# Heat sink for WizFi630

## Question

Asked by guenter on 2014-04-24 in Wireless.

Hello,
we are using the WizFi630 module in a aluminium housing.
Environmental temperature range for our product is specified from 0 to 40 degree Celsius.
We noticed that the temperature of WizFi module (more precisely the Ralink RT3050F) runs to 50-55 degree C, when operating at room temperature.
Is it better to use the WifFi630 module with a small self-adhesive heat sink to increase life expectancy ?

Best regards

Hi

Temperaturee of WizFi630 module runs to 50-55 degree C without Heat sink.
But Heat sink is effective to reduce heat of WizFi630.

Thank you.
