I contacted Microsoft and here is the statement the company has provided to Pureinfotech on this incident: In reality what it seems to be happening is that there is some sort of issue that causes to trigger a temperature gauge icon to a small number of users running the Core i7 version of Surface Pro 3. However the issue still related to heat, Microsoft has packed a quite powerful processor in such small form factor device that, of course, it’s going to cause serious fan spinning or auto shut down when necessary to keep things cool. So don’t be surprise if things gets hot with the Core i7 model. The i7 version of Surface Pro 3 is a first-of-its-kind tablet delivering i7 processing power in a thin and light package. As such, the increased power calls for the fan to spin more regularly and at higher speeds – and for the unit to run slightly warmer. If customers have any questions or concerns, they should contact Microsoft Support.” Microsoft has yet to specify when a fix will be released, but as we are getting closer to the September Patch Tuesday, it’s possible that users will get a Surface firmware update in a couple of weeks.  All content on this site is provided with no warranties, express or implied.
