Hey guys, so I received all of the parts for my new build yesterday and have just finished getting it all put together.

After a few trivial problems i get to the BIOS and I'm getting a CPU fan error, I press F1 to enter the BIOS and it says there is no CPU fan connected and the CPU temp steadily starts climbing so i decide to switch off.

I'm running a 4930k on an Asus Deluxe X79 2011 board with an H100 Extreme CPU cooler.

The two H100 fans are plugged into the pump block, and the unit is plugged into both the CPU fan header and into the power via the 4 pin molex.

Both fans are visibly working and the block lights up, yet the temp rises to unacceptable levels just sitting in the bios.

Anyone have any potential fixes?

My specs
-EVGA GeForce GTX 780Ti Superclock 3072MB GDDR5 PCI-Express Graphics Card
-Corsair H100 Extreme CPU cooler
-Kingston HyperX Beast 64GB (8x8GB) PC3-14900C10 1866MHz Dual Channel Kit
-Intel 4930K 3.40GHz (Ivybridge-E) Socket LGA2011 Processor
-Asus X79 DELUXE Intel X79 (Socket 2011) DDR3 Motherboard
-Samsung 250GB SSD 840 EVO SATA 6Gbs Basic
-Be Quiet Power Zone 850W '80 Plus Bronze' Fully Modular Power Supply
-Corsair Carbide 500R Midi Tower Case - White
-Microsoft Windows 8.1 64-Bit
-Seagate Barracuda 2TB 7200RPM SATA 6Gbs 64MB Cache
-Asus 24x DVD±RW DRW-24B5ST SATA ReWriter - Black
 
Its 100% your h100i's pump connection..(i had this sisue with my H50)

You say you've connected the pump cable to the motherboard fan header, which one have you connected it to?

One fan header is PWM (normally) and will only run at 50%, where as the other (the one by the PCI-E slot) will run 100% thats what you need. Or connect it straight to the PSU via molex.

I've connected the 3 pin socket to the 4 pin cpufan header as well as the 4 pin molex to the psi, is this correct?
 
Dunno if its just an Asus issue but I have had three Asus boards and everyone of them i have had " beep beep beep ....CPU FAN ERROR " ...but the fans are going round...so i just go into BIOS and choose " Ignore" for the CU Fans monitor .
 
I've read many reports that match what you're saying but although the fans are spinning the pump cannot be working because the temps are reaching 70+ just in the bios
 
Is your 3 pin in CPU_FAN_1?

Im pretty sure thats PWM. So you can either go into your PWM setting and set it too 100% or connec the pin to molex via an adapter.

That should solve it.

Like i sad, i had the same issue with my H50, rising temps in BIOS. :)

Ok thanks I'll give that a try and report back.

There is an unlabelled 3 pin header near the PCI slots that looks like it would take the fan 3pin fan connector, would this be the 100% one you mentioned?

Also if i use an adaptor and connect it via molex do i still need to have the other cable connected to the PSU as well?

Rambling abit, hope you understand what I'm saying! :)

I completely understand.

Im pretty sure the one by the PCI-E slot is the full 12v one (it is on miy board) Tough it does look messy having the wire running down the board (picky)

Im not sure but id have both connected, just incase. (thinking about it the molex maybe for the lighting).

Hope this helps. :)
 
Tried your suggestions, unfortunately to no avail. Trying both the 12v one and plugging in via molex adaptor the fans fire up as before yet the temperature rockets in bios. Could it be a fault with pump itself or is there anything else i could try?

Appreciate the help
 
Hmmm this is tricky.. Are you able to set the PWM setting in the BIOS to 100%? Try it that way?

Im low on ideas.. it may be a faulty pump but we have to try everything else first. :)

Any idea of where i find the PWM setting? I feel like I have limited time in the BIOS because I don't want the CPU to overheat.
 
Ok I'll look into that, so for now I'm best leaving it plugged into the CPUfan header?

I'm assuming if the CPU gets too hot it'll turn off anyway?

Cheers.
 
Yeah leave it in the fan header for now and see whther you can get the PWM working.

It will do but its best to switch it off yourself before it reaches 85-90.
 
The only options I have for the fans is normal, manual or turbo but the CPU fan isn't detected at all so it just says N/A

You can press the front of the H100 unit which is supposed to increase the fan RPM but this doesn't appear to do anything?

I'll try and get some pictures to show everything to possibly help show everything
 
Ok just to show the current setup, just incase I'm missing something glaringly obvious which is entirely possible :)

This is the first cable that is coming out of the main H100 block.


This is plugged into here:


The second cable coming from the H100 is this:


Which i have connected to the power supply


Using this adapter cable


The two fans that come with the H100 are both plugged into the top of the H100 unit and both spin when the system is powered on.

On boot....


BIOS
 
when I added watercooling to my asus board I had to go into the bios go to cpu fan speed and switch to ignore. not sure about your temps as I put my rad fans onto a fan controller.

Yeah I've heard setting it to ignore will stop the CPU fan error but mine can't be working at all because of the insane temps I'm getting.
