new watercooling loop help

[Blake mcBlake]

Just finished my first custom loop. I have dual 240mm rads cooling a 4770k and a titan x. (4770k @ 4ghz 1.25v titan x + 200 core) the gpu runs nice and cool under load never getting over 56 c...however my CPU is jumping around i just ran aida 64 and 2 cores reached 93c. I have re-applied the TIM and evacuated as much air from the loop as i think i can. any ideas on what to look at next?

What waterblock are you using for the CPU and also what are your idle temps if those are also high then you most likely have a bad mount still.

it's the ek supremecy mx. idle temps under 40c but watching youtube and checking forums HWmonitor says i have spikes up to 56c

you still have air in the loop...could be in the CPU block itself or the pump or even the radiator......have you made sure all ports are sealed and then tilting the PC with the pump is on and giving it a slight shake.

Let it run for a few days to have all the air go out of the loop first and see if the temps drop more if they don't it does sounds like a bad contact onto the CPU.

yea, a couple times. I'll give it another go i suppose and maybe just let it sit with the cap off for a while

cap off won't dislodge air. I have noticed that new components like blocks and radiators and especially pumps tend to work best after a few empties and refills to sort of lubricate the insides.

 

Try tilting the PC is opposite directions to dislodge the air while turning on and off the pump, you will need to use a jumper for the PSU and disconnect sata, gpu and MOBO auxiliary plugs so as to not mess you the components. I remember one i had to use a drop of dish washing liquid in a loop to get a the plenum air out of a radiator, then i had to drain the loop clean it and add fresh coolant.

Add more coolant to the loop (until it reaches max). That works for me and could cut down like 5-10 degrees.

[Blake mcBlake]

Been playing with it. I had a couple small burps but the water level is basically the same as it was.

tilt your rig left and right when the loop is running make sure it does not leak first btw. 

or try reapply the thermal paste again maybe with better quality one or different method of spreading the paste. 

I spread with my finger evenly and it does way better compare to pea size in the middle at least in my case. and god that titan x tho.

Here's what it looks like. Is the orientation of the res/pump and/or the way the loop is routed could have anything to do with it?

As long as the pump isn't sucking in air it's not a problem having it sideways, also what direction of flow is your loop going the MX series block does have a inlet and outlet port that needs to be followed, the center is inlet the right port is outlet.

FML. I have the Right as the inlet

Nice.

That might help 

You could just switch the flow on your res/pump to have the loop go the other way the tubing doesn't cross the waterblock.

That's what i get for tossing the directions as soon as i took it out of the box...Thanks for bringing it to my attention!

Okay I switched the plumbing the correct way today. Still getting temps of 75 ish when playing gtaV. Still seems way too warm to me

What do you get with adia 64 stress testing, it's better than before it seems but as said a tad on the warm side still.

Just ran Aida temp jumped to 89. It only does it on the last 2 portions of the test. And it does it extremely quick

I'll play with it more tomorrow I guess but I actually took the cpu block off of the cpu still attached to the loop and spun it and shook jt about with the loop running so idk how it could still be housing an air bubble

See what happens in a day or two but yeah it still seems a bit warm, if the idle temps and mount are good then it could possibly be the CPU's ability to transfer the heat into the waterblock and fluid being the limiting factor.
