Received my order from PPCs on March, 30. One of 80 mm Xigmatek fans had some white stains on its blades (looks like glue used to secure the LEDs in place)
E-mailed them about the problem the next day and the only things I received from them till now are 2 letters:
The first:

Hello
Sorry to hear this. Since it would cost too much to send back it would be best to ask Xigmatek on how to solve. I have copied them on this email.

Sam, (Xigmatek)
Can you help?

In 5 days I emailed them again, stating that haven't received any response from Xigmatek and asking for a replacement or refund. The response was as follows:

Hello
the problem is you would have to RMA this back here and pay for return shipping (we dont cover RMA shipping on International orders) and so you can see it will cost more shipping then the fan is worth. So that is why we are seeing if Xigmatek can help.

Will email them again.

Tomorrow will be 5 days since I received the second reply from PPCs and still I can't hear anything neither from them, nor from Xigmatek
