I just finished my first build with the help of the wife. I am using the Kraken x61 liquid cooler right now plugged into an i5-4690k CPU. My temps are quickly getting over 80 degrees and that is just from sitting in BIOS. I haven't even gotten an OS on it yet.

(1) USB from pump is plugged into JUSB 2

(2) SATA is plugged into the SATA cable coming from Power Supply (also the 2 fans near radiator are plugged into the same cable

(3) The last plug on the pump (3-pin - power?) has been plugged into both CPU FAN and SYS FAN

(4) The brand new kraken x61 has been attached to the CPU following their instructions - however when we first attached it to the CPU, we removed it for 5 seconds and saw some thermal paste on the CPU. It was a very small amount and we quickly put it back on. Not sure if that messed something up.


I thought I should hear gurgling to see that the pump was working, but I haven't noticed any. Any help would be appreciated as I believe this is the final step.

You know it looks like to me you may of installed the Kraken X61 water cpu cooling block with the wrong type of standoffs for the type and cpu socket the board has.

You need to double check what type of cpu socket the motherboard you bought has.

Intel cpu socket 115X or 1366

Or intel cpu socket 2011.

You have three sets of standoff pins used to mount the water block of the Kraken x 61.
You must make sure you use the right length of standoff pins provided with the kraken x61 as one set of standoff posts are slightly longer in length than the other set provided and must be fitted to your motherboard with the matching cpu socket the motherboard states it has.

Or when you clamp the cpu water block down via the four thumb screws...

All sounds fine except the pump should only be connected to one Header, the cpu fan header, so possibly this double connection is causing pump to not work, If you feel the pump housing it should be no warmer than the hoses or the radiator, If it feels much warmer around that pump, this would tell you the pump is not pumping the hot fluid away

Sorry for the confusion on my wording, what I meant was that I have tried them both separately. They are not both plugged in at the same time. I really don't think that the pump is working at all as it doesn't make noise, the tubes aren't vibrating and the whole unit is cold.

This is probably it.
Compromised thermal paste application.

Or when you clamp the cpu water block down via the four thumb screws provided the face plate of the cpu water block does not seat firmly or flushly to the heat spreading plate of the cpu it`s self.

You will have a small gap between both.

Click on the link bellow to check you have used the correct set of standoffs for the cpu socket type your motherboard has.

If you fitted the wrong ones in length it explains why the cpu may be reaching 80c at idle in the bios.

I appreciate the in depth response. I double checked just to make sure, but I am using the longer screws (115x) for my 1150 mobo (http://www.newegg.com/Product/Product.aspx?Item=N82E16813130801&cm_re=MSI_Z97S_SLI_Krait_Edition_LGA_1150_Intel_Z97_HDMI_SATA_6Gb%2fs_USB_3.0_ATX_Intel_Motherboard-_-13-130-801-_-Product). So it would seem like I did do that correctly. I was so hoping that was the issue.

Thanks again for taking a look.

You say the unit is cold? even when the cpu reaches 80c it has to be getting warm?
Just that makes me think bad contact on cpu and the fact it warms so quick, in bios? If the answer was pump not working but it had good contact, the pump/heatsink case would get mighty warm and the rest cold, but you said all cold? Hmm

Those pumps don't gurgle, they are drowned by the fans easily, the led lights up on the pump?
You didn't change settings on the cpu, overclock it? Stock setting and sitting only in bios with that large cooler should have it sitting in the high 20s/low thirties and until you fix this i would not run the pc. the board is reading celsius and not fahrenheit?
