Apologies in advance if this ends up being something stupid that I have just overlooked. It is my first time delving into a form of watercooling on my main system and I'm having some teething issues.

First off, the AIO is cooling an i7 5930K, currently running at stock while I sort this issue out. The fans are in their default pull positions, nothing has been changed from opening the box. I have the radiator set up in the top of my case and the connectors included are connected to the CPU_Fan header on my Asus X99 Deluxe motherboard and the other directly into a PSU SATA cable. The red light on the predator is also on.


The issue I am having is that at idle my temps can vary between as low as 28c to as high as 50c, with 100% loads temps anywhere between 55c and 85c.

The consistent thing about this is that the motherboard and programs like speedfan and reporting that the CPU fan is running at only 390-410RPM regarding of the load or temperature and I can confirm this visually by seeing how slow the fans are turning.

I am currently running a prime95 stress test as I write this and my temps are between 79c and 84c and the CPU Fan (Reading from Speedfan) is still only showing 416RPM.

Having turned off all case fans and GPU fans to make it as silent as I can, I can very faintly hear water moving in the pump, but I'm not too sure if I can hear the pump itself really working properly.

Apologies for the wall of text! Any suggestions here before I even consider RMA'ing it?

EDIT - Having ran the prime95 test for only 10 or so minutes, my CPU temps were actually hitting as high as 92c on some cores which is worrying.

Try setting the pwm header to full power, and move the case side to side and end to end.

Might just be air, also check the fluid level, I have a 5930 on a 240 Pred and it works reasonably well.

On BIOS turn all PWM to 100% and turn off the thermal monitoring. Then use a windows app to set the desired fan speed. (there is way to set up curve etc).
At constant 70%-80% fan speed you should be happy, while is still relative quiet.

At that speed is powering a 4930K @ 4.5 and an overclocked GTX1080 @2164. While previously, cooled a 4820K @ 4.8 and a Fury Nano @ 1120 for 9 months straight :)

Atm you run the fans at 25%-30% speed, you should never run it bellow 50%.

The whole unit itself, is powered by the Sata connection. So the PWM_CPU header is the only thing telling the Predator, to either speed up the fans and pump, or slow them down.

As neither the fans or pump seem to be working correctly to temperature, it may be something in the bios, that's not set up properly ?

Can you try another 4 pin PWM header on your motherboard ?

Might be also worth trying a different connector on your Sata cable, or another Sata cable, altogether.

Hi all, thanks for the comments.

@Rustyone - In the BIOS, I have tried setting it to 100% and also have tried moving the case/cooler to try and get it rolling. Neither seem to have had an effect.

@Panos - In regards to the fan speed in windows, I have also tried this and it doesn't seem to be affecting it at all.

@Drex - I have tried changing the sata connection, even to one where nothing is plugged into it and is only plugged into the PSU and the predator. I have also tried different fan headers to no affect, even tried plugging it into one of the exhaust fan headers in my case to then try and manually control through the case (EVGA DG-87).

I can't really see anything in the bios myself that could be doing this.

So you have the system running at 100% fan speed? If you still have temp issues, then clean the CPU and it's block and re-apply the paste making sure is fully covered and well screwed all the bolts...

Which paste are you using?
 
Something is definitely not right there. I run the fans at 25% on mine (under 65C) and at idle on a 5960x at 4.6GHz temps are sub-30C generally. Under load at default speed on a 5930K temps should barely be above 50-55C.

I would be checking that the CPU block is mounted correctly as Panos mentions above as you can have quite a large temperature difference if its not quite level.
 
@Panos - Yes, 100%, but it doesn't seem to make a difference. I am using Thermal Grizzly Kryonaut, was evenly applied and I certainly have never had issues applying paste in the past.

When I start my PC, as I have done this morning, my temps are as low as 27c, but after 30 minutes or so of, well not much at all, it rises to around 45c, but any activity on any of the cores bumps the temps up quickly.

@reef - AFAIK, it should be on perfectly fine, but I will give that a go this afternoon to see if anything is wrong.

Thanks again folks!

Do you have pull or push configuration? If pull, do you have positive airflow in the system?
Can you hear/see the fans working at 100%? Have you tried to change the PWM socket?

Did you change the Sata cable to make sure that gets power?
 
@Panos & Rustyone - It is in the default pull configuration at the moment. I cannot see/hear the fans running at 100% at all, it definitely looks like it is going at the slow 400 odd rpm that is being reported.

Not used HW Monitor before, but I believe this is the correct results?

Yes, changed the Sata cable, no effect.

450 is barely 25% fan speed.

On which PWM you have connected the Predator to the motherboard?
Have you tried to change the socket? (the cable is pretty long).

Use speedfan application and make sure all PWM are set to 100% if not, go to the bios and set it.
Have you turned off the health monitoring
