Technical Bulletin 2-9-16

Subject: X2 series CPU looking kits

1/ Scope
We have identified a potential issue with an undetermined number of PWM splitters (revision 1) included with the above kits, and shipped to consumers and US resellers between January 15th , and January 28th.

2/ Nature of the issue
Weak solders joints of the power and signal cable to the PCB may cause wires to easily come loose.

3/ Symptoms of a defective unit
Some or all devices connected to the splitter will not operate at all or operate erratically.

4/ Resolution
Recall of the potentially faulty revision 1 PWM splitter, and replacement by revision 2 of the splitter.

Temporary cooler operations:
a. We recommend discarding your existing revision 1 PWM splitter.

b. The CPU cooler is thermally functional without use of the PWM splitter. While waiting for a replacement, customers can connect their fans to the motherboard auxiliary fan headers for instance, and connect the pump pwm 4-pin connector to the motherboard “CPU_Fan” header.

Permanent cooler operations: replacement of the device by the new revision 2 PWM splitter available now with the RMA procedure described below.

5/ RMA procedure:
Please contact us either by email at or by phone at 310-763-0336 or 888-857-9438, and all efforts will be made to send a free replacement unit within 72 hours by first class mail.
In order to ascertain that the unit is eligible for replacement, we ask that customers provide a picture of their existing splitter, the serial number of their pump (located on the label affixed at the back of the pump), and a copy of the purchase invoice showing a current ship to address.
How to make sure that the splitter qualifies for replacement: the potentially faulty units are ONLY revision 1 of the splitter. Revision 2 is NOT subject to recall. To recognize revision 1 from revision 2, please observe the top surface of the housing where the connectors are located: revision 1 has a flat top; revision 2 has a raised center section, as shown below.
