Custom Water Loop vs AIO - Temp Difference

post #1 of 9
Thread Starter 
Before I went full custom water loop I was using NZXT Kraken X60 AIO for my CPU and getting 50c - 55c under full load. Now that I went full custom I'm getting 58c - 65c.

CPU Specs

CASE - Corsair 750D
MOTHERBOARD - MSI z77 Mpower
CPU - i7 3770k @ 4.5ghz
MEMORY - 16g DDR3 Corsair Vengeance
GPU - 2x MSI GTX 780 Twin Frozr SLI
PSU - Corsair AX1200i
SSD - Samsung 840 250gb
OS - Windows 8.1 Pro

Custom Water Loop Specs

CPU - XSPC Raystorm Waterblock
GPU - 2x XSPC Razor Waterblock
RADIATOR - XSPC 420mm // XSPC 280mm
PUMP - Swiftech MCP35x
RESERVOIR - XSPC Photon 270mm Glass Cylinder
TUBING - 1/2" ID 3/4" OD XSPC FLX PVC UV Blue
FANS - 7x 140mm Noctua NF-A14 PWM

LOOP ORDER

RES>PUMP>280MM RAD>CPU BLOCK>420MM RAD>GPU1 BLOCK>GPU2 BLOCK>RES

My guess is I might just have to reseat the CPU water block, maybe I have a bad thermal transfer between the chip and block.

Suggestions?

Are your GPU temps lower?If your GPU temps are better as expected then I would say it is a bad CPU block mount.

Oh yeah, GPU temps went from 70c under load to 30c.

Definitely a bad CPU mount. What thermal paste are you using? Make sure to use the pea size method for best results.

I'm using Arctic Silver 5, I used a pea size the first time but i think it didnt mount properly because the block was sliding around finding the holes. I also have the thermal paste XSPC gave me for the blocks, but I've always used Arctic Silver 5 and had good results.

Yea that is fine. The sliding probably did it as Arctic Silver spread VERY easily. Try to remount. Might take a couple of tries.

Sounds good man thanks for the input, ill post back when I retry, hopefully temps are better so I can OC more.

BTW just noticed we have the same MOBO, CPU and CPU water block. thumb.gif

Indeed we do lol. Wish I had your GPUs, but I am waiting until the next generation to upgrade.
