Alienware Aurora R5 - CPU Fan 100%
Staring a new thread with some more updates and new issues.
Upon receiving this machine, I removed the i3 6100 and put in a 6700k cpu. I used the stock air cooler while waiting for my Corsair H80i GT to arrive.
First off, upon shipment, the CPU fan has been stuck at 100%. (CPU temps between 20-30c and idle machine).
Tried a different CPU fan from my x51 and XPS 8700 - both at 100%. Applied new TIM a couple of times - no luck.
I have tried all the old tricks, uninstall, reinstall ACC...nothing works except to put command center to manual. Doing so gives you ZERO cpu fan control and the machine overheats when under load.
While we can blame the i7 K series CPU, it does the same thing with the i3.
Doing the ePSA testing, Top Fan & CPU Fan fail.
I received my H80i today and installed that. Its a very tight fit but you can close it up. Need to remove front 3.5" HDD cage and run the hoses up that way.
Radiator mounted to the upper cage, fan mounts to the radiator. Did not use the fan bracket for this install. This 120mm cooler is probably worst case scenario for hose length and stiffness but it works!
Lots of options for adding your own liquid cooling.
So I proceeded to hook this up exactly as I have seen the liquid cooled models online.
The fan on TOP_FAN and cooling pump on PUMP_FAN.
Upon boot up, pump failure.
So I am out of options and things to try. Kinda hoping this is BIOS related.
PS - Alienware please ditch the 1982 BIOS and get current.
Moving on, if you buy this machine with the intention of upgrading the motherboard later, the AlienFX lights are now tied to the OEM motherboard - no more MIO boards.
This is a change from your previous generation Auroras and Area 51 machines! Many of us hold onto them for years and buying a motherboard through service parts....$$$ ouch.

HockeyTown is ok now, these diagrams are for you the reader
pricey alien-kooler uses Top_FAN + PUMP ... far right CPU_FAN header is unused
Fan-Sink: Top_FAN + CPU_FAN used; central Pump header unused
edit: Hockey will give us this update in a few posts below:
My Suggestion for H80i GT
"I might be tempted to install the h80 3pin pump connector onto their CPU_fan header, just to see if it gets 12v/ground, & plug my fan into its included fan connex. if possible, try that, power up, enter Bios, look to see if it keeps track of cpu temp: if plugging into the cpu_fan header leads to overheating, if your cpu approaches 70c-80c at idle, shut off, hold power button in 5seconds etc"
above, my 130watt 4820k wants to sit around low 30c at idle
... the idea here is liquid-cooling should give us a CPU temp between 25c-50c at idle (simply powered on), where 70-80c is way out of spec (denotes a problem) & never ever let your cpu broach 80c - 100c at idle --> shut down between 60c & 80c & figure it out 1st
Hockey -to- Cass PM: "I tried your last suggestion & it did work. If I plug the fan into the H80i fan connection, it does report a signal.The issue here is the top fan I'm using which normally hooks to TOP_FAN then reports an error. So in the end, you have to have fan signal at both TOP_FAN & CPU_FAN headers"
H80i GT & standard H80i + H80i V2 are set up so the fans plug into the pump, ok?
fans into the pump
not into the motherboard fan header
'Basic koolers' (like Area-51 K31VH or Corsair H75)
Although they have the same basic 3pin fan (pump) connector as the H80i GT, the fan(s) need plugged into a motherboard fan header. It isn't certain right now why Hockeytown has or had an issue (100% fans + pump failure ie no power to pump?) while using a motherboard with a non-shipped liquid kooling option now in combination with an aftermarket kooler, but below are a few ways to ensure your pump gets 12volts / ground (ie help get it the constant 12volt power it needs).
How to appraise & 'fix' 100% fans is a separate issue: ensuring water pump runs & CPU is kooled = your #1 priority
were it me, to cure the reasons for pump failure & get guaranteed 12volts/ground (+ tach-rpm), I might try one of these:Oh that's right, they shorted you on your 3rd top row accessory Molex / peripheral cable right? A little gadget like above is exactly why it is sooooooo unkool not to give you a full cable set with your estimated $150 850w power supply
- shielded variation -
eBay: 4 Pin Male/Female Molex to 3 Pin Male Fan to 3 Pin Female Fan ($2 + $11.59 mailed Illinois)
yellow RPM / Tach wire to mthrbrd pump header + 12v / grd (red / blk) from Molex 4pin to pump
$17, overkill, but has reqwired RPM signal to motherboard + SATA power
eBay: Swiftech SATA to 8 x PWM PC Computer Fan Splitter Adapter Board w/ RPM Out Cable
A search on eBay for a SATA to Molex adapter might reveal one of these for $5:
naturally your SATA cable pair should be wired like my sata cable pair; if you compare notes here with me, I may be able to make you a replica Molex / peripheral cable, in the event the Area-51 93CYT cable meant for the 850w is unavailable, which Dell chat informs me it is

I found a temp workaround for now.
Hooked up an old Antec 80mm fan that has a 3 way switch for RPM. Plugged that into the CPU_FAN header and set it on the lowest setting. Its sitting on the bottom for the PC for now.
Calling Alienware tech support would be a waste at this point. Nobody seems to know anything about this machine and until other people have the same issue, isolated incidents are not looked into.

Was the cpu fan at 100% when you had the i3 original stock cpu in there before replacing it with the 6700 ?

Yep, stuck at 100% with the i3 as well.
Cass - I replied to your PM. Your suggestion did work with the Corsair H80i cooler.
The downside here is that fixes "pump failure" but then I get "Top Fan Failure". I need to have a fan on both headers to get rid of the error.
There are no options in BIOS to turn off these warnings.
Sure would be interested in what Dell/Alienware has to say about this.

Very bad , the Alienware Area 51 r2 also makes hair dryer sound with fans at max speed for 15 seconds if you turn it on with plug still plugged in Mains socket even with liquid cooler.

Hock my friend , can you kindly take a photo of all the case fans in the system ? How many are there and they the same as Area 51 r2 anyone knows ?

New Bios 1.07 issued Aug 26th might help, see below
today @darkofdoge tried the i3 -to- 6700k swap, got the @Hockey 100% fans issue & tried the manual fans cure, which settled things down
posted in his thread:Aurora r5 stock heatsync having problems of voltage with modular evga 750 watt psu
From there, CPU temps will need to be monitored, due to the i3 heatsink & now slower fan speed, where we'd expect the 95watt TDP i7 to heat it up in there, driving the fan back to 100%: a better cooler was recommended to combat heat after the i7 K swap ...
a follow-up: @Hockey sent me a few PMs
*** "Yep, I installed 1.0.7 on my son's R5 (i3 6100 base config) this weekend. There is now a CPU fan control in ACC under your thermal management. Before you only had top and front fan control so finally a fix. I do believe the BIOS is set to run the fan at 100% if it detects a K series CPU.
If you notice in the bios, the overclocking feature only activates once a K series is installed. This might also trigger a different fan profile because the assumption here is your running liquid cooling. Would still be nice to have some control in BIOS for fans"
*** "I ended up swapping out the Corsair H80i GT for a OEM Asetek 550LC pump. This solved my fan issue & I'm now able to hook up via factory setting (Top_fan + Pump_fan) & no errors"
*** "I did find you can easily add an 80mm internal PC fan to the 3.5" HDD cage. If you pull that cage out you'll see mounting holes. Some options for internal circulation (though no fan header to hook from)"
passive mosfet / vrm / chipset heatsinks which use thermal tape were also an idea on those non-K motherboards which do not get a heatsink, due to the shady practice of Dell cost-cuts

I got confuse here. Did the pump failure or the top fan failure finally fixed with liquid cooling? From the last post, it seems @Hockey removed the liquid cooling finally..

Hi there,
Maybe this is another type of problem but it's my issue with R5. Yesterday i was trying to replace my i7 6700 non K to 'K' model which allow me to OC. I wanna say everything was made under stock air cooler which is not best quality after all. After Replacement and plug Air Cooler to CPU_FAN weird things happen. The Computer itself start to run at 100% speed of Fans. Windows boot up and ACC launch i could manually change TOP/FRONT RPM FAN but option where i could change RPM of Air cooler Disappear and Pump_Ready shows up!? I just wanna say one more time i never had and never plug in any Liquid cooling to motherboard but here we are. I changed back processor to non 'K' and PUMP ready option disappear and CPU_FAN option to manipulate RPM again shows up. Can someone tell me what to do to remove that jet spinning of FANS at launch and have option CPU_FAN avaible under "K" CPU?
