STEP 3: ETI REFLOW PROCEDURE:
ETI Reflow:
As part of installation, the Indigo Xtreme ETI must first be heated with the CPU running under load in order to reflow (melt) the PCMA.
1.
Connect up all liquid lines to the water block.
2.
Orient the computer such that the motherboard and CPU are in a horizontal position.
3.
Turn on the liquid pump.
4.
Boot the computer. Clock frequency and voltage must be set to default (stock).
5.
Use a CPU temperature monitoring program (such as SpeedFan™) and select the graphing option to track the profile of all core temperatures during reflow. Be certain the graph is open
with all core temperatures selected before proceeding to the next step.
6.
With the computer running, turn off the liquid pump.
7.
Exercise the CPU with a “burn” program (such as Prime 95™) to generate adequate heat for reflow. Multi-core CPUs require one open copy of the burn program for each core.
8.
Follow the average core temperature profile (with SpeedFan) illustrated in the graph and corresponding tables below for your particular water block.
Full copper/nickel water blocks will require longer reflow times.

1 All burn programs have been activated and
liquid pump has been turned off.
All burn programs have been activated and
liquid pump has been turned off.
2 Core temperatures will immediately rise to
peak of ~85-95°C.
Core temperatures will immediately rise to peak
of ~85-95°C.
3 Core temperatures will quickly descend within
seconds of activating burn programs.
Core temperatures will somewhat stabilize for a
few minutes and then slowly descend.
4 All core temperatures will drop to a Bottoming
Point (lowest temperature).
All core temperatures will drop to a Bottoming
Point (lowest temperature).
5 Following the Bottoming Point, average core
temperatures will slowly rise again.
Following the Bottoming Point, average core
temperatures will slowly rise again.
6 Once the average core temperature has
reached ~80-90°C, de-activate all burn
programs.
Once the average core temperature has
reached ~80-90°C, de-activate all burn
programs.
7 All core temperatures will again drop to the
second Bottoming Point. Once the lowest
temperature is reached, turn on liquid pump.
All core temperatures will again drop to the
second Bottoming Point. Once the lowest
temperature is reached, turn on liquid pump.
Intel multi-core processors have built-in protection (Adaptive Thermal Monitor) that
prevents the processor from exceeding maximum core temperatures, thereby
preventing any damage to the CPU.
Avoid any bumping or excessive pressure on the heat sink/waterblock and keep the
computer in the horizontal position until the average core temperature has dropped
below 60°C.
If the average core temperature does not follow a similar temperature profile as seen
in the previous graphics, then improper reflow may have occurred. Proceed to
“Removal” and re-install a new ETI.
The interface is highly thermally resistive without a complete reflow. Failure to perform the exact reflow procedure may result in unacceptable thermal performance. A video
demonstration of ETI reflow can be found at EKWB product page: http://www.ekwb.com
