Problem With Corsair H100i V2

Yeah thats a bad pump then.. Sorry dude i hate when stuff fails..

Posted

So my professor and I built my PC around May 2016 and I've been using it since. Didn't ran into any problems and assumed everything's okay until now. When I booted it up earlier this morning, instead of booting up Windows, it instead went into the POST screen which didn't happen before. The CPU LED on the motherboard is lit red. On the POST screen, there's an error saying "CPU Fan speed error detected." (images below). After a while, another error comes up, "CPU Over Temperature Error!" When I ran the BIOS setup, the CPU temps were at 88°C idle and the FAN Profile doesn't detect the CPU Fan (even though the cooler is connected to the CPU_FAN header). I've read some forums online and some were saying that ASUS mobos are faulty sometimes and may display really high temps and RealTemp says otherwise. I then set the CPU Temp and Fan Speed Monitoring to "Ignore" so I can reach the Windows boot screen. When Windows had booted up, I ran RealTemp and the temps are at 90°C to 100°C idle.

 

I'm guessing the problem could be A) The CPU cooler is faulty, B) the cooler isn't mounted properly, C) Bad thermal compound, D) the CPU itself is faulty (which I hopefully not)

 

Sys:

Intel Core i7-6700K
Corsair H100i V2
ASUS Z170-A
Corsair RM850x

 

Note: Never OC'ed the CPU and is running at stock speeds; the radiator fans are in a push configuration upwards; using the pre-applied thermal compound

Any help/suggestions?

Did you check to make sure the fan plug for the water pump is plugged in all the way? and that the cooler fans are also?

The fan header on the motherboard needs to be disabled so that the pump runs at 100% at full 12v.

Newer motherboards have a "pump" fan header which is always at 100%.

You need to make sure that the fan header the H100i is plugged into is set to full voltage in the UEFI.

You can also use a molex to 3 pin fan adapter if you don't want to deal with UEFI/BIOS.

I plugged the CPU block plug into the W_PUMP header on the board yet the CPU temps are still at 89°C (BIOS) and yeah, the plugs are inserted properly.

I would send that cooler back. Id say you have a bad pump.. I also wouldnt use it until you do. with those temps you are bound to start degradation on your cpu.

The BIOS shows "N/A" on the water pump indicating that it doesn't detect the cooler even though the CPU block is connected to the W_PUMP header, just like the CPU fan header.

My professor said the same. Told me to send it back and have it replaced or find a different cooler. Though I'll wait for further suggestions from other users for now

As long as you're sure you plugged it in right, then RMA it or try testing it on another motherboard or a molex to 3 pin fan adapter.

If it doesn't work on the molex adapter then it is 100% dead.

have you tried connecting it into cpu 1??n I have always used that channel and set fan curves

I've tested it on every fan header and same results. Every time I boot it up, the CPU temps always rise up to 89°C gradually

Man, this sucks. I guess I won't be able to use my PC until a new cooler is installed. Really bad timing. I have finals 3 days away and still have a lot of school projects to do.

 

Anyways, thanks for all the help, guys. This forum is indeed helpful. It's my first time starting a topic here...

Are you running AIDA64, HWinfo or another monitoring software that is monitoring the AIO sensors at the same time as Link? Look at my signature for a possible fix. If that doesn't fix it the pump is probably dead and you likely need to RMA.

Having issues with a Corsair AIO? Possible fix here:

Spoiler

Are you getting weird fan behavior, speed fluctuations, and/or other issues with Link?

Are you running AIDA64, HWinfo, CAM, or HWmonitor? (ASUS suite & other monitoring software often have the same issue.)

Corsair Link has problems with some monitoring software so you may have to change some settings to get them to work smoothly.

-For AIDA64: First make sure you have the newest update installed, then, go to Preferences>Stability and make sure the "Corsair Link sensor support" box is checked and make sure the "Asetek LC sensor support" box is UNchecked.

-For HWinfo: manually disable all monitoring of the AIO sensors/components.

-For others: Disable any monitoring of Corsair AIO sensors.

That should fix the fan issue for some Corsair AIOs (H80i GT/v2, H110i GTX/H115i, H100i GTX and others made by Asetek). The problem is bad coding in Link that fights for AIO control with other programs. You can test if this worked by setting the fan speed in Link to 100%, if it doesn't fluctuate you are set and can change the curve to whatever. If that doesn't work or you're still having other issues then you probably still have a monitoring software interfering with the AIO/Link communications, find what it is and disable it.

I tried both the AIDA64 and the HWiNFO solution but the CPU is still hot and toasty. RealTemp and Link are showing 89°C - 100°C on each core. Likely gonna RMA

Since I'm gonna RMA this cooler, is it safe to leave the CPU exposed or there should be at least a temporary cooler mounted while the H100i V2 is undergoing RMA?

There needs to be a cooler on it.

You also need to clean off the thermal paste and reapply new paste every time you change cooler.
