Thank you very much. First important question, can I run AI Suite and Link 4 at the same time without ending up in an WHEA Error? :) If yes, thank you very much indeed!

cooler H100i
windows 10 pro 64 bits build 11102. (insider)

I installed that version and work ok. I had to change the fan and installed the Noctua NF-F12 PWM 120MM Ultra Quiet Cooling Fan 300-1500RPM 93.1M3/H 22.4DBA 4-PIN PWM
At boot I receive very fast message then the corsair link windows appeared and work ok. Is there a fan manufacturer check at start ?

I've installed it and it's working perfect

Just a question. why the CPU and Graphics Fan doesn't showed on configure menu?

I wonder if Corsair knows that there are no links on the forums pointing back to the download page for Corsair Link v4?

WOW!!! Talk about a huge step backwards!!

Whose bright idea was it to remove the ability to punch in numbers for the fan speeds and force users to plot points on a graph. Do they know how much of a PITA it is to try and configure a push pull setup when both fans must be the same speed. Before it was as easy as punching in temperature and what speed I want the fans at that temperature, now its a guestimate as it is very difficult to get a even value on the graph.

Gone is the ability to resize the window like a normal window. You have to be an eagle eye to notice the lower right hand corner

For some odd reason my H80i is showing a fan connected to port 4 when I only have fans connected to ports 1 and 2.

I have the same problem. My AX1500i is also not detected. It is connected by usb directly.

Also the fans/rpm of my 3 980tis are no longer showing.

Oops CL4 Issus on my ASRock X79 Champion W7 x64 Build 7601 system

I am sorry to tell you that your suspicions are incorrect. As of 09-Feb-2016 since the release of CL4 of 26-Jan-2016 there has not been much if any help from Corsair staff on this forum or comments on the issues raised. On the 11-Feb-2016 I spotted the 4 posts from Corsair Chris which is rather less then there needs to be and says a lot about Corsairs commitment to CL4.
  1. There don't seem to be any detailed release notes. What is their URL please?
  2. Not supporting the old Commander is a strange decision given it takes SIV < 40 lines of C to support it.
  3. When started it CL4 takes 20 -> 30 seconds before all the hardware is reported on the home screen. This is far longer than it should be. SIV took 1.67 seconds so why does CL4 take over 10 times as long? CL4 log attached.
  4. When I first ran CL4 it set default values in my hardware rather then reading the current settings as CL3 does. This is a PITA as it meant I needed to set them all manually. Is this a Bug or a Feature please?
  5. The Windows + CL4 version information should be displayed. I feel either on the menu line right or bottom right of the screen would be good. I feel Windows 7 x64 Build 7601 + CL would be good. The build is needed for W10 as TH1, TH2 and RS1 are very different. Quite often members post CL4 screen shots and I have to almost guess which system they are from.
  6. When I switch from [Home] to [Configure] it takes about 15 seconds when I have all my CL hardware connected. This is far longer than is acceptable.
  7. I suspect using TCP as the transport between the service and GUI could be a factor in this and feel this was rather a poor design decision. I suspect there others.
  8. When the CL4 screen is moved to the left of the main desktop it instantly jumps back to the main desktop which is at 0,0. Moving it to the right is OK. This is a regression from CL3.
  9. The service.log log file seems to be always created and I can't find out how to disable this. It could also end up being rather large, mine was 84MB when I deleted it and I suspect those who run CL4 24/7 may end up with several GB.
  10. If I close down and restart CL4 the initial screen size is changed to the small default size when I expected it to be as I had set it which was the case with CL3. It also is on my default screen rather than where I last positioned it.
  11. When I close down CL the cpuz138 service is not stopped and deleted. This is a regression from CL3. Given I have reported this before how come it was not picked up in regression testing (it is considered good coding practice, when a bug is located and fixed, to record a test that exposes the bug and re-run that test regularly after subsequent changes to the program)?
  12. hydros7289.inf should be fixed such that H80iGT + H100iGTX + H110iGTX as reported as such by Device Manager to bring them into line with the HydroSeries H115i, etc.. as this would avoid confusion such as
  13. hydros7289.inf should be changed for the H80iGT + H100iGTX to match the USB REV so it does not get used for the old Link Commander. See
  14. hydros7289.inf should be updated to support the Corsair Link™ USB Dongles so only one driver is needed. Both siusbxp.inf and hydros7289.inf specify the same SIUSBXP service, so having both is silly.
  15. CL4 Causes High DPC Latencies, see
  16. On [Home] all the same type of devices have the same name, but on [Configure] they have #1, #2, ... numbers. I feel there should be numbers on [Home] so it's clear which is which.
  17. On the Devices panel all 4 x CLCC have exactly the same description, so it's tricky to know which is which. Same for the 2 x RM PSUs + 3 x Lighting Nodes and I suspect every other device type.
  18. The two Corsair RM-Series C-Link Adapter should be RM 1 and RM 2.
  19. The Temp, Fans and LEDs headings on the CLCC + Cooling Node should be removed and there should just be a heading of CM 1, CM 2, ... CN 1. This will make them the same as the H100i so all the items are consistent.
  20. The three Lighting Nodes should be LN 1, LN 2 and LN 3.
  21. CL4 reports both my AX1500i + AX760i at the same time, though I can't seem to get detailed information for both at the same time. The Power and Efficiency should be on the Home screen, better still I should be able to select what is on the Home screen.
  22. CL4 should use Temp rather than Temperature as is the case everywhere else.
  23. CL4 will report my AX760i when I USB connect it, but not my AX1500i. I assume the CL4 code only checks for a PnP ID of VID_1B1C&PID_1C00 when it also need to check for VID_1B1C&PID_1C02 and maybe VID_1B1C&PID_1C01.
  24. CL4 incorrectly reports my BLT4G3D1869DT2TXRG PC3-14900 DIMMs as PC3-10700.
  25. Having the Crucial Technology heading eight times is pointless. It should only be there once or when it changes as is the case on my Dell 490. On my HP DL580 G5 it has 4 x Micron Technology PC2-5300 headings and fails to mention Samsung and Hyundai at all. Having thought about this I feel CL4 should just have a heading of PCn-nnnn and default names of Temp 1 to Temp nnn as if a user wishes to get maker information they would do better to use a program designed to provide this. The cute option would be to have a Tool Tip similar to the one I have in SIV.
  26. CL4 is missing the Dell 490 section and the motherboard temperatures + fans + VCPU information.
  27. Why is CL4 reporting the WDC WD1600JS-00NCB1 temperature twice? I feel this is either poor ergonomics or a bug.
  28. CL4 is reporting Motherboard when it should be HP DL580 G5 and all the SMSC SCH4307 sensor information is missing.
  29. The per X7460 % CPU used totals are incorrect by at lest an order of magnitude. From Task Manager it's obvious that it can't be 30% let alone 68%. I also noted that the % only changes for the first Xeon. Note the system has 3 CPU Groups with 8 CPUs in each Group.
  30. The Xeon X7460 core temperatures are correct for the first 8 cores and the remaining 16 are all reported as 36.0°C which is clearly incorrect.
  31. Having the Cores ordered 1 10 11 12 2 3 4 5 6 7 8 9 is silly and different to how Microsoft order things on Windows 10. There is also the same silly ordering on the AX1500i PCIe outputs.
  32. The package temperature for my Xeon E5-2696 v2 (Ivy Bridge-EP) is incorrect , see
  33. None of my CSMI RAID or USB attached disks are reported. The CMSI protocol is well defined and for CL4 to fail to support it is rather poor.
  34. Only 4 of my 6 motherboard fans are reported. I have been waiting 14 months for this to be fixed.
  35. My H80 is reported as a Cooling Node, same for the H100.
  36. The Devices panel can't be resized and I suspect there are many others. Any panel with a scroll bar should be resizable.
  37. I can't seem to set a PWM % of < 40 %. How do I enable "advanced" mode so I can do this?
  38. I can't find how to configure a Custom Curve to use multiple temperatures. Is this possible?
  39. I can't find how to setup a Custom Curve for my AX1500i or AX760i PSU Fans. Is this possible?
  40. I can't find how to setup a Custom Curve for my H80iGT Pump. Is this possible?
  41. I can't find how to select the temperature source for my H80iGT Fan. Is it still limited to just the H80iGT Cooler Temperature?
  42. I can't find out how to update CoolIT firmware. Is this possible?
  43. I can't find any CLCC or any other firmware, was expecting (wishfully hoping for) a new version that fixed the long standing bugs and added support for 0 % PWM to stop the fan.
  44. My RM PSUs are not available on [Configure]
  45. My Motherboard Fans are not available on [Configure]
  46. My GTX 980 Fans are not available on [Configure]
  47. The Total % is not available on [Configure]
  48. Only my AX1500i + AX760i PSU Temp and fan speed are available on [Configure]. All the PSU information should be, epically so for the Power and Efficiency.
  49. On [Configure] I should be able to dock items and then move them all as a group as having to move each item of a CLCC one at a time is a PITA.
  50. Setting up push-pull cooler fans to use the same Custom Curve is at best tricky. There should be a facility to group fans together then use the same CC and also to clone an existing CC to a different fan/pump.
  51. When I exit CL4 it sometimes fails to release a semaphore. This is caused by both poor code and design as it should use a Mutex rather than a Semaphore because a Mutex would be implicitly released on thread exit by the Windows thread cleanup.
  52. Worst of all CL4 does not correctly implement Global\Access_CorsairLink named mutex support

CL is a future version so why has this not been addressed?

OK, I am being rigorous, but I would expect a "solid team" to be equally if not more rigorous. The MB and GPU fans not being available on [Configure] is one of the worst oversights I have ever come across . I did not really try to find issues, but when I noted them I checked what happened on my test systems that I use to test SIV and found yet more issues. Even I was surprised with the number of issues I found .
I currently suspect CL4 had to be released to support the H115i + H100iV2 + H80iV2 and is not really ready for general use. Given it look me maybe 30 minutes to add support to SIV for these I suspect a new CL 3.2 release would have been wise.

Dustin, I gather you have moved on and are now working in Product Management. Good luck in your new role and welcome to Corsair Chris who now has your previous role.


Most of the CL hardware is sitting on my desk and I use it mainly to test SIV. I only ran CL4 so I could update SIV to detect it and not report CL hardware if it is active. I was also hoping that it came with fixed CLCC firmware.

Why doesn't the graph stay open when the main window is minimized I mean really only way to keep the graph open is with the main window open. Why is corsair so terrible at making software? I think this is the final straw that will send me to nzxt grid+ and hue+ as both are superior products compared to corsairs crap.

Sigh.. CL4 Issues on my ASUS P6X58D Premium W10 x64 Build 11102 system

I found it hard to believe how bad CL4 was on my W7 system, so I tried a W10 system and it has many of the same issues.
  1. CL4 wants to reboot the system for no good reason just because it found a H110iGT. As I specified in this is not needed. While CL was prompting I started up SIV 5.06 which happily reported the H110iGT as you can see.
  2. Testing on W10 x64 RS1 Build 14251 SIV was happily reporting my H110iGT with the initial Device Parameters. I then exited SIV, ran CL4 and it prompted for a reboot. It also zeroed AllowIdleIrpInD3 + DeviceSelectiveSuspended when this is not needed.
  3. If the CPU does not report the Package Temperature the average core temperature for the package should be reported. On a Dual Xeon system there will be two of these.
  4. CL4 incorrectly reports my BL25664FN1608.16FF PC3-12800 DIMMs as PC3-10700.
  5. None of my CSMI RAID or USB attached disks are reported.
  6. The GT 520 Fan PWM % should be reported as it does not report the RPM
  7. My Motherboard Fans are not available on [Configure]
  8. My GTX 680 Fans are not available on [Configure]
  9. The Total % is not available on [Configure]

Default CL service not running

Corsair Link won't detect any hardware in my machine, not even motherboard.

I notice a service called CorsairLink4 isn't running. Attempting to run it fails and puts these in the Windows Event Log. CL3 found my stuff. SIV shows Link hardware connected and can control it. SIV is not running when I'm attempting to use CL4. I have tried rebooting many times, as well as reinstalling many times.

Link hardware I have: Corsair H100i, Corsair Link Commander Mini, Corsair AX1200i

Found the culprit: It's conflicting software. I'll be looking at what exact software it was as I stopped like 10 at once. I think it's EVGA Precision X, but haven't been able to confirm yet.

Ehm guys? I love this new design, BUT, It's Celsius, not Celcius. :S
Besides that, working great with my H100i.

One question tho, when I change the profile type, the LED color changes also, is this on purpose?

Does anyone know how to create groups? The feature seems to be missing since CL3. I wanted to link my fan speeds to my CPU Package, not cooler temp.
