A new round of emails are going out to some Roku 4 owners, occording to Cord Cutters News, informing them that their streaming box is being recalled due to “a manufacturing glitch.” Recently after the device was released, customers began receiving similar emails, so this appears to be a continuation of the same initial recall. Roku is not divulging any information about the specific reason for the recall, but it’s likely due to some units leaving the factory without a CPU thermal pad installed. The thermal pad is what ensures the heatsink, a metallic block that extracts heat, comes in contact with the CPU. Without a thermal pad, the Roku 4 may not dissipate heat efficiently, resulting in the device’s fan working overtime. A member of the AVS Forum opened up their Roku 4 to confirm there was no thermal pad installed, while the pictures from an Amazon reviewer, who did the same, show thermal pads installed on the CPU. The owner of the Roku 4 without a thermal pad reports his device’s idle temperature was 77°C with the fan running at 85% speed. After installing his own thermal pad, idle temperatures dropped down to 50°C, resulting in the Roku 4’s fan turning off completely. If you have a loud Roku 4, check your email for a recall notice. If you don’t mind voiding your warranty, and want to take matters into your own hand, you can crack open your Roku 4 yourself to see if yours has a thermal pad or not.
