the fan, it regulates the
average voltage to the fan.

https://en.wikipedia.org/wiki/Comput...ontrol#PWM-FAN

Check inside to see if your CPU and case fans are 3- or 4-pin.

The PC that I salvaged had a defective mobo in that the PWM control for
the CPU fan didn't work. The BIOS fan control couldn't regulate the CPU
fan but I could use Speedfan to duty-cycle voltage regulate the CPU fan.
If it weren't for Speedfan, I'd have been stuck with a very noisy PC.

Because the fan is not getting constant voltage and using the control
line to change RPM, you could lower the average voltage too low (or make
the off cycle too long). The result is burning out the fan or it won't
start spinning. While I could get Speedfan to lower the CPU fan down to
30% duty cycle (30% on, 70% off) with the fan reliably spinning up and
down to regulate its RPM, I set it to 50%. I could barely detect the
increase in noise from 30% to 50% but I felt better having the fan
experience a higher average voltage.

To get Speedfan to *not* use hardware PWM control for the CPU fan, I had
to set an override. Under the Advanced tab, I selected the "IT8720F at
$A0 on ISA". As I recall, I had to change PWM1 Mode and PWM2 mode from
On/Off (using hardware PWM) to "software controlled"; i.e., Speedfan
would regulate the fan's duty cycle instead of using the PWM control to
tell the fan to change RPM. I can't be sure that's how I got Speedfan
to use duty cycling instead PWM control on the CPU fan because it's been
6 years since I salvaged the circa 2009 Acer PC. I had planned on using
the BIOS temperature controls but they wouldn't work (since they assumed
they would regulate RPM using PWM).

I tried to look at Corsair's knowledgebase to see if their Link tool
worked with both 3- and 4-pin fans or only with 4-pin fans. They wanted
me to login to an account. Not going to happen. Their FAQs didn't have
anything about their Link software regarding what type of fans their
software can control.

From past articles for Speedfan, speed control can also be screwed up if
the wrong table is used for the fan controller. Could be the table that
Speedfan used is wrong. Could be the table burned into the firmware for
the controller is wrong.

After uninstalling Corsair's Link (and doing all the remnant file and
registry cleanup) and rebooting, were the fan speeds still uncontrolled?
Was Speedfan still installed and it couldn't control the fans anymore?
I'd make sure everything of Link got removed, uninstall Speedfan (and do
the remnant cleanup), and reinstall Speedfan to see if it regained fan
speed control.

That's what I'm doing. I really only installed it because someone here
said it had a nice interface for monitoring, I didn't want any of its
controlling aspects. (I didn't like the default one - with pictures of
computer cases - but apparently there are plain ones, but I couldn't get
it to give me the UI enough times to play.)

seems OK so I will leave it in, If it gives me any trouble I will toss
it.

Rene

I'm glad it works for you! (Though I still think it's far too big for
what it does.)

This is a laptop, with I think only the one fan. I'm not at the stage
where I want to open this one up completely yet; the XP machine I used
to have was I think only a three-wire fan.

The PC that I salvaged had a defective mobo in that the PWM control for
the CPU fan didn't work. The BIOS fan control couldn't regulate the CPU
fan but I could use Speedfan to duty-cycle voltage regulate the CPU fan.
If it weren't for Speedfan, I'd have been stuck with a very noisy PC.


(And one which wouldn't have lasted as long, probably.) Useful to know
SpeedFan can rescue equipment in that way.

Because the fan is not getting constant voltage and using the control
line to change RPM, you could lower the average voltage too low (or make
the off cycle too long). The result is burning out the fan or it won't

Yes, stalling them's not a good idea.

I've gone back using a system restore, and things _seem_ to be OK. I
feel inclined to leave what's working alone now! I don't know if the
built-in control is entirely hardware, or uses _some_ softwa it
certainly seems to crank up the fan if the processor load (as shown by
task manager) gets much off the bottom, but that _could_ be a hardware
system responding quickly; I know processors do heat up quickly. All the
time, I've had SpeedFan (4.52) installed purely as a monitor: and, it
doesn't even seem to be able to monitor fan speed, only four
temperatures (called HD0, Temp1, Core 0, and Core 1), as well as four
bars for the CPU Usage. Here's what it says in its little window:

Win9x:NO 64Bit:NO GiveIO:NO SpeedFan:YES
I/O properly initialized
Linked ISA BUS at $0290
Scanning ISA BUS at $0290...
Found TOSHIBA fan driver
Found HGST HTS541010B7E610 (1000.2GB)
Found ACPI temperature
Found Intel(R) Core(TM) i3 CPU M 380 @ 2.53GHz
End of detection
Loaded 4 events

I'm assuming the HD is monitored via SMART. Under the Info tab, it says
No known chipset detected; under Charts, it gives me the four choices
under temperatures, and nothing under fan speeds or voltages. Under
Configure, it confirms (?) that HD0 is via SMART, the other three being
via ISA.

SMART attribute 194 reports temperature, so that's how Speedfan gets it
from the HDD/SDD.

The fans must report their speed using SMBus. Well, Speedfan queries
the devices that will report on the SMBus.

https://en.wikipedia.org/wiki/System_Management_Bus

On the Info tab, there is a "Find SMBus devices" button. Does it find
anything? I suspect the laptop came with bundled software. I remember
having to spend days researching what all the software was for that was
getting loaded in Windows startup on a Dell PC. I could get rid of a
lot of the fluff but some were essential. Could be Toshiba is using
their own software to control fan speed and that interferes with
Speedfan querying the devices. Only one fan control program should be
managing the fan speeds.

Speedfan would report what it found on the SMBus but not in your case.
There is no mention of "Scanning SMBus at address" or of it finding a
controller (for the fan).

Mobile processors are made to be low-power (reduced heat) but need extra
cooling when there is any load on them. All the laptops that I've used
have cycled through low and high fan speeds repetively while I used
them. Different fan speed controllers have different hysteresis: the
rate at which they will change fan speed based on the rate of
temperature change. Speedfan might not be a good choice for a mobile
processor. Fan speed has to change quickly and Speedfan might think it
has more time (with a larger heatsink for a desktop) to change fan
speed. I didn't find a hysteresis setting in Speedfan but then I don't
know if that's part of the info table in the controller that Speedfan
will read. When I go under Speedfan's Advanced tab and select the
controller chip for the fans, none of the attributes is for hysteresis.

As I mentioned for my salvaged mobo, I had to change Speedfan's default
configuration to "software controlled" for the controller chip. Maybe
you have to do that, too. If that works, make sure to enable the
"remember it" setting; else, when Speedfan next loads, it will use the
default because the setting doesn't stick unless you say so. For me,
"software controlled" was an available selection and worked. For
others, like http://tinyurl.com/ydatp8oa, they may have to deselect one
of the other control methods.

In Speedfan under its Fan Control tab, did you enable Advanced mode
(where you can name a profile, select a fan, and then determine its
speed curve)? http://tinyurl.com/ybwpo3j5 is someone else's example. I
don't bother with this level of control. If you are using advanced
mode, could be there's nothing defined for the speed gradients or
they're wrong from what you expect or want.

If I tick the Advanced box in that tab, a blank window comes up, with
Add and Remove tabs; if I click Add, it prompts for a name. If I type
test, it adds it to the empty box, but nothing else appears - no
controllers or anything. I Cancelled my way out of there. The system
seems to be working - all three are in the high fifties, and the fan
seems to be coming on and going off as required, which I don't _think_
it was when Corsair Link had anything to do with it. I'm not going to
mess with it! (Well, other than keeping SpeedFan _purely as a monitor_.)

The scan is very quick. Looks like Speedfan cannot find anything that
responds on the SMBus (assuming your laptop has that bus). There must
be an SM Bus Controller or System Management Controller chipset on the
mobo to support SMBus. The device must install an SMBus driver so it
can be queried on state of the device and to ask it to retrieve info
from the device.

https://www.intel.com/content/www/us...-software.html
https://communities.intel.com/thread/110358

The chipset driver package from the mobo maker (or laptop maker, in your
case) must include an SMBus driver to perform the management. That is,
you need to install the chipset driver package (suite of drivers) so
Windows knows how to communicate with THAT hardware. When you go into
Device Manager (devmgmt.msc), do you see an SMBus Controller device? As
I recall, UMBus (User-Mode Bus enumerator) replaced SMBus as of Windows
Vista. It enumerates the devices found (that report themselves) on the
user-mode busses.

Umbus.sys is a Windows driver. A driver is a small software program
that allows your computer to communicate with hardware or connected
devices. This means that a driver has direct access to the internals
of the operating system, hardware etc.

On my Windows 7 x64 setup, no "SMBus Controller" is listed but there are
a "UMBus Root Bus Enumerator" and two "UMBus Enumerator".

If I tick the Advanced box in that tab, a blank window comes up, with
Add and Remove tabs; if I click Add, it prompts for a name. If I type
test, it adds it to the empty box, but nothing else appears - no
controllers or anything.


After adding the "test" profile, did you click on that profile to select
it? Only when it is selected will the relevant fields show up below,
like Controller Speed (if you want to pick a method), Method, and
Temperatures (where you define setpoints for temperatures and fan speed
at those temperatures).

Since Speedfan found no fan devices on the SMBus/UMbus (assuming there
are any and that mobo's chipset drivers have the SMbus/UMbus drivers)
then it's not much of a surprise that this section remained blank. Your
hardware and driver setup isn't reporting anything for Speedfan to find.

nothing appears in the window, and the button is still called "Start

The scan is very quick. Looks like Speedfan cannot find anything that
responds on the SMBus (assuming your laptop has that bus). There must
be an SM Bus Controller or System Management Controller chipset on the

The bottom of my Device Manager goes: Processors, Security Devices,
Sound, video and game controllers, System devices, Universal Serial Bus
controllers. No sign of SMB or UMB.

It comes up with: a "Controlled speed" tickbox; a dropdown that only has
"Pwm1 - Pwm1 from Toshiba @ $0000 on ISA; a "Method" dropdown containing
the choice of SUM of speeds and MAX of speeds; and a blank box labelled
Temperatures, with Add and Remove buttons below. Clicking on Add brings
up the list of four temp. sensors. Adding one of those then clicking on
it, brings up a graph, with adjustable bottom and top limits, and a
hysteresis up/down one.

Looks like I _could_ set _something_ up if I wanted.

I'll leave it be! But thanks for the tips; I'll know in future about
SpeedFan.
