Aurora R8, 3rd party cooler, fan speed error
HI all i could not find any solution online at all so i decided to give this forum a shot, i received my aurora 8 with a stock fan cooler and i decided to upgrade it to liquid cooling, so i installed a EVGA CLC 120 CL11. I have the pump plugged into the pump header and the cooling fan into top fan header I am also running the latest Bios Version 1.0.0 but when i boot, i get the dell support assist with : Error Code: 2000-0512 Fan-The (CPU) fan is running faster then expected I then have to wait until i can continue, usually 4 minutes because it won't let me press ESC, then i can boot into windows, my temps are perfect at 35 on idle on a i7-8700 none K I tried re-updating the BIOS and nothing i also cleared CMOS and still same error on boot Someone on here installed the same cooler i purchased on a R7 and worked like a charm plugged it into same header connectors, but the R7 has a different Bios, so am thinking it does not give that error and the R8 does because of the new Bios thus making the dell assist error The only thing i can think of, is the stock cooler has a jumper cable going from pin 4 (control) to pin 1 (ground) so i Ordered a 3-Pin (Socket) to 4-Pin PWM (Plug) and am going to jump pin 4 to pin 1 and my guess is that will solve the fan speed error. I would like feedback on this please , i hate to wait 4 minutes every time i have to boot and get the annoying dell support assist.

OK guys so i jumped the pump header and now i get a top fan failed to respond correctly error message so the pump fan error message is gone but now stuck with this fan message now , my guess is the fan has a sensor or it spins at certain RPM that the BIOS recognizes only with stock dell cooling, so if i could find just the fan would be soo nice but i cant find it by itself, if anyone has one let me know please thanks, at least i don't have to buy the whole pump, but i doubt i could find the fan alone.
thanks guys guess for now will just have to wait the 4 minutes to boot up unable to hit ESC
i think Dell has is slaved to their hardware :)
error code : 2000-0511
Any suggestions much appreciated :)

The stock AIO fan Dell uses is a 120x37mm Nidec 35502. The part number is B35502-35DEL7 and PP749-A02.
The BIOS does pre-boot checks to verify the fan is actually working. For an AIO, the fan should be connected to the TOP FAN header on the motherboard, and the cold plate with pump connected to the PUMP_FAN header.
Certain aftermarket fans will cause an ePSA boot error because for some reason, the fan won't actually spin until Windows start and AWCC gets loaded into memory. I've only found 1 aftermarket fan to work correctly and that is the Corsair ML120 Pro. Even the non-pro ML120 causes boot errors.
P.S. what I mean by work correctly is that the ML120 Pro spins on power on whereas other fans do not. ePSA detects the fan spinning thus it won't trigger a diagnostic event. However, if you specifically test that fan, it will also fail as it cannot meet the target 3700 RPM ePSA calls for. Only the Nidec fan will pass both ePSA boot and extended diagnostic testing. I swapped mine to an ML120 Pro after having tried various Noctua and other Corsair fans after my OEM Nidec started ticking due to bad bearings. Also, the Nidec when it ramps up becomes very loud whereas the Corsair still remains quiet.

Amstel thx for that info, now if you can tell me if the procedure for changing the fan on the R8 is removing the top of the case to have access to the radiator?

Yes, you'll need to remove both side panels and the top plastic panel which is clipped on. Once the top panel is removed, the radiator can be taken out of the case by loosening the 4 screws securing the radiator to the housing. Check the R7 or R8 service manual on how to remove specific parts for more detailed info.

Hey so am going to order the Corsair ML120 Pro. So just to be on same page this is for the R8 that it works on and you do have the R8 right

Reason is why I saw others using AIO coolers even the same I have with no errors , so I was thinking it was because the BIOS revision is different then the R7 and so letting it work on the r7 and not the R8, so your saying it also gives same error on both bios

I have an R7. But the motherboard, case, and OEM radiator are for all intents and purposes, identical.

Sorry to hear that... and that is unfortunate news for R8 owners wanting to upgrade their fans.

Negative I just went and purchased the ML120 Pro at Best buy and still get the error on boot so if you don't have a R8 the. On your R7 it will work because the BIOS in different then the R8 it's what I was suspecting so seems like Dell has changed the Fan on their new R8 line to go with the new Bios tightening their proprietary

Yes, the second error you're seeing now is the exact same one I had when I replaced the Nidec fan. I first tried a Noctua AF-12, then a Noctua iPPC-3000, then a Corsair ML120. All three gave the same error because the fan wasn't spinning up on power on. Only the ML120 Pro spun up on power on, thus bypassing ePSA diagnostics automatically.

Since you now have an ML120 Pro laying around, you could also test it by replacing the front fan. See if you get the same error code there. If you do, then you're most likely right and Dell really did something to the UEFI to make it even harder to swap fans out.
Also with the front fan out, just disconnect the radiator fan from the motherboard and plug the front fan into that header. Power it on and see if you get a similar error. If not, then you can put the ML120 Pro in the front, and use the Dell front fan for the radiator.

Already did what you said and get the same error using the front fan as a radiator fan and the Corsair to the front header, also I notice that the fan that Dell uses has different versions the hardware is same just different versions A00 and A01, so my guess is that the R8 uses like a version A03 that they just update changing just the RPM from Bios to Bios.
