Here is my list of parts for reference http://pcpartpicker.com/p/2Ghqf. I've had this build up and running for about a week when I found this switch on my motherboard called GPU Boost switch. It has three setting; off, gpu boost and cpu ratio boost, and gpu boost and cpu bclk/ ratio boost. Now I had no idea what these meant, but boost sounded cool so I switched it on and powered up my computer. This caused my processor to start heating up rapidly and immediately. It went from about 30C to 70C in a minute or two, which was extremely concerning, so I powered it down. I figured it was the switch, so I turned it off, and tried again. Same issue! I don't know what to do. I reset my CMOS in case I had changed a setting accidentally, but no luck.

Please help me!

Note: I am planning on overclocking this processor in the future. If the solution to fixing my heat problems involves overclocking it/ changing BIOS setting, so be it. I just don't know too much about that as I've never OC'd before.

Thanks in advance!

I have reset the motherboard to default by resetting the CMOS battery. After looking under my heatsink to make sure it was on right, I found that only half of it was contacting the processor. I'll update to see if this fixes it.

Thanks!

No luck. The heatsink is fully contacting the processor and both are seated well. Booted up and the cpu is quickly rising from 30C to above 60C very quickly. So i've got the bios setting all reset to default, and the processor and heatsink seated correctly, and still problems.

This is pointing in the direction of a poorly seated CPU/heatsink. Or, the flow in the water cooling loop is not right.

I've checked the seating of the heatsink and cpu twice, they are fine. I'm not sure if the cooling loop could be a problem, there's only one way to hook it up. It's a closed system, so I can't really flush it out. It comes pre filled and all you do is hook it up.

I suppose you're right. I'll have to look at the cooling system a little closer then. Question; what should the CCVIN (most likely called something else) be? Mines at 1.712v. This seems high, but I am a complete amateur.

It could be due to a bad/faulty motherboard VRM, or bad voltage calibration. From the temps problems that you are having, the CPU is definitely getting overheated.

One thing to try is updating (flashing) the BIOS if there is a BIOS update at Asus' website for this motherboard. Follow the manufacturer's directions in order to do this. Caution is advised.

Another thing that comes to mind is that the 'Boost' switches may be stuck in the ON position even though you tried to put them back in the original position. With the power OFF try to activate and de-activate these switches to free them up.

If this does not solve the problem, try to RMA the board.

So, stupidly, when I took off and reseated my CPU cooler, I had unplugged it. I then forgot to plug it back in when I turned the computer back on. Meaning the problem was the heatsink seating! So thank you for bringing up that suggestion. I'm not sitting at a cool 30C at idle. Cheers friend!
