Aurora R11, CPU fan error after liquid cooling upgrade

Question

Hi all,

I have recently received my Aurora R11 (i7 10700, 3089, air cooled). I shortly decided the CPU was too hot and purchased the Corsair H60 liquid cooler to help.

Upon hooking everything up I am running into two problems.

When connecting everything correctly, top fan to top fan, front fan to front fan, and pump to pump fan (cpu fan left open) i am getting an error on boot for the cpu fan. This makes sense because there is not front fan. Bit terribly annoying, won't let me skip.

I tried switching the pump to cpu fan connection and this solved my error. But now when I go into AWCC to control fan speeds it reads the CPU fan speed at 90%. This is bizarre because this is connected to my pump. Will this cause problems for the pump?

My thermals seem to be the same in either situation (70c while gaming, was previously 90c without liquid cooling).

Dell's are setup to 'see' the proprietary fans and if not there it will give the Fan Failure notice and require pressing an F key to continue boot.  It will work OK just the notice.

For some reason it won't let me click the key to skip the fan testing and error. Not a major problem anyways its only when I boot up.

Any problem you could foresee with me switching the pump plug from pump fan to cpu fan? It gets rid of the error on boot but then AWCC tells me my cpu fan is running at 90% but this is in fact the liquid cooling. Just want to make sure AWCC doesn't try to modify the cooler like a fan and have something go wrong.

I don't have AWCC so don't know how it works.

Hey, I am having the exact issue and was wondering if this is what you resorted with. Did you just end up leaving the power cable in the cpu fan port instead of the pump fan? Is your AIO still working as normal but the AWCC is just telling you your fan speed is high?

bradles · Answer

Yup! Has all been working fine, no boot errors and AIO seems to be working fine.

AWCC will tell you CPU fan is running at 90% always but top fan and front fan display fine and are adjustable as you'd want.

Enjoy!

If you look closely that one isn’t a power cable. H60 powered by the sata cable and the one connected to cpu fan header only has one cable out and that’s the rev reading cable (please don’t judge my wording lol). So it should be fine. Also my awcc reading it’s 93%

OK, I posted the same in Aurora R11, VRM heatsink, H60 (2018) error 2000-0511 CPU FAN error on boot and received some good information there, and on a reddit post.

Correct config for the H60 (2018 model) is the single wire, 3pin connected to CPU FAN instead of pump.
Since power is supplied by SATA and not by a motherboard header, plugging the H60 pump tach wire into PUMP on the motherboard generates the error because it only "sees" a pump if it's drawing correct voltage from the motherboard.

With the pump tach connected to CPU FAN, AWCC will show CPU FAN at ~90% (depending on the version - apparently it may just show Running). It shows 90% because the OEM CPU fan runs around 4300 rpm. The H60 pump runs at around 4000 rpm. So a reading in AWCC of ~90% is actually correct.

I had the OEM cooler which came with the VRM heatsink but, thank you for the warning. The stock cooler was allowing for peaks of 99/100C. Now, it rarely goes over high 70s under load and at idle I was able to use better fan profiles for a quiter system at idle and also while gaming.

After your install did you have issues with the awcc temps for cpu front and top fans all reading the same? Only problem I am running into so far.

I had the same issue on my R11 that I purchased bare bones and stripped by a miner.

Installed is : I9 10850K with a H60 Corsair AIO and Noctua splitter feeding Corsair ML Pro 120mm non LED pro fan and the AIO supplied ML non Pro fan on the 3 pin side of the splitter.

Error was the same as recorded for every one else.

And this is with a VRM heat sink installed.

I switched to the CPU fan header and the error goes away.

Pump header even with the VRM cooler installed produces the cpu fan error.

@Frymaster @bradles @Kktse @Takeo64

Bios has been updated and also rolled back to try and gain the proper header usage.

I have ended up going fully left field and come up with my own solution as I wait for a replacement mother board to arrive. (Separate issue caused by tech not setting the color of the chassis and turning off 2 light zones)

My machine now has the following.

H60 connected to Pump Header.

Noctua fan splitter and fans as above.

VRM head sink.

Stock Air cooler fan now removed from its heat sink and magnetically mounted in to the small rectangular spot above the rear IO shield.

This is blowing air down on to the VRM cooler.

The pump is running at its default RPM via the sata power.

The Awcc I use to set the VRM cooling amount.

Top temp seen on the CPU is 62C

And that's playing a very Cpu stressful title with the fans hardly making a sound.

The Gpu below is also in the same temp range under load.

Weird I know.

Maybe the board coming from del with I hope a competent tech this time will be different.

AS the extra fan is not permanent so easy to throw back in the spares box.
